STEAM TURBINE PLANT AND METHOD FOR IMPROVING SAME

Abstract: a steam turbine plant includes a steam turbine including a first gland seal provided on one side in an axial direction of a turbine rotor and a second gland seal provided on the other side in the axial direction of the turbine rotor and a gas extraction system including a gas extractor configured to extract noncondensable gas in a condenser on a downstream side of the steam turbine. only a first discharge system for discharging a gas flowing into the first gland seal is connected to the first gland seal, and a second discharge system for discharging a gas flowing into the second gland seal is connected to the second gland seal. the first and second discharge systems are connected to the gas extraction system so as to guide a gas flowing into the first and second gland seals to the gas extractor without passing through the condenser.
