Circulating Fluidized Bed (CFB) Coal Fired Steam Boilers

Circulating Fluidized Bed (CFB) Coal Fired Steam Boilers. Heavier particles collected by the separator are sent into the main combustion chamber via the recycle device to "recycle" and burn again. Light smoke enters into end heating surface of boiler and continues to provide heat for the drum. Advanced combustion technology enables the thermal efficiency of this kind of boiler can reach over 86%.

Fluidized Bed Boiler - an overview | ScienceDirect Topics

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.
