<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><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>
