CYLINDER FOR COMBUSTOR, COMBUSTOR, AND GAS TURBINE

WIPO Patent Application WO/2022/181694

A1

A cylinder for combustion (20) comprises a barrel (21) that forms a cylindrical shape, and an air supply pipe (40). An insertion opening (25) and a plurality of cooling flow paths (30) are formed in the barrel (21). A part of the air supply pipe is inserted into an inner circumferential side of the barrel from the insertion opening. Collision region flow paths (33i), which are some of the plurality of cooling flow paths, each have a collision region circumvention flow path part (34i). The collision region circumvention flow path parts intersect with a collision gas axis (Ai) that extends in the direction of the flow of, among combustion gas, combustion gas that moves toward a pipe center axis (At) of the air supply pipe. Moreover, the collision region circumvention flow path parts extend in a direction having an upstream-side direction component from the collision gas axis along the edge of the insertion opening, and extend in a direction having a downstream-side direction component from the collision gas axis along the edge of the insertion opening. Within each of the collision region circumvention flow path parts, an exit is not formed in a portion within the range of specified angles about the pipe center axis, said angles being centered on the collision gas axis.
