System and method for damping combustor nozzle vibrations

A system for damping combustor nozzle vibrations includes an end cover and a combustion chamber downstream from the end cover. First and second sets of nozzles (40, 42) extend axially between the end cover (14) and the combustion chamber. The second set of nozzles (42) is adjacent to the first set o...

Beschreibung
Zusammenfassung:	A system for damping combustor nozzle vibrations includes an end cover and a combustion chamber downstream from the end cover. First and second sets of nozzles (40, 42) extend axially between the end cover (14) and the combustion chamber. The second set of nozzles (42) is adjacent to the first set of nozzles (40). The system includes means (50) for damping vibrations between the nozzles (40, 42) with a gap (48) between the means for damping vibrations and the second set of nozzles (42). A method for damping combustor nozzle vibrations includes flowing a working fluid through first and second sets of nozzles (40, 42), wherein the first set of nozzles (40) includes a damping member (50) attached to and circumferentially surrounding at least a portion of the first set of nozzles (40), and contacting at least one nozzle in the second set of nozzles (42) with the damping member (50) on at least one nozzle (24) in the first set of nozzles (40).
