      Yes, tars and fly ash are definitely a concern and need be dealt with --
another reason to consider just using junkyard engines, with several kept in
reserve, I guess.  8-)

      Another concern -- I suppose the heat from cogen could help with drying.
Also I'm thinking of building some sort of hydraulic (running off the genset
engine, of course) "crusher" for pallets. But also thinking of many other fuel
sources than wood chips -- corn cobs, cattail leaves, etc. Eventually a
pelletizer would be nice to have.
      Corn is another very strong option, especially waste (damaged) corn.
      OTOH, how crucial is it to have really dry fuel? If you look at the Kuenzel
boiler design (http://www.kuenzel.de), they are claiming complete gasification of
green wood, albeit using forced draft for both primary and secondary air, as well
as an oxy sensor in the flue and computer controlled.
      Which may be the way to go. I'd asked previously about the possibility of
building a gasifier that burned logs downdraft style, with forced draft, but got
no real response.
