A fluidized bed furnace (10) is provided having a perforate grate (9) within a housing which supports a bed of particulate material including some combustibles. The grate is divided into a plurality of segments (E2-E6, SH1-SH5, RH1-RH5), with the airflow to each segment being independently controlled.

  • Coal Bottom Ash/Boiler Slag - Material Description -

    The most common type of coal-burning furnace in the electric utility industry is the dry, bottom pulverized coal boiler. When pulverized coal is burned in a dry, bottom boiler, about 80 percent of the unburned material or ash is entrained in the flue gas and is captured and recovered as fly ash.

    In the first designs of FBC boilers the inert bed material was in bubbling fluidization regime. The inert bed material particles are in intensive chaotic motion, but the bed as a whole remains immobile and stationary. This type of boiler is called the stationary bubbling FBC boiler (BFBC), or increasingly more common first generation FBC boilers.
