Cylinder for combustor, combustor, and gas turbine

Abstract

A cylinder for a combustor, inside which combustion gas generated by combustion of fuel can circulate, includes a cylinder body extending along an axis line. The cylinder body has at least one cooling passage which is formed in a wall part of the cylinder body, which extends in the extension direction of the axis line, and in which a cooling fluid can circulate. The at least one cooling passage has: an inlet opening that is an inlet for the cooling fluid and that opens on a peripheral surface of the cylinder body; and an outlet opening that is an outlet for the cooling fluid and that opens on the peripheral surface of the cylinder body. The inlet opening and/or the outlet opening has a first dimension in the extension direction of the axis line greater than a second dimension in the circumferential direction of the cylinder body.
