Dear Doug and all: The Toplit Updraft gasifier produces a different gas (plus 20% charcoal, mostly from the lignin) than the downdraft gasifier. I believe it may be a cleaner gas, since cellulose (~ CH2O) vaporizes to produce a different gas (CO + H2 + ?) than the lignin.
As soon as we get some warm weather, I'll try to measure the tar content from each, using my 2 kW generator and a 5 gal tar filter made from the charcoal. Comments, suggestions?
