<p>Hi Gasification Colleagues,</p>
<p>For those interested in this discussion on rice husks, I posted
an article on the Fluidyne Archive a few years ago about the
issues of gasifying agricultural wastes. The photos will enlarge
by clicking on them. We did enough testing at that point in time
(1984-5) to study the practicality of doing it both small and
large scale for boiler application for an associate company that
had trouble using it as blown combustion fuel. It proved a good
way to sand blast the internal surfaces!<br>
</p>
<p> If gasified, these types of siliceous wastes are prone to packed
bed channeling, as the air flow will push through in lower density
areas chasing the oxidizing surface carbon. Their use for clean
gas applications remains an issue of filtration, rather than
gasification. The use of cheap water scrubbers create huge
environmental risk to ground water, and it would be fantastic if a
break-though in filtration could be found, that was affordable and
scalable to end applications. <br>
</p>
<p>Any researchers of this subject, should add to their Bibliography
"Gasification of rice hulls: theory and praxis." by Albrecht
Kaupp, 1984. ISBN 3-528-02002-4 (GATE) (GTZ) German publication
in English. Possibly it is digitally recorded and worth a search.<br>
</p>
<p>Happy New Year from NZ.</p>

<div>Happy New year to all..hope it will be prosperous!</div>
<div>Tom, interesting article. I have not finished it but
wondered if you have any reaction from the all power lab
people? Angie and I are planning a trip to Viet
Nam..nostalgia for me, curiosity for her. and a stop at his
lab would certainly be interesting. The air flows noted are
within parameters we worked with and are quantified in a
couple of other studies.</div>
<div>I will keep you posted.</div>
