FUEL NOZZLE ASSEMBLY USED IN TURBINE ENGINE AND ASSEMBLY METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a fuel nozzle (236) to be used together with a turbine engine (100).SOLUTION: A fuel nozzle includes a housing (484) that is connected to a combustor liner (252) for defining a combustion chamber (234). The housing includes an end wall (488) that is at least partially positioned in an air plenum (250), and at least partially defines the air plenum. The fuel nozzle includes: a plurality of mixing tubes (528) that are extended through the housing for guiding the fuel to the combustion chamber; a coolant plenum (504) that is at least partially defined in the housing by the end wall of the housing; and a plurality of holes (602) which are defined in the end wall of the housing for guiding coolant (515) from the coolant plenum to the air plenum.
