Introduction: Alcohol Stove Burner

Picture of Alcohol Stove Burner

Ok, I'm sure most of us have played with the ubiquitous alcohol camping
stove. Not the most efficient means of cooking if the alcohol is just sitting there. I've found a way to get it to pressurize and cook as well as profane or natural gas.

Items you'll need:

Chaffing lamp with a screw-on cap (not the flat, these are ineffective in this project)

Needle nosed pliers

4 Penny nails

Cotton postal twine

91% Isoproply alcohol, HEET in the yellow bottle or just denatured alcohol.

Step 1: Step 1: the Container

Step 1:

These chaffing lamps that can be found at dollar tree called Fancy Heat use a wick and methanol. Once the methanol is used up, they're just empty cans.

When removing the wick head, use needle nosed pliers, stick one prong into the hole on the single piece cap, close and pull the head off. Don't close around the threaded part or you'll ruin the part of the head that needs to stay sealed during burning.

Step 2: Step 2: Nailing the Lip

Hammer three pin sized holes into the raised lip surrounding the cap head using one of the penny nails.

Then make three larger holes next to those to insert a cotton wick and penny nails into. The wick is meant to absorb the cotton and the nails are meant to 1. be used as a heat sink to help boil the alcohol and 2. act as a seal against most of the alcohol vapors, giving just one exit for each jet of alcohol vapor.

Step 3: Step 3: Let's Light This Candle!

Fill the canister to the bottom of the neck of the cap head with your choice of alcohol and screw the cap back on.

Let the alcohol absorb into the wicks for a few moments. Give the burner a test run by igniting all three wicks.

Step 4: Step 4: Cook Something.

I make sure that each cooking session the can is 90% full. This is about
6 oz of 91% isopropyl and 99% ethanol (IE; HEET in the yellow bottle) Non-continuous cook time is six hours on six oz, or 3.5 continuous hours on a full can. This is due to the burn rate in pre-warmed alcohol that is at vapor point vs. cold alcohol which still needs to reach vapor point (86f)

You can see the progression of the output of the burner within minutes.

Heh heh.... Fire....

Step 7: Three Minutes After Setting the Pot Down to Boil.

My aluminum cookware is having a hard time with this because the flames
are too hot and are slowly boiling away at the aluminum. Stainless and cast hold up just fine. To extinguish, just blow out or if you don't have the lung capacity, a spray bottle with water and a couple of squirts.

Mr. Pringle would definitely approve. Two slightly charred thumbs up!

Awesome idea!
