ABSTRACT:
A process and apparatus for oxygen-enriched combustion of a fuel in an industrial furnace in which a preheated primary oxidant from a heat exchanger and a fuel to be combusted are introduced into a combustion chamber and ignited, a secondary oxidant having an oxygen concentration in excess of the concentration of oxygen in air is introduced into the combustion chamber downstream of the flame, and the resulting combustion products are exhausted. In accordance with one embodiment, the secondary oxidant comprises preheated oxidant aspirated from the heat exchanger using industrial-grade oxygen, resulting in an oxygen-enriched mixture being injected into the combustion chamber downstream of the flame. As a result, NO.sub.x emissions are reduced without adverse effects on the overall furnace operation.
