    Fluidized Bed Boiler - an overview | ScienceDirect Topics

    4.5.2 Fluidized-bed firing. In fluidized-bed boilers a bed, usually consisting of sand particles, is brought into a fluidized state by primary air supplied from below the bed. Solid fuel added to the bed will burn in the oxygen-rich conditions inside the bed created by the primary air.

    How Circulating Fluidized Bed Boilers Work? - Bright Hub

    Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.

    The Circulating fluidized bed coal fired boiler contains mainly particles of an inert material, like sand and ash, including particles of SO2 sorbent. The coal content in a fluidized bed is not considerable, it is only from 3 to 5% of the whole mass of the bed. CFB boilers are touted for their fuel flexibility.

    COAL-FIRED POWER PLANTS:FLUIDIZED BED COMBUSTION

    While the pulverized coal-fired boiler represents the most efficient type of coal- fired power plant, there are alternatives. One of these is the fluidized bed boiler. This type of combustion system is capable of burning a much wider range of fuels than a PC plant. It operates at a lower temperature, making the production of nitrogen oxide less of a problem, and it can also incorporate sulfur capture within the …

    Fluidized Bed Combustion (FBC Boiler) “Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.” A bed of solid particles is said to be fluidized when the pressurized fluid (liquid or gas) is passed through the medium and causes the solid particles to behave like a fluid under certain conditions.

      As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm.
