    • A fuel injector (310) for a combustor (300) of a gas turbine engine (100) is disclosed. The fuel injector (310) includes a flange (312), a fitting boss (315), a stem (320), a gas fuel passage (322), a gas fuel fitting (317), and a gas heat shield (380). The fitting boss (315) protrudes from the flange (312). The stem (320) extends from the flange (312). The gas fuel passage (322) extends through the stem (320). The gas fuel fitting (317) is joined to the fitting boss (315). The gas heat shield (380) extends from the gas fuel fitting (317) at least partially through the gas fuel passage (322). The gas heat shield (380) is sized to form a gas heat shield gap (389) between the gas heat shield (380) and the stem (320) at the gas fuel passage (322).
    • 公开了一种用于燃气涡轮发动机(100)的燃烧器(300)的燃料喷射器(310)。 燃料喷射器(310)包括凸缘(312),配件凸台(315),杆(320),气体燃料通道(322),气体燃料配件(317)和气体隔热罩(380) 。 装配凸台315从凸缘312突出。 杆(320)从凸缘(312)延伸。 气体燃料通道(322)延伸通过杆(320)。 气体燃料配件(317)连接到配件凸台(315)。 气体热屏蔽(380)至少部分地通过气体燃料通道(322)从气体燃料配件(317)延伸。 气体隔热罩(380)的尺寸被设计成在气体燃料通道(322)处在气体隔热罩(380)和阀杆(320)之间形成气体隔热间隙(389)。
