Colleagues,</STRONG></FONT></DIV><FONT face=Arial size=2></FONT>
<DIV><BR><FONT face=Arial size=2>john, this is a hard problem, but there are
some partial fixes that<BR>might get things to tolerable. it can likely be
solved without a 50k<BR>extruder or giving up<STRONG>.</STRONG></FONT></DIV>
<DIV><FONT face=Arial size=2><STRONG></STRONG></FONT> </DIV>
<DIV><FONT face=Arial size=2><STRONG>Jim offers some interesting possibilities,
and quite tempting if no explanation was forthcoming. I have explained the
cause, and the briquette still has to turn to carbon, no matter how you
get the briquette to the carbonizing temperatures which expands
the individual compressed fines. Binders would help if you have buckets of tar
to get rid off, but this is not the case in John situation, explained to me in a
separate earlier communication, that I missed in my early scan of my
in-box.</STRONG></FONT></DIV>

<DIV><FONT face=Arial size=2><STRONG>Jims final question:</STRONG></FONT></DIV>
<DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV>
<DIV><FONT face=Arial size=2>what happened to the high resin block
fuels?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>

<DIV><FONT face=Arial size=2> </DIV>
<DIV><STRONG>High resin block fuels as you refer to them, can cover most species
of conifers (pines), although some seem to have more resin when cut green. If
the gasifier is designed for these soft woods, which require
smaller dimensions, everything passing through the bed carbonizes. The
larger dimensioned hardwood block gasifiers cannot handle conifer blocks, and is
why many in Europe get into tar problems, using WW2 design parameters, but not
sticking to the regulated fuel specifications of that era.</STRONG></DIV>
<DIV><STRONG></STRONG> </DIV>
<DIV>isn't gasification fun?<BR><BR></FONT><FONT face=Arial size=2><STRONG>I can
only concur that when you stop learning, you also stop
breathing.</STRONG></FONT><FONT face=Arial size=2><STRONG>(:-)</STRONG></DIV>

<DIV><STRONG>Hope this provides more understanding.</STRONG></DIV>
