<P>PROBLEM TO BE SOLVED: To provide a gas turbine capable of further improving efficiency by suppressing a rise in the temperature of internal air in a stationary blade outer cavity. <P>SOLUTION: In order to solve the problem, the gas turbine includes stationary blades held directly or indirectly via other stationary members on a casing, and the cavity communicating in a circumferential direction between the inner circumferential face of the casing and the outer circumferential faces of the stationary blades and shut off by the stationary blades and the other stationary members from a gas path in which fuel gas flows. In the gas turbine, a heat shield with a plurality of metal plates piled in a radial direction and air layers formed between the metal plates is installed near surfaces of the stationary blade outer circumferential faces in the cavity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
