Hot part of gas turbine, gas turbine including the same, and manufacturing method of hot part of gas turbine

摘要

A hot part (450) of a gas turbine includes a planar member having a gas path surface (451) that faces at least one of an inner side and an outer side in a radial direction of the rotor in a combustion gas flow path. A cooling flow path is formed in an interior of the planar member along an outer peripheral surface (452) that intersects the gas path surface (451). The planar member has an outer peripheral surface side turbulator (482) that protrudes from an inner surface on an outer peripheral surface (452) side of the cooling flow path.

1. A hot part of a gas turbine that defines a ring-shaped combustion gas flow path around a rotor, the combustion gas flow path having combustion gas flowing therethrough, the hot part comprising:
a planar member that includes a gas path surface, the gas path surface facing at least one of an inner side and an outer side in a radial direction of the rotor in the combustion gas flow path, wherein the planar member includes a cooling flow path that is formed in an interior of the planar member along an outer peripheral surface that intersects the gas path surface, and an outer peripheral surface side turbulator that protrudes from an inner surface on the outer peripheral surface side of the cooling flow path, and wherein the hot part further comprises a gas path surface side turbulator that protrudes from an inner surface on the gas path surface side of the cooling flow path.
