  • Fluidized bed combustion - Wikipedia

    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. For instance, CFB coal fired boiler can efficiently use fuels such as low rank lignites and sub bituminous coals that typically produce a lot of ash and are difficult to use in other types of pulverized coal boilers. CFB boilers are even being used to remove gob …Learn More
