Abstract
A process for low NOX incineration which involves incinerating hazardous waste to produce a gaseous stream, adding combustible material to produce a combustible gas stream having combustible material in excess of the oxygen in the combustible gas stream, incinerating the combustible gas stream in a reducing atmosphere to produce a heated oxygen-depleted gaseous stream, converting at least a portion of the heat in the oxygen depleted stream into steam, adding air to the oxygen depleted stream to produce a stoichiometric excess of oxygen in the resultant stream relative to combustible material present in the resultant stream, passing the resultant stream over an oxidizing catalyst to produce an oxidized gaseous stream, removing heat from the oxidized stream, and venting the resultant cooled stream. A system for carrying out the foregoing process is also provided.
