抄録

The conditions for stable fluidization of continuously operated, multi-stage fluidized beds were studied.<BR>The performance in each stage of the multi-stage fluidized bed was found to be not markedly different from that of a single-stage fluidized bed in the region of stable fluidization.<BR>An empirical dimensionless equation for the relations among the geometry of the perforated plate, the properties of fluidized particles and the operating conditions is proposed for this region.<BR>It was found that the particles were discharged intermittently from a hole in the distributor, that the mass and frequency of discharge were inversely proportional to the superficial gas velocity, and that the former was proportional to the hold-up of particles within the bed.
