Dear Doug, Brian and all
To what extent can you clean today's gas by passing it (cooled to about 150 C) through a barrel of tomorrows REASONABLY DRY fuel, thus permitting you to burn all the tars AND finish drying the fuel?
While a moisture content less than 20% is desirable for gasifier fuel, I suspect it should not be bone dry for long runs because it becomes autopyrolytic and won't retain a level pyrolysis zone.
