摘要： 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 μm. 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.

摘要： The present invention relates to a partitioned jetting fluidized bed with double nozzles, especially to a jetting fluidized-bed reactor with gas distributor, where a inclined nozzle is fixed at the side wall of the jetting fluidized bed above the gas distributor, and the gas pre-distribution chamber with gas distributor consists of a gas pre-distribution chamber with combined gas distributor and a gas pre-distribution chamber with perforated distributor. The two gas pre-distribution chambers are separated by a partition plate. The present invention can not only avoid the local agglomeration of the particles and the operation termination accident, but also broadens the adjustable range of the jet gas velocity and the distributor fluidization velocity. The excellent particle circulation can be reached in this jetting fluidized bed.
