Gas turbine, fuel supply system and fuel supply method

The invention discloses a gas turbine, a fuel supply system and a fuel supply method, and relates to the technical field of gas turbines. The fuel supply system comprises a fuel pipeline used for conveying fuel; the fuel supply module is communicated with the fuel pipeline; the fuel supply module at least comprises a gas fuel supply device and a liquid fuel supply device; and the variable resistance module is arranged on the fuel pipeline and is used for adjusting the flow resistance of fluid in the fuel pipeline. The gas fuel supply device and the liquid fuel supply device not only can share the fuel pipeline, but also can realize fuel switching under the non-stop condition. In other words, different types of fuel can be conveyed through the same fuel pipeline, the complexity of the fuel supply system is reduced, and the reliability of the fuel supply system is improved. 本申请公开了一种燃气轮机、燃料供给系统及其方法，涉及燃气轮机技术领域。该燃料供给系统包括：燃料管路，用于输送燃料；与所述燃料管路相连通的燃料供给模块；所述燃料供给模块至少包括气体燃料供给装置和液体燃料供给装置；变阻模块，设置于所述燃料管路，用于调整所述燃料管路中流体的流动阻力。
