摘要： An object of this invention is to accelerate further mixing of a fuel and air independently of a flow rate of the fuel.A gas turbine combustor comprises: a fuel nozzle for blowing out a gas fuel; an air nozzle plate with an air nozzle for jetting out the fuel and air into a combustion chamber after the blowout of the fuel from the fuel nozzle; and an obstacle formed inside the air nozzle; wherein the obstacle causes a collision of the fuel jet blown out from the fuel nozzle, and hence causes turbulence in an airflow streaming into the air nozzle.According to the invention, mixing between the fuel and the air can be further accelerated independently of the flow rate of the fuel.

摘要： 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 combustor 2 according to the present invention includes a combustion chamber 5 to which fuel and air are supplied; air holes 32 adapted to supply air to the combustion chamber 5; fuel nozzles 25 adapted to supply gaseous fuel to the air holes 32; and orifices 24 adapted to allow the gaseous fuel supplied to the air holes 32 to cause a pressure drop.
