An incinerator generally including a combustion chamber, a flue and an apparatus intercommunicating the combustion chamber and the flue, for removing solid and gaseous contaminants from the combustion gases emanating from the combustion chamber and discharged through the flue into the atmosphere, the apparatus comprising a first stage separator defining at least one cylindrical chamber having a tangentially disposed inlet communicating with the combustion chamber, an outlet longitduinally spaced from the inlet and means for applying a film of liquid-washing medium on the interior wall thereof, and a second stage separator defining at least one cylindrical chamber having a tangentially disposed inlet communicating with the outlet of the first mentioned chamber, an outlet longitudinally spaced from the inlet thereof and communicating with the flue, means for applying a film of liquid-washing medium on the interior wall thereof and means for producing an electrostatic field between a locus with the chamber and the interior wall thereof, of sufficient strength to produce a corona discharge for ionizing solid and gaseous contaminants contained in the gases traversing therethrough whereby the contaminants will be subjected to combined centrifugal, electrostatic and gravitational forces to cause the contaminants to be diverted into contact with the film of liquid-washing medium and be removed therewith.
