Experimental research regarding the influence of inlet geometry and air stream characteristics over separation efficiency

In this paperis presented the dependence of the efficiency of separation process for system such as solid-gas in the cyclone according to the geometrical characteristics of the inlet and outlet . The measurements were made on a laboratory pilot plant which permits the modification of cyclone inlet and outlet sections. The determination of the separation efficiency was made by comparing the quantity of material introduced in system and the quantity recovered in the cyclone collection bunker. During the experimental research it were also measured the speed and the temperature of the air stream and the pressure in different points of transport and separation route.
