Dear Anand and All:
Thanks for your comments. I am so glad that the TLUD principle, first used in our cook and camp stoves about 1985, is finding broader uses now. It depends on the facts:
Wood is comprised of 80% Cellulose and only 20% lignin
When the fuel is lit ON TOP, the cellulose is vaporized:
Celllulose, a great fuel which breaks down about 330 C to form H2 and CO
C6H10O5 + heat ===> 5 CO + 5 H2 + C
This gas is useful for cooking and running engines.
The 20% lignin in the wood is uniformly converted to charcoal.
This works on wood at any scale. The cellulose gas is relatively clean and is fine for cooking as is. For engine use, passing the gas through a container of previously produced charcoal is sufficient to cool and clean it for engine use.
Yours for clean cellulose gasification and char production,
TOM REED
