US8069825B1 - Circulating fluidized bed boiler having

A method of operating a furnace having a circulating fluidized bed is described. Fuel is combusted in the fluidized bed. The fluidized bed includes a dense bed portion and a lower furnace portion adjacent to the dense bed portion. Reactant is injected in the furnace to reduce the emission of at least one combustion product in the flue gas.

Circulating Fluidized Bed Combustion - an overview

In circulating fluidized bed combustion (CFBC) (Fig. 5), the gas velocity is higher than in FBC, and a large part of the solid particles is carried over from the bed into a tall riser, where the particles aggregate into clusters that reflux at the wall. Particles that are carried over from the riser are precipitated by a high-temperature process cyclone and are recirculated into the riser.
