摘要: A combustor 500 is composed of a plurality of premixed combustion burners 100 each comprising a fuel nozzle 110 provided in a burner tube 120, the fuel nozzle 110 having a plurality of swirl vanes 130 on an outer peripheral surface thereof. Injection holes 133a, 133b are formed in each swirl vane 130. Staging control is exercised such that when a gas turbine is in a full load state, a fuel is injected through the injection holes 133a, 133b of all the swirl vanes 130, and when the gas turbine is under a partial load, the fuel is injected only through the injection holes 133a, 133b of a specific number of the swirl vanes 130 adjacent in a circumferential direction, and fuel injection through the injection holes 133a, 133b of the remaining swirl vanes 130 is stopped. By performing such staging control over fuel injection or its stoppage for the swirl vanes 130, a fuel-air ratio can be increased locally, generation of CO and UHC can be suppressed, and high efficiency combustion can be achieved, even under the partial load.

摘要: In a combustor, divisional fluid passages of a first group, and divisional fluid passages of a second group are present on an inner peripheral side, and divisional fluid passages are also present on an outer peripheral side, and swirl air flows are gushed from the divisional fluid passages. When the total amount of fuel supplied to the combustor is small as in a speed increasing state or in a low load state, fuel is injected only into the divisional fluid passages of the first group. Since a fuel injection region is limited to a position on the inner peripheral side, particularly, a specific position, the concentration of a fuel gas comprising a mixture of fuel and air is lean, but is higher than a flammability limit concentration, even when the total amount of fuel is small.
