THE ELUTRIATION RATE FROM A PACKED FLUIDIZED BED

[摘要] References(6)Cited-By(3)The particle elutriation rate from a packed fluidized bed consisting of particles of almost uniform size is measured for various reduced bed heights, Lmf/LT various reduced gas velocities U/UT, and various packing sizes. An experimental equation for that rate is obtained. The elutriation rate of fine particles from a packed fluidized bed comprising particles of two sizes is also measured under various experimental conditions. That rate is proportional to the concentration of fine particles in the bed. An experimental equation for the elutriation rate constant is obtained Finally, the mechanism of elutriation from the packed fluidized bed is discussed.
