As you know small dimensioned biomass generally chars as a first
stage of combustion. If the char moves into an air starved zone in
the furnace it will cool a bit and collect. This happens past the
end of the grate. It forms a long Kilimanjaro shaped mound in the
pipe. The peak is about half the pipe diameter. Perhaps its a
stretch, but it could be described as half of a convergent/divergent
nozzle. The acceleration over the peak seems to prevent further pile
growth, a form of mountain top removal, char-coal mining. I'm not
the first to link coal to Kilimanjaro.<br>
<br>
I have not tried to turn it into a char maker. It is possible that a
pot could be placed under that portion of the pipe, et viola. For
now it remains a known unknown.<br>

RWL: I have totally missed the possibility of a char output in
your design. I can't even see a Venturi possibility.. Can
you explain a bit more on how that can be accomplished? Have
you accomplished any char preservation yet?<br>
<br>
Thanks. Ron<br>
