RE: SB: Re: wood stoves for sb

["Wil Maertens" <biofab@ricestraw.com>]

I believe a major problem of facilitating the use of straw in co-generating
plants is the potassium content of the straw from manual fertilization for
higher yields in the maturation of cereal grain (seed) i.e. rice, wheat,
barley, etc.  The potassium combined with the silica of the lignocellulosic
straw combine to make GLASS. This glass diminishes the use of the furnace by
coating and clogging the fire box. Rice straw causes three times as much
glassing as wheat straw for there is three times as much silica in rice
straw.
Rice straw must be left in the field to weather in the rain which depletes
the content of potassium substantially. This special straw is called gray
straw because of its condition and color after bleaching in the sun and
washing with the autumn and winter rains. This straw can be baled and used
for generation if the co-gen plant agrees to use the straw.  Wil

In principal there is of course a big difference between smoulding straw in
a field and brightly glowing pellets, but as I understand it, one of the
obstacles to large-scale use of rice straw as biomass for generating
electricity has been that even when very efficiently burned, some toxic
wastes are generated...but I could be wrong.
