<P>PROBLEM TO BE SOLVED: To maintain the temperature that generated flames themselves have around the flames. <P>SOLUTION: An injection flame burner 1 comprises a plurality of injection nozzles 5 of a double structure which comprises an outer tube 3 and an inner tube 4 coaxial with the outer tube 3 and in which either of the outer tube 3 and inner tube 4 injects hydrogen gas and the other injects oxygen gas; and positions injection holes 6 of the injection nozzles 5 in an injection surface. The injection nozzles 5 include at least one main injection nozzle 5a having an inner tube 4a flared toward the injection surface, and other sub injection nozzles 5b arranged around the main injection nozzle 5a. The gas injected from the inner tube 4a of the main injection nozzle 5a is injected in a higher pressure condition than the gas injected from the sub injection nozzles 5b. <P>COPYRIGHT: (C)2007,JPO&INPIT |
