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.
