Abstract (en)
It is an object of the present invention to maintain flame stability in a combustor using coaxial jets even if NOx is further reduced. A combustor (100) includes a chamber (1) mixing and burning fuel and air; an air hole plate (50) disposed on a wall surface of the chamber (1), the air hole plate (50) including a plurality of rows disposed concentrically of a plurality of air holes (51) jetting coaxial jets of fuel and air into the chamber (1); and a first fuel nozzle (42) and a second fuel nozzle (43) disposed near a fuel hole jetting fuel into an air hole row on an inner peripheral side, the first fuel nozzle (42) being structured to suppress turbulence of a surrounding air flow and the second fuel nozzle (43) being structured to promote turbulence of a surrounding air flow. In accordance with the aspect of the present invention, good flame stability can be maintained even by further reducing NOx in a combustor using coaxial jets.
