ON THE CLUSTER STRUCTURE OF A CIRCULATING FLUIDIZED BED

Yu. S. Teplitskii

UDC 533.6

A model of a bottom fluidized bed has been developed, 
in which the latter is represented as an ensemble of uniformly distributed 
spherical clusters. Using Ergun's formula, we obtained the dependence 
for calculating the diameter of a cluster. The results were compared 
with experimental data on the sizes of clusters in the transport zone 
of a circulating fluidized bed. In the framework of this model, a 
correlation to calculate the rate of filtration at which the bottom 
layer disappears has been obtained.
