Zusammenfassung:	PURPOSE:To enable the maintaining of a low NOx burning at a high efficiency by allowing stable combustion with a low NOx in a full load range while premixed combustion with a plurality of main burners is kept with a better balance even when a backfire occurs. CONSTITUTION:In a combustion apparatus of a gas turbine in which a plurality of main burners 8 are arranged in the perimeter of a pilot burner 7 provided at the center of a combustion chamber, a fuel supply controller is provided to accomplish a pre mixed combustion with a pilot burner 7 by supplying a quantity of a fuel equivalent to that to be supplied to the main burners 8 to the pilot burner 7 when a backfire occurs in one of the burners 8.
