METHOD AND APPARATUS FOR FUEL NOZZLE ASSEMBLY FOR USE WITH COMBUSTOR

摘要

PROBLEM TO BE SOLVED: To provide a fuel nozzle assembly (126) for use with a combustor (124).SOLUTION: A fuel nozzle assembly includes a fuel nozzle (236) including a discharge end. A cap (206) including an outer surface (304) is coupled adjacent to the nozzle discharge end. At least one dampener mechanism (208) is coupled to the cap outer surface to facilitate reducing vibrations induced to the fuel nozzle. Moreover, a method for assembling a combustor assembly includes: a step of coupling the cap (206) adjacent to the discharge end of the fuel nozzle (236); a step of coupling at least one dampener mechanism (208) to the cap; and a step of positioning the fuel nozzle in the combustor assembly so that the at least one dampener mechanism facilitates reducing vibrations induced to the fuel nozzle during the operation of the combustor.
