Char reinjection system for bank fired furnace

Patent ·
OSTI ID:6354298
A furnace in which bark or other cellulosic fuel is burned on a traveling grate. Char separated from the furnace exhaust gases is reinjected into the furnace beneath baffle plate in such a manner that the raw bark being introduced onto the grate forms a protective cover over the char thus preventing the relatively light char particles from becoming reentrained in the gases before they are completely combusted.
