    Circulating fluidized bed - Wikipedia

    As a result, the demand for circulating fluidized bed technology is predicted to rise. In 1923, Winkler's coal gasifier represented the first significant large-scale industrial application of fluidized bed (Kunii and Levenspiel, 1991). CFB combustion technology continues to grow strongly in large utility power plant applications as CFB boiler

    The History of the Steam-Generating Boiler and Industry

    The fluidized bed boiler uses a process by which solid fuels are suspended in an upward-flowing gas or air stream at the bottom of the unit. The burning fuel exists in a fluid-like state that has a high heat transfer but with lower reduced emissions.

    Coal - Wikipedia

    Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

    Fluidized bed combustion (FBC): In a FBC boiler, pulverized coal (and other fuels) is suspended on jets of pressurized air. FBC boilers typically allow the fuels to stay inside the boiler much longer than other boilers, which ensures more complete combustion. Also, FBC boiler temperatures are far lower than conventional
