  • Fluidized Bed Combustion FBC Boiler - boilersinfo.com

    " (FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers." In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass upward through the sand.

  • Why to prefer Fluidized bed combustion boilers ?:-

    Bubbling of sand bed is created with the help of fluidizing air of velocity 1.2-3.7 m/sec. Coal of size 0-10mmis spread over bed (typically 1-6 mm size for under bed firing and 6-10mm for overbed firing), as soon as it reaches bed combustion takes place. In bed tubes are used in AFBC boiler

    The circulating fluidized bed (CFB) boiler (see Figure 8) takes the principle of the bubbling bed one step further and with increased fluidization velocity the particles are lifted out of the bed and follow the gas out of the combustion chamber. They are then separated from the gas in a cyclone or beam separator and returned to the bed.

    BFBC Boiler Design Principles • Bubbling bed boilers are short and stocky because. O The low heat release rates make the plan area large. O A residence time of 2.0-2.5 s makes the freeboard only —6 m, even for larger boilers. • With nearly 60-70% of evaporation taking place in the bed coils, the boiler bank load is greatly reduced.
