<DIV><STRONG><FONT face=Arial size=2>You ask:</FONT><BR></STRONG><FONT
face=Arial size=2><BR> >You mentioned that some of the wood chips had
lots of fines. Do you preprocess them to eliminate those
fines?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><STRONG>At this time no, because we are testing how
these types of chips behave in packed beds. It's all about surface area of the
fuel changing the speed of gas making within your chosen rage of gas outputs.
The rule of thumb still applies, finer fuels mean smaller gas outputs and or
gasifier size.</STRONG></FONT></DIV>

<DIV><FONT face=Arial size=2>>Are the trees debarked before
chipping? </FONT></DIV>
<DIV> </DIV>
<DIV><STRONG><FONT face=Arial size=2>The tree tops we use are not debarked, but
after drying in a log dump, much of the bark falls off as handled. Bark in
itself, is not a problem in a gasifier, but mud and dirt in the bark, certainly
can make for slag or clinker problems. </FONT> </STRONG></DIV><FONT
