Hi folks, today I want to show you one of the simplest improvised wood biomass stove design that I have ever seen. This stove design takes less than 5 minutes to make and is shockingly effective. So lets get started.
First locate a small soup can. Sady, these cans are all too common in the woods. Then, using a can tap, make a series of 8 evenly spaced ports at the bottom of the can. Next, create a matching set of 8 ports at the top of the can. Now, using your finders, crimp the edges along the top rim of the can. Watch your fingers, those edges are sharp!
Finally, using a nail or the tip of your knife, drive a series of evenly spaced port holes along the circumference of the can. These tertiary ports should be driven in near the bottom third of the can. The finished stove takes less than 5 minutes to craft.
This stove is designed for a fire that burns from top to bottom. For this demonstration, I'm using 1 cup of hardwood pellets as the fuel, in the wild, I find small dry twigs to work just as well. When loading the stove, it's important to make sure that your fuel sits just below the top ports.
Using a vaseline coated cotton ball as tinder, I start the fire.
Now, it takes about 3 minutes for the flame to establish itself in the wood pellets. Once the pellets starts burning, the genius of this design is revealed. The fire near the top of the stove consumes the air inside of the stove and creates a vacuum, this vacuum then sucks up air from the bottom ports to power the flame. Now as the wood burns, it emits large amounts of wood gas which normally would leave the flame as smoke. However, with this stove design, the vacuum caused by the flame also sucks in fresh air from the top ports, this air mixes with the wood gas and combusts, resulting in a secondary flame which is super efficient and almost smokeless.
This stove can be used for heating or to boil water. When boiling water, I use an improvised pot stand made out of an old metal clothes hanger. 2 Cups of water can be brought to a boil after 12 minutes on the stove. This stove is extremely efficient in channeling thermal energy towards the pot, even at full burn, the sides of the stove can be touched. With one cup of wood pellets, I measured the total boiling time of the water to be 43 minutes.
Over time, as more and more wood fuel is burnt into ash, the bottom ports will slowly become clogged up with ash, however, the tiertiary port holes will continue to suck in fresh air and keep the fire burning until almost nothing remains of the wood.
Now, 1 hour and 3 minutes of burn time, the fire finally died down. This stove design is incredibly easy to construct, it can be made in the wild with limited tools This design is also extremely fuel efficent. In a wilderness survival situation, such a stove can greatly reduce the amount of wood fuel needed to meet cooking and heating needs.
