Patent number: 9464574Abstract: 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.Type: GrantFiled: July 25, 2012Date of Patent: October 11, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Eberhard Deuker, Berthold Kostlin, Jurgen Meisl, Dennis Nehlsen, Kai-Uwe Schildmacher
