Provided are a combustor nozzle, a gas turbine combustor, a gas turbine, a cover ring, and a combustor nozzle manufacturing method. The combustor nozzle includes: a nozzle body provided with a fuel flow passage; a cover ring that is disposed on an outer side of the nozzle body so as to form air flow passages that allow air to jet out toward a front side; and fuel injection nozzles that are provided in a leading end part of the nozzle body at predetermined intervals in a circumferential direction and extend through the cover ring so as to be able to inject fuel from the fuel flow passage toward the front side. The cover ring has an outer circumferential surface cover that covers an outer circumferential surface of the nozzle body, a leading end surface cover that covers a leading end surface of the nozzle body, and a plurality of inclined flow passages that extend through the leading end surface cover in a thickness direction and are inclined in a predetermined direction relative to a direction of a central axis.

Combustor nozzle, gas turbine combustor, gas turbine, cover ring, and combustor nozzle manufacturing method

A cylinder for a combustor includes a cylindrical member, a first cooling passage defined in the cylindrical member and a second cooling passage defined in the cylindrical member, and a supply port extender. The first cooling passage includes a supply port that opens to an outer peripheral surface of the cylindrical member. The second cooling passage includes a discharge port that opens to the outer peripheral surface of the cylindrical member downstream of the supply port. The supply port extender includes a first wall that is disposed between the supply port and the discharge port and extends away from the outer peripheral surface of the cylindrical member and a second wall that is disposed upstream of the supply port and extends away from the outer peripheral surface of the cylindrical member.

Cylinder for combustor, combustor, and gas turbine

A pilot nozzle, a gas turbine combustor and a gas turbine are provided with a nozzle main body having a fuel passage, a cover ring arranged at an outside of a front end-outer peripheral portion of the nozzle main body at a predetermined interval to form an inner air passage and capable of injecting air toward a front side of the nozzle main body, a plurality of nozzle tips that includes a fuel injection nozzle attached to a front end portion of the cover ring at a predetermined interval in a circumferential direction to communicate with the fuel passage and is able to inject fuel toward an outside of injection air from the inner air passage, and a swirling force application unit that applies a swirling force to air injected through the inner air passage.
