    • 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。

    • A plurality of turbine buckets annularly arranged around a rotor are each provided with a ledge disposed at right angles to the outer surface of each bucket. Each ledge includes a leading end portion and a trailing end portion each formed therein with a vertical hole, leading and trailing end portions of the ledge of each turbine bucket extending in opposite directions on both sides of the bucket. There are provided cover pieces each interposed between ends of the adjacent two turbine buckets and formed on the upper surface with a plurality or cylindrical projections adapted to be loosely received in the vertical holes formed in the ledges of the adjacent two turbine buckets. Contact surfaces adapted to be brought into contact with the undersides of the ledges are formed on the upper surface of each cover piece and interposed between the cylindrical projections, and an upper end portion of at least one of the cylindrical projections is machined to provide an enlarged diameter projection portion so as to preclude dislodging of the projection from the hole whereby the cover piece can positively connect the adjacent two buckets together.
    • 围绕转子环形布置的多个涡轮机桶分别设置有与每个铲斗的外表面成直角设置的凸缘。 每个凸缘包括前端部分和后端部分,每个前端部分和后端部分均形成有垂直孔,每个涡轮机的凸缘的前端部分和后端部分在桶的两侧沿相反方向延伸。 设置有各自设置在相邻的两个涡轮叶片的端部之间的盖片,并且在上表面上形成有多个或圆柱形突起,其适于松动地容纳在形成在相邻的两个涡轮机叶片的壁架中的竖直孔中。 在每个盖件的上表面上形成适于与凸缘的下侧接触的接触表面,并且插入到圆柱形突起之间,并且至少一个圆柱形突起的上端部分被加工以提供扩大的 以防止突起从孔中移出,由此盖件可以将相邻的两个水桶正确地连接在一起。
