Why to prefer Fluidized bed combustion boilers ?:-

Circulating (fast )fluidized bed combustion system are designed to overcome drawbacks associated with AFBC boiler. Fluidizing velocity in this type of boiler is relatively very high 3.7-9m/sec, The combustion takes place at 840-900 °C, and the fine particles (<450 microns) are elutriated out of the furnace with flue gas velocity of 4–6 m/s.

Heat transfer in a large-scale circulating fluidized bed

Abstract. Heat transfer of a furnace in a large-scale circulating fluidized bed (CFB) boiler was studied based on the analysis of available heat transfer coefficient data from typical industrial CFB boilers and measured data from a 12 MW e, a 50 MW e and a 135 MW e CFB boiler. The heat transfer of heat exchanger surfaces in a furnace, in a steam/water cooled cyclone, in an external heat

Technology Overview: Circulating Fluidized-Bed

A circulating bed boiler should not exceed a conventional atmospheric fluidized-bed combustor in capital coat, and will probably be less, due to reduced combustor size. The cost advantage of a pressurized circulating bed boiler is questionable. 2.
