Abstract
Methods of servicing a fuel nozzle are provided. a method of servicing a fuel nozzle includes a step of machining away material from a nozzle tip of the fuel nozzle to form an annular groove within the nozzle tip. The method further includes a step of inserting a replacement coupon into the annular groove. The replacement coupon having a radially outermost that corresponds to the annular groove and a post-removal contact surface. The method further includes a step of fixedly coupling the radially outermost of the replacement coupon to the annular groove.
Claims19
A method of servicing a fuel nozzle of a combustor, the fuel nozzle having a forward end coupled to the combustor and extending to a nozzle tip at an aft end, the method comprising:
- forming an annular groove in the nozzle tip by machining away material from the nozzle tip;
- inserting a replacement coupon into the annular groove, the replacement coupon having a radially outermost surface that corresponds to the annular groove and a post-removal contact surface;
- fixedly coupling the radially outermost surface of the replacement coupon to the annular groove.
A fuel nozzle for a combustor, comprising:
- a flange disposed at a forward end of the fuel nozzle, the flange coupled to the combustor;
- a nozzle tip disposed at an aft end of the fuel nozzle, the nozzle tip defining an aft face and an annular groove;
- a replacement coupon positioned within the annular groove, the replacement coupon having a radially outermost surface that is fixedly coupled to the annular groove such that a fixed connection line is defined on the aft face of the nozzle tip.
