This patent changed the way I look at pyrolysis:

Every word counts and it deserves special attention. It reminds me of the TLUD design.

Some good background information:

I don't know about you guys but Monday I'm hitting Lowes for some flue pipe supplies before going to work.

he author, Gary Gilmore, explains how he designed a charcoal retort from steel drums. This is a smoke free design also the flare could be put to use.

Charcoal by Gary Gilmore video 1

First make the retort by adding air holes to the bottom of a steel drum.
Then make the afterburner by turning another steel drum into a tube.

Then start loading the wood (no more than 20% moisture) tightly packed into the retort. (This contains a great description of wood as nature's battery).

Once you have the wood packed in the retort, build a small fire on the top. (There is a nice description of a top lit retort system). Once the small top fire has caught, ad the afterburner (the tube) to the top of the retort.

This is Puffergas' first test of growing potatoes in switchgrass compost. The potatoes were grown in containers and charcoal was added to the compost.

Dear Joshua,
