Please do us all a favor and don't change the "Subject". When you do the
archives lose the thread and it's hard to follow it later. 

Thanks

Subject: [Stoves] Fireballs production. was Re: Rocket Fuel?

Dan and Jeff,

The newspaper Dan mentions is dry when you twist it.  But if made wet, it
will
not twist well but will compress more when squeezed.  Jeff has a wet process
for fireballs.

Jeff, the package of fireballs you sent me has arrived.  I am impressed by
the
number of types (mixtures), but with so few of each type I cannot do much of
a
test burning and still have some as demo items.  I hope to test some 
tonight in
a small gasifier.  The shapes and sizes (mixed diameters) are excellent 
for fuel
feeding.

There is a dung-burning rocket stove with nearly vertical gravity feed of
fuel
that would probably easily use the fireballs.

How big of a batch could you make in 5 weeks and ship to Stove Camp?  Those
of
us there would treat them with respect and give good feedback.  Some with
charcoal included are fine, but pure biomass ones are what we need most.

Jeff, although there are different qualities of fuel, basically fuel is 
fuel is
fuel, and the "value" is in the heat energy of BTU or MJ or kilocalories,
etc.

BUT, what you have that is so exciting is a different way to "create" the
fuel
from low-value biomass.  Can you direct us to (or do the write-up with
photos)
of details about the "agglomerator" and however else you can create the
fireballs (apart from hand squeezing).  When people can shovel in the raw
materials and get fireballs to fall out (and just need sun-drying), THAT is
what can make the fireballs so truly valuable.  How could we make one 
for Stove
Camp?

Low density is less of a problem if the quantities of usable fuels are much
greater.

Pellet machines work that way (raw material goes in, fuel comes out), but
are
very expensive, energy intensive, and fussy about the raw materials (mainly
sawdust).  But pellet making has become an industryRichard Stanley's 
briquette-
making methods and presses are major improvements for the low-cost side of
creating a biomass fuel, but the method is somewhat labor intensive (and we
await Richard's peddle-step-powered continual-operation device).  So, the
device for making the fireballs is the hinge-point that will take fireballs
into the mainstream of fuels or keep fireballs on the "backburner" as an
interesting novelty fuel.

We wish you 400% success, and more.

Paul
