Fuel nozzle assembly for use in turbine engines and method of assembling same

摘要

A fuel nozzle for use with a turbine engine is provided. The fuel nozzle includes a housing (484) coupled to a combustor liner (252) defining a combustion chamber (234). The housing is at least partially positioned within an air plenum (250) and comprises an endwall (488) that at least partially defines the air plenum. The fuel nozzle includes a plurality of mixing tubes (528) extending through the housing for channeling a fuel to the combustion chamber, a cooling fluid plenum (504) at least partially defined within the housing by the housing endwall, and a plurality of apertures defined within the housing endwall for channeling a cooling fluid (515) from the cooling fluid plenum to the air plenum.
