EXHAUSTER OF GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To provide an exhauster of a gas turbine capable of preventing leakage of high pressure compressed air to a low pressure exhaust passage. SOLUTION: Airtightness between a turbine shroud and the exhaust passage is held by integrally fastening a ring elastic plate metal member on either of an end part of the turbine shroud forming an outer peripheral wall along a turbine blade of the rotating turbineand an exhaust passage end part facing against the end part of the turbine shroudand making the elastic plate metal member contact with the exhaust passage end part facing against it or the end part if the turbine shroud with pressure. The elastic plate metal member is formed in a bellows shape or constituted of a plate spring.
