摘要： A bundled tube fuel injector includes an outer band that circumferentially surrounds a fuel plenum defined within the bundled tube fuel injector. The outer band includes a forward end portion that is axially separated from an aft end portion. A plurality of pre-mix tubes extends through the fuel plenum substantially parallel to one another. A first segment of the plurality of pre-mix tubes is circumferentially surrounded by the outer band. An outer shroud extends circumferentially around a second segment of the pre-mix tubes. The outer shroud includes a forward portion and an aft portion. The aft end portion of the outer band is coupled to the forward portion of the outer shroud via a plurality of fasteners for enhanced assembly and reparability.

摘要： 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.

摘要： A fuel injection head for use in a fuel injection nozzle comprises a monolithic body portion comprising an upstream face, an opposite downstream face, and a peripheral wall extending therebetween. A plurality of pre-mix tubes are integrally formed with and extend axially through the body portion. Each of the pre-mix tubes comprises an inlet adjacent the upstream face, an outlet adjacent the downstream face, and a channel extending between the inlet and the outlet. Each pre-mix tube also includes at least one fuel injector that at least partially extends outward from an exterior surface of the pre-mix tube, wherein the fuel injector is integrally formed with the pre-mix tube and is configured to facilitate fuel flow between the body portion and the channel.
