BED IN A LARGE-VOLUME SPHERICAL PACKING

An experimental study has been made of the motion of a 
circulating fluidized bed in a column filled with a large-volume spherical 
packing. It has been established that, once the feed of the loose 
material ceases, the motion of the bed continues up to the total removal 
of the disperse medium from the column with a velocity acquired in 
constant circulation. A procedure based on the processing of experimental 
results has been proposed for calculation of the operating conditions 
of apparatuses in which the indicated motion can be employed.
