<DIV><BR></DIV>
<DIV dir=ltr>
<DIV>I am looking to build a GIANT retort. I have an unlimited supply of
compressed wheat straw bales (approx. 500,000lbs per yr). They measure
4'x5'x3' and weigh about 400lbs each. I am wanting to build a retort
large enough to hold anywhere from 1 to 10 of these bales, probably
horizontally. My question is will these bales fully pyrolyze "as is"
with perhaps a few inches of airflow on all sides and between bales inside the
retort? <BR><BR></DIV>Thank you,<BR><BR>Mike<BR></DIV>
