Abstract

An injection flame burner in which temperature of the generated flame itself can be sustained around the flame. A plurality of double structure injection nozzles each consisting of an outer tube and an inner tube provided coaxially with the outer tube, are arranged such that hydrogen gas is ejected from one of the outer tubes and the inner tubes and oxygen gas is ejected from the other tubes, and the injection port of each injection nozzle is located on the injection surface. Each injection nozzle includes at least one main injection nozzle having an inner tube formed to spread toward the injection surface side, and another sub-injection nozzle arranged around the main injection nozzle, wherein gas is injected from the inner tube of the main injection nozzle under a higher pressure state as compared with gas injected from the sub-injection nozzle.
