Abstract: Pollution control apparatus and a method for removing particulate matter from a gas at temperatures of up to about 3000.degree. F. are disclosed comprising a gas centrifuge having effluent and influent openings and a spray nozzle positioned to inject a stream of a refrigerated fluid at the effluent gas passing through the centrifuge. The spray nozzle is arranged to force particulate matter against the walls of the gas centrifuge in order to facilitate removal of particles in the gas stream and also to cool the gas to a low temperature after which it may be either discharged into the atmosphere or processed through a moving filter at low temperatures to further remove any finer particles in the gas passing through the apparatus. The lower temperatures of the gas emanating from the gas centrifuge allow the use of a cloth or synthetic fiber filter such as a Dacron (trademark) filter.
