Abstract

The powder-particle fluidized bed is a new type of fluidized bed proposed by the authors to treat fine particles (less than 20μm in diameter).<BR>Residence time distribution of fine particles in a powder-particle fluidized bed was measured. The effects of feed rate of the fine particles, gas velocity, diameters of the fine and coarse particles, and fluidized bed height on the residence time were investigated. The residence time increased as the size of the fines and gas velocity decreased, and as the bed height increased. The average residence time of fine particles was 150-500 times larger than that of gas in the bed. This fact suggests that adhesion of fine particles to the coarse particles occurs in the bed.
