Abstract
To provide a fuel nozzle for a gas turbine combustor, offering favorable durability and strength reliability. In a fuel nozzle for a gas turbine combustor, jetting fuel into a combustion chamber of the gas turbine combustor, the fuel nozzle is metallurgically and integrally bonded with a base plate that supports the fuel nozzle, and an interface between the fuel nozzle and the base plate includes a surface in which bonding is performed by a fusion joint or a brazing joint and an inside part in which bonding is performed by pressure bonding.
Claims15
A fuel nozzle for a gas turbine combustor, the fuel nozzle jetting fuel into a combustion chamber of the gas turbine combustor,
- the fuel nozzle being metallurgically and integrally bonded with a base plate that supports the fuel nozzle,
- an interface between the fuel nozzle and the base plate including a surface in which bonding is performed by a fusion joint or a brazing joint and an inside part in which bonding is performed by pressure bonding.
A method for manufacturing a fuel nozzle for a gas turbine combustor, the method comprising:
- (a) fitting a fuel nozzle having an internal through hole into a through hole or a recess provided in a base plate;
- (b) bonding, by a fusion joint or a brazing joint, the fuel nozzle to the base plate in an interface therebetween on a surface of the base plate;
- and
- (c) following the step of (b), subjecting the fuel nozzle and the base plate to a pressure bonding process to thereby pressure bond the fuel nozzle and the base plate in the interface therebetween.
