ABSTRACT:
Method of improving the operation and efficiency of a steam generating furnace fired with high moisture content fuel, comprises providing a drying shaft parallel and offset from the combustion chamber of the furnace; wet fuel is introduced into the upper portion of the shaft while a portion of the hot products of combustion gases from the upper portion of the combustion chamber are also permitted to flow into the upper portion of the shaft. The hot gases evaporate moisture from the fuel and are simultaneously cooled thereby so as to increase in density and fall by gravity within the shaft co-currently with the fuel for recirculation into the lower portion of the combustion chamber while the at least partially dried fuel is deflected from the bottom of the shaft into the lower portion of the combustion chamber along with the recirculated gases.
