Abstract

From a number of studies in gas-solids cyclone separators which have been reported in literature, it is shown that, developing more efficient cyclone separators have been essentially based on experiments rather than mathematical models. One of the main performance characteristics of the gas-solids cyclone separators is the collection efficiency. The principle object of this work is to study experimentally the effect of some of the major controlling parameters that have direct effect on the cyclone performance, essentially on the gas-solids cyclone separators collection efficiency. These parameters are the cyclone size, properties of solid phase and air inlet velocity. The results obtained showed that collection efficiency increases with increasing the particle size, inlet velocity and the maximum efficiency was occur at 10 cm cyclone diameter.
