燃料喷嘴总成、燃料喷嘴模块以及燃气轮机
摘要：
本发明涉及燃料喷嘴总成和包含燃料喷嘴总成的燃料喷嘴模块以及燃气轮机。燃料喷嘴总成包括：燃料喷嘴，向燃烧室供应燃料；护罩，与燃料喷嘴相隔，围绕燃料喷嘴，并在内壁和燃料喷嘴之间形成流路；轮圈，沿着护罩入口的外周缘形成，将空气引导至流路中；转向导向器，配置为与轮圈相隔，对要流入到流路中的空气的流动进行分配。转向导向器包括：转向隔板，与轮圈相隔，沿着轮圈的圆周方向延长形成，并对轮圈的一部分进行包裹；一对内隔板，沿着轮圈的直径方向延长，对转向隔板的圆周方向上的端部和燃料喷嘴的外表面进行连接，并配置在圆周方向上的各个端部。根据本发明，能够防止气穴的生成并均匀地供应要流入到燃料喷嘴中的空气。
摘要（英）：

Disclosed are a fuel nozzle assembly, and a fuel nozzle module and gas turbine having the same. The fuel nozzle assembly includes a fuel nozzle for supplying fuel for a combustor, a shroud spaced apart from the fuel nozzle and defining a flow path between an inner wall and the fuel nozzle, a rim formed around the shroud to guide air to the flow path, and a turning guide spaced apart from the rim to distribute the air to flow into the flow path. The turning guide includes a turning separator spaced apart from the rim to extend in a circumferential direction of the rim, and inner separators extending in a radial direction of the rim to interconnect opposite circumferential ends of the turning separator and an outer surface of the fuel nozzle. The fuel nozzle assembly prevents air pockets, and ensures uniform supply of air flowing to the fuel nozzle.
