<DIV>In a TLUD it's all about the uniformity of air flow. <BR>If corn cobs
were cut to the same length, they just might be sufficiently uniform.</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial># I think it is a bit more complex that "unifiorm
length." With a given species of fuel, I think it is more a relation of
relative size (that would determine pressure drop and uniformity of flow
across the fuel bed), and surface area and diameter of the fuel particle.
(That will have a large impact on fuel burning
characteristics.) </FONT></DIV><FONT face=Arial></FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>For example, consider a TLUD running on wood spheres of
say 1/4" daimeter, and 1" diameter. Such stoves would have quite different
operating characteristics.</FONT></DIV>
