摘要： A gas turbine combustor comprises an inner cylinder provided with louvers in an outer periphery thereof, defines a head combustion chamber and a main combustion chamber located downstream of and greater in diameter than the head combustion. An outer cylinder surrounds the inner cylinder and defines an air passage therebetween. A first burner communicates with the head combustion chamber and supplies air with gaseous fuel, and a second burner being disposed in the air passage near the head combustion chamber and supplying air and gaseous fuel into the main combustion chamber. The second burner is formed with a plurality of air inlets by a plurality of vanes which are disposed in an annular passage and which swirl the air, and with gaseous fuel jet ports near the inner peripheries of the air inlets. When the flow rate of the supplied fuel is small, the fuel flows along an inner-peripheral surface of the second burner, and when the flow rate is large, the fuel from the air inlets moves from the inner-peripheral surface toward the outer-peripheral surface of the second burner so as to be mixed well with the air supplied into the main combustion chamber. Thus, the production of NO.sub.x, CO, HC etc. can be decreased over the whole operating range of the turbine.

摘要： A gas turbine combustor for reducing a production of NOx. The combustor includes a head combustion chamber and a rear combustion chamber which is larger in diameter than the head combustion chamber. The head combustion chamber is provided with an axially extending hollow frustoconical tubular member to form an annular combustion space therein, air holes for axially jetting air into the annular combustion chamber, air holes formed on a peripheral wall for injecting air and a plurality of fuel nozzles projected into the annular combustion space for injecting fuel into vortex formed by the air jet and the injected air flow whereby the flame is stabilized and lean combustion can be effected. The rear combustion chamber has a fuel and air supply means on the upstream side which includes air inlets formed by whirling vanes and fuel nozzles disposed in the air inlets so that fuel and air are mixed well. The fuel and air mixture is jetted substantially axially while whirling it so that formation of hot spots is avoided and the NOx formation is extremely limited.
