Title:
STEAM TURBINE PLANT AND METHOD FOR IMPROVING SAME
Document Type and Number:
WIPO Patent Application WO/2023/176155
Kind Code:
A1
Abstract:
This steam turbine plant is provided with: a steam turbine having a first ground seal provided on one side in an axial direction of a turbine rotor and a second ground seal provided on the other side in the axial direction thereof; and a gas extraction system including a gas extractor that extracts non-condensing gas of a condenser on a downstream side of the steam turbine. The first ground seal is connected only to a first discharge system for discharging gas flowing into the first ground seal, and the second ground seal is connected to a second discharge system for discharging gas flowing into the second ground seal. The first and second discharge systems are connected to the gas extraction system so that the gas flowing into the first and second ground seals is guided to the gas extractor without passing through the condenser.
