  • Patent number: 9464574
    Abstract: A method for running up a stationary gas turbine is provided. The turbine has a combustion chamber, the burners of which have a pilot burner and a main burner and by which various types of fuel are introduced into the combustion chamber for burning. The method, carried out while a rotor of the gas turbine is accelerating from a standstill to a nominal speed, includes feeding fuel of a first type of fuel to the pilot burners and feeding fuel of the first type of fuel to the main burners. In order to provide a method in which a comparatively low supply pressure is required in the fuel supply system and in which combustion vibrations that put the machine at risk are avoided during the running-up process, it is proposed that fuel of a second type of fuel is fed to the burner before the nominal speed is reached.

  • Publication number: 20130247578
    Abstract: A method of operating a gas turbine, a device for regulating the starting and/or the operation of a gas turbine and a power plant are provided. The method includes continuously extracting fuel from a fuel network, and combusting, in at least one combustion chamber of a gas turbine, the fuel by adding combustion air. For an increase of a fuel stream supplied to the at least one combustion chamber, a fuel volume is extracted from a fuel store and supplied to the fuel still to be supplied to the at least one combustion chamber.
