摘要： A turbine bucket is provided that can make centrifugal stress acting on a blade or dovetail not greater than a limit value of a material and that is provided with a shape of a blade root that can ensure a steam passage even if the blade is increased in length in order to increase an exhaust area.The turbine bucket is for a steam turbine low-pressure final stage and has an exhaust area exceeding 9.6 m2 (13.8 m2) in steam-turbine final-stage buckets for a rated speed 3600 rpm (3000 rpm) machine. The turbine bucket is made of martensite steel. A blade portion of the turbine bucket has a suction surface 7 and a pressure surface 8 which are each formed, at a turbine blade root, of three areas consisting of a steam inlet side area 12 with curvature, a steam outlet side area 13 with curvature and an approximately straightly formed area put between the two areas. An airfoil of the turbine bucket root is formed such that the relationship between a blade pitch t and a turbine-axial width BW of the blade portion is BW/t≧5.

摘要： In a turbine rotor in which a rotor material has lower tensile strength than a blade material and the difference in tensile strength between both the materials is large, a strength margin on the blade side is properly distributed to a strength margin on the rotor side with the aim of reducing shear stress in a rotor hook, increasing stiffness of the rotor hook, and reducing peak stress in a rotor neck, to thereby provide a steam turbine rotor and an inverted fir-tree turbine blade in which stress balance is made more appropriate depending on a material strength ratio of the blade material to the rotor material. In the turbine rotor, a rotor radial-direction hook length (Hri) of an i-th rotor hook counting from the outermost circumference of the rotor and a blade radial-direction hook length (Hbi) of an i-th blade hook counting from the outermost circumference of the blade are set to satisfy the relationship of (Hri>Hbi). In the turbine blade, a rotor circumference-direction neck width (Wri) of an i-th rotor neck counting from the outermost circumference of the rotor and a blade circumference-direction neck width (Wbi) of an i-th blade neck counting from the innermost circumference of the blade are set to satisfy the relationship of (Wri>Wbi).

摘要： An exhaust system for a steam turbine provided with an improved annular flow guide in a high or intermediate turbine. The improved flow guide reduces flow turbulence in an exhaust hood and reduces pressure loss to thereby improve turbine plant efficiency.The shape (vertically symmetric) of a flow guide 5A according to a conventional technology was modified into the shape (vertically asymmetric) of a flow guide 5 such that the length of a downstream flow guide portion 5d is greater than that of a upstream flow guide portion 5u. Numerical analyses were performed to find the optimum flow guide occupation ratio of the conventional technology and the corresponding total pressure loss coefficient. The obtained values were used as reference values. Further, the flow guide occupation ratio of the upstream flow guide portion 5u was set at 0.4 and the flow guide occupation ratio of the downstream flow guide portion 5d was set at 0.7; at values where the total pressure loss coefficient becomes lower than the reference value. The rectification effect of the flow guide can thus be enhanced.
摘要翻译：一种用于蒸汽轮机的排气系统，其在高级或中级涡轮机中设置有改进的环形流动引导件。改进的流动引导件减少排气罩中的流动湍流并减少压力损失，从而提高涡轮机厂的效率。根据传统技术的流动引导件5A的形状（垂直对称）被修改为导流器5的形状（垂直不对称），使得下游流动引导部分5d的长度大于上游流动引导件部分5u。进行数值分析，找出常规技术的最佳流量指数占有率和相应的总压力损失系数。将获得的值用作参考值。另外，将上游侧流动引导部5u的流动导向占有率设定为0.4，将下游侧流动引导部5d的流动导向占有率设定为0.7，其中总压力损失系数变得低于参考值。因此可以提高导流管的整流效果。

摘要： A sealing structure in which free-cutting spacers on a sealing base plate and sealing fins on a rotor are opposed to each other is provided. The sealing base plate is disposed so as to be movable in an axial direction of the rotor. When a steam turbine increases in load, a pressure head moves in an axial steam-pressure loading direction of the rotor and the sealing base plate connected to the pressure head moves in the axial steam-pressure loading direction. Since the free-cutting spacers at positions opposed to those of the sealing fins existing after the movement of the sealing base plate are maintained in a non-contact state, clearances between the sealing fins and the free-cutting spacers are dimensionally minimized.
