[Gasification] Torrified woodchips as a gasifier fuel

[john shelzi]

Rolf, can a diesel run producer gas as well as WVO at the same time?, & for that matter, can a gasoline engine run gasoline, along with producer gas at the same time? John.

  Hallo Ken,
if your Lister produces soot running on wvo,check compression, timing and 
iny.pressure. If it is very cold, preheat.
My 12/1 runs on very rough wvo several hours every day and there is no soot. 
Odor, o.k.-- but this is still better than diesel fumes.(to me)
Anyway, my aim is to use the limited wvo as detonant for less limited 
woodgas in a future.
