ABSTRACT:
Apparatus for reburning ash material of a previously burned primary fuel includes a reburn combustion vessel having an inlet for receiving ash material from a primary combustion unit such as a boiler or furnace and an outlet for discharging the products of combustion from the vessel produced from burning the ash material. The outlet of the ash reburn vessel is connected to the primary combustion unit at an elevated height above the firing level. A floor is provided in the ash reburn vessel for supporting a discrete bubbling bed of burning ash material and the floor includes a plurality of spaced apart openings distributed relatively uniformly over substantially all of the area of the floor. Combustion air is introduced into the reburn vessel at a relatively low velocity to provide a source of underfire combustion air for the bubbling bed. Combustion air is also introduced at an upper level in the vessel above the bubbling bed to provide an overfire source of combustion for the upwardly moving unburned components of ash material carried along with the products of combustion rising out of the bubbling bed.
