  • Patent number: 8925321
    Abstract: A steam power plant is provided. The steam power plant includes a bypass pipeline which connects the fresh steam line flow to the exhaust steam line, wherein a bypass steam cooler is disposed in the bypass pipeline. In the event of an emergency stop, or a startup, or a shutdown, the bypass steam cooler cools the steam flowing into the bypass pipeline, whereby cheaper materials may be used for the bypass pipeline.

  • Patent number: 6305398
    Abstract: A method for heating a valve configuration of a steam turbine, includes the steps of directing steam to a closed valve of the valve configuration, condensing the steam in the valve, and discharging the condensate. The temperature is kept at the saturated-steam temperature corresponding to the respective steam pressure. The method is in particular suited for keeping a bypass-valve configuration hot. The bypass-valve configuration is intended for bypassing the steam turbine on the steam side. For this purpose, a steam line is connected to the valve configuration. The steam line has an inclined line section with a rising slope or a falling slope directly upstream of the valve configuration. A valve configuration for a steam turbine is also provided.
