Abstract: A stream of hot oxygen is formed by providing a duct and a fuel lance movable axially within the duct, flowing gaseous fuel out of the lance into the duct, mixing it in the duct with gaseous oxidant, flowing the mixture out of the duct into an atmosphere which is hot enough that it ignites the mixture without aid of an ignition source other than said atmosphere, and combusting said mixture in a flame that does not extend into said duct; then moving the lance so its fuel outlet approaches the duct exit orifice so that the base of said flame moves inside said duct to the fuel outlet; and then moving the lance to draw the fuel outlet and the flame attached thereto away from the exit orifice into the duct; and increasing the flow rate of gaseous oxidant in said duct, so that combustion of fuel within the duct heats uncombusted oxygen which emerges as a stream of hot oxidant.

Abstract translation: 通过提供在管道内轴向移动的管道和燃料喷枪来形成热氧流，将气体燃料从喷枪流出到管道中，将其与气体氧化剂混合在管道中，将混合物从管道中流出到 足够高的气氛，使得在没有辅助除了所述气氛之外的点火源的情况下点燃混合物，并且在不延伸到所述管道中的火焰中燃烧所述混合物; 然后移动喷枪使其燃料出口接近管道出口孔，使得所述火焰的底部在所述管道内移动到燃料出口; 然后移动喷枪以将燃料出口和附接到其上的火焰从出口喷射到管道中; 并且增加所述管道中的气态氧化剂的流速，使得管道内燃料的燃烧加热作为热氧化剂流出现的未燃氧。

Abstract: A stream of hot oxygen is formed by providing a duct (3) and a fuel lance (7) movable axially within the duct, flowing gaseous fuel out of the lance into the duct, mixing it in the duct with gaseous oxidant, flowing the mixture out of the duct into an atmosphere which is hot enough that it ignites the mixture without aid of an ignition source other than said atmosphere, and combusting said mixture in a flame that does not extend into said duct; then moving the lance so its fuel outlet (9) approaches the duct exit orifice (5) so that the base of said flame moves inside said duct to the fuel outlet; and then moving the lance to draw the fuel outlet and the flame attached thereto away from the exit orifice into the duct; and increasing the flow rate of gaseous oxidant in said duct, so that combustion of fuel within the duct heats uncombusted oxygen which emerges as a stream of hot oxidant.
