- I made some key changes to the air and fuel delivery. This burner will run on any waste oil. I did a lot of testing with different oils and had success with all of them. Thanks for watching, and don't forget to like, share, comment, and subscribe!
The burner has been installed for about 44 hours and shows no signs of build-up or slowing down! I can't thank you enough for watching and all of the comments! I hope you are having a great day! Subscribe now so you don't miss future videos!
Try using the output housing from a decent size centrifugal water pump for the air input. I used one to build a coal forge and it works awesome to create a cyclone effect. Alot of those pump housings have 1/4 inch ports around the outside that can be used for fuel supply.
@@randallslattman3119,I'll look at that as an option! Thank you!
@@karlsoffroad8609 I'll keep notifications on to hopefully see you run with that idea! Also if you dont have any ideas on it, do you have any connections to help with making waste oil infused manure pellets???
@@randallslattman3119 I've definitely got access to manure, but I don't have a pellet press. My buddy has one, I'll get with him and see what he has to say on this idea. Thanks
@@randallslattman3119 ,I'm going to check some junkyards, I looked up a centrifugal water pump and found out they're very expensive! 😆
so what i did on my custom boiler is I had two flow meters for the oil. one set real low that ran just to keep the flame going at all times and then the other I used a 12v selenoid valve hooked up so when my shop calls for heat it opens up and I get a nice size fire going
lol Karl, glad to see you were wearing your safety sandals . A man cab never be too safe , I get yelled at for not wearing socks.
Looks like a great design, fast start and no smoke.
Thank you! I'll see how it goes with a 24-hour burn,if it can do that, it should work for my application.
Try to use the output housing side from a centrifuge water pump! It's the same idea you had with the flap you welded back up, only perfectly designed for better flow.
I love the videos brother. One thing I’d like to see is like this burner with a timer on say, a gallon of oil and a little more focus on the drip/stream size. Nice work man and I’m glad I’m subscribed 🤙🤙
I will do that. I'll probably do a comparison between different burners and see which one is the most efficient. That seems to be what everyone wants to know! Thanks for watching, and I appreciate the kind words!
@@karlsoffroad8609 I’m currently trying to do “off grid” heating and I love all your designs it I am definitely interested and n which one is the best balance between good heat output and fuel efficiency. I e seen burners with big flames and they are not even running a stream but rather just a steady drip. I appreciate the response. Keep up the good work!!
The ole eyecrometer, I like that, I may have to use that term myself
Best tool in the shop! I never have to look for it either! 🤣
@@karlsoffroad8609 😂
great design ,
love it . built a jumbo version of your fireplace insert. hopefully test tomorrow but I have family with needs more necessary than mine . will see . best wishes to you
I'd love to see that in action! I'm glad you built one! Keep me posted on how it goes! Thank you!
Another way to get a blue flame might be to atomize the oil with high pressure such as a fuel injector instead of a drip, but probably not worth the expense especially with a diy burner. When the the sky is the limit on spending then you can make a purse out of a sows ear...or a waste oil burner into a rocket engine.
It's no good you can't put a cup on it to keep your tea warm. GEEEEZZZZ is that hot! ♨♨♨ Yeh I have a problem working out if blue is hotter, it's hot but you need to throttle the air down in the holes by making them smaller to get blue flames for some weird reason I found. The height of the pot also makes a huge difference. There must be a formula to work out so we can get blue flame as needed. Never seen a blue flame burner melt cans though, obviously you could but as to how good it is at it I dunno? The main advantage of blue flame is you get very little soot in a small system like mine but yellow is terrible for soot using a 4 inch pipe for exhaust. The burner you have hear will work even better and hotter under your boiler especially if you put a shield up to protect it from wind if its outside. Mind you if your blasting so much air into it you won't get any build up of soot to speak of I expect. I put a lid on mine with a cutout for the exhaust to escape from, this contained the heat within the pot which radiates out to the propane bottle it's in so the heat radiates out sideways more which is what my needs are and it was only when I put the lid on I manage to get blue flame, except the one burner but that is quite tall and has a wider diameter and that thing will burn with no visible flames! All in all you have made a fantastic burner, I think you underestimate yourself a little bit too much cus the results you come up with are fantastic!
Thank you! I just finished installing it in my outdoor boiler, so I'll know much more by morning. It's got the water temp rising just like the old burner I was using, but I have it set way lower on the oil setting. I really think this will do the job with about half the oil I was using per day. I will definitely be watching it like a hawk to make sure I don't have any issues. I'll post a video of the installation as well.
I would like to see the follow up video having it installed in your boiler.@@karlsoffroad8609
Give us a version of sound of silence on the end of one of your videos,who knows might make you famous
I'll have to work on that! Thanks for the suggestion! I guess you never know what will happen!
would love to see how this might work with NO forced combustion air fan. Wondering with your heated air set up, if this will create a draft that self feeds the cumbustion air. Maybe one test wih no forced air at any time from cold start up, to running good.....AND- another test of use forced air to get it going and hot...... THEN... remove fan and use only draft to suck combustion air in.
I'll give that a try! Thanks for the suggestion. I'll probably have to change the burn nozzle. I don't think it would be able to pull on its own through the tiny holes. We'll see! Thanks for watching!
@@karlsoffroad8609 either way,,, w/blower or w/out if you can take pre existing holes and angle them so they all point at similar angle so air coming out creates a spin... this will increase atomization of oil for better combustion and might reduce hot spot wear on burn chamber walls.
I'm watching this again with keen interest. I don't understand the air supply arrangement, if the inner pipe and outer pipe have a space between them, you could do away with the central pipe with holes in. You could put the holes in the inner pipe, have the air supply as it is so the air would enter from the sides instead of the tube. I made a smaller version of a similar design using baby formula containers so it would be flimsy and not last long becaaaaaause it burns mega hot! That hot I abandoned the idea! Not because it was unsafe or anything like that but it would destroy the burn chamber in no time, however your big rig would easily withstand it. You obviously can't unweld the rig you have made now but if you could replicate it again but put 3 rows of 1.5mm holes around the walls of the inner pipe you will probably need your welding mask to see the flames they will be that bright, blue even depending on how much air you give it. Mayb3e 2-3mm holes but start small then go bigger if needed. I would not weld the inner pipe before testing though as you may need to adjust the size of the holes, once your happy weld it all up and you have a monster system!
I thought about doing that, but I wanted to be able to change nozzle designs easily, and I have had great luck with delivering the oil to the bottom of the burn chamber. I will definitely build one the other way and see what happens.
I do like the design you have and as you say you can change the nozzles at will if so desired and you will probably get the same results, so maybe not even worth trying if you are happy the way the burner works and as you say rightly you can always change the nozzle but not the holes in the inner pot. I would advise only do it if you simply want to experiment and are curious and have the materials available. The burner you have should work great anyway. :)@@karlsoffroad8609
Just clarifying what you did.........
1. the bottom is an "air pot" / heat exchanger that is surrounding burn chamber and sealed from the burn chamber
2. Air fed into "air pot " gets heated via hot, burn chamber walls..
3. heated air consequently fed into burn chamber
4. oil feed is embedded into the hot air feed into burn chamber and its tube end is just below of end of air tube.
5. oil feed gets heated by hot air path created by sequence of things in 1,2 ,3 above.
are their any mods to end of oil feed tube.....or is it open
@coachgeo Yes, to all of the above. I have a merchant coupling on the end of the oil feed line that rests on the bottom of the burn chamber. I cut four slots about 3/4 of an inch long to let the oil flow out. I'm doing a 24-hour burn right now, and I will decide if that is going to stay on after I complete my testing. So far, it's running without any issues. I have it in my outdoor boiler heating 500 gallons at 30 gallons/min. Working exactly like I hoped. Time will tell if I cured my problem of burn chamber meltdown. I will be doing a video on the whole setup soon. Anything else, I'll be happy to answer! Thanks for watching!
I'm hoping your new design will work long term for you. You have been testing a lot of different designs.
I've been running the same design for the last two years. I'm hoping this one will keep the burn chamber from burning through. I get a few months of burning, and then I have to build a new burn chamber. It's not a huge deal, but I would rather not!
I get it. Not hard to do but you would rather just be one and done!@@karlsoffroad8609
Gonns go to first now
Appreciate your hard work!
Took me a minute to figure out what you're doing there. Looks like you've created a manifold down towards the base of your burn chamber. The air goes into the manifold. Pre heats in the manifold and then enters your fuel nozzle...is that right?
Yes,this was the burner from the last video with the ideas I had after I struggled to get it to light. I installed it in my outdoor boiler and will have some better information on longevity and reliability soon! Thank you!
People that scour youtube trying to play osha are way weirder than us rockin safty sandals in our garages.
What about hanging a tin bucket of dry sand above it
I store heat with hot water and use it to heat my shop and home. I've never messed with sand batteries yet! Thanks for watching and your suggestion!
Do you have a video how you built the burner
Yes,it's the previous video.
I think the blue flame burns cleaner. But you’re going to be burning outside and that is not as big a deal.
Of course the blue flame burns clean .... Because it's lean, and a lean burn is great , except lean is low heat, and #2 u can't sustain a blue flame w waste motor oil ...but u can achieve it for a short time after a rich burn when u get the burn chamber superheated and then lean it out ...yea ull get a blue flame until everything cools down n then it'll go out ....
Burners can be "efficient" burning hot with a lot of oil. The efficiency level has nothing to do with the volume of oil, really. Small or large burners can be inefficient if there's wasted fuel or gas going up the chimney that doesn't get burned. Something that's say 80% efficient (big or small) is basically blowing 20 cents on the dollar up the chimney. How many BTUs can you extract over time, given a certain quantity of fuel with a known BTU per pound, gallon, square foot, whatever is the actual measure of efficiency. If you need a lot of heat, you're going to need a lot of oil. No getting around that regardless. I know what you were trying to say though, and I think most other people do to. Not baggin' on ya, just making a point.
I was just referring to the question of, how much oil does it use? I try to explain that it depends on how much heat you need. I'm glad someone understands! Thank you!
Impossible for cooking😅
