Low NO[sub x] gas burner apparatus and methods
Improved gas burner apparatus and methods of burning fuel gas-air mixtures are provided whereby flue gases having low NO[sub x] contents are formed. The burner apparatus includes a refractory burner tile having an air discharge opening therein and a wall surrounding the opening which extends into the furnace space and provides a mixing zone therein. At least one passage is formed in the burner tile which opens into the mixing zone and fuel gas is jetted through the passage whereby flue gases are drawn there through and a fuel gas-flue gases mixture is discharged into the mixing zone. The fuel gas-flue gases mixture is swirled in the mixing zone and mixes with air therein, and the resulting mixture is discharged and burned in a primary reaction zone in the furnace space. 11 figs.
