Circulating Fluidized Bed Boiler CFB Industrial Boiler

Circulating Fluidized Bed Boiler evolved from efforts in Germany to control emissions from roasting sulfate ores without the need for external emission controls (such as scrubbers-flue gas desulfurization). The mixing action of the fluidized bed brings the flue gases into contact with a sulfur-absorbing chemical, such as limestone or dolomite.

Fluidized bed boilers, boilers with a fluidized bed

2019-7-28 · Fluidized bed boilers. Fluidized bed boilers use the principle of burning fuels in a fluidized bed. A fluidized bed creates conditions suitable for the uniform combustion of fuel throughout its volume, which means, as a final result, more perfect fuel burn-up (high efficiency of a fluidized bed boiler) at lower combustion temperatures and whilst reducing the production of harmful waste gases
