    摘要: A combustor cylinder includes a cylinder, and a fuel nozzle capable of injecting fuel into a combustion space of the cylinder. The cylinder has a plurality of cooling passages allowing cooling air to circulate therethrough, and a nozzle attachment penetration hole penetrating the cylinder from an outer circumferential surface of the cylinder to an inner circumferential surface of the cylinder. The fuel nozzle has a mixing passage, a fuel passage communicating with the mixing passage and capable of supplying the fuel to the inside of the mixing passage, and a connection passage communicating with the mixing passage and capable of supplying cooling air from a part of the plurality of cooling passages to the inside of the mixing passage. A position in the mixing passage communicating with the connection passage is on a side where a spout port of the mixing passage is present from a position where the mixing passage communicates with the fuel passage.

    摘要: A fuel injector includes: a flat tube disposed over an aperture of a wall of a combustor that extends toward a turbine in a gas turbine system. The flat tube is configured such that air compressed by a compressor of the gas turbine system flows perpendicular to a thickness direction of the flat tube before flowing through the aperture. The flat tube has a fuel hole through which gaseous fuel that flows inside the flat tube exits to a passage of the air. An entire length of a downstream edge of the flat tube with respect to a flow of the air is disposed within the aperture when viewed perpendicular to the wall.
