Title:
STEAM TURBINE INSTALLATION AND METHOD FOR OPERATING THE STEAM TURBINE INSTALLATION
Document Type and Number:
WIPO Patent Application WO/2013/007462
Kind Code:
A3
Abstract:
The invention relates to a steam turbine installation that has a steam turbine (5), a steam generator (2) and a feed water pre-heating unit (9-13, 17-21) operated by process steam, the steam turbine (5) having an overload bypass line (14) with which main steam can be fed to the feed water pre-heating unit (9-13, 17-21) between the steam turbine input and the extraction point (9) during overload operation of the steam turbine (5), characterised in that the feed water pre-heating unit (9-13, 17-21) has an auxiliary extraction line (17) that is connected to the overload bypass line (14) in such a way that process steam can be extracted from the steam turbine (5) during partial load operation of the steam turbine (5) and added to the feed water pre-heating unit (9-13, 17-21) for the additional pre-heating of feed water.
