<P>PROBLEM TO BE SOLVED: To make uniform injected fuel and air in a combustion burner. <P>SOLUTION: On the outer peripheral surface of a main nozzle 59, a plurality of swirlers 60 for swirling air flowing from the upstream side of the main nozzle 59 to the downstream side are arranged at predetermined intervals in a peripheral direction to form a fuel passage 72 in the main nozzle 59. On the other hand, cavities 73 are formed in the swirlers, the fuel passage 72 and the cavities 73 are communicated via three communication passages 74, 75, and 76, and fuel injection holes 77 and 78 for injecting fuel supplied to the cavities in the swirlers to the outside are formed. A swirling force applying unit is provided for applying swirling force to a fuel flow supplied from the fuel passage 72 through the communication paths 74, 75, and 76 to the cavities. <P>COPYRIGHT: (C)2012,JPO&INPIT |
