Great footage. Thanks for the link. I note the fuel preparation.
I saw a gasifier yesterday here in Brazil that was used in 1943 on farm tractors for cane production. Wood blocks and charcoal were used for fuel.

And grate shaking http://www.youtube.com/user/bioenergyken this is a rare new surfacing. it is a video of the imbert factory making gasifiers in 1942. they show all the steps. it is great. lots of little details that we don't usually see. there are some interesting things to see in the video. in particular, between 2 and 3 minutes, there is a quick shot of how the imbert did its grate shaking. bear and i are currently rather interested in this question and doing lots of testing to characterize the impacts of different shaking mode types and different grate hole sizes. as we all know, bell packing is a major challenge for long untended running. needing to poke a rod down the rig every once in awhile is unacceptable for untended genset operation. expert operators of car rigs tend to do this regularly, and don't think much of it. for a newbie or a regular run situation, you need to eliminate the knowledge dependency that only the expert has so they know when and why to do this. the imbert apparently had the side shake design via a pivot point going through a gimble ball. this is a mode i was playing with in the phillipines given challenging fuel there. now we're trying to formalize the performance of this vs vibrator, vs in/out shake vs rotary. oddly, we're finding up and down motion to potentially be more effective than side to side or rotary motion. i thought such would contribute to packing above. but so far it seems to do the opposite. still much to learn on this. in the interim, we need to get this video translated from sweedish. anyone here who could do the translation? jim ---------------------------------------------------------------------------- -- 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 [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 _______________________________________________ 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
