  • Coaxial dual supersonic speed oxygen flow coherent oxygen lance
    Patent number: 12065708
    Abstract: A coaxial dual supersonic oxygen flow cluster oxygen lance comprises an inner layer circular-hole supersonic nozzle assembly, an outer layer water-cooled casting assembly, and a middle layer annular-hole supersonic nozzle assembly arranged between the inner layer circular-hole supersonic nozzle assembly and the outer layer water-cooled casting assembly, wherein the circular-hole supersonic assembly generates a first beam of supersonic oxygen jets and the annular-hole supersonic assembly generates a second beam of supersonic oxygen jets surrounding the first beam of supersonic oxygen jets; and the second beam of supersonic oxygen jets and the first beam of supersonic oxygen jets are in the same direction, and the two beams of supersonic oxygen jets are independently supplied with gas, and are independently adjusted.
