Abstract
A fluidized bed reactor and a method of operating same in which three discrete chambers are formed in a housing and a main fluidized bed containing particulate fuel and adsorbent material is established in a first chamber. The fluidizing air in the first chamber entrains a portion of the particulate material as it passes through the bed and the first chamber. A portion of the particulate material that is entrained by the air is separated and introduced to additional grid means disposed in a second chamber to establish a bed of the separated particulate material. Air and a cooling fluid are passed through the bed of separated particulate material for cooling same. The cooled separated particulate material is passed to a third chamber for storage and the latter is connected to the main fluidized bed for selectively reinjecting the cooled separated particulate material back to the main fluidized bed. A portion of the separated particulate material may also be introduced to another fluidized bed operating under conditions to convert the calcium sulfide formed in the main bed to calcium sulfate.
