WHEEL CHAMBER CASING AND GAS TURBINE

摘要

A valve (6) for supplying external air to the inside of an upper wheel chamber casing (5a), and while the operation of an gas turbine is stopped, the valve introduces external air from the upper wheel chamber casing (5a) to the inside of a wheel chamber casing (5). When the external air is introduced from the upper wheel chamber casing (5a), the upper wheel chamber casing (5a) is cooled to prevent heat deformation of the wheel chamber casing (5).
