GAS TURBINE, SEALING DEVICE OF GAS TURBINE AND SEALING METHOD OF GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To provide a gas turbine with high reliability that enhances a leak performance, and is compatible with an offset of members affecting thermal elongation, and to a sealing device of gas turbine and a sealing method of gas turbine.;SOLUTION: In a gas turbine including a compressor, a combustor, and a turbine, component parts of the gas turbine are constructed as a plurality of segments, or divided construction, a seal groove is provided in a clearance surface of any one of segments, or in a clearance surface of any one of the divided construction, and a sealing device of the gas turbine with a seal plate attached to the seal groove is provided. The seal plate of the sealing device has a groove insertion portion for inserting into the seal groove, and a spring portion curved in a U shape, and has an area which is deformed by an elastic deformation of the spring portion when an external force is applied.;COPYRIGHT: (C)2009,JPO&INPIT
