Lori, he posted yesterday on [email protected] Gary Gilmore is the moderator of that group, and he has posted some videos on YouTube showing how to make charcoal using a two barrel TLUD system. I copied his design, and have made 124 barrels of biochar and charcoal. There are three videos, and here is the first one: <http://www.youtube.com/watch?v=3wgTb9i8g14> In my system, I separate the barrel containing the biomass from the chimney barrel with two pieces of 1/2" rebar for secondary air. There are 1/2" holes spaced about 3" apart all around the bottom of the lower barrel for primary air, and when these holes are "illuminated" or glowing, I shovel dirt/clay over all of them. Use lots of dirt or clay because these holes must not allow any air into the barrel. Then remove the chimney barrel and cover the bottom barrel with an airtight lid. (I use a very heavy flat plate of steel.) I use wadded paper balls from old training materials (Xerox paper b/w) and small branches to get the top lite really well. There is no smoke except when you first add the steel cover, if you get a good bed of char on top of the biomass in the barrel. During the burn, it may be necessary to add very small branches and more paper balls if you see any sign of smoke, such as if your material is a bit green or damp.
