  • Steam turbine system for a power plant
    Publication number: 20110146279
    Abstract: A steam turbine system for a power generating plant is provided. The steam turbine in the system has a live steam control valve at its live steam inlet, an extraction steam outlet, a live steam bypass line with a throttle valve which is connected to the inlet of the live steam control valve and also to the extraction steam outlet for directing live steam, which is throttled with the throttle valve, from upstream of the live steam control valve to the extraction steam outlet. The steam turbine with the live steam control valve and the live steam bypass line with the throttle valve are designed such that the steam turbine can be operated both in the nominal operating state with 100% live steam mass flow and in a special operating state with live steam mass flow above 100%, with a fully open live steam control valve in each case.
