Separation of particulates from a gaseous stream in a reverse flow cyclone separator is enhanced through the incorporation of a corona producing electrode in the cyclonic separation zone whereby particulates are first charged by the corona current and are subsequently displaced from the gaseous stream by the electrostatic forces generated by the electrode.

A reverse flow cyclone separator comprising a first swirl-inducing raw gas inlet, a radially inwardly disposed exhaust duct, a cyclonic separation zone disposed in flow communication intermediate said raw gas inlet and said exhaust duct and a means for producing a corona discharge in said cyclonic separtion zone wherein said corona discharge producing means comprises an electrode disposed substantially coaxially in said exhaust duct and having a corona producing portion extending out of said duct inlet into said cyclonic separation zone and first electrical means to enable the formation of a corona discharge between said corona producing portion and a wall of said cyclonic separation zone and further comprising a second swirl inducing inlet for substantially contaminant free gaseous medium, said second inlet including an inlet structure defining an introduction zone disposed radially inwardly from said raw gas inlet and radially outwardly of the inlet of said exhaust duct and second electrical means for forming a voltage gradient between said inlet structure and said wall of said cyclonic separation zone.
