GAS TURBINE COMBUSTOR AND GAS TURBINE

WIPO Patent Application WO/2023/176570

A1

A gas turbine combustor according to at least one embodiment of the present disclosure comprises a plurality of narrowing parts that protrude toward the inside of a combustion cylinder. The center axis of the combustion cylinder includes an upstream center axis, which linearly extends in an upstream region of the combustion cylinder, and extends in an ejection part in a direction that is different from the extension direction of the upstream center axis. The combustion cylinder includes a first region and a second region that are divided by a virtual plane which includes the center axis from the upstream region to the ejection part and which is orthogonal to a virtual flat plane that includes the center axis from the upstream region to the ejection part. A straight line obtained by extending the upstream center axis passes through the first region in the ejection part. The total value of projection areas of the narrowing parts present in the second region as viewed from the extension direction of the center axis is larger than the total value of projection areas of the narrowing parts present in the first region as viewed from the extension direction of the center axis.
