|1. (WO2016056180) GAS TURBINE ENGINE COMBUSTOR AND OPERATING METHOD FOR SAME|
|Applicants:||KAWASAKI JUKOGYO KABUSHIKI KAISHA
|Title:||GAS TURBINE ENGINE COMBUSTOR AND OPERATING METHOD FOR SAME|
A fuel injecting device (36) for a combustor (12) has a pilot burner (40) and a main burner (4). The main burner (4) has at least one first fuel injection port (41a) to supply a first fuel to an upstream section of a combustion chamber (35) and at least one second fuel injection port (42a) to supply a second fuel to the upstream section of the combustion chamber (35). During startup, the operation of the combustor (12) is controlled so that the main burner (4) is ignited by the flame of the pilot burner (40) and the first fuel is burned as the primary fuel, and when a gas turbine engine 1 satisfies prescribed rated operation conditions, the fuel is switched so that the second fuel that has a faster maximum burning rate than the first fuel is burned as the primary fuel by the main burner (4).
