  • Publication number: 20220282640
    Abstract: A system includes a pump for conveying a flow medium, an arrangement for converting the flow medium from a liquid state into a gaseous state, a turbomachine for converting the thermal energy of the flow medium into mechanical work, a condenser for condensing the gaseous flow medium into a liquid state, with a cooling unit for cooling the liquid flow medium being arranged upstream of the pump in order to reduce the compression work.

  • Patent number: 8776520
    Abstract: A method for operating a steam power station is provided. The steam turbine power station includes at least one steam turbine and a process steam consumer, wherein a steam mass flow is subdivided into a first partial mass flow and a second partial mass. In a first operating state, the first partial mass flow is supplied to the steam turbine and the second partial mass flow is supplied to the process steam consumer. In a second operating state, at least part of the second partial mass flow is supplied to the steam turbine at least after the first turbine stages. A steam power station is also provided.

  • Publication number: 20140150431
    Abstract: A steam power plant includes a multi-stage steam turbine including a rotor and a flow duct formed from a plurality of stages, a boiler, and a first cooling medium supply. The first cooling medium supply opens out into the flow duct of the steam turbine downstream of an intermediate stage. The rotor comprises a first component and a second component. The second component is arranged downstream of the first component as viewed in the flow direction. The intermediate stage is arranged downstream of the first component.

  • Patent number: 8713941
    Abstract: A method for operating a multi-step steam turbine operating in high temperature conditions is provided. The rotor is embodied as a welded construction including a first component and a second component. A coolant is supplied to the steam turbine after an intermediate state when the steam turbine is in the light-load or no-load phase. As a result, the thermal loads in the outflow area of the steam turbine are reduced.

  • Patent number: 8387388
    Abstract: The invention relates to a method for increasing the steam mass flow of a high-pressure steam turbine of a steam power plant, particularly a steam power plant including reheating, during a start-up phase of the steam power plant, particularly also during an idle period of the steam power plant, wherein at least one electric consumer is connected upstream of a generator of the steam power plant before synchronization with a power supply grid. The invention further relates to a steam power plant, comprising a generator, a high-pressure steam turbine, and at least one electric consumer, which can also be connected during a start-up phase of the steam power plant, particularly also during an idle period of the steam power plant, in order to increase a steam mass flow of the high-pressure steam turbine before a synchronization process of the generator with a power supply grid.
