A remote staged radiant wall furnace burner configuration includes placement of secondary fuel gas nozzles remote from radiant wall burners. This configuration brings about an increased mixing of secondary fuel with furnace flue gases. As a result, the temperature of the burning fuel gas is lowered and NO x formation is reduced.
