Beschreibung
Zusammenfassung:	PURPOSE: To realize low NOX by a method wherein an operation is carried out with a dispersion type pilot burner from an activation of a gas turbine to a condition of about rated number of rotation in no-loaded state, the operation is adapted to an increased load during the operation by the dispersion pilot burner and a second premixing burner, and also a first premixing burner is added in a high load region. CONSTITUTION: Under a condition ranging from an energization of a gas turbine to about a rated number of rotation in non-load condition, fuel is passed to a dispersion pilot burner fuel system 203 and an operation is carried out with the dispersion pilot burner 8. Then, under a predetermined load, a fuel flow rate in a second premixing burner fuel system 202 is increased while a fuel flow rate of the dispersion pilot burner fuel system 203 is being decreased and for a subsequent increased load, flow rates in both fuel systems 202, 203 are increased and then the operation is performed with the dispersion pilot burner 8 and the second premixing burner 12. In addition, in a high load region, fuel is also supplied to the first premixing burner fuel system 201 and also the first premixing burner 9 is added to the operation.
