Cooling device for cooling highly corrosive combustion gases

Abstract From the Canadian patent

A cooling device for use in the quenching of combustion gases containing hydrogen chloride. The entire quenching zone is lined with acidproof material as a safeguard against the occurrence of temperatures lower than the dew point wherever, they may occur inside the quenching zone. This temperature sensitive lining of the quenching zone is protected against the action of the hot combustion gases by a covering above the quenching liquid feed inlet, of heat-retaining bricks of differing thicknesses, which absorb and buffer the heat contained in the hot combustion gases. Further the quenching zone, is equipped, in its upper third portion with 3 to 8 nozzle, structures for the intake of cooling …
