Tom, So in the batch type Missouri kiln, the wood gas is wasted along with a certain amount of propane or natural gas that is added to and burned within the process. Wow, what a waste!
Why not chip the wood and place it in a large TLUD batch reactor that would produce charcoal and syngas. The syngas could be used to make ethanol or methanol. The same TLUD reactor could serve as a dryer and heat exchanger. The initial drying of the wood chips can be done quite inexpensively using a compost fleece. Thanks.
