    • 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.
    • 一种用于减少NOx生产的燃气轮机燃烧器。 燃烧器包括头部燃烧室和直径大于头部燃烧室的后部燃烧室。 头部燃烧室设置有轴向延伸的中空截头圆锥​​形管状构件以在其中形成环形燃烧空间,用于将空气轴向地喷射到环形燃烧室中的气孔,形成在用于喷射空气的周壁上的气孔和多个燃料喷嘴 投射到环形燃烧空间中,用于将燃料喷射到由空气射流和喷射空气流形成的涡流中,从而使火焰稳定并且可以实现贫燃。 后燃烧室在上游侧具有燃料和空气供给装置,其包括由旋转叶片形成的空气入口和设置在空气入口中的燃料喷嘴,使得燃料和空气充分混合。 燃料和空气混合物在旋转时基本上轴向地喷射,从而避免形成热点并且非常限制NOx的形成。
