摘要： Improved gas burner apparatus and methods of burning fuel gas-air mixtures are provided whereby flue gases having low NO X contents are formed. The burner apparatus includes a refractory burner tile (30) having an air discharge opening (34) therein and a wall (36) surrounding the opening which extends into the furnace space and provides a mixing zone therein. At least one passage (54) 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 therethrough 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.

摘要： A radiant gas burner which includes a refractory burner tile (12) having an elongate passageway (28) extending therethrough and a fuel-air mixture burner tube (34) disposed within the passageway. The burner tube is of a one-piece elongate construction, includes a nozzle portion (40,42) at the interior end of the passageway and is connected to a manifold block (38) by a threaded connection positioned adjacent the exterior end of the passageway. Secondary fuel is discharged from the passageway at a location (86,88) adjacent the nozzle portion of the burner tube.

摘要： Improved low NO x formation gas burner apparatus and method in which the burner apparatus includes a refractory burner tile (30) having a base portion (32) and a wall portion (34), the wall portion extending into the furnace, surrounding a central area (40) of the base portion and having external sides (43) which are slanted. Means (48) are attached to the burner tile for mixing a portion of the fuel gas with the air and discharging the resulting mixture into a primary burning zone in the furnace from within the space defined by the wall portion (34) of the burner tile. At least one secondary fuel gas nozzle (70) positioned for discharging the remaining portion of the fuel gas adjacent to an external slanted side (43) of the wall portion whereby the fuel gas mixes with flue gases and air in the furnace and burns in a secondary burning zone therein.
