<P>PROBLEM TO BE SOLVED: To provide an improved secondary nozzle for a preferable gas turbine system which has a simple configuration, performs several functions and withstands permanent damage caused by flame holding. <P>SOLUTION: The nozzle 24 for a burner includes: a central body 76; a burner tube body 74 provided around the central body 76 and defining a fuel-air mixture passage 72 therebetween; and an outer periphery wall 78 provided around the burner tube body 74 and defining an airflow passage 80 therebetween. The nozzle 24 further includes a nozzle tip 100 connected to the central body 76. The nozzle tip 100 includes: a pilot fuel passage 90 configured to feed a flow of pilot fuel 92 to a combustion zone; and a plurality of transition passages 94. The plurality of transition passages 94 are configured to feed an airflow to be burned by the flow of the pilot fuel 92 in the combustion zone, and also configured to feed a flow of transition fuel 96 to the combustion zone. <P>COPYRIGHT: (C)2012,JPO&INPIT |
