Steam turbine system and control system therefor

摘要

Steam turbine system and control system therefor are provided. In one embodiment, a steam turbine system includes an auxiliary turbine in fluid communication with an IP turbine via an auxiliary turbine inlet conduit branch of an IP exhaust conduit. A heat exchanger system may remove heat from an IP exhaust steam, and may add the removed heat to water flowing through a boiler feed-water conduit to a boiler of the steam turbine system.
