Winterized Alcohol Stove

Postby Ordin Aryguy » Thu Mar 06, 2008 11:06 pm

First post here... Pretty cool place!

FWIW, I really like soda can stoves. They're cheap, incredibly reliable, and light. However, since moving to a locale well above the Mason-Dixon Line, I've come to realize that alcohol tends to want to argue a bit about lighting when the mercury is low in the bulb. So, this is my answer to that...

Soda can stoves need to get warm enough for the alcohol to vaporize before they'll change over to "jet burners." Considering that aluminum is a tremendous conductor of heat, low temperatures tend to keep the stove from changing over to jet-mode. All that'll burn is the fuel in the center of the stove, and even that's a beast to get lit initially.

When it's cold out we wrap ourselves in insulation. "Why not wrap the stove in it, too?", I thought...

Two weekends ago a bunch of those nutty people I hang out with and myself went camping. The temps were well below zero, -8F one morning. This stove heated water for coffee, oatmeal, noodle lunches and melted a heap of snow with ne'er an argument. It worked absolutely flawlessly.

One little thing I did learn over that weekend, quite by accident, is to spill a small amount of alcohol into the insulation and light it, too. This really gets the fuel in the stove vaporizing quick with heat sources in both the core of the stove and around its' perimeter.

A wick of some sort definitely solves cold weather problems.

Hi Ordin,

Great idea, what does your stove weigh.

I like this site too.

Not really sure of its' weight, Tony. More than a few feathers, but far less the MSR's that my friends carry. ;)

Best part of building the insulating section is that it was a good reason to buy a couple "oil can" sized beers.

Hello and Welcome Ordin!

I like Your Idea of using the Fosters cans to insulate and prime the Pepsi can stove. :)
I have a Fosters can stove that should work like that too. I'll try it. That way I'll have a back up
stove also. :) Thanks for sharing Your idea. The Fosters can adds a lot of stabality too, because of
it's width. It also helps to keep Your fuel bottle in Your shirt pocket, to keep it warmer. :)

Cheers!

:D Hi Ordin, welcome !!!!!

Once you passed the Mason Dixon Line you kept on goin and goin and goin till you reached the Canadian border(International Falls MN, coldest spot in the U.S. :D -8 is brutal!!!!

I like the height of your stove. I looks on the short side. I think that's good. The closer you get the fuel to the rim of the burner the better. The less distance the heat has to travel to get to the fuel, the faster the fuel will vaporize and pressurize in the chamber to push the vapors out the jets and so on.

Next time anyone makes a pop can stove make it as short an you can. Make it so that max fuel capacity will be 3/4 oz (20ml) of fuel. Just enough to boil 2 cups. Make it so the diameter of the inside hole is as large as you can get it. The more lineal inches of rim surface being touched by the flames the better.

The sooner the better so you can test it in frigid temps without an insulated shell or primer pan. We have another cold snap coming from canada(thanks Darin and SamH) Going down to -0- here tonight.

I've used an open top side burner pepsi type stove made from V8 cans in +8 deg. F weather before.
It worked fine. No external primer pans, and the alcohol was cold too. Maybe it worked because of the small size?

Cheers!

P.S. That stove holds 1 oz. of alcohol
