Abstract
The invention relates to a method for compensating variations in fuel composition in a gas turbine system consisting of at least two parallel-operated burner stages, wherein the fuel supply to at least two of the burner stages is adjusted in response to variations in fuel composition, wherein the fuel split between the burner stages, i.e. the relative increase in speed of the fuel supplied to the burner stages, is adjusted to a target value or maintained at a target value during adjustment of the fuel supply. The target value can, for example be a constant or a function of one or several variables. More particularly, the gas turbine system can comprise a pilot burner stage and a main burner stage. When the fuel supply is adjusted, the fuel split between the pilot burner stage and the main burner stage is adjusted to a target value or maintained at a target value.
