Greetings Billy, and list members.
In most designs of "homemade" downdraft gasifiers, IMO the feedstock can only push moisture content to the area of about 15%, however, if an "air dryer" is used in the tuyere air, 18% is attainable. Why I say the above, is that on the opposite side of things, having too little moisture will cause an excess clinkering due to the gasifier running "too hot". In your case a simple water injector system could be used to temper the overall reaction temperature, AND it kept at the high-end of reaction, could also employ the water/gas shift just above the reduction zone. this would have to be carefully managed, but could be done. Most gasifiers suffer from a massive excess's of moisture, my personal observations are that 4-9% is ideal for most feedstocks total moisture (air and feedstock combined). hope this helps.

Is there any unusual drawbacks to the gasification of torrefied biomass (>1% moisture) as opposed to dried wood (<20% moisture) _______________________________________________ Gasification mailing list [email protected] http://listserv.repp.org/mailman/listinfo/gasification_listserv.repp.org http://gasifiers.bioenergylists.org http://info.bioenergylists.org UNSUBSCRIBE HERE; http://listserv.repp.org/mailman/listinfo/gasification_listserv.repp.org No virus found in this incoming message.
