Abstract

A gas turbine employing as a main fuel a fuel having a variable heating value and as an auxiliary fuel a fuel having a stabilized heating value in which stabilized combustion free from blow-off and overheat is ensured. A combustor (5) comprises a first burner (105) for injecting fuel and air into a combustion chamber, and a second burner (108) for injecting fuel and air to the axial position in the combustor corresponding to the distal end of flame of the first burner such that the flame of the first burner is intercepted thus producing a circulation flow of fuel and air in the combustion chamber. An auxiliary fuel flow rate operation controller (33) and a main fuel flow rate operation controller (34) supply fuel having a stabilized heating value to the first burner at a predetermined flow rate calculated by the air flow rate of gas turbine, supply fuel having a variable heating value to the second burner, and then vary the flow rate of fuel supplied to the second burner based on a correction amount calculated by using the difference between a required gas turbine output and an actual gas turbine output.
