Patents by Inventor Ernst-Wilhelm Pfitzinger

Ernst-Wilhelm Pfitzinger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.
