A method and apparatus for repressing NOx formation in twinned regenerative burner pairs includes inducing a stream of hot flue gas, preferably containing enriched products of combustion, from the main hot flue gas exhaust stream and vitiating the preheated combustion air with the hot flue gas in the firing burner. An interconnecting duct communicating with the twinned burner pair includes a coaxial gas nozzle for injecting a high kinetic energy gas stream into the exhausting hot flue gas to induce a portion of the hot flue gas into the interconnecting duct to pass the hot flue gas to the firing burner for vitiation purposes.

A method of repressing NOx formation in a regenerative type burner operably connected to a furnace comprising the step of: heating a regenerative bed with hot flue gas withdrawn from the furnace; preheating a combustion air stream in the heated regenerative bed; passing the preheated combustion air

A method of repressing NOx formation in a regenerative type burner operably connected to a furnace comprising the step of: heating a regenerative bed with hot flue gas withdrawn from the furnace; preheating a combustion air stream in the heated regenerative bed; passing the preheated combustion air stream to said burner; withdrawing a portion of hot flue gas from the furnace and passing said portion to said burner; and vitiating the preheated combustion air stream with said hot flue gas.
