    • PROBLEM TO BE SOLVED: To provide a high-temperature burner for industrial melting furnace, having satisfactory fuel efficiency, NOx characteristic and the like. SOLUTION: The burner includes separate fuel and oxidant conduits. The cross sectional flow area of a fuel transitional section 18 varies from an initial cross sectional flow area at a fuel intake 14 to a different cross sectional flow area at a fuel outtake 22, and the cross sectional flow area of a fuel outlet section 20 is substantially uniform. At least some of an oxidant inlet section 26 is spaced around substantially all of at least a portion of at least one of the fuel inlet section 16, the transitional section 18, and the outlet section 20. The cross sectional flow area of an oxidant outlet section 30 is less than or equal to the cross sectional flow area of the oxidant inlet section 26 and is substantially uniform, and at least some of it is spaced around substantially all of at least a portion of the fuel outlet section 20.
