摘要： A combustor for a gas turbine, includes: a first fuel nozzle group and a second fuel nozzle group each of which includes a fuel nozzle capable of supplying a fuel and has an independently controllable fuel supply system; a cylinder inside which a combustion region allowing a combustion gas produced by combustion of the fuel to flow is formed; and a first contraction portion extending partially along a circumferential direction so as to correspond to one of the first fuel nozzle group or the second fuel nozzle group and protruding radially inward from an inner peripheral surface of the cylinder.

摘要： An acoustic damper of the present invention is objected to obtain a sound absorption effect of a combustor in an extensive range of frequency band. The acoustic damper includes an acoustic pipe body attached to a combustor so as to communicate with an inside of the combustor, and the acoustic pipe body is provided with a plurality of passages whose extension lengths are different from each other inside the acoustic pipe body.

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.

摘要： A combustor according to the invention includes a combustor basket to which air A is supplied from the outside, a plurality of first nozzles that are annularly provided along the inner periphery of the combustor basket and that supply premixed gas M of the air and fuel to the inside of the combustor basket, and a transition piece in which the combustor basket is connected to a base end thereof and which burns the premixed gas supplied from the first nozzles, thereby forming a flame front spread to the outer periphery side toward the leading end in an axial direction, wherein each first nozzle supplies the premixed gas with fuel concentration changed around the center axis of the first nozzle such that the flame front has a uniform temperature in the axial direction.

摘要： A combustor includes a combustor external cylinder, a tubular combustor basket installed in the combustor external cylinder, a compressed air channel defined between the combustor external cylinder and the combustor basket, and a plurality of fuel nozzles installed in the combustor basket. Compressed air flowing along the compressed air channel is approximately reversed in the flow direction at an end of the combustor basket, and is introduced into the plurality of fuel nozzles. Fuel injection pegs made up of an upstream side fuel injection peg injecting upstream side fuel and a downstream side fuel injection peg injecting downstream side fuel, are installed in the compressed air channel. Concentration fluctuation of the upstream side fuel caused by pressure fluctuation in the combustor is configured so as to reduce a peak of concentration fluctuation of the downstream side fuel at a combustion start position of the combustor.
