Title: Exhaust purifier system

Abstract: A system for purifying heated exhaust gases discharged from an internal combustion engine, a furnace, or the like. The system includes a novel rotating finned tube heat exchanger of generally cylindrical configuration. The exchanger has a plurality of longitudinally extending conduits which direct the exhaust gases back and forth between opposite end chambers of the heat exchanger. The gases are additionally passed, as required depending upon the type of pollutants they contain, through a series of purification devices which may include a novel afterburner to rid the gases of entrained unburned fuel, one or more water bath devices to cleanse the gases, and a separator to removed unburned compounds.
