An oxy-fuel burner according to the present invention includes an outer oxidant tube, an intermediate fuel tube and an inner oxidant tube which are coaxially arranged with the fuel tube disposed between the inner and outer oxidant tubes. Characteristics of the flame produced by the burner may be controlled by varying the relative flow rates of the inner and outer oxidant flows. An increase in the percentage of the total oxidant which is provided to the inner oxidant tube causes the length and luminosity of the flame to decrease and the flame momentum to increase. According to the present invention, the characteristics of a burner flame can be tailored to a particular application without requiring mechanical modification of the burner.

[ What is claimed is:] [1.] An oxy-fuel burner comprising an outer oxidant-conducting passage forming an outer oxidant outlet, an inner oxidant-conducting passage forming an inner oxidant outlet, oxidant source means for providing a source of oxidant comprising at least 80% oxygen, said oxidant source means being in fluid communication with said inner and outer oxidant-conducting passages, a fuel-conducting passage forming a fuel outlet, said outer oxidant outlet, said inner oxidant outlet, and said fuel outlet being coaxially arranged, with said fuel outlet disposed radially between said outer and inner oxidant outlets, and first valve means for varying a flow rate of oxidant through the inner oxidant-conducting passage to control a characteristic of the flame.
