Trangia DIY Stove V2.0 - Boil Test 2

what is the first song

[gettinold2]

Just a couple of things...you had the pot on the burner for 20 seconds before you reset the timer. This means that there was only 3 seconds difference. The other this is, if you are useing a pot stand, there is no reason to let the stove bloom. Get the pot on the stand right away and use the early flame to your advantage by saving fuel. Thanks for doing these videos!

why the flames burn red , not blue ?

[cobalt120]

If you look at rocket stoves (wood as fuel). You can make a pot skirt.

It looks a little like your wind screen.

However since liquid fuel stoves, especially alcohol work a little differently.

The pot skirt needs to be adjusted to the pot with an even spacing on all sides, and the right height at the top to allow proper heat transfer.

At the moment your wind screen might end up acting like a heat sink and drawing heat away.

[cobalt120]

Try layering your wind screen with insulation .

Aluminum/fiberglass insulation/ Aluminum.

Once the insulation absorbs some heat it becomes saturated and reflects heat even more, and keeps the outer colder surface from drawing heat from the pot.

thats a nice one

Sweet vid that's crazy

Have you ever set the pot on the surface of the trangia to pressurize it so that it jets faster? Just curious, not looking for a whole video about it.

[hiramcook]

I never tried that. Not sure how much clearance there would be for the jets. Maybe an 1/8 to a 1/4 inch.

[BrokenAeroVT]

What do you think, is it at least worth giving it a whirl off video just to see if it works?

[BrokenAeroVT]

Revise that request, Hiram. Sitting a pot on the Trangia quenches the flame.

The solution to that problem is to make a cylindrical tube stand that fits tightly in the Trangia throat. The stand will act as a heat transfer mechanism raising the pressure inside the burner when a pot is set on it. It will also solve your search for a light weight pot stand.

I would like to see some investigation into this as well hiram.

I had thoughts along the same lines. My stove is a double-wall "budlight bottle" stove which works best when you set the pot on top of the stove. I don't really get the point of jetting a stove when the top remains open but they've been using Trangias for many years so there must be something to it...

[BrokenAeroVT]

The weight of the fuel in the center of the stove presses down against the fuel trying to rise because of the pressure in the outer wall, thus pressure is maintained in the wall.

[shad0h027]

True, but I think you miss my point. When I put a pot on my stove the jets burn but JUST the jets. With the Trangia you also have the center burning (not pressurized, not controlled) although it's much smaller than the center of my stove, so maybe it's ok. My stove would burn alcohol really fast without a pot on top.

[BrokenAeroVT]

The jets are near the top so a lid can contain fuel. Without the throat open, there is no substantial heat driving the vaporization. The stove becomes too weak to stay lit when a pot of cold water sits on it. Leaving it open, you get an extra 448w of power at the throat. That is sufficent to keep the stove lit and driven to about 640w.

By heating a larger area above the jets, a sideburner drives the vaporization at a much faster rate, yielding 997w, but now you can't store fuel in the burner.

[shad0h027]

Very true, I can't do that. I'm ok with it :) One of these days I should post a video on my cook kit. Nothing special-a fairly short budlight bottle, MSI soloist pot, aluminum flashing windscreen.

I haven't gotten tired of watching stove videos yet!

Sometimes a few seconds can make a difference. Thanks for doing this one for me Hiram. Look forward to the next test. Always enjoy your videos. Keep up the great work!

[DrunknShooter]

Another good one, thanks.
