Abstract

See full text

A system for drying solid fuels prior to injection and burning in solid fuel boilers is described. High moisture content solid fuels such as bark, sludge, wet coal, are preferably dried to some degree before they can burn. The present invention incorporates a delivery chute in which combustion gases dry the solid fuel before it reaches the combustion chamber of the boiler. In one embodiment, the combustion gases are drawn through the delivery chute to remove moisture from the incoming fuel and then the gases flow back into the boiler. A second embodiment directly exposes the wet fuel to the combustion in the boiler for a sufficient time to remove a substantial amount of moisture before the fuel is spread onto the solid fuel combustion region.
