Open the CIPO recordAbstract From the Canadian patent
In order to avoid incrustation and an excessively strong thermal attack on the afterburning chamber the, exhaust gases which contain gaseous and solid constituents which are combustible are afterburned in a plurality of stages, which are connected in series. The rate at which oxygen is supplied to each stage is so controlled that part of the combustible constituents is afterburned in each stage. The gas which is about to enter each succeeding stage is cooled by injected water.
