Fluidized Bed Combustion. FBC enables the capture of acidic pollutants without resorting to scrubbers, although as with pulverized coal combustion, both bottom ash and fly ash are formed the lower combustion temperature, and the presence of the sorbent in the ash results in a product with substantially different properties.
Mar 04, 2020 · The evaporator tubes of boiler are directly immersed in the fluidized bed and the tubes, being in direct contact with the burning coal particles, produce very high heat transfer rates. Because of this, the unit size is reduced to a great extent, and also produces combustion with very high efficiency.
