Production of biomass spheres from biomass is inherently more costly than
cylinders, pellets, or briquettes. However, if you have identified a market,
biomass spheres can be made if the price is right. I know someone who has
developed technology for producing charcoal spheres for fuel, and if you could
tell him the feedstock available and its present form, along with sphere size
you felt the market wanted and the price he could sell them for, he might be
interested in giving you a firm proposal.</STRONG></DIV>

Fuel preparation is a costly nuisance, in terms of time, convenience, and
capital, but it has to be done. Stove systems are a compromise between many
factors, one of which is fuel preparation. </STRONG></DIV>

as space filler in TLUD reactors<BR><BR>Dear Martin, <BR><BR>I often
determine the particle density here in the lab using free flowing<BR>sand.
If the particle density of the fuel is determined (g/cc) and you know<BR>the
weight of fuel packed in a known volume you know the volume of voids
and<BR>can determine the air speed - I am thinking.
