The Making of Capillary Action Alcohol Stove

Capillary action alcohol stove in action

This is a simpler stove to make. There is no epoxy needed to seal parts like the Open Jet Alcohol Stove. All i need to do, were just marking, cutting and crimping the grooves for the capillaries. This type of stove uses the crimped grooves as capillary action for the alcohol vapors to escape through it. 

When the stove is lighted, it takes about few seconds to heat up the stove and boil the alcohol inside. In no time the alcohol vapors escape through the crimped grooves and catches the fire from the center hole. Immediately it creates the vapor jet flames. From my initial observation, the jet flames from the capillaries(sides) are bigger compare to my previous Open Jet Alcohol Stove.

I have not run any boiling tests with this stove so i don't have any numbers to analyze the efficiency of this type of stove. I have not prepare much detail steps in making this stove but if you interested, let me know. Below are some of my photo shots i took while making the stove.

All you need is a regular beer can to make one stove.

Regular beer can

Prepare all the markings for cutting and crimping.

Markings

Cut the beer can into the top and bottom parts of the alcohol stove.

Stove parts cut from a single beer can.

Cut open the top of the can, crimp the grooves.
