This video has to be my favorite one of all, especially during the ignition and burning phase. The oil and air mix easily and then the square tubing facilitates the flame via a Venturi effect. I love the howling noise it makes too.
I was just looking at this setup yesterday thinking I should do another vid with it. Needs some new plastic Tubing which I don't know if I have or can get but I will look into doing another vid of it soon.
Now this is something that you could use to make an oil burner heated deep fryer with, mount the cooker far enough away from the dragon-breath side and it would be able to work just fine. Use old oil to heat new oil to cook in that will, over time, become used, which would then be burned to heat new oil... The circle of FIRE... Glad your uploading videos again.
I've just built one of these. Not the exact same thing but same theory. Works like a charm. Within an hour of getting it finally assembled I was melting aluminum. I think I used about 4 gallons of used engine oil in an hour. It's not very demanding on my air compressor. I'm using 3/16" lines because that's what I had laying around. I think if I want to go hotter I have to go with bigger lines. Awesome build and awesome video. Thank you for sharing this.
i dont mean to be so off topic but does any of you know of a trick to get back into an Instagram account? I was stupid lost my account password. I would appreciate any assistance you can give me
@Mason Arturo thanks for your reply. I found the site through google and I'm trying it out now. I see it takes a while so I will reply here later when my account password hopefully is recovered.
huge thanks for uploading this video, been put off building my own spray type nozzle furnace for melting cast iron as all the ones i have seen use expensive fiddly bought in ones with loads of needle control valves for everything.i can see why you would want loads of control and the ease of buying in a valve but i couldn't see the simpler way to build one and now i can. many thanks again, keep up the good work !
+The Home Machinist You are welcome. Its very rewarding to know people are putting these ideas to work and benefiting from them. Really makes it all worth while. If you are able to video what you make, please let me know when you have. it's great to see what people do in action.
+Oil Burner HI oil burner, have built my nozzle, using gravity syphon feed, problem is it seems to be blowing out both nozzle and feed pipe. if i take nozzle out works great at syphoning but rubbish at atomising/ misting. i am using waste commercial veggie oil. playing with the pressure seems to do nothing. only thing i can thing of is using pressure feed for oil like in this video ?
Hey me and my friend used your instructions and made a oil burner in this style and it works great! We built our aluminium furnace by stacking broken bricks in a circle inside a old oil barrel and filling the gaps in each layer with mud. Yes normal mud and letting it dry. Our pipe is only 1 meter long and we use a blow torch to ignite the oil then it burns great. I love your simple methodology no fuss. Thanks for your videos and Hello from South Africa
Missed you. Got a farm soy exrusion plant running on your ideas (dryer, virgin oil degummer, pre extrusión heater, etc). Thank you again. Now working on your WI system on our tractors running 50% veggie oil.
+Roberto .Cavanagh That sounds awesome. It's great when people can put these ideas into practical applications that do work and save them money or time. I would really love to see some Vids of what you are doing. ATM I have the IP on my truck turned up so it's really giving me some power. I have upped the WI as well and the engine is showing every sign it's getting cleaned out more and more and keeps running better. WI is a very simple and beneficial thing for diesel engines especially those on veg. If you could do some vids and let me know that would be awesome.
Excellent Tutorial Video and also about the cheapest burner I have seen so far. I wish I had watched you Tube years ago, All the info I have collected for people like yourself has served me well. Thanx. Tom Ayr Scotland.
Welcome Back, OB!!!! I was getting worried about you.. Glad to see you were just screwing around in another direction.. Sounds like the compressor was running the entire time. I'm sure many will find a use for this, but I still like the old burners you have developed.. I think much less electrical power being used with the old.. Still lots of fun!!! Glad you posted up, buddy!! ;)
+Steve 1961P. Hi Steve, yeah, Things have been rough and I wasn't at all sure I'd do any more vids. Still not sure of how motivated I can stay but I'll see. I am still convinced the drip burners are easier, more practical and efficient than any spray or siphon design. The compressor was running the whole time and getting hot in the process. Some people seem dedicated to the Commercial spray burner nozzles which are a lot more expensive and complicated than this one and I'm buggered if I can see any advantage to them. Perhaps those that are dedicated to the spray burner design will find this a simpler and far cheaper way to go. Some people seem to thrive on over complication, expense and difficulty of operation. For me, the blown fuel/ drip type burners are a far more practical and versatile bit of gear but each to their own.
From all the oil burner desings i have tried, this is definitely the best, it's a very simple desing, it's adjustable and it's so easy to make. what i do have to say though is that the pipe or tube cannot have a taper or conical shape at the end. Thank you for sharing this simple desing, and showing us how it should be done!
Thanks for the kind words. It does always amaze me with the complication, expense and equipment people use to do a simple job when there are so much cheaper, simpler and easier alternatives. It's like so many people seem to think unless they go to a lot of trouble and expense something cannot possibly work.
I appreciate your straight and forward Miss on something and keeping it simple a lot of people make things complicated you have shown with simpleness Effectiveness can be achieved great video
Well Mate you stole my thunder near the end, I was going to remark (and I probably still am but who gives a toss) that if this was audio only I would swear it was a Buzz Bomb over London. Don't stop what you're doing Mate, It's brilliant.
Glad I finally found this channel. I've recently moved my shop to a bigger building and the temps are close to 0° here in northern Arkansas. Watched many videos but yours are the best and easier to understand
+Rodman Lyons When they have to put warning labels on Coffee cups. You know the stupid Disease is running out of control and something needs to be done. I bought a power tool the other day and the amount of safety notices in the thing was incredible. I had no intention of operating a power saw in a bathtub full of water and it never crossed my mind.... until I read the warning. The warnings must give the terminally stupid more Ideas than they were capable of coming up with on their own. ;0(
Lmao. You sir are correct. My drill had the same warnings. Even a gigantic red tag on the cord. WARNING!!!! Use of this power tool in wet areas could result in electric shock or death. My first thought was my neighbor standing in the shower hanging his new toilet paper roll. While the shower is on.
+Oil Burner ........................................and then you open the manual and it reads like War and Peace . Worse yet it tells you almost nothing you need to know yet the one part you can understand via the translator is all the safety bullshit like "don't stick your finger on the running blade" , UGhhhhh. If you do find something you want to know be extra careful doing it if it doesn't make sense. I just got a 30K tractor and the manual said to break it in you had to run it FULL POWER all the time for the first 50 hours. Yea I crap you not, Massey Ferguson made in Korea. Duhhhhh.
That's really got a nice spray pattern i wasn't quite expecting that. I think not relying on venturi to suck up the oil makes this much simpler than some spray burners. Looks very nice.
+builtrodewreckedit From what I have seen and read, I agree in that the oil being pressurised makes things easier. It seems a lot of people using the siphon nozzles in furnaces have to pressurise the fuel to get the flow and heat requirement they want out of them. They then need to add a blower as well to get the air needed for combustion. The spray pattern is very fine and mist like even on veg oil. It is almost surprising given the " nozzle" it just some copper tube squeezed down in a vice.
Take a round steal tub wrap copper capillary tubes around it with water running through it. Feed perlite heat sink barrels to keep your water hot and lay heart hose in the floor of your home to heat it. You could produce a steady electric current with heat transducers has well to run your home.
Love your work! I've built my foundry around your oil burner design. I use waste oil from autos. It's freaking awesome and hot as h-ll. I do use a bounce house blower instead of my compressor.
Thanks for the info. This is the best demonstration of the concept. Simple air fuel vaporized with ignition .in a chamber with exhaust flow.- and Adjustable .
Hi Oil Burner, I like the very simple principle the burner works on, especially the ultra clean burn. The only problem I see when used as a heater in the workshop is the carbon dioxide / Carbon Monoxide, both of which are the products of burning oil. These are heavier than air and can cause suffercation without any ventilation. An exhaust pipe would be required - to overcome the problem - and would need to be quite long to extract all the heat output via the walls of the exhaust pipe. Still a great idea and I will check just how much of the usable heat actually goes up the chimney so to speak. As a pensioner I need it to be ultra efficient as I like to get away from all the rubbish on TV during the winter months and do a bit of metal bashing in a warm workshop. Keep up the experiments and the inovation, It blows the mind ...literally. I must try an extra long exhaust pipe, at a guess I would think about 25-30 feet and see if the natural draft of that long a pipe would still give an efficient burn without having to use a compressor. Not sure of the oil flow rate as the air pressure into the tank would have to come from a point inside the exhaust pipe( venturi effect). It's worth thinking about. Regards to you and yours MoK
My first thought is... you've basically built a pressure pot style spray painter, with your burner nozzle instead of a paint sprayer gun. Other than it being a little too small, I could literally use a cheap paint sprayer I recently purchased at harbor freight instead of building the tank, and make a nozzle the way you did for the actual burner nozzle. Love the simplicity, looks awesome!
Using a spray gun is not near as simple as you think. Try it, I did and was very disappointed. The air/ Fuel ration is way off and you have to really butcher the gun to get it to work at all and then it's till not good. Plus yyou have a fuel takn that's way too small for any practical Purpose. Personally I don't like spray Burners at all and prefer the forced air style that you can get virtually infinite heat out of and dont need to run a noisy compressor,
@@glumpy10 That is a good point, thank you for the advice. Plus I eventually may want to use that sprayer to actually paint anyway. 😅 I'm thinking I need to learn how to weld so I can build a LPG tank gravity fed burner like you have (among a million other reasons). Your videos are awesome -- since watching your videos I have started trying to find a cheap bouncy house blower because I have a growing scrap metal + regular junk pile and love the idea of processing it myself to get top value/not pay to haul it to the dump. I am moving in a couple weeks and will finally have space to do stuff like this without the neighbors complaining. I like the idea of atomizing the oil spray for a more controlled burn but agree that compressed air is a big waste of electricity for something that can be done cheaper and easier with the gravity burner. Plus once it's heated up, the heat itself should vaporize the oil anyway. Your videos on the waste oil processing were very helpful as well, so thank you again and hope all is well down under 👍👍
Excellent way to describe a very efficient and economic solution for saving money in heating bills ! well done and keep the good work ongoing ... all the best mate and thank you the information !
+kbbacon I was looking at how the thing coated the fence with the spray demonstration and way thinking it would be really good to spray trailers and things with oil to stop them rusting. Probably also good for spraying plants with insecticide etc. If the Nozzle wasn't flattened it would be like the spray wand on a hose! Did your spray gun work for a burner? I tried it a few times over the years but could never get the guns to spray enough fuel.
just excelent idea. Good for every fuel. I do not need so long flame so I will bend a pipe around , weld it to close the end and drill a 10-20 or so holes at the top. That way I have a circular burner. I will test how it works.this week, reg Jack
Great work-nice and simple. Not sure how I’m going to convince the missus that we need one of these in the lounge room, not that poofy slow combustion wood heater. This looks like like much more fun.
As my company's elfen saftey rep if you know your machines they won't turn nasty all of a sudden. You'll know them inside out and they won't rip your insides out as I always say. Treat them with respect and know exactly what they do and you won't go wrong.
You are a genius,so simple to build from scrap yet so functional.I want to build something like this for heating my house,old engine oil will be used as fuel. I have central heating system with wather circulating trough cast iron radiators.Only one question can combustion chamber be shorter and wider I need it to fit in central heating wood/coal furnace.Thanks for great ideas You are only one who explained every detail about building, keep up the good work. Almost forgot any ideas about automated ignition of the burner(glowplug from diesel engine etc.)
+Zivojin Budimirovic Try it in the combustion chamber you have. You might need to put something in the flame path like a short metal tube to at as a " Glow plug" so there is a hot point to light the heavier oil. I haven't done anything with auto ignition but the best thought I have come up with so far is a small gas pilot light. Even a BBQ gas bottle should last weeks with a small flame. Thanks for the kind words, much appreciated. Nice to get a compliment instead of idiots whining about safety and the environment for a change.
I'm wondering if a continous arcing spark plug would ignite used motor oil and air mixture or just foul it out. I guess I'll find out. I have a woodburning stove made from a 55 gallon drum but I've grown too old and crippled to cut firewood. I'm thinking that this would work great in the barrel. I've got lots of old motor oil that is clean of any trash and debris, aside from the carbon and metalic particulates in used motor oil. I picked up about (60) 2gallon containers of used motor oil about three years ago. At the time I had no idea what I needed all that used oil for, I just knew I needed it. Thank you, you answered the question of why I needed the old oil and more impotantly solved my issue of heating my shop. By the way, if you have to tell someone not to look down the end that the flame exhausts from, you wasted your breath. They may heed your advise not to place their eye over a pipe belching fire like a military flamethrower but they'll find another way to either get hurt or burn down their home. It's called Natural Selection and the fact that there are so many blithering idiots surviving until adulthood these days is a direct consequence of mankind circumventing Natural Selection.
Definitely not good ... Think about your lungs and your families lungs. Plastic seal the windows, then use cheap throw blankets, and doors of the house. Use 3 small space heaters placed near cold spots on a thermostat. It will cost maybe $130 a month extra for heating the entire house
You built a simple version of a carburetor.......f@$!ing brillant! Reminds me of small engine class 25 yrs ago. We built something similar out of coke bottles and drinking straws. Love the vids i laugh my ass off everytime i watch. Hope the neighbors are well. Live free
I am impressed with the beauty of simplicity of your designs. Less is usually better I have learned over time. I just subscribed because of this. Happy new year to you and yours.
Thank You George, same to you and your family. I like simplicity. I think it's the hall mark of good design. I have seen many people go to a lot of expense and complication with these spray type burners and still have endless trouble. I would expect that on something made from junk but the fact is, I have never had any problem yet with this or other designs.
i have been experimenting with waste oil burners and for what its worth I have found that 8 to 15 psi gives best results depending on how fine a nozzle you create. Also the air supply from a compressor which is constant is best. To ignite the oil it must be pre heated to 80 degrees c or 175 F and it will then ignite with a standard burner ignitor.
Are you using a commercial nozzle or a DIY one like this? I find any preheating of the oil is useless because the millisecond it is atomised, it looses all it's heat to the air.
I have never seen anything like this before! thanks for the share and i do think you are correct about the sound is very close to that of an old aviation radial engine.
+Al Henning Hi Al, Stick with the one you have mate. For what you use it for it's much better. If you are having control issues let me know and I'll see if we can figure something out.
I'm gunna have a go at making one of these. I have 2 furnaces with the kwiky oil burner by David D that both work well, but yours is simpler again and doesn't require any machining. I might experiment a little and see if some form of nozzle works on the end. Will let you know how it goes. Thanks for the design though.
+Fairlanecustom300 I have looked at that design and a few others and am always floored by the complication in them. I looked at one the other day and I swear it must have 25 brass fittings on the thing and 3 valves and all sorts of other complexity and expense. At the end of the day, all they have to do is make fire so the simpler and cheaper that can be done, the better it is I say.
Thanks for the idéa, I have test it but with my own idea. I used copper pipe to create a spraygun so it create a vacuum that sucks the fuel in to the burner and it works just great. But oil burns not clean untill the burner is hot and diesel burns much cleaner. Thanks Oil burner
You are brilliant. I've duplicated several of your experiments part for part with identical results. Im an automotive technician with my own shop and alot of used oil. Ive thought about making a large version of this type but then I thought how small can this burner be made and still function? That is my current project. Love your videos!
+MR E Wow, thank you for the overly generous but much appreciated comments. it's good to hear when other people do things and they work out because I get some that don't seem to follow what I did and they have trouble. The principal will work in any size. you just have to keep it all proportional but there is a wide lattitude of what you can do anyway. Let me know how you go with your smaller burner.
i have a few things im interested in by the looks of it about 30 to 40 cm down seems to be the hot spot could you cut it off there and make a hotter flame or would it burn your pipe out quicker and if you put one of your big blowers in your fuel end would it create a hotter flame
Not sure if you will get this, But seeing you got a good hot flame, and your supplying air at the nozzle end from your compressor at that T. How would it work with your fuel pressurized as it is, Then remove the air pressure at the nozzle, (the T) but preheat the nozzle or fuel line from wrapping it around a heat source, will it still spray out eliminating the requirement for a compressor, except for the fuel tank. Which could be a hand pump,I' thinking of what happens when the power goes off. consider the set up similar to a tagger torch.
I don't think it would work at all. The fuel would carbonise if it got too hot and you'd be pumping like mad to compensate for the fuel level dropping at the rate it burns. One would be better pumping up an air tank and having that pressurise the fuel system though a regulator but then you still have the problem of atomising air.
@@glumpy10 If I recall we can take VO and run it through a copper tube or pipe, then wrap it around a wind supply tube from a fan forcing air into a furnace, (wrapping the pipe close to the furnace is fairly warm) that is to melt metal, And all that was used was a gravity feed for the oil, with a control nozzle for the supply of oil. If I recall correctly there was no need to force oil into the system under air pressure, and it got hot enough to melt metals? But just thought this might be of interest to try.
pressurizing to atomize the fuel burns hotter and cleaner than those drip feed systems. Many years ago I built a small furnace for my huge shop. I mainly burnt oil and coolant mixed and a 55 gal drum would last 4-5 months on 16 hr days.
+Pete Franklin One thing I have noticed, as well as being the simplest spray design I can find, it also seems to be one of the few if any that will light straight off on WVO. All the others I have seen are either using LPG for startup or are using diesel/ kero as the fuel.
I bet if it has a few bends in the pipe you'd get a more intense gasification, but it looks great, add big heat plate or box to that end it would give more heating surface area. It looks cool too.
The oil and air tank side is simple enough.my question is if you wanted more of a shop space heater how would you desing it so get plenty of radiant heat and minimal smoking?
+Edward Reid I was wondering that too. Wasn't aware the Aussies don't have them, thought they were everywhere. My workaround would be a compressor run by small diesel engine using waste veg oil for fuel.
Maybe I'm missing something? I see your atomizer T fitting and I see your tank plumbing but I don't see how the one connects to the latter. Assuming you run the fuel tank line to the lower branch of the atomizer, is your air-line from the tank running to the other horizontal branch? That would mean your compressor is charging the tank AND driving the atomizer. It would make sense, but just a one page sketch would be helpful. Very simple, unique, love it.
That's cool 👍 you should try a variant of this but instead of pressurizing the fuel oil itself, simply introduce it into the stream of air via a venturi, just a sharp angle "Y" tube tapped into the air line just before the orifice, the air moving through the "Y" will automatically draw the fuel into the air. The fire can stay continuously running and the tank will not need depressurization upon refuelling, will use less air and fuel and improve overall adjustability and efficiency. 👍
That is pretty much how all the rest of my many forced air Burners work. The fuel won't be drawn in and it won't atomise but it doesn't have to. The fuel is fed in by gravity or much better still , pumped or pressurised and the hot burner chamber phase changes the oil from a liquid to a gas so it can Burn. Have a look at all my other vids to see how it works and the huge amount of power you can get out the things.
Just out of curiosity do you know or could you get a temp reading on the flame, would love to know what temp it could get some steel to. i wonder in a confined space would it get the steel up to a yellow or white color.
This is a grest burner, however it uses lots of compressed air, yes? Thinking about a burner that uses a small amount of compressed air to spray oil and a blower for most of the air. Not sure how to keep the flows of air and oil in sync though.
+MrTechnophile You can see on one of the Later vids where I used a small blower to supplement the compressed air. I much prefer my blower style burners to these because they use no compressed air at all and are extremely powerful.
This is beginning to give me some ideas! I have a Hot Tub which uses quite a lit if firewood. I'm not getting any younger (just turned 60) and cutting all that wood is knackering me, and there aren't an awful lot of firewood trees left.... Now this should be able to do the job admirably! I have just a few questions... Will this run with a downward pointing tube, with the nozzle at the top and the flames coming out of the bottom? my boilr in the hot tub is just a big U shaped tube submerged low down in the water. The fire chamber is about a foot wide, horizontal, fed by a vertical lead in tube of the same size, welded together at a mitred corner. The chimney is at the opposite end of the fire tube, and about half the diameter, so if i could get me a fire tube like yours, only probably cast iron and with a 90 degree bend at the end, pointing the fire towards the chimney end, I think I can make this work. The other question was to clear up something I'm not quite clear about... the tube/hose carrying the fuel out of the 'tank' towards the nozzle.... this is with the fuel being pushed by air pressure?? Then the fuel is sort of atomised by the venturi effect when it comes up to more passing air at the TEE piece?? have I got that right?
The burner would run fine as you describe, downward firing. I have some vids from a couple of years or so back showing that with metal melts. You could make another fire tube from some large diamater exhaust pipe bunt in a U shaper or even coiled to give more surface area and heat transfer. Just leve about 500MM Out of the water so it is a hot section that will help put the heat into the oil it needs to change state from liquid to gas. This burner uses atomisation unlike all my other burners. Yes, the air pressure acts on the oil to force it to the nozzle that atomises it by shearing. I may have confused your other question with the burner type. This one would work with a jet on the end so higher pressures could be run without too much heat and get a bit better spray but it's NOT as important as everyone Imagines. Having the hear recirculation to change the state of the oil is however critical.
Thanks for the great vid mate. Could you use this for furnacing? I thought maybe a pipe welded to the square tube and an old hoover blowing into it for extra air, what do you think? Also, on your furnacing vid you don`t show us the burner setup, I can see though that it is gravity fed, how did you make the burner for that? Thanks again mate, top job.
Does the air valve pressurized and bleed off air at the same time? If I'm understanding this correctly the air goes in the tank and pushes petrol through the fuel line but simultaneously some air siphons off at the t valve and goes to the nozzel. I've never made one of these before but would like to make this design with some modifications on the nozzle end for heating up steel foe knife making
First of all the fuel is OIL not petrol and I highly reccomend you do not use petrol for any type back yard burner unless your life insurance is well paid up and you wish to leave you family a sizeable windfall. The air goes to the tank and pushes the oil with the air to the t Piece at the nozzle end to atomise it. People make WAY too much of the spraying or atomisation of the oil and can't seem to understand that the retained heat in the surroundings they are spraying it into is MUCH more important for a good, clean, reliable burn. The oil HAS to change from a liquid to a vapor to burn. Spraying helps that but it is NOT the reason it burns. Like all my other burners, you can have a solid stream of oil going into a hot chamber and it will burn perfect. Spraying is NOT the key to oil burning, HEAT is.
Hi Oil Burner, Would this setup work to heat water in a 200Litre drum? Or would it be too hot and shag the 200 litre drum? I was also thinking of using a large water pump pressure tank if the drum idea is a no go.
Just in case, I personally would use a one way check valve. just in case the fire gets back up in the jet. I love the project though, and may end up building one.
Oil only burns when mixed with an oxidizer (the oxygen in the air in this case). If you have a cup of oil and light it: only the surface and vaporized oil can burn, no air below the surface. Also it only burns so fast. If the fire somehow gets up in the nozzle, it'll just be blown back out. If it got to the oil feed tube, no air in there.
Sounds like you have set up a harmonic at about 40-50HZ similar to a pulse jet. This means the fuel has two chances to burn as well as igniting the incoming fuel air mixture. If you shorten the pipe it will resonate at a higher frequency. Have you tried shorter or longer pipes? Probably a dumb question but it would be cool to see it.
I've been wanting to build one for ages now. but I'm trying to work out a design that would work with no forced induction. I can get old truck brake drums at work and I was thinking of using three of these. to make a permanent fixture. just have to work out the details.
Probably just a space heater. I also have plans for a forge but that's a whole different route. PS your videos are always entertaining. Good to see an Aussie on here.
Thanks mate. I was actually testing a forge setup with the spray burner this afternoon. I have a modification to make and I'm confident it will work. I made a completely non powered heater some years ago but I have never got round to doing a vid of it. I'll get what I need and show how it's done soon.
these burners are awesome.. i know you dont like technical questions but i am curious as to how small of a pipe or tube you can use for the combustion tube. i am going to make a small oil burning forge and was thinking of using say 1/2 inch to 3/4 inch burner tube. with a 1/8 inch feeder/spray tube in the configuration you have here . do you think it wiil work? im gonna try it and let you know.. Thanks for the videos and ideas.
+roy moore Roy it's not that I don't like technical questions, I don't like stupid technical questions that I have explained 10 times already. There is a difference. :0) As for your very valid technical question, it's all a matter of proportion. The principal of why it works is the same ( like all my burners) regardless of size. You go smaller you'll get less air and oxygen and the amount of fuel you can burn will be smaller but it will work! Now obviously some people out there are, unlike myself, reasonably sane and may not want to make the biggest flames possible. Scaling the idea down is probably going to be a lot more practical for real world applications like yours. In a forge where there is so much heat once the thing is warmed up, you don't even need to spray the oil. You can just blow it in in the airstream like my other burners and it will work perfectly well. That said, the size and air consumption of a setup like you are talking about is likely to be so small it's probably not worth the trouble of going to a dual spray/ blow setup and you are better off using it the one way. Using this setup in a forge regardless of size will only make it work better. With what you are talking about, even burning 1-2 L of oil an hour is going to give you a lot of heat to work with and melt anything your refractory can stand! :0)
Nice.. how about a double 45 degree bend to a vertical chimney and you can avoid all the back flames and get a good suction effect from the vertical segment too
I only use ordinary bricks for that reason. they work fine but will get structurally weak from the heat. as they don't have to support anything, not a problem. I have found a mix of builders clay and sand on the face of them helps insulate and seal them as well.
This video has to be my favorite one of all, especially during the ignition and burning phase. The oil and air mix easily and then the square tubing facilitates the flame via a Venturi effect. I love the howling noise it makes too.
I was just looking at this setup yesterday thinking I should do another vid with it. Needs some new plastic Tubing which I don't know if I have or can get but I will look into doing another vid of it soon.
@@glumpy10 I would definitely watch another video with this setup if you get a chance.
Now this is something that you could use to make an oil burner heated deep fryer with, mount the cooker far enough away from the dragon-breath side and it would be able to work just fine.
Use old oil to heat new oil to cook in that will, over time, become used, which would then be burned to heat new oil... The circle of FIRE...
Glad your uploading videos again.
I've just built one of these. Not the exact same thing but same theory. Works like a charm. Within an hour of getting it finally assembled I was melting aluminum. I think I used about 4 gallons of used engine oil in an hour. It's not very demanding on my air compressor. I'm using 3/16" lines because that's what I had laying around. I think if I want to go hotter I have to go with bigger lines. Awesome build and awesome video. Thank you for sharing this.
Sitting here I was looking for a lighter for my pipe. I see that you've found a pipe for your lighter! Brilliant, mate. Great video!

huge thanks for uploading this video, been put off building my own spray type nozzle furnace for melting cast iron as all the ones i have seen use expensive fiddly bought in ones with loads of needle control valves for everything.i can see why you would want loads of control and the ease of buying in a valve but i couldn't see the simpler way to build one and now i can. many thanks again, keep up the good work !
+The Home Machinist You are welcome. Its very rewarding to know people are putting these ideas to work and benefiting from them. Really makes it all worth while. If you are able to video what you make, please let me know when you have. it's great to see what people do in action.
+Oil Burner HI oil burner, have built my nozzle, using gravity syphon feed, problem is it seems to be blowing out both nozzle and feed pipe. if i take nozzle out works great at syphoning but rubbish at atomising/ misting. i am using waste commercial veggie oil. playing with the pressure seems to do nothing. only thing i can thing of is using pressure feed for oil like in this video ?
Hey me and my friend used your instructions and made a oil burner in this style and it works great! We built our aluminium furnace by stacking broken bricks in a circle inside a old oil barrel and filling the gaps in each layer with mud. Yes normal mud and letting it dry.
Our pipe is only 1 meter long and we use a blow torch to ignite the oil then it burns great.
I love your simple methodology no fuss. Thanks for your videos and Hello from South Africa
Missed you. Got a farm soy exrusion plant running on your ideas (dryer, virgin oil degummer, pre extrusión heater, etc). Thank you again. Now working on your WI system on our tractors running 50% veggie oil.
+Roberto .Cavanagh That sounds awesome. It's great when people can put these ideas into practical applications that do work and save them money or time. I would really love to see some Vids of what you are doing.
ATM I have the IP on my truck turned up so it's really giving me some power. I have upped the WI as well and the engine is showing every sign it's getting cleaned out more and more and keeps running better. WI is a very simple and beneficial thing for diesel engines especially those on veg. If you could do some vids and let me know that would be awesome.
Excellent Tutorial Video and also about the cheapest burner I have seen so far. I wish I had watched you Tube years ago, All the info I have collected for people like yourself has served me well. Thanx. Tom Ayr Scotland.
Well I have built several variations ,but yours is by far the easiest , Cheers ,from Alberta Canada
Welcome Back, OB!!!! I was getting worried about you.. Glad to see you were just screwing around in another direction..
Sounds like the compressor was running the entire time. I'm sure many will find a use for this, but I still like the old burners you have developed.. I think much less electrical power being used with the old.. Still lots of fun!!! Glad you posted up, buddy!! ;)
+Steve 1961P. Hi Steve, yeah, Things have been rough and I wasn't at all sure I'd do any more vids. Still not sure of how motivated I can stay but I'll see.
I am still convinced the drip burners are easier, more practical and efficient than any spray or siphon design. The compressor was running the whole time and getting hot in the process. Some people seem dedicated to the Commercial spray burner nozzles which are a lot more expensive and complicated than this one and I'm buggered if I can see any advantage to them. Perhaps those that are dedicated to the spray burner design will find this a simpler and far cheaper way to go. Some people seem to thrive on over complication, expense and difficulty of operation.
For me, the blown fuel/ drip type burners are a far more practical and versatile bit of gear but each to their own.
From all the oil burner desings i have tried, this is definitely the best, it's a very simple desing, it's adjustable and it's so easy to make. what i do have to say though is that the pipe or tube cannot have a taper or conical shape at the end.
Thank you for sharing this simple desing, and showing us how it should be done!
Thanks for the kind words. It does always amaze me with the complication, expense and equipment people use to do a simple job when there are so much cheaper, simpler and easier alternatives. It's like so many people seem to think unless they go to a lot of trouble and expense something cannot possibly work.
I appreciate your straight and forward Miss on something and keeping it simple a lot of people make things complicated you have shown with simpleness Effectiveness can be achieved great video
“Click the like button whether you like it or not” love your attitude Aussie your great!
What about his great?
@@Mrkingjonny360 good catch. That was great😁☕
Well Mate you stole my thunder near the end, I was going to remark (and I probably still am but who gives a toss) that if this was audio only I would swear it was a Buzz Bomb over London. Don't stop what you're doing Mate, It's brilliant.
Glad I finally found this channel. I've recently moved my shop to a bigger building and the temps are close to 0° here in northern Arkansas. Watched many videos but yours are the best and easier to understand
I love your safety tips. I too am all for natural selection. Remove ALL warning labels.
+Rodman Lyons When they have to put warning labels on Coffee cups. You know the stupid Disease is running out of control and something needs to be done. I bought a power tool the other day and the amount of safety notices in the thing was incredible. I had no intention of operating a power saw in a bathtub full of water and it never crossed my mind.... until I read the warning. The warnings must give the terminally stupid more Ideas than they were capable of coming up with on their own. ;0(
Lmao. You sir are correct. My drill had the same warnings. Even a gigantic red tag on the cord. WARNING!!!! Use of this power tool in wet areas could result in electric shock or death. My first thought was my neighbor standing in the shower hanging his new toilet paper roll. While the shower is on.
+Oil Burner ........................................and then you open the manual and it reads like War and Peace . Worse yet it tells you almost nothing you need to know yet the one part you can understand via the translator is all the safety bullshit like "don't stick your finger on the running blade" , UGhhhhh. If you do find something you want to know be extra careful doing it if it doesn't make sense. I just got a 30K tractor and the manual said to break it in you had to run it FULL POWER all the time for the first 50 hours. Yea I crap you not, Massey Ferguson made in Korea. Duhhhhh.
I love your enthusiasm! I'll put my hubby right on building one of these since he always has jugs of waste oil sitting around!
I'm back in 23, and this is better than ever.
That's really got a nice spray pattern i wasn't quite expecting that. I think not relying on venturi to suck up the oil makes this much simpler than some spray burners. Looks very nice.
+builtrodewreckedit From what I have seen and read, I agree in that the oil being pressurised makes things easier. It seems a lot of people using the siphon nozzles in furnaces have to pressurise the fuel to get the flow and heat requirement they want out of them. They then need to add a blower as well to get the air needed for combustion.
The spray pattern is very fine and mist like even on veg oil. It is almost surprising given the " nozzle" it just some copper tube squeezed down in a vice.
I like that if the power to your compressor goes out, the pressure and fuel and flame will to. Convenient and safe.
Take a round steal tub wrap copper capillary tubes around it with water running through it. Feed perlite heat sink barrels to keep your water hot and lay heart hose in the floor of your home to heat it. You could produce a steady electric current with heat transducers has well to run your home.
It’s 7 years later and still think it’s very cool.
Love your work! I've built my foundry around your oil burner design. I use waste oil from autos. It's freaking awesome and hot as h-ll. I do use a bounce house blower instead of my compressor.
Thanks for the info. This is the best demonstration of the concept. Simple air fuel vaporized with ignition .in a chamber with exhaust flow.- and Adjustable .
Hi Oil Burner,
I like the very simple principle the burner works on, especially the ultra clean burn. The only problem I see when used as a heater in the workshop is the carbon dioxide / Carbon Monoxide, both of which are the products of burning oil. These are heavier than air and can cause suffercation without any ventilation. An exhaust pipe would be required - to overcome the problem - and would need to be quite long to extract all the heat output via the walls of the exhaust pipe. Still a great idea and I will check just how much of the usable heat actually goes up the chimney so to speak. As a pensioner I need it to be ultra efficient as I like to get away from all the rubbish on TV during the winter months and do a bit of metal bashing in a warm workshop. Keep up the experiments and the inovation, It blows the mind ...literally. I must try an extra long exhaust pipe, at a guess I would think about 25-30 feet and see if the natural draft of that long a pipe would still give an efficient burn without having to use a compressor. Not sure of the oil flow rate as the air pressure into the tank would have to come from a point inside the exhaust pipe( venturi effect). It's worth thinking about.
Regards to you and yours
MoK
Love this guys "SAFETY TIPS!"
My first thought is... you've basically built a pressure pot style spray painter, with your burner nozzle instead of a paint sprayer gun. Other than it being a little too small, I could literally use a cheap paint sprayer I recently purchased at harbor freight instead of building the tank, and make a nozzle the way you did for the actual burner nozzle. Love the simplicity, looks awesome!
Using a spray gun is not near as simple as you think. Try it, I did and was very disappointed. The air/ Fuel ration is way off and you have to really butcher the gun to get it to work at all and then it's till not good. Plus yyou have a fuel takn that's way too small for any practical Purpose.
Personally I don't like spray Burners at all and prefer the forced air style that you can get virtually infinite heat out of and dont need to run a noisy compressor,
@@glumpy10 That is a good point, thank you for the advice. Plus I eventually may want to use that sprayer to actually paint anyway. 😅 I'm thinking I need to learn how to weld so I can build a LPG tank gravity fed burner like you have (among a million other reasons). Your videos are awesome -- since watching your videos I have started trying to find a cheap bouncy house blower because I have a growing scrap metal + regular junk pile and love the idea of processing it myself to get top value/not pay to haul it to the dump. I am moving in a couple weeks and will finally have space to do stuff like this without the neighbors complaining. I like the idea of atomizing the oil spray for a more controlled burn but agree that compressed air is a big waste of electricity for something that can be done cheaper and easier with the gravity burner. Plus once it's heated up, the heat itself should vaporize the oil anyway. Your videos on the waste oil processing were very helpful as well, so thank you again and hope all is well down under 👍👍
For better results, try to move the nozzle a little bit inside the tube. This creates a much stronger draft and helps to stabilize the flame.
Excellent way to describe a very efficient and economic solution for saving money in heating bills ! well done and keep the good work ongoing ... all the best mate and thank you the information !
I have used a paint spray gun and it works just like that. You made a huge paint spray gun! Good job!
+kbbacon I was looking at how the thing coated the fence with the spray demonstration and way thinking it would be really good to spray trailers and things with oil to stop them rusting. Probably also good for spraying plants with insecticide etc. If the Nozzle wasn't flattened it would be like the spray wand on a hose!
Did your spray gun work for a burner? I tried it a few times over the years but could never get the guns to spray enough fuel.
It worked! I'll do a video. There is a trick, if I can get my stuff together.
neosomato hypergenesis It depends upon your air/fuel output. Can be small (10k btu) or as big as you can handle.
just excelent idea. Good for every fuel. I do not need so long flame so I will bend a pipe around , weld it to close the end and drill a 10-20 or so holes at the top. That way I have a circular burner. I will test how it works.this week, reg Jack
You come up with so cool oil burners. I think I will try this one. Thanks for posting!
+David Hoover Thank you for the kind words.
I love it mate! you are a legend!! I have lots of waste engine oil a old 45 gallon drum and loads of scrap metal. keep em coming you ripper!!
Great work-nice and simple. Not sure how I’m going to convince the missus that we need one of these in the lounge room, not that poofy slow combustion wood heater. This looks like like much more fun.
As my company's elfen saftey rep if you know your machines they won't turn nasty all of a sudden. You'll know them inside out and they won't rip your insides out as I always say. Treat them with respect and know exactly what they do and you won't go wrong.
You are a genius,so simple to build from scrap yet so functional.I want to build something like this for heating my house,old engine oil will be used as fuel.
I have central heating system with wather circulating trough cast iron radiators.Only one question can combustion
chamber be shorter and wider I need it to fit in central heating wood/coal furnace.Thanks for great ideas You are only one who explained every detail about building, keep up the good work.
Almost forgot any ideas about automated ignition of the burner(glowplug from diesel engine etc.)
+Zivojin Budimirovic Try it in the combustion chamber you have. You might need to put something in the flame path like a short metal tube to at as a " Glow plug" so there is a hot point to light the heavier oil.
I haven't done anything with auto ignition but the best thought I have come up with so far is a small gas pilot light. Even a BBQ gas bottle should last weeks with a small flame.
Thanks for the kind words, much appreciated. Nice to get a compliment instead of idiots whining about safety and the environment for a change.
Very clean burn, and very environmental friendly because it uses vegetable oil.
I'm wondering if a continous arcing spark plug would ignite used motor oil and air mixture or just foul it out. I guess I'll find out. I have a woodburning stove made from a 55 gallon drum but I've grown too old and crippled to cut firewood. I'm thinking that this would work great in the barrel. I've got lots of old motor oil that is clean of any trash and debris, aside from the carbon and metalic particulates in used motor oil. I picked up about (60) 2gallon containers of used motor oil about three years ago. At the time I had no idea what I needed all that used oil for, I just knew I needed it. Thank you, you answered the question of why I needed the old oil and more impotantly solved my issue of heating my shop.
By the way, if you have to tell someone not to look down the end that the flame exhausts from, you wasted your breath. They may heed your advise not to place their eye over a pipe belching fire like a military flamethrower but they'll find another way to either get hurt or burn down their home. It's called Natural Selection and the fact that there are so many blithering idiots surviving until adulthood these days is a direct consequence of mankind circumventing Natural Selection.
Definitely not good ... Think about your lungs and your families lungs. Plastic seal the windows, then use cheap throw blankets, and doors of the house. Use 3 small space heaters placed near cold spots on a thermostat. It will cost maybe $130 a month extra for heating the entire house
Hey i built one of your oil burner's and it works great
You built a simple version of a carburetor.......f@$!ing brillant! Reminds me of small engine class 25 yrs ago. We built something similar out of coke bottles and drinking straws. Love the vids i laugh my ass off everytime i watch. Hope the neighbors are well. Live free
Well said.....it's no pulse jet
I am impressed with the beauty of simplicity of your designs. Less is usually better I have learned over time. I just subscribed because of this. Happy new year to you and yours.
Thank You George, same to you and your family.
I like simplicity. I think it's the hall mark of good design. I have seen many people go to a lot of expense and complication with these spray type burners and still have endless trouble. I would expect that on something made from junk but the fact is, I have never had any problem yet with this or other designs.
5:40 I did click the like button even and there is nothing to unlike about this fantastic project. Keep up the good work.
Thank You!
You are welcome.
The minute that burner lite I thought of ww two buzz bombs , weird how it sounds so similar
I love the simple design and the huge orange flames!!
+David D Whats not to be loved about that! :0)
i have been experimenting with waste oil burners and for what its worth I have found that 8 to 15 psi gives best results depending on how fine a nozzle you create. Also the air supply from a compressor which is constant is best. To ignite the oil it must be pre heated to 80 degrees c or 175 F and it will then ignite with a standard burner ignitor.
Are you using a commercial nozzle or a DIY one like this?
I find any preheating of the oil is useless because the millisecond it is atomised, it looses all it's heat to the air.
I have never seen anything like this before! thanks for the share and i do think you are correct about the sound is very close to that of an old aviation radial engine.
It sounds like a pissed off bumble bee. Love it.
And a v 1 rocket
good to see you alive and well. safety tip of the day... do not eat beans and use the farts as pressured air. it will go in melt down.
and you'll be single in no time
My wife does not grant me a devorce. I see it as a challenge.
If she won't, just build a 3kw oil burner to get rid of the body - "forge your own freedom"!
hahahaha
Primitive-Effective-and Brutal...!Perfect!
great stuff. good to see you back, makes me want to finish my one. Still trying to put a second hole in my gas bottle!
Wow! Thanks David! Might have to rework that heater from last year. This looks much better, as to control. Hope you are having a great spring. Al
+Al Henning Hi Al, Stick with the one you have mate. For what you use it for it's much better. If you are having control issues let me know and I'll see if we can figure something out.
Buzz bombs yeah. *chuckles* My first thought when that fired up was, that's a simple pulse jet engine.
same lol
I'm gunna have a go at making one of these. I have 2 furnaces with the kwiky oil burner by David D that both work well, but yours is simpler again and doesn't require any machining. I might experiment a little and see if some form of nozzle works on the end. Will let you know how it goes. Thanks for the design though.
+Fairlanecustom300 I have looked at that design and a few others and am always floored by the complication in them. I looked at one the other day and I swear it must have 25 brass fittings on the thing and 3 valves and all sorts of other complexity and expense. At the end of the day, all they have to do is make fire so the simpler and cheaper that can be done, the better it is I say.
Thanks for uploading an useful topic to the world of you tubers. God bless you 😉👍🏻
Thanks for the idéa, I have test it but with my own idea. I used copper pipe to create a spraygun so it create a vacuum that sucks the fuel in to the burner and it works just great. But oil burns not clean untill the burner is hot and diesel burns much cleaner. Thanks Oil burner
+Erik Strandberg Be interesting to see what you have come up with if you could do a vid. Sounds like a great system!
+Oil Burner I can send you a video on the burner on Google+
You are brilliant. I've duplicated several of your experiments part for part with identical results. Im an automotive technician with my own shop and alot of used oil. Ive thought about making a large version of this type but then I thought how small can this burner be made and still function? That is my current project. Love your videos!
+MR E Wow, thank you for the overly generous but much appreciated comments. it's good to hear when other people do things and they work out because I get some that don't seem to follow what I did and they have trouble. The principal will work in any size. you just have to keep it all proportional but there is a wide lattitude of what you can do anyway.
Let me know how you go with your smaller burner.
multiple particles need to be able to fit thrugh!
i have a few things im interested in by the looks of it about 30 to 40 cm down seems to be the hot spot could you cut it off there and make a hotter flame or would it burn your pipe out quicker and if you put one of your big blowers in your fuel end would it create a hotter flame
Yea!!!!...havent seen your videos in a long time...your my favorite pyro
Thanks Mate! I hope to get back to it one day.
I love it how much more easy can you get. Love your videos keep them coming. Have a happy new year
I used to meddle with burning oils year ago. Must revisit it.
I like it! I need a person like you in my backyard!
And I need a backyard like that (my wife would kill me of course, but hey...)
Not sure if you will get this, But seeing you got a good hot flame, and your supplying air at the nozzle end from your compressor at that T.
How would it work with your fuel pressurized as it is, Then remove the air pressure at the nozzle, (the T) but preheat the nozzle or fuel line from wrapping it around a heat source, will it still spray out eliminating the requirement for a compressor, except for the fuel tank. Which could be a hand pump,I' thinking of what happens when the power goes off. consider the set up similar to a tagger torch.
I don't think it would work at all. The fuel would carbonise if it got too hot and you'd be pumping like mad to compensate for the fuel level dropping at the rate it burns.
One would be better pumping up an air tank and having that pressurise the fuel system though a regulator but then you still have the problem of atomising air.
@@glumpy10 If I recall we can take VO and run it through a copper tube or pipe, then wrap it around a wind supply tube from a fan forcing air into a furnace, (wrapping the pipe close to the furnace is fairly warm) that is to melt metal, And all that was used was a gravity feed for the oil, with a control nozzle for the supply of oil.
If I recall correctly there was no need to force oil into the system under air pressure, and it got hot enough to melt metals?
But just thought this might be of interest to try.
@@CMAenergy Sounds like it would work but is more like the blow air systems all my other burners use than this spray Nozzle design.
wow, this will be a great burner for a small pottery kiln.
How short could you make the ignition tube? To make it a hand held burner for weeds on fence lines
pressurizing to atomize the fuel burns hotter and cleaner than those drip feed systems. Many years ago I built a small furnace for my huge shop. I mainly burnt oil and coolant mixed and a 55 gal drum would last 4-5 months on 16 hr days.
Welcome back. Been missing my safety tips.
Me, I would weld some metal mesh to that baby so I can melt metal and cook dinner at the same time.
Chicken tighs grilled with burning oil mist, 7 out of 2 doctors recommend :D
Love the health a safety tip!
Im going to try this as seems the easiest version yet!
+Pete Franklin One thing I have noticed, as well as being the simplest spray design I can find, it also seems to be one of the few if any that will light straight off on WVO. All the others I have seen are either using LPG for startup or are using diesel/ kero as the fuel.
I bet if it has a few bends in the pipe you'd get a more intense gasification, but it looks great, add big heat plate or box to that end it would give more heating surface area. It looks cool too.
By pipe do you mean the square tube or the nozzle?
The oil and air tank side is simple enough.my question is if you wanted more of a shop space heater how would you desing it so get plenty of radiant heat and minimal smoking?
Surely the electricity you would use to make the compression would counteract the saving you would make on a traditional oil burner?
+Edward Reid Whats a traditional oil burner? If you mean the gun type that are in American home " Furnace's" we don't have them here in oz.
+Edward Reid
I was wondering that too. Wasn't aware the Aussies don't have them, thought they were everywhere. My workaround would be a compressor run by small diesel engine using waste veg oil for fuel.
I did comment the ww2 thing before you said it so I deleted it but what a demonstration....Cheers mate.
AWESOME EXAMPLE! thanks for post.. what happens if u lean out mixture too much?
+Scott Carter It will go out but if its warmed up and you fatten the mixture again it will generally light up again and you can re tune it.
thnx again
Maybe I'm missing something? I see your atomizer T fitting and I see your tank plumbing but I don't see how the one connects to the latter. Assuming you run the fuel tank line to the lower branch of the atomizer, is your air-line from the tank running to the other horizontal branch? That would mean your compressor is charging the tank AND driving the atomizer. It would make sense, but just a one page sketch would be helpful. Very simple, unique, love it.
+dean germeten Compressed air goes to tank which pressurises the fuel and sends it and compressed air to the burner head.
Is it possible to build a diy waste oil forge and or a waste oil foundry.
This seems interesting.... but what is it used for?
That's cool 👍 you should try a variant of this but instead of pressurizing the fuel oil itself, simply introduce it into the stream of air via a venturi, just a sharp angle "Y" tube tapped into the air line just before the orifice, the air moving through the "Y" will automatically draw the fuel into the air.
The fire can stay continuously running and the tank will not need depressurization upon refuelling, will use less air and fuel and improve overall adjustability and efficiency. 👍
That is pretty much how all the rest of my many forced air Burners work. The fuel won't be drawn in and it won't atomise but it doesn't have to. The fuel is fed in by gravity or much better still , pumped or pressurised and the hot burner chamber phase changes the oil from a liquid to a gas so it can Burn. Have a look at all my other vids to see how it works and the huge amount of power you can get out the things.
I clicked the like button as I was told.
+Zaappp !!! Thank You! Much appreciated.
I love Fish and Chips. Im really enjoying your video's.
+bmoraski I think I'll have to do a fish and chips cook up video. Maybe Donuts too!
Hell yeah !
Just out of curiosity do you know or could you get a temp reading on the flame, would love to know what temp it could get some steel to. i wonder in a confined space would it get the steel up to a yellow or white color.
Cheers Mate from John. I now have what I need to know to build my own furnace.
love it..
This is a grest burner, however it uses lots of compressed air, yes? Thinking about a burner that uses a small amount of compressed air to spray oil and a blower for most of the air. Not sure how to keep the flows of air and oil in sync though.
+MrTechnophile You can see on one of the Later vids where I used a small blower to supplement the compressed air. I much prefer my blower style burners to these because they use no compressed air at all and are extremely powerful.
Much like a torpedo heater
is there a chance for the flame to get into the nozzle and blow it up
Great teacher. Thanks for the show.
This is beginning to give me some ideas! I have a Hot Tub which uses quite a lit if firewood. I'm not getting any younger (just turned 60) and cutting all that wood is knackering me, and there aren't an awful lot of firewood trees left.... Now this should be able to do the job admirably! I have just a few questions... Will this run with a downward pointing tube, with the nozzle at the top and the flames coming out of the bottom? my boilr in the hot tub is just a big U shaped tube submerged low down in the water. The fire chamber is about a foot wide, horizontal, fed by a vertical lead in tube of the same size, welded together at a mitred corner. The chimney is at the opposite end of the fire tube, and about half the diameter, so if i could get me a fire tube like yours, only probably cast iron and with a 90 degree bend at the end, pointing the fire towards the chimney end, I think I can make this work. The other question was to clear up something I'm not quite clear about... the tube/hose carrying the fuel out of the 'tank' towards the nozzle.... this is with the fuel being pushed by air pressure?? Then the fuel is sort of atomised by the venturi effect when it comes up to more passing air at the TEE piece?? have I got that right?
The burner would run fine as you describe, downward firing. I have some vids from a couple of years or so back showing that with metal melts. You could make another fire tube from some large diamater exhaust pipe bunt in a U shaper or even coiled to give more surface area and heat transfer. Just leve about 500MM Out of the water so it is a hot section that will help put the heat into the oil it needs to change state from liquid to gas.
This burner uses atomisation unlike all my other burners. Yes, the air pressure acts on the oil to force it to the nozzle that atomises it by shearing. I may have confused your other question with the burner type. This one would work with a jet on the end so higher pressures could be run without too much heat and get a bit better spray but it's NOT as important as everyone Imagines. Having the hear recirculation to change the state of the oil is however critical.
Thanks for the great vid mate. Could you use this for furnacing? I thought maybe a pipe welded to the square tube and an old hoover blowing into it for extra air, what do you think? Also, on your furnacing vid you don`t show us the burner setup, I can see though that it is gravity fed, how did you make the burner for that? Thanks again mate, top job.
Does the air valve pressurized and bleed off air at the same time? If I'm understanding this correctly the air goes in the tank and pushes petrol through the fuel line but simultaneously some air siphons off at the t valve and goes to the nozzel. I've never made one of these before but would like to make this design with some modifications on the nozzle end for heating up steel foe knife making
First of all the fuel is OIL not petrol and I highly reccomend you do not use petrol for any type back yard burner unless your life insurance is well paid up and you wish to leave you family a sizeable windfall.
The air goes to the tank and pushes the oil with the air to the t Piece at the nozzle end to atomise it.
People make WAY too much of the spraying or atomisation of the oil and can't seem to understand that the retained heat in the surroundings they are spraying it into is MUCH more important for a good, clean, reliable burn.
The oil HAS to change from a liquid to a vapor to burn. Spraying helps that but it is NOT the reason it burns. Like all my other burners, you can have a solid stream of oil going into a hot chamber and it will burn perfect.
Spraying is NOT the key to oil burning, HEAT is.
Hi Oil Burner, Would this setup work to heat water in a 200Litre drum? Or would it be too hot and shag the 200 litre drum? I was also thinking of using a large water pump pressure tank if the drum idea is a no go.
Just in case, I personally would use a one way check valve. just in case the fire gets back up in the jet. I love the project though, and may end up building one.
+_Husky Can't light the oil, it is not flammable as a liquid, only a gas.
Oil only burns when mixed with an oxidizer (the oxygen in the air in this case). If you have a cup of oil and light it: only the surface and vaporized oil can burn, no air below the surface. Also it only burns so fast. If the fire somehow gets up in the nozzle, it'll just be blown back out. If it got to the oil feed tube, no air in there.
Looks + sounds like a pulse jet
+joohop it is a pulse jet
+emutiny I don't believe it falls into that category. These work more on the venturi principal.
+joohop
yes, the same soud of a V.1 Vergeltungswaffe
If resonation is a problem, have the burner tube inside another tube with THICK wadding (rockwool?) in between.
I thought the pulse jets had a valve ?
Sounds like you have set up a harmonic at about 40-50HZ similar to a pulse jet. This means the fuel has two chances to burn as well as igniting the incoming fuel air mixture. If you shorten the pipe it will resonate at a higher frequency. Have you tried shorter or longer pipes? Probably a dumb question but it would be cool to see it.
Whats the specs on your air compressor for this
I've been wanting to build one for ages now. but I'm trying to work out a design that would work with no forced induction. I can get old truck brake drums at work and I was thinking of using three of these. to make a permanent fixture. just have to work out the details.
+me217 Are you wanting to melt metal, heat water or make a space heater?
Probably just a space heater. I also have plans for a forge but that's a whole different route. PS your videos are always entertaining. Good to see an Aussie on here.
Thanks mate. I was actually testing a forge setup with the spray burner this afternoon. I have a modification to make and I'm confident it will work.
I made a completely non powered heater some years ago but I have never got round to doing a vid of it. I'll get what I need and show how it's done soon.
Cheers mate. Will keep my eye out for it. Have a good one.
That's a good job of tinkering !
these burners are awesome.. i know you dont like technical questions but i am curious as to how small of a pipe or tube you can use for the combustion tube. i am going to make a small oil burning forge and was thinking of using say 1/2 inch to 3/4 inch burner tube. with a 1/8 inch feeder/spray tube in the configuration you have here . do you think it wiil work? im gonna try it and let you know.. Thanks for the videos and ideas.
+roy moore Roy it's not that I don't like technical questions, I don't like stupid technical questions that I have explained 10 times already. There is a difference. :0)
As for your very valid technical question, it's all a matter of proportion. The principal of why it works is the same ( like all my burners) regardless of size. You go smaller you'll get less air and oxygen and the amount of fuel you can burn will be smaller but it will work!
Now obviously some people out there are, unlike myself, reasonably sane and may not want to make the biggest flames possible. Scaling the idea down is probably going to be a lot more practical for real world applications like yours. In a forge where there is so much heat once the thing is warmed up, you don't even need to spray the oil. You can just blow it in in the airstream like my other burners and it will work perfectly well.
That said, the size and air consumption of a setup like you are talking about is likely to be so small it's probably not worth the trouble of going to a dual spray/ blow setup and you are better off using it the one way.
Using this setup in a forge regardless of size will only make it work better. With what you are talking about, even burning 1-2 L of oil an hour is going to give you a lot of heat to work with and melt anything your refractory can stand! :0)
awesome mate thanks for the info.
the sound look like pulse jet. I love it.
I wonder how this would go with a blower attached on air intake end
Nice.. how about a double 45 degree bend to a vertical chimney and you can avoid all the back flames and get a good suction effect from the vertical segment too
can youn use ordinary bricks instead of fire brick which aew 9 dollars each in qld
I only use ordinary bricks for that reason. they work fine but will get structurally weak from the heat. as they don't have to support anything, not a problem. I have found a mix of builders clay and sand on the face of them helps insulate and seal them as well.
Can this melt metal(specifically brass)
Yes lead, aluminum, copper, brass, and iron, steel!!!!!!
