<p><P>PROBLEM TO BE SOLVED: To provide an apparatus and a method for fuel nozzle frequency adjustment. <P>SOLUTION: A combustion liner cap assembly (30) includes a cylindrical outer sleeve (28) including a center fuel nozzle opening and a plurality of outer fuel nozzle openings (26) spaced around the center fuel nozzle opening. A mounting flange assembly (4) concentrically surrounds the cylindrical outer sleeve. A plurality of struts (24) on an outer surface of the cylindrical outer sleeve support the mounting flange assembly. A plurality of flanges (32) are on the outer surface of the cylindrical outer sleeve, and a plurality of support rods (20) having first ends (34) are adjustably supported by respective flanges. A combustor for a gas turbine includes a combustion liner cap assembly, a plurality of outer fuel nozzles supported in the plurality of outer fuel nozzle openings, and a center fuel nozzle supported in the center fuel nozzle opening. Second ends (36) of the plurality of support rods (20) adjustably contact the center fuel nozzle (2). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
