"Farm scale" depends on where in the world you are. ;o) > 3: What is the presently intended "end use" for the char you > wish to produce? > for biochar field trials > 4: Do you have a use for the energy in the pyrolysis gases? no > immediate use ..this can be used to dry your fuel. I put my tar vapor flare inside my fuel hopper, which sits on top of my Imbert-style gasifier, the tar vapors are drawn into a 2" pipe hung around my 1/2" "tar air pipe" which ends ~4" inside the tar vapor pipe that hangs down just over and thickens the Imbert type combustion zone lens. > 5: Please confirm that you are indeed interested primarily interested > in charcoal production, OR if perhaps you are interested in > gasification of biomass (either wood or charcoal) for engine use. > biochar production ..if you draw more than 1 cubic meter of gas per second per square centimeter of Imbert hearth throat area, you will produce _both_ "good engine quality gas" _and_ "charcoal", according to WWII "Gengas" litterature, I dunno how this does in the "biochar" role, though. ..in WWII, this regime was called "overload" because it wasted fuel as charcoal dust clogging up filters and made the gasifier and its piping etc fairly hot. IME I got charcoal chips out my ash "grate" auger and probably a fair amount of charcoal dust in my filter/coolant water, it's all black. ;o) -- ..med vennlig hilsen = with Kind Regards from Arnt Karlsen ...with a number of polar bear hunters in his ancestry... Scenarios always come in sets of three: best case, worst case, and just in case. _______________________________________________ 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/
