[Stoves] Wood Tar Experiments with a Cookswell Mini Kiln

[Teddy Kinyanjui]

Teddy Kinyanjui is improving his charcoal mini kiln, and his wood tar
removing process.  Does anyone on the list have any recommendations to help
him improve the charcoal and the wood tar yeild?

We are trying to (a) reduce the amount of emmisisons from charcoal
production and (b) Condense and recover as much of the smoke into a usable
product for your home/farm. Wood tar - the following is an explanation from
the good folks at Food and Agriculture Organization of the United Nations
(FAO) about what is going on in this process. 

"The non-water component consists of wood tars, both water soluble and
insoluble, acetic acid, methanol, acetone and other complex chemicals in
small amounts. If left to stand, the proligneous acid separates into two
layers comprising the water insoluble tar and a watery layer containing the
remaining chemicals. Recovery of the water insoluble tar, often called wood
or Stockholm tar, is simple - it is merely decanted from the water phase.
This wood tar has uses as a veterinary antiseptic, a preservative for wood,
a caulking agent, and as a substitute for road tar"
