In the present investigation a cylindrical electrostatic precipitator was built into a cyclone's outlet tubes, and was tested at various dusts and voltages. It has been found that the penetration (the unremoved fraction of the dust) for the airborne particles (d < 10 mm) in the case of working built in electrostatic precipitator, decreased to 5–10% of the penetration of the (only) mechanical cyclone operation. The penetration data is given at various dusts and voltages. All are proving that the method is working satisfactorily. If the voltage was smaller than the on set voltage of the discharge, the better performance could be observed. It means that with electric field it is possible to utilize the tribo-charge of the dust particles caused by the collision with the wall of the cyclone.
