    Effect of Bed Pressure Drop on Performance of a CFB Boiler

    The effect of bed pressure drop and bed inventory on the performances of a circulating fluidized bed (CFB) boiler was studied. By using the state specification design theory, the fluidization state of the gas−solids flow in the furnace of conventional CFB boilers was reconstructed to operate at a much lower bed pressure drop by reducing bed inventory and control bed quality. Through

    How Circulating Fluidized Bed Boilers Work? - Bright Hub

    Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air

    Application of ultra-low NOx emission control for CFB

    1. Introduction. Research shows that the CFB boilers have the innate advantages of low NOx emission compared to pulverized coal boilers. However, for classical CFB boilers, there are still tremendous challenges under the pressure of ultra-low emission standard (lower than 50 mg/Nm −3), which is proposed by Chinese government in 2014.A considerable number of CFB boilers had to add
