As far as a pre-drying arrangement, using chimney heat to warm a feed auger works well, BUT, don't tempt an engineering firm to design this, as it is a "cutting edge" method (way out of their area of knowledge). Look to people directly involved in gasification, Andy Shofield or one of the longstanding posters on this list would be a good start. I can assist at a later date, on this if needed, but I'm currently booked to at least mid June of 2011.....
