Abstract

In a gas turbine having a plurality of hybrid burners, each of which has a pilot burner and a main burner, a different pilot fuel quantity is fed to the pilot burners as a function of the load on the gas turbine. This provides both stable operation of the gas turbine at low loads and effective suppression of combustion oscillations at high loads.
