A combustor of the present disclosure includes a combustor plate configured to have a downstream end face perpendicular to a combustor axis; a nozzle segment configured such that a plurality of first nozzles that inject a premixed gas of air and fuel from a side of the downstream end face are collectively disposed; and a plurality of second nozzles configured to inject the fuel from the downstream end face. A plurality of the nozzles segments are provided at intervals in a direction perpendicular to the combustor axis. Each of the second nozzles injects the fuel from a dividing region between the nozzle segments on the downstream end face.

Combustor and gas turbine

A high-temperature part of the present disclosure includes: a high-temperature part body which includes a base and a coating layer formed on a part of a surface of the base; and a protective layer which is formed on at least a part of a surface of the coating layer. The protective layer is formed of a material which is allowed to disappear from a surface of the coating layer under an operation environment of a gas turbine.

A fuel injector has a body extending in an axial direction. The body includes: an axial passage formed so as to extend in the axial direction; a radial passage formed so as to communicate at one end with the axial passage and to open at another end to an outer surface of the body; and an internal passage including a first opening and a second opening open to the outer surface, and formed so as to extend inside the body from the first opening to the second opening. The first opening and the second opening are located opposite to each other across a third opening, through which the radial passage opens to the outer surface, in a circumferential direction centered on an axis of the body.

Fuel injector, combustor including the fuel injector, and gas turbine including the combustor

A combustor includes: a tube plate having an upstream side end face and a downstream side end face that are orthogonal to a combustor axis, in which an air hole passing through the upstream side end face and the downstream side end face is formed in the tube plate; and a fuel injector that injects fuel into air passing through the air hole. The air hole has: a bent channel that curves toward a direction orthogonal to the combustor axis toward the downstream side; and an inclined channel that is connected to the downstream side of the bent channel so as to be continuous therewith, and that extends inclining with respect to the combustor axis and opens to the downstream side end face. A fuel injection position at which the fuel injector injects fuel is located on the downstream side of the upstream end of the bent channel.

An outlet seal connects a combustor that combusts a fuel to generate combustion gas and a shroud for a stator. The outlet seal has a gas path surface, a first connection section, and a second connection section. The shape of the gas path surface in a cross section perpendicular to an axis is an arc centered on the axis. The first connection section is formed at a first side in an axial direction and is connected to the combustor. The second connection section is formed at a second side in the axial direction and is connected to the shroud. The gas path surface has an inclined surface that is inclined with respect to the axis in a cross section including the axis, such that the flow-path area of a combustion-gas flow path is reduced toward the second side.

A fuel control device includes a stem fuel valve opening degree determination unit, a branch line flow rate determination unit, and a correction value determination unit. The stem fuel valve opening degree determination unit is configured to determine an opening degree of a flow rate adjustment valve of a stem fuel supply line. The branch line flow rate determination unit is configured to determine an opening degree of a flow rate adjustment valve of at least one branch line. The correction value determination unit is configured to determine a correction value of the opening degree of the flow rate adjustment valve of the at least one branch line based on a value of a pressure difference between a fuel pressure upstream of a nozzle connected to the at least one branch line and a corrected fuel pressure for a fuel pressure at an outlet.

A resonant sound absorbing device of a gas turbine combustor includes a plurality of resonance chambers independently disposed side by side in an axial direction of the gas turbine combustor so as to communicate with a gas passage of the gas turbine combustor via acoustic holes. The plurality of resonance chambers include n related resonance chambers each satisfying: where n is an integer of 2 or more, and Fi is a peak frequency corresponding to a maximum sound absorbing ratio of the ith related resonance chamber of the n related resonance chambers.

To provide a damping device that includes an acoustic liner that forms an acoustic-liner resonant space along an outer periphery of a combustion chamber in which a combustion gas flows, and an acoustic damper provided on an outer peripheral side of the acoustic liner, to form an acoustic-damper resonant space that communicates with the acoustic-liner resonant space. The acoustic liner is formed with a damper opening connected with the acoustic damper for causing the acoustic-liner resonant space and the acoustic-damper resonant space to communicate with each other. The acoustic liner includes a divided portion that is a portion to be divided in a circumferential direction of the combustion chamber by the damper opening, and a continuous portion that is a portion continuous over the circumferential direction of the combustion chamber.

It is possible to achieve self-support of the fuel assembly without an upper grid plate when the fuel assembly is mounted or replaced, and it is also possible to prevent the fuel assembly from floating during a reactor operation. According to the present invention, the lower portion of the lower tie plateas a part of the fuel assembly, which is inserted into the fuel support, extends, and a stable memberis provided around the extension portion, and thereby it is possible to achieve the self-support of the fuel assembly without the upper grid plate. In addition, since an increase in a weight due to extension of the lower portion of the lower tie platecan prevent the floating during the reactor operation, a floating preventing mechanism using the upper grid plate is not necessary. Hence, it is possible to achieve the self-support of the fuel assembly without an upper grid plate when the fuel assembly is mounted or replaced, and it is also possible to prevent the fuel assembly from floating during the reactor operation.
