Abstract
An improved burner for combustion of fuel gas with air in a manner to result in low NOx, the burner is generally circular and has a refractory tile and gas tips. The gas tips are spaced around the outer circumference of a generally circular passageway in the burner tile, each gas tip is positioned to cause the fuel gas to entrain furnace flue gas. Each gas tip has one or more ports, an ignition port and at least one firing port. The ignition port injects fuel through a passageway to the burner tile. The firing port injects fuel gas in the direction that is generally upward with respect to the pathway of the ignition port. This causes fuel gas to entrain combustion products from the flue gas, the resulting mixture of fuel gas and flue gas is directed out of the burner tile to mix with combustion air that is discharged through the burner tile.
