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

<p>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?<br>
</p>
<p>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.</p>

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.<br>
<br>
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: <br>

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