  • Combined fluidized bed calciner and pulverized coal boiler and method of operation
    Patent number: 4622904
    Abstract: A fluidized bed calciner cooperating with a pulverized coal boiler includes a two tier fluidized lime cooling bed arrangement. Control of the combustion air flow through the fluidized bed calciner by means of a bypass achieves flexible operation and economy. The cooling beds transfer heat from the hot lime to the combustion air, and a bypass controls the temperature of the air flowing to the combustion chamber. The two tier arrangement is compact and adaptable to the retrofitting of a standardized pulverized coal boiler.
