Alcohol Stove Turbocharger

I've been fooling around with alcohol stoves(when I should be finishing my tent....sorry folks) Anyways,I ran across a guy that put a tea candle underneath his LOW PRESSURE!!!! alcohol stove......WOW!!! It cut the boiling times for my stove from 10-12 minutes for 2 cups of water down to less than 5 minutes!

My stove is a low pressure stove,it looks like swiss cheese.



I don't think this is a wise idea on a high pressure type stove,at least not standing anywhere near it

So if you feel like fooling around some,give it a whirl.I won't be using the idea myself,but if your in a big hurry to boil water.......

Again,I WOULD NOT EVEN ATTEMPT THIS WITH A HIGH PRESSURE TYPE STOVE!!!!! I'm pretty sure bad things will happen.I don't think it will let the extra gasses out fast enough,so that means you are making a bomb pretty much.

DO NOT TRY THIS ANYWHERE IN YOUR HOME OR GARAGE OR NEAR STUFF THAT WILL CATCH ON FIRE!!!!! My little stove put out some SERIOUS FLAMES!!!!! You might be able to forge a knife on it......

I tried to take some pictures of it but I'm not good enough with a camera to take them,sorry.I could probably make a camera,but I'm not so good at using one.

I find my boil times are typically around 5 minutes for 16 ounces of water no matter which design I use. I've been having a kick trying different designs. I've become partial to my stove made out of a hair mousse can. The cat can stove is a great design which is simple to make for those of you wanting to make your own but keep it simple.

PS - A long while ago, I tried the candle under a penny stove design and had flames shooting up about 4 feet. It ran out of fuel after approximately 2 minutes. So don't try it with a penny stove, but it does help with other designs.

PPS: Looking forward to seeing your finished tent Booger1!

I made this type of stove on purpose,I didn't like the fast cooking times of other stoves myself,but it sure made a huge difference in flame size.

Understandable. My stove is only really good for boiling water.

Trangia alcohol stoves can be speeded up by using their winter adapter that warms and accelerates the gasification of the alcohol. The 50 year old version I have is merely a thin brass plate with a shallow area where a wicking material absorbs the preheating alcohol and clips under the burner. It has worked well these many years. I have yet to time the boiling time. I am never in that much of a hurry.

Now, the question is, what does it do to your fuel efficiency?

In warmer climates, I've found that the Trangia burner can self-generate so much heat that it starts to chug away really hard, so much so its heat output can become uncontrollable and flames lick up around the pot.

I tried baking a loaf of soda bread a couple of time by putting the dough in a pot, and covering with a lid. I had to keep a very close watch as the flame continued to grow, despite the simmer ring being fitted, until it was a virtual fireball. And it can be quite difficult to extinguish once it gets to that point.

That's a time for extreme caution.

Obviously, the high ambient temperatures had a role in helping to vapourise the alcohol.

For cycle touring I cook a wider variety of foods than backpacking and can afford the additional weight of a larger cook pot. I still don't slow cook or simmer anything. Bring to boil and transfer whole pot into a well insulated pot cozy. Anything that would normally need about 20 minutes to cook will do just fine with this system. I carry one of those insulated shopping bags and buy groceries whenever I find a store along the way. One bag of frozen veggies, or meat will keep whatever I buy fresh till dinner in that bag. (the frozen food bag being the ice for everything else)
