Fluidized bed reactor having a furnace strip-air system and method for reducing heat content and increasing combustion efficiency of drained furnace solids

摘要

A fluidized bed reactor having a furnace strip-air system and method for reducing heat content and increasing combustion efficiency of drained furnace solids in which a bed of particulate material is supported in a furnace section. A portion of the bed receives a greater amount of fluidizing gas to increase the stoichiometric conditions in the bed portion, strip relatively fine material from the particulate material in the bed portion and increase the amount of heat transferred to the flue gases. A cooler is located adjacent the furnace section for receiving particulate material from the bed portion.
