Method of operating a gas turbine with different fuels, and gas turbine

The method for the running of a gas turbine (11) which at full load is run on a first fuel, entails running the turbine on a second fuel at part load to improve the emissions characteristic. The second fuel in relation to the first has a larger portion of higher level hydrocarbons (C2+) with two and...

Zusammenfassung:	The method for the running of a gas turbine (11) which at full load is run on a first fuel, entails running the turbine on a second fuel at part load to improve the emissions characteristic. The second fuel in relation to the first has a larger portion of higher level hydrocarbons (C2+) with two and more carbon atoms per molecule like, for example, ethane (C 2H 6) and propane (C 3H 8). Gaseous fuels are used as the first and second fuel supplied from two separate gas sources. An independent claim is included for a gas turbine installation for the executing of the proposed running method in which means are provided for the controlled change of the composition of the fuel flowing through the main fuel line (17).
