Fluidized bed combustion boilers - energypurse.com

The circulating fluidized bed (CFB) boiler (see Figure 8) takes the principle of the bubbling bed one step further and with increased fluidization velocity the particles are lifted out of the bed and follow the gas out of the combustion chamber. They are then separated from the gas in a cyclone or beam separator and returned to the bed.

Fourth generation circulating fluidized bed boiler

The bed material is composed of sand, fuel ash, and some sulfur capturing material. Sulfur dioxide removal from flue gas during the combustion process is possible, for example, by adding limestone in the bed, which is considered to be one of the most important advantages of fluidized bed combustion . The mixture of bed material is fluidized by the primary combustion air brought in from the bottom of the
