Abstract
Method and apparatus for reducing NOx production during air-oxygen-fuel combustion by providing a central core of fuel surrounded by a sheath of oxygen at a combustion end of an air-oxygen-fuel burner. Diametrically opposed air passages are provided on either side of the oxygen sheath to permit entrainment of furnace gases into a flame zone created by primary combustion of fuel and oxygen. Oxygen can be introduced into each air passage to enhance combustion with low NOx emissions.
