yes, but remember that all that run these fuels to date are doing so by tolerating a dirty gas non tar solving reactor, and fighting the tar problem in the filtering. on the low tech end this is nearly always a water scrubbing system, which really just moves the toxic problem somewhere else, and actual real world running is highly unattractive. yes, it will work for the demo, but the ongoing issues with the bongwater cofferdam challenges health, regulatory and general pleasurable concerns. everyone who actually runs these systems do not like them. most of them call/write us wanting a small and clean system without all this mess. and sadly we have to tell them we can't yet do it for their fuels. yes, our system will "run" rice husks, but it will not do it to a clean enough gas for our filtering system to process. nonetheless, the reactor will make gas from rice husks just like these others, i just don't think that is adequate. i would suggest that we aren't really "running a reactor on rice husks" until we are reasonably solving the tar issues in the reactor during the process, and not tossing them downstream. a open core reactor will not control the zones and cracking conditions adequately enough to do this. even the multi stage air inject systems still don't get there, though they are much better, yet still require a big downstream filtering solution. until you can get rid of most of the downstream filtering system, you will not be able to deliver a full system with reasonable use logistics and price points. solving problems with more complexity and more parts tends to render the end only relevant for the government financed. this is what we're trying to avoid. my biases of course . . . j > Tom > > -----Original Message----- > From: Gasification [mailto:[email protected]] On > Behalf Of Jeff Davis > Sent: Wednesday, January 30, 2013 9:44 PM > To: [email protected] > Subject: Re: [Gasification] Power Pallet > > > Rice husks was my favorite fuel for the Gas-of-Fire 1000, open top down > draft, but that was best suited for thermal applications. > > > > Jeff > > _______________________________________________ > Gasification mailing list > > to Send a Message to the list, use the email address > [email protected] > > to UNSUBSCRIBE or Change your List Settings use the web page > http://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenerg > ylists.org > > for more Gasifiers, News and Information see our web site: > http://gasifiers.bioenergylists.org/ > > > > _______________________________________________ > Gasification mailing list > > to Send a Message to the list, use the email address > [email protected] > > to UNSUBSCRIBE or Change your List Settings use the web page > http://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org > > for more Gasifiers, News and Information see our web site: > http://gasifiers.bioenergylists.org/ -- Jim Mason Website: http://www.whatiamupto.com Current Projects: - Gasifier Experimenters Kit (the GEK): http://www.gekgasifier.com - Escape from Berkeley alt fuels vehicle race: www.escapefromberkeley.com - ALL Power Labs on Twitter: http://twitter.com/allpowerlabs - Shipyard Announce list: http://lists.spaceship.com/listinfo.cgi/icp-spaceship.com _______________________________________________ Gasification mailing list to Send a Message to the list, use the email address [email protected] to UNSUBSCRIBE or Change your List Settings use the web page http://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org for more Gasifiers, News and Information see our web site: http://gasifiers.bioenergylists.org/
