  • Patent number: 10167742
    Abstract: A steam cycle for a power station, and to a method for operating, in particular for starting, a steam cycle. The steam cycle has a high-pressure turbine, a condenser and a steam generator. The steam generator is connected to the high-pressure turbine via a first line. Live steam quick-closing valves and live steam regulating valves for supplying the high-pressure turbine are arranged in the direction of the steam flow between the steam generator and the high-pressure turbine. A starting line is arranged downstream of the high-pressure turbine in the direction of the steam flow, the starting line connecting a waste steam region downstream of the high-pressure turbine with the condenser. At least one regulator regulates a closing of a starting valve for sealing the starting line, and an opening of the live steam valve, depending on the rotational speed, a temperature and load state of the high-pressure turbine.

  • Publication number: 20150121871
    Abstract: A turbine plant (3), in particular a steam turbine plant, and a method (100) for cooling the turbine plant (3). The turbine plant (3) has a turbine (29) through which a process gas (15) flows in a flow direction (27) during operation. A cooling medium (7) is drawn or blown (120) through the turbine (29) either in or counter to the process gas flow direction (27) respectively, cooling the turbine (29). A fan (6) may be coupled to either a turbine inlet (4) or to a turbine outlet (5). The fan acts on the cooling medium (7, 110) which is drawn into the turbine (29) through the turbine inlet (4) or through the turbine outlet (5) to be blown (120) through the turbine (29) in or counter to the process gas flow direction (27).

  • Patent number: 8857455
    Abstract: A method for regulating a steam bypass valve is provided. The bypass valve is arranged in a steam line and the steam line includes a device for spraying water. The equation, t Rest , 0 = FB max m . W , SOLL - m . W , IST is used to determine when to close the steam bypass valve. The steam bypass value is closed when tRest,0 is smaller than a value ?t. An actual volume of water {dot over (m)}W,IST, a desired volume of water {dot over (m)}W,SOLL and a maximum water-volume deficiency FBmax are used in the equation.
