The effects of cyclone size, inlet velocity, and particle size on the pressure drop
across the gas -solids cyclone separator are presented experimentally. The
experiments were conducted at four different cyclone sizes Of 7.5,10,14 and
16mm, various particle sizes ranged from 70 to 510~ and various dust loading
varied from 50 to 350gram,,li&g,~. The results showed that the pressure drop
across the cyclone decreases with increasing the cyclone size and increased
considerable with increasing the inlet velocity. The results indicated that the
pressure drop is found to increase sharply with increasing the particle size from
75pm to 225~ and then increases gradually with particle size larger than 225~.
The study reported very interesting correlation not previously addressed and
represents an addition to knowledge which leads to the prediction of the actual
pressure drop of dusty air from tests on clean air
