  • Patent number: 10527056
    Abstract: A method for repairing a blade connection of a generator rotor is disclosed. The generator rotor includes an internally threaded hole formed in the generator rotor and an externally threaded blade root. The method includes the steps of removing the blade from the generator rotor, removing material of a first section of the root extending from an end of the root closest to the airfoil, and screwing the blade back into the threaded hole. Additionally, a reworked blade and a reworked blade generator rotor connection is disclosed.

  • Publication number: 20190254123
    Abstract: The present invention relates to an induction cooking hob (10) comprising at least one cooking zone (12) including one induction coil (14). The induction cooking hob (10) comprises at least one user interface (22) including at least one display with at least one indicator corresponding with one cooking zone (12, 28, 30, 32). The induction coil (34, 36, 38, 40) is provided for detecting at least one parameter related to the power of the electromagnetic field generated by said induction coil (34, 36, 38, 40). The induction cooking hob (10) comprises a memory for storing a maximum value of the parameter detected by the induction coil (14) of the cooking zone (12) when a cooking pot (26) is arranged upon said cooking zone (12). The indicator corresponding with the cooking zone (12) indicates a signal related to an incorrect position of the cooking pot (26), if the currently detected value of the parameter is lower than the maximum value of said parameter.

  • Publication number: 20170045228
    Abstract: A gas turbine with a sequential combustor arrangement as disclosed includes a first combustor with a first burner for admitting a first fuel into a combustor inlet gas during operation and a first combustion chamber for burning the first fuel, a dilution gas admixer for admixing a dilution gas to the first combustor combustion products leaving the first combustion chamber, a second burner for admixing a second fuel and a second combustion chamber. To assure a temperature profile after the dilution gas admixer and to increase the gas turbine's power and efficiency a vane and/or blade of the turbine has a closed loop cooling. The outlet of the closed loop cooling is connected to the dilution gas admixer for admixing the heated cooling gas leaving the vane and/or blade into the first combustor combustion products.

  • Patent number: 7562532
    Abstract: A gas turbine group comprises a device, arranged in a suction-intake duct, for cooling a suction-intake airflow. The device is, for example, a device for injecting a liquid mass flow. The cooling device is activated automatically when a first limit temperature of the ambient air is overshot and is deactivated automatically when a second limit temperature is undershot. Stability of the automatic algorithm can be improved in that the second limit temperature can lie by a specific amount below the first limit temperature. In one embodiment, the limit temperatures are predetermined as a function of the position of an adjustable initial guide blade cascade.
