ABSTRACT:
A furnace (10) in which bark or other cellulosic fuel (64) is burned on a traveling grate (24). Char (62) separated (48, 54) from the furnace exhaust gases is reinjected into the furnace beneath baffle plate (40) in such a manner that the raw bark (64) being introduced onto the grate forms a protective cover over the char (62) thus preventing the relatively light char particles from becoming reentrained in the gases before they are completely combusted.
