Circulating Fluidised Bed Boiler

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.

Fluidized bed combustion - Wikipedia

2019-11-11 · Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.

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. The overall efficiency of an electric utility power plant should be increased by at least 1
