<div><font size="2" face="Arial">Was there not a post a month or two ago about
putting rice hulls or saw dust into a can with a hole in the top. This
then was put in the reactor with fuel around it. The heat of the
stove pyrolyzed the contents of the can and produced wood gas which exited the
hole and was burned in the secondary. I forget who posted it and
could not find the post, but it was a wonderful idea. I tried this
with saw dust and with pellets and both worked. The can needs to be
raised off the grate some so pyrolysis will finish before
the migratory pyrolysis front goes out or it smokes on and on. A
single screening of the almond hulls will seperate the small pieces
and dust out for use in the can, while the larger pieces will be the outer
fuel. This way the small pieces are used without clogging the
primary air passage. Perhaps pieces that are too large could be
used in the can as well without having to chop them up. The can
cannot be to big or the power level is reduced. The can which
worked for me was .4 the diameter which is 1/6 the area of the
reactor.</font></div>
