[Gasification] Getting both heat and char .....

[Paul Anderson]

Doug,

I made something like the Dasifier with about a 30 Liter capacity.

Similar, but in the AVUD format, the Chip Energy biomass furnace 
(chipenergy.com) was made four times.  About 2 meters tall, including 
the combustor with hydronic heat exchanger.   Produces about 200,000 kW 
thermal.
