Fluidized Bed Boilers Video - Convergence Training

Circulating fluidized bed boilers disperse particles throughout the furnace for improved heat transfer. The solids are removed from the flue gas and returned to the combustion zone. In a bubbling bed boiler, primary combustion air is forced through nozzles in the bottom of the boiler at a velocity high enough to fluidize the solid particles in
