Hey guys, new to the forum and thought I'd post my first gasifier stove that I built today out of recycled metal. Pretty much just experimenting with ideas at the moment, and will most likely install a rocket stove into my dwelling next summer, rather than something like this...but who knows, I've had pretty decent results with this little experiment. Maybe i'll end up using them for hot water, and mobile uses. I was also thinking of copying the biolite camp stove and putting thermoelectric generators on them so that I could have mobile energy, or supplemental energy to a battery block. I know that's not really mobile with batteries, but I will be travelling by horse and buggy when I do plan on needing it for mobile uses, definitely not a backpackers camp stove
This is a TLUD gasifier stove. -Top Lite Up Draft-. Made from a 20 lb propane bottle with a stainless steel cooking pot custom fit inside. At the bottom of the cooking pot around the sides are 24 3/16 holes, and at the top around the sides are 60 7/32 holes for the jets. This equals roughly a ratio of 1 to 5 which is ideal for a TLUD. At the bottom of the propane tank there are multiple holes cut for air intake.
A 10x12 log cut into kindling, cut into 6 inch lengths to fit, will fill this set up three times, and each burn lasts for roughly 2 hrs, not including the time for the embers still giving great heat to burn out to ash. So roughly 6 hours of fire off of one log. Pretty darn efficient if you ask me, not to mention I get biochar if I want it, or just heat from the charcoal for thermal mass set ups, if I want that as well.
Next on the list is to supply blower air to the bottom, and to build the same set up out of a 100lb propane bottle for house heat through a thermal mass set up. As well to set up a chimney to help draw more air, though I may not need it with a blower set up. Obviously will need the chimney if I put it inside.
