Abstract: 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.

Abstract: An oxyburner (1) is associated with an opening (3) comprising a through passage (2) comprising a substantially cylindrical inlet region (5) receiving the downstream end of the oxyburner (1) and a substantially cylindrical outlet region (4) of a diameter D.sub.s and a length L.sub.s, the ratio D.sub.s /D.sub.e being comprised between 1.5 and 2.5 and the ratio L.sub.s /(D.sub.s -D.sub.e) comprised between 2 and 7. The speed of ejection of the oxygenated combustible gas is greater than 5 meters/second and the speed of ejection of the combustible gas is greater than the speed of the combustion-supporting gas.
