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.

Paul and Colleagues,
Quite awesome and the smelting pot demonstrates how much high
temperature can be created. Some version of this would I think be
adequate for Rolf's first proof of concept trial, better than using
his gasifier. How big have you made one without compromising the key
parameters?
Our colleagues are responding to the wake up call, and when a few $$
are available, the ceramic project will be able to draw from the best
people and technologies in the business. In the mean time, we can all
contribute to assembling Rolf's projects needs, and I hope others will
join in and help make it happen.
Doug.

Doug,
The AVUD method is ignited at the level of the "grate" (actually a
pipe with holes on side and bottom, so the char can pass around the
pipe, drop below the hot zone, and be extracted at regular
intervals). The heat rises and pyrolyzes the biomass above, and
additional fuel is added regularly on top of the fuel pile. That
makes it a continuous process. No need to stop.
The tarry gases exit and are combusted with turbulent air, coming
from an air compressor. The combustion is quite complete and
clean. This has similarities to the Dasifier made by Agua Das
almost 20 years ago. You should read these materials at my website:

and see a 2012 video with Das himself melting metal with woodgas at:

Many years ago Das was one of my teachers and mentors, and a good
friend of Tom Reed.
