COMBUSTOR ASSEMBLY FOR USE IN TURBINE ENGINE AND METHOD OF ASSEMBLING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a combustor assembly for use in a turbine engine.SOLUTION: A fuel nozzle assembly (34) for use with the turbine engine (10) is described herein. The fuel nozzle assembly (34) includes a plurality of fuel nozzles (38) positioned within an air plenum defined by a casing (44). Each of the plurality of fuel nozzles is coupled to a combustion liner (54) defining a combustion chamber. Each of the plurality of fuel nozzles includes a housing (84) that includes an inner surface (96) that defines a cooling fluid plenum (106) and a fuel plenum (104) therein, and a plurality of mixing tubes (128) extending through the housing. Each of the mixing tubes includes an inner surface (134) defining a flow channel (136) extending between the air plenum and the combustion chamber. At least one mixing tube of the plurality of mixing tubes includes at least one cooling fluid aperture (150) for channeling a flow of cooling fluid from the cooling fluid plenum to the flow channel.
