Abstract
A method of operating a combustion system () for a gas turbine (), the combustor system () comprises a main fuel supply (), a pilot fuel supply (), a combustion chamber (). The method comprises the steps supplying a first fuel flow through the main fuel supply () and the pilot fuel supply (), monitoring a composition of the first fuel, monitoring combustion instability, reducing the first fuel flow through the pilot fuel supply () to zero when the first fuel composition has a) a hydrogen content ≥5% by volume and/or b) a high-HC content ≥5% by volume and the combustion instability <a predetermined value.
