Flammable Gas from Biomass

[David Yarrow]

After nearly a week off while i was away on a trip north of Lawrence, Brad Rush and i made several successful steps toward a permanent TLUD biochar stove to build at 4 Oaks Farm. last friday we did a very successful fifth test burn at night with our experimental apparatus, and recorded some beautiful flame photos and videos:

another burn on sunday night was not so successful. we experimented with adding leaves to twigs and stems, but they clogged the air flow and choked the burn, creating lovely, thick smoke. we salvaged the burn by disassembling the chimney and igniting the smoky gases rising out of the barrel, and ended with a reasonable batch of biochar.

we are buying equipment and insulation to build a better, more efficient, permanent TLUD at 4 oaks community farm. in april, we will publicize several biochar workshops at 4 oaks and elsewhere in northeast kansas. we will teach folks why and how to make biochar in their own TLUD, and how to prepare and deploy their biochar in soil to create a "microbial reef" in their land.

we will also build a smaller 30-gallon TLUD that is portable to take to fairs, festivals and farmers market to demonstrate how simple, cheap and easy biomass gasification and biochar production can be.

before i leave kansas in may, i will also build and test a 50 & 30-gallon nest kiln & retort, with a rocket stove underneath to kickstart the burn. this will allow 4 oaks to turn even limbs, logs and hogs into char. and leaves, straw and hay, too.

for a green & peaceful planet,
David Yarrow
