Hi Cuong, Standard updrafts do not have a tar cracker.
One idea that I never tried with an updraft was to take the working gas off above the charcoal area. Next with some kind of fan suck the tarry gas off the top and route it back up into the bottom (air inlet) of the gas producer. Good way to tar up a fan and I doubt that it would be easy to balance but maybe as a last resort. Anyhow downdrafts natural crack tar to some point. Good luck, Jeff On Tue, 2011-12-06 at 22:18 -0800, quoc cuong Pham wrote: > hi all! > I design updarft rice husk capacity 100kg/h.there is a problem tar > high,process level of Moist. > Fuel use burn direct and no craking tar. > discontinuous and working gas is laborious, low-built efficency.there > is betterment which way neither. > thanks! > cuong.pq _______________________________________________ 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/
