Fuel supply system and gas turbine subassembly

The utility model provides a be used in the fuel supply system and gas turbine subassembly among the gas turbine engine. Wherein, fuel supply system includes fuel injector, technology fuel source, technology fuel source configure into guide technology fuel fluid to fuel injector flows, and secondary fuel source, the secondary fuel source configures the guide secondary fuel flow direction into fuelinjector flows. The secondary fuel flow with the mix of technology fuel fluid is higher than in order to form the calorific value the mixed starting fluid of technology fuel, and it is in to mix thestarting fluid follow between gas turbine engine's starting period fuel injector discharges. 本实用新型提供种用在燃气涡轮发动机中的燃料供给系统及燃气涡轮组件。其中，所述燃料供给系统包括燃料喷嘴；工艺燃料源，所述工艺燃料源配置成引导工艺燃料流向所述燃料喷嘴流动；以及二次燃料源，所述二次燃料源配置成引导二次燃料流向所述燃料喷嘴流动。所述二次燃料流与所述工艺燃料流混合以形成热值高于所述工艺燃料的混合启动燃料，并且所述混合启动燃料在所述燃气涡轮发动机的启动期间从所述燃料喷嘴排出。
