Dear Tom, we regularly supply charring kilns made out of used 55 gallon drums. The kilns are based on the TLUD principle. The cost of a kiln plus an extra barrel for storing the char, is about US$100. We have sold more than 100 such kilns in India and have also trained a number of persons from India and Africa. These kilns are so easy to manufacture, that we ask the trainees to photograph and take measurements of our kiln so that they can copy the design. In many instances, people buy a kiln from us, because they feel that their local fabricator would be better able to copy the design from an actual object than from a blue print or a photograph. The advantage of using 55 gallon drums is that used drums are available at a relatively low cost, and the kilns are portable. Instead of transporting the biomass, one transports the kiln to the location where the biomass is available, and brings back only the charred material, which weighs only a third as much as the biomass. Yours A.D.Karve
