摘要： Improved methods and burner apparatus are provided for discharging mixtures of fuel and air into furnace spaces wherein said mixtures are burned and flue gases having low NO.sub.x content are formed therefrom. The methods basically comprise discharging a first fuel mixture containing a portion of the fuel and flue gases from the furnace space into the furnace space whereby the mixture is burned in a primary reaction zone therein and flue gases having low NO.sub.x content are formed therefrom, and then discharging the remaining portion of the fuel into a secondary reaction zone wherein the remaining portion of fuel mixes with air and flue gases to form a second fuel mixture which is burned in the secondary reaction zone and additional flue gases having low NO.sub.x content are formed therefrom.

摘要： 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 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： Improved low NO.sub.x formation gas burner apparatus and methods of burninguel are provided. The burner apparatus includes a refractory burner tile having a base portion and a wall portion, the wall portion extending into the furnace, surrounding a central area of the base portion and having exterior sides which are slanted. Means 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 of the burner tile. At least one secondary fuel gas nozzle means positioned for discharging the remaining portion of the fuel gas adjacent to an external slanted side 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.
