<o:p></o:p>Dear Tom,<br>
We have tried using charcoal for engine quality gas in 2 types of
gasifiers. One was our own design, downdraft with tuyers and throat,
the other design was also downdraft grateless design. At first we
had some clingers problems, later fixed with adjusting air volume.
Gas comes out pretty clean. We washed for cooling gas, in a venturi
type washer, used wood chips/sawdust/charcoal for filter medium.
Charcoal used was kemiri (some type of nuts grow in Indonesia)
shells, coconut shells, regular wooden charcoal pieces and briquette
charcoal pieces. <br>
The result was OK. Because charcoal cost here is more, we stopped
with the charcoal gasification, now concentrating on rice husk and
wood chips.<br>
Any other details you need to know, we will try to answer. <br>
Actually I have almost 30 tons of charcoal pieces in stock, we were
originally thinking to built gasifier for use in our own generator.
But the charcoal pieces we can sell for $ 300.00 for ton. Rice husk
here cost $ 39.00 a ton and we get almost as clean gas from rice
husk as charcoal.<br>
