  • Preservation method
    Patent number: 10895172
    Abstract: A power plant and method for preserving a power plant, the power plant having a steam turbine with a shaft, further including a condenser mounted downstream of the steam turbine in the direction of flow of the steam, a vacuum pump mounted downstream of the condenser, a compressed steam system with shaft seals, and a compressed steam supply line extending into the shaft seals; a first nitrogen line extends into the condenser, and a second nitrogen line as well as a recirculation line that branches off the vacuum pump extend into the compressed steam supply line.
    Type: Grant
    Filed: April 10, 2018
    Date of Patent: January 19, 2021
    Assignee: SIEMENS AKTIENGESELLSCHAFT
    Inventors: Uwe Juretzek, Michael Rziha, Edwin Gobrecht, Michael Schöttler

  • Measuring device for purity measurements in a media circuit of a power station and method for operating said measuring device
    Patent number: 8258794
    Abstract: A measuring device for carrying out purity measurements in a media circuit of a power station with an ion exchanger device and a measuring means for measuring a parameter of a media current flowing through the ion exchanger device is described. In order to obtain measurements in a rapid and reliable manner at the start up of the ion exchanger device, for example during the start-up phase of the power station, it is suggested that the ion exchanger device has two flow paths for two different operating modes of the power station.
