EXHAUST CHAMBER INLET-SIDE MEMBER, EXHAUST CHAMBER, GAS TURBINE, AND LAST-STAGE TURBINE BLADE REMOVAL METHOD

摘要

An object of the present invention is to easily remove last-stage turbine blades. Provided is an exhaust chamber inlet-side member that has an annular shape around a rotor so as to form a part of an inner diffuser at a position facing, from the axially downstream side, base ends of last-stage turbine blades disposed on the most downstream side in the axial direction, and that is divided in the circumferential direction and provided so as to be detachable from the inner diffuser. When the exhaust chamber inlet-side member is dismounted from the inner diffuser, a space on the axially downstream side from the last-stage turbine blades is cleared.
