A FLUIDIFIED BREAD REACTOR WITH A AIR SEPARATION SYSTEM, IN THE FURNACE, AND A PROCESS FOR REDUCING THE HEAT CONTENT AND INCREASING THE COMBUSTION PERFORMANCE OF THE DRIED SOLIDS IN THE FURNACE

摘要

A fluidized bed reactor (10) in which a bed of particulate material (25) is supported in a furnace section. A portion (25b) 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 (40) is located adjacent the furnace section for receiving particulate material from the bed portion. IMAGE
