  • Patent number: 11326471
    Abstract: A system for warming a power generation system including a boiler and a mixer fluidly coupled to the boiler, a turbine first section operable to receive steam from the boiler at a first temperature. The turbine supplies steam at a second temperature to a first heat exchanger operably connected to receive the heated steam at the second temperature from the output of at least the first section of the turbine and transfer heat to at least one of water and steam in the boiler or the mixer, feedwater for the boiler, and a thermal energy storage system. The system further includes a control unit configured to receive the monitored operating characteristic and control the amount of steam directed through the turbine.
    Type: Grant

  • Patent number: 11125118
    Abstract: A system for reheating a power generation system including a boiler and a mixer fluidly coupled to the boiler, a turbine first section operable to receive steam from the boiler at a first temperature. The turbine supplies steam at a second temperature to the boiler or mixer. The system also includes a first flow control valve operable to control a flow of steam through the turbine, and a sensor the sensor operable to monitor at least one operating characteristic in the boiler system. The system further includes a control unit configured to receive the monitored operating characteristic and control at least the first flow control valve, to control the amount of steam directed through the turbine.

  • 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.
