ABSTRACT:
A circulating fluidized bed boiler having improved reactant utilization. The circulating fluidized bed boiler includes a circulating fluidized bed having a dense bed portion and a lower furnace portion above the dense bed portion. At least one secondary air and recirculated flue gas injection device is downstream of the circulating fluidized bed for providing mixing of the reactant and the flue gas in the furnace above the dense bed. The present invention also includes methods of operating a fluidized bed boiler.
