Abstract: A method, system and apparatus for a low bed pressure drop circulating fluidized bed (CFB) boiler associated with fast bed CFB combustion are disclosed. The CFB boiler may be operated according to the following set of conditions. In an upper area of a combustor of the boiler, a flow pattern of the two-phase gas-solid flow may be placed in a fast bed fluidization state. The combustor temperature may be within a range of 850° C.-930° C. The fluidizing air velocity may be within 4 m/s and 6.2 m/s. An average size of a bed material in the combustor may be smaller than 300 ?m. The gas-solid flow above of the secondary air inlet in the combustor may be kept in the fast bed fluidization state while maintaining a solid concentration of between 1 kg/m3 to 5 kg/m3. An inventory of bed material per unit area and/or the pressure drop in the combustor may be less than 8 kPa.
