The invention is directed to a method of operating a burner. The method includes feeding an auxiliary gas into a liquid fuel upstream of an injection orifice during the ignition and during part load of the burner, and interrupting the feeding of the auxiliary gases within high load ranges of the burner.
Claims11
A method of operating a gas turbine burner comprising the steps of:
- directing a liquid fuel having a fuel pressure into an atomizing nozzle of the gas turbine burner;
- introducing an auxiliary gas having a pressure higher than the fuel pressure into the liquid fuel during an ignition and a part load condition of the gas turbine burner;
- interrupting the introduction of auxiliary gas into the liquid fuel during a high load range of the gas turbine burner;
- and
- ejecting the liquid fuel through an injection orifice of the gas turbine burner;
- wherein the step of introducing the auxiliary gas further includes continuing to feed the auxiliary gas when the supply of liquid fuel to the gas turbine burner is interrupted.
