Abstract
A method and apparatus for the more complete incineration of dangerous waste gases to produce by-products which are safer for eventual release into the atmosphere. The invention involves mixing the waste gases with a flammable co-incineration fuel at an upstream location which is devoid of a combustion-supporting atmosphere, moving the mixture downstream to an ignitor fuel flame, and introducing a source of oxygen immediately downstream of the flame to support the combustion of the flame. The flame ignites the co-incineration fuel which, together with the flame, co-incinerates the waste gases in an area between the upstream area at which the waste and fuel gases are mixed and the downstream area at which the source of oxygen is admitted. The invention also preferably includes centering the co-incineration reaction for 'cold wall' operation, mixing the by-products with air for cooling purposes.
