Abstract
A gas turbine combustor includes a plurality of narrowing parts that protrude toward the inside of a combustion liner. The center axis of the combustion liner includes an upstream center axis, which linearly extends in an upstream region of the combustion liner, and extends in an ejection part in a direction that is different from the extension direction of the upstream center axis. The combustion liner includes a first region and a second region, the first region and the second region being divided by a virtual plane which includes the center axis from the upstream region to the ejection part, and the virtual plane is orthogonal to a virtual flat plane that includes the center axis. A straight line obtained by extending the upstream center axis passes through the first region in the ejection part. The total value of projected 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 projected areas of the narrowing parts present in the first region as viewed from the extension direction of the center axis.
