<DIV><FONT face=Arial size=2><STRONG>Both Thomas and Kevin have offered good
advise, and the only thing that I can offer, is that you talk about biomass
pellets, rather than wood pellets. As we know that many agricultural wastes,
twiggy shrubs and leaves are often used for pelleting, their higher ash and
silica content will create sintered clinkering. </STRONG></FONT></DIV>
<DIV><FONT face=Arial size=2><STRONG></STRONG></FONT> </DIV>
<DIV><FONT face=Arial size=2><STRONG>Collect samples from through out
the bed depth above and below the oxidation air/fuel interface, and examine
the carbonized pellets to see if they are extruding tiny beads of melted ash. If
so, then you cannot improve anything, other than to change to a known wood
pellet, and that may change your end result. Kevin's advise then takes over, and
you should study and learn to understand how these differences affect gas
making.</STRONG></FONT></DIV>

<DIV><FONT face=Arial size=2><STRONG>Hope this may be of
assistance.</STRONG></FONT></DIV>
