Characterization of gas-solid fluidization with large-particle

By a series of cold-model test, characterization of gas-solid fluidization with large-particle is researched, because the kind of fluidization may be used to calcinations process in producing cement. It has shown that gas-solid fluidized bed with large-particle is stable in bubbling regime and liable to slugging fluidization, so it had better be operated in shallow fluidized bed and low operating fluidizing number. It has known by analysis of pressure drop fluctuation that quality of fluidization can be improved with wider size distribution particle.
