Abstract
A combustor of the prior art that defines the outlet position and direction of an air hole and suppresses adhesion of flame to an air hole outlet can reduce a discharge amount of NOx by increasing a distance over which fuel and air are mixed with each other. However, such a combustor is not sufficiently discussed for measures to suppress the occurrence of combustion oscillation resulting from the variation of a flame surface. A combustoraccording to the present invention includes a combustion chamberto which fuel and air are supplied; air holesadapted to supply air to the combustion chamber; fuel nozzlesadapted to supply gaseous fuel to the air holes; and orificesadapted to allow the gaseous fuel supplied to the air holesto cause a pressure drop.
