  • Patent number: 9605564
    Abstract: The invention relates to a method for operating a steam power plant, particularly a combined cycle power plant, which includes a gas turbine an a steam/water cycle with a heat recovery steam generator, through which the exhaust gases of the gas turbine flow, a water-cooled condenser, a feedwater pump and a steam turbine. A cooling water pump is provided for pumping cooling water through said water-cooled condenser. Evacuating means are connected to the water-cooled condenser for evacuating at least said water-cooled condenser. The method relates to a shut down and start-up of the power plant after the shutdown.

  • Patent number: 9581049
    Abstract: The invention relates to a warming arrangement having a warming system for warming a steam turbine. The warming system has a makeup line and recycle line fluidly connected to the steam turbine. A gas moving device and a heater are located in either of these two lines. The warming system further includes a pressure measurement device that is configured and arranged to determine a gauge pressure in the steam turbine as well as a controller. The controller is configured to control a flow rate of the warming gas through the steam turbine, based on the pressure measurement device.

  • Patent number: 9523503
    Abstract: A combustion device (10) includes at least one combustion chamber (11) with a plurality of burners (B1, . . . , Bn) operating in parallel which produce in each case a flame (F1, . . . , Fn) which reaches into the combustion chamber (11), wherein each of the burners (B1, . . . , Bn), via a fuel distribution system (18), is supplied with a fuel from a fuel supply (16), which fuel distribution system (18) includes control elements (V1, . . . , Vm) for manual or controlled regulating of the fuel supply and/or fuel composition of individual burners (B1, . . . , Bn) and/or groups of burners (B1, . . . , B3; Bn?2, . . . , Bn). In a method of using the combustion device, a quick optimization or homogenization is achieved by a function (F) of the flame temperatures of the burners (B1, . . . , Bn) being provided in dependence upon the positions of the control elements (V1, . . .

  • Patent number: 8454297
    Abstract: A method for determining the remaining service life of a rotor of a thermally loaded turboengine in which a temperature on the rotor is determined. Thermal stress on the rotor is calculated from the determined temperature, and the remaining service life of the rotor is calculated from the derived thermal stress. The temperature is measured directly at a predetermined point of the rotor, and the thermal stress on the rotor is derived from the measured temperature.

  • Publication number: 20100296918
    Abstract: A method is provided for determining the remaining service life of a rotor of a thermally loaded turboengine. In the method, a temperature on the rotor is determined, the thermal stress on the rotor is derived from the determined temperature, and the remaining service life of the rotor is deduced from the derived thermal stress. A simple, exact and flexible determination of the remaining service life is achieved in that the temperature is measured directly at a predetermined point of the rotor, and in that the thermal stress on the rotor is derived from the measured temperature.
