【 摘 要 】

References(6)Cited-By(2)A recently developed method of gas combustion with circulating fluidized bed (CFB) is presented and discussed. The main area of study was the hydrodynamics of CFB equipped with an internal nozzle in the center of the riser. The paper describes the results of an experimental study of particle behavior in the system. Glass beads of 100 μm and FCC particles of 56 μm in diameter were employed as bed materials. It was possible to control particle hold-up by changing the ratio of the gas flow in the nozzle to the total gas flow (Qi/Q). Both the particle feed rate and the inflection point were varied with Qi/Q. In addition, the height of the inflection point was dependent on the nozzle height.
