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. ## Claims ### Claim 1 A method for running up a stationary gas turbine having at least one combustion chamber, the burners of which comprise a pilot burner and a main burner and by which different fuel types are introduced into the combustion chamber for combustion, the method comprising: delivering of fuel of a first fuel type to the pilot burners; and delivering of fuel of the first fuel type to the main burners; wherein the steps are carried out during the acceleration of a rotor of the gas turbine from standstill up to a nominal rotational speed, and wherein fuel of a second fuel type is delivered to at least one burner before the nominal rotational speed is reached. ### Claim 2 (depends on 1) The method as claimed in claim 1, wherein the fuel of the second fuel type is delivered to the pilot burners. ### Claim 3 (depends on 1) The method as claimed in claim 1, wherein the delivery of fuel of the second fuel type takes place only after the delivery of fuel of the first fuel type to the main burners. ### Claim 4 (depends on 1) The method as claimed in claim 1, wherein, with the delivery of fuel of the second fuel type, the fuel quantity of the first fuel type delivered to the pilot burner is initially reduced. ### Claim 5 (depends on 1) The method as claimed in claim 1, wherein one of the two fuel types is gaseous and the other of the two fuel types is liquid. ### Claim 6 (depends on 5) The method as claimed in claim 5, wherein the first fuel type is gaseous and the second fuel type is liquid.
