<div class="moz-cite-prefix">Hi Crispin and Jock,<br>
Interesting to see these new devices take shape.<br>
I have seen prices for high percentage grass or oat pellets (mixed
with 10-20% wheat shorts) and pure oat hull pellets in the
135-150$/tonne range, in bulk. I think the moisture might
typically be higher than wood pellets, or at least more variable
than premium wood pellets, and of course 5-10 times the ash. Some
of these have left significant deposits on boiler heat exchangers,
could/should be better with pyrolysis, but I guess that's what
beta testing is for :)<br>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">I
am interested to know how the economics of the pellet stoves
that produce a char byproduct compare economically with
natural gas. It is noted in the article that the sales of
pellet stoves have fallen off largely because of cheaper
natural gas, a situation which may change soon.</span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">If
NG is the fuel of economic choice, I am wondering how the
economics look for biomass pellets (burned whole) and for
biomass which does not burn all the available carbon (which
contains about 2/3 of the energy in the pellet when loaded).</span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">If
about ½ the carbon is remaining as char (yielding 25% char)
there is a 33% fuel cost penalty for the same amount of
energy.</span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">It
sounds as if you may have the numbers to go with these
solutions. If it looks good, then people using the char like
greenhouses may find the grass pellet option attractive (as
is the case in Ontario at the moment for switchgrass
pellets).</span></p>
