Trangia DIY Stove V2.0 - Boil Test 2

In this video I re-test NCHiker1970's suggestion for a stove/pot stand but also using a windscreen to see if using one makes much difference.
I believe that using a windscreen in the field would make for a big difference in boiling time but using one on my work bench doesn't make much of a difference because there is no wind ( I know, except for what I make while talking. LOL). In this case the wind screen only shaved about 23 seconds off the time to boil time. Oh well, at least you get to see why I don't use a wind screen in most of my tests on my work bench.
Thanks again NCHiker1970.

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.

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

@0900pp the heat reflex to the stove make the fuel burn more and not balance with air.

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 ?

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.

[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.

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

[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.

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.
