I tried something interesting. I put vegetable oil in my stove, about a half ounce I guess. Then filled the rest of my stove with yellow heet for a single burn time test. I went from 24 minutes for a full stove burn with heet only to 44 minutes with the combination heet and vegetable oil. And it burned hot the whole time without soot. Very interesting.
Problem 1. The felt is blocking the airflow/gasflow to the gap around the bottom of the innerwall. Problem 2. The alcohol can't boil to produce gas to go up the blocked gap anyway as it's just being "wicked" to the top of the pad and being burnt there. Like you said, you may as well put the felt in an empty tin.
the question to be answered is how long does saturation need for it to occur. i cult my 1/4 felt into 3 circles the size of the opening. put the 3 layers into the burner. added 45 ml. fuel. capt the stove for 20 hrs to get wick saturation. got a burn time of 15 minutes, at a nice blue flame. did bloom inside 30 secs.
I think the carbon felt soaked up all the alcohol. Nothing went to the double wall as alcohol needs to go all the way down and seep through the bottom hole. You need to fill it up totally and slowly to saturate the felt and then let it seep trough to the double wall. Try using steel wool instead of carbon felt.
Would it work better is carbon felt was cut only as hight as the normal fuel line...so heat of normal area would happen at top of felt line ??? Looks like the felt was taking heat above the bloom line
It appears that the carbon felt sucked up all of the alcohol and it is also insulating the stove and preventing the alcohol from boiling and pressurizing.
If You were heating a can of soup w/o scorching it in the can , I think its " A OK " ! If You want to boil water , take the c/f out ( 2 stoves n 1 ) ! Might say it's multitasking !!
You might consider an open flame style burner, like a candle tin or cut the bottom off a small soda can. They have low heat output, very high fuel efficiency, and very long burn time. Perfect for baking. I've made some that burn over 20 minutes on a single ounce of fuel.
I preheated my trangia with some spilled fuel on the ring below the screw on cap. it appeared that the felt was insulating the stove from the burning fuel which is the stated purpose that the material was sold for in the first place. maybe swtiching to a fiberglass material would accomplish your test goal
I just watched Waw Hiker's video. His didn't bloom at all, he was simply burning from the center. @Catskillmountaingirl- Maybe try buying the sweetish army (full size) trangia that holds more fuel than the Mini trangia.
Interesting that it had such a hard time to bloom. I'm trying out different shrouds that accelerate air before meeting the jets for better fuel/air mixing, that cuts out the yellow part of flame that tends to create soot(lack of oxygen). You can see parts of effect by opening up simmer ring to max, and hold it still 1/8 - 1/4 inch above triangia burner. While the burn is better, so far it seems to make a hot spot instead of distribute flames more sideways.
just watched wawhiker's video he never had the jets ignite. wawhiker's just basically made a chafing dishes out of his trangia stove. but no jet action.
One great way to turn a Trangia into an pot warming alcohol burner and to destroy the main idea of using a Trangia. If you do not mind I will continue to use my Trangias in the manner they were designed for and even the simmering ring. If I open the top of the simmering ring to about 1/4 inch it works really well for it's intended purpose.
It would be interesting to see a boil/burn time test done between a normal Trangia and a carbon felt Trangia. That looked like the carbon felt worked as it should, even if the stove did not.
Hi ,do you think I should get a Trangia as an emergency stove , I have had 3 power cuts since I have moved in to a new block flats, and have had to go with out tea/coffee the night when I got home late from work, due to the engineers working on the power lines in the road, and can I use the Trangia inside? Thank you.
I think it is a bust. maybe as a slow cooker insert but the cf kills the ability of the trangia to function as designed. maybe carry a strip I of cf for when you want a long simmer time but no boil. maybe for baking.
man what you have to do just make the filter lower litil bbet so the flame heets the nick of the stove and heet the fule to start come of the jets thanks 4 tring
boil test please .but like you i do not think this is good for the trangia way of burning .but still would like to see a boil test and a burn out on an once of fuel
p.s how are you doing . is all well you seem a bit moody like something is wrong hope not but if so go out side and stare at the stars it always helps me i feel just like an ant .small
i tghink all this proves is that you can make a Trangia stove work worse! This is a downgrade in my eyes not an upgrade by any stretch of the imagination. Nice try, no cigar! Lol. If it ain't broke don't fix it.
You need 2 cm of loosely packed steel wool in the bottom, this lets the fluid up the side walls and into the jets. Then 1 cm of carbon fibre ontop

Have you tried using perlite instead of the felt? I would like to know if it would block the air vents. Thanks
Darn Hiram I'm watching reruns, oh the sight of watching water boil or ethanol flames.

I think the felt is wicking the fuel and keeping it in the center chamber, it has to fill the outside chamber for the jets to fire.
never mind, I just seen that you and others have already addressed that.
Try cutting down the width of the felt doesn't come to the edge. I am going to try it
with the felt 3/8" shorter. See if that makes a difference.

Adding the carbon felt slightly below the jets should allow the jets to blossom.
Nah.

I think it's a good idea but the felt is too tall.

Hiram it appears you have your carbon felt to deep, reduce the depth of the felt and bloom works and felt works too
Shame after all that effort and you didn't put a clock on how long it burnt compared to a normal Trangia. Still a great vid. Thanks.
If I recall correctly, Wahiker had to fully fuel the stove, to the top, before it bloomed.
You have the carbon felt all the way to the top have it halfway then it will heat up much quicker

Maybe the felt does make it work like a candle effect and not allowing for the jets to work.
Note to self; save the carbon felt for the tuna cans.

The trangia will be more useful with carbon felt in the winter time. :)

Thank you.
realize you need to have adequate ventilation if you use any flame indoors. I would get a cartridge stove.
Where do you get carbon felt at Hiram
I think it is a bust. maybe as a slow cooker insert but the cf kills the ability of the trangia to function as designed. maybe carry a strip I
of cf for when you want a long simmer time but no boil. maybe for baking.
I think the carbon felt is sitting too high within the stove.
how about lowering the felt so the flame hits the inside of the stove?
Would it bloom if the primer ring was used?
Even failed ideas are helpful
Don't make the felt so tall. You're preventing the capillaries from heating up.

Half a teaspoon of nutmeg every day. Takes about 10 days for it to work.
I think she would be Miles Ahead in her Endeavor if she would simply use a simmering ring
Hiram: cut the carbon felt about 1/2" below the top then it will bloom
Try ceramic felt.
Carbon to high, blocking the jet holes, looks like
