FLUIDIZED BED COMBUSTION Fluidized bed combustion (FBC) is a combustion technology used in power plants. FBC plants are more flexible than conventional plants in that they can be fired on coal and biomass, among other fuels. Fluidized beds suspend solid fuels on upward-blowing jets of air during the combustion process.

combustion. In pulverized coal systems, combustion is almost complete; thus, the emitted PM is primarily composed of inorganic ash residues. Coal ash may either settle out in the boiler (bottom ash) or entrained in the flue gas (fly ash). The distribution of ash between the bottom ash and fly ash fractions directly affects the PM emission rate
The heart of a coal-fired power plant is a boiler, in which coal is burned by combustion to turn water into steam. The following equation shows what burning coal looks like chemically: C + O 2--> CO 2.Coal isn't made of pure carbon, but of carbon bound to many other elements.

Fossil fuel fired electric generating plants are the cornerstone of America's central power system. Currently, the existing fossil fuel fleet accounts for about two-thirds of all electricity generated domestically, over 30% from coal alone. Electricity demand is expected to increase dramatically over the next 30 years with the growth of the manufacturing sectors.
