摘要： An array of blades for use in a turbomachine is provided comprising a plurality of blades mounted to a rotor disk. A plurality of first blades form a first set of blades and a plurality of second blades form a second set of blades. A blade-to-blade flow field defined between successive ones of the first set of blades is interrupted by the second set of blades to form an asymmetric blade-to-blade flow field around the array of blades. The trailing edges of the second set of blades are positioned forwardly from a line connecting the trailing edges of the first set of blades such that shock forces in the flow field around the array of blades will generally impinge on a stable region of the first set of blades.

摘要： A steam turbine having improved stationary parts in which a moisture removal slot is formed in a blade ring cylinder immediately upstream of the last row of rotating blades. The slot has a reduced width inlet throat portion and an enlarged manifold portion. The manifold portion of the slot distributes the moisture collected to a plurality of radially oriented discharge holes formed in the blade ring. The inlet throat serves to insolate the manifold from the swirling steam flowing through the turbine, thereby preventing entrainment of the moisture droplets into the steam flow. The blade ring encircles the tips of the last row of rotating blades and the outer flow guide is integrally formed on the blade ring. The steam turbine also has a new inner flow guide that matches a new last row of rotating blades. The new inner flow guide is attached to the existing inner flow guide by welds.

摘要： A pressure sensing probe 10 includes an elliposoidally shaped symmetric probe body 12 with fluid orifices 14 and 16 facing into and away from the flow. The orifices 14 and 16 facing in opposite directions allows direction of flow to be detected along with pressure magnitude. The symmetric body shape allows the probe 10 to operate satisfactorily with some misalignment with respect to the flow direction 32 but perpendicularity between orifices 14 and 16 and the flow direction 32 is preferred. The body 12 is ellipsoidally shaped to maximize the difference in pressure between the two orifices 14 and 16 and is held away from pipe wall turbulence by a symmetric stem 18. The ellipsoidal shape of the body 12 and stem 18 are also designed to minimize turbulence in the fluid created by the probe 10. The length to diameter ratio of the ellipsoidal shape of the probe body 12 changes depending upon fluid density and flow speed and the desires to maximize the pressure signal while minimizing flow disturbance. As the length to diameter ratio is minimized the differential pressure sensed is maximized and as the ratio is maximized flow disturbance is minimized. The orifices 14 and 16 communicate with a conventional differential pressure sensing device 24 outside the pipe through tubes 20 and 22 passing through the body 12 and stem 18. An alternate probe 40 with a greater range of flow direction insensitivity has funnels 50 and 52 which direct flow past orifices 44 and 46 in an internal flow channel 48. A further alternate probe has a solid body 90 suspended from the pressure sensing tubes 98 and 100 with perforations 102 in the tubes 98 and 100 at the juncture of the tubes 98 and 100 and the body 90.

摘要： A method and apparatus for reducing steam swirl in a steam turbine. A plurality of seal segments (14) are circumferentially juxtaposed to form a seal ring (12) encircling the turbine shaft (10), each seal segment (14) supporting a plurality of circumferentially disposed annular seal fins (20) to limit axial steam flow along the shaft (10). A plurality of flow dams (40) are disposed within grooves (42) defined in the plurality of seal fins (20) and seal segments (14) for limiting circumferential steam flow and thereby reducing rotor instability.

摘要： A support configuration between a turbine and associated condenser for compensating unbalanced pressure forces on the turbine with unbalanced pressure forces exerted on the condenser. A portion of the condenser floor is elevated above the remaining part of the condenser floor, is flexibly connected therewith, and constitutes a vacuum balance plate which is structurally connected to the turbine. Due to its flexible connection with the condenser, the vacuum balance plate is permitted limited displacement relative to the remaining portion of the condenser floor and can thus transmit unbalanced pressure forces exerted thereon through the structural members to the turbine so as to minimize the condenser vacuum load on the turbine's foundation. The vacuum balance plate's elevation is greater than the condenser's adjacent hot well floor and is preferably greater than the condenser's maximum condensate height. The balance plate is preferably convex to promote condensate drainage therefrom into the condenser's adjacent hot well. The balance of the condenser is flexibly connected to the turbine so as to permit relative movement therebetween. The optimum area for the vacuum balance plate is equal to the area of the turbine's exhaust port through which motive fluid is expelled into the condenser. By transmitting unbalanced pressure forces exerted on the condenser's vacuum balance plate to the turbine, the oppositely directed unbalanced pressure forces exerted on the turbine are substantially compensated resulting in minimized condenser vacuum load on the turbine's foundation.
摘要翻译：涡轮机和相关联的冷凝器之间的支撑构造，用于补偿作用在冷凝器上的不平衡压力的涡轮机上的不平衡压力。冷凝器地板的一部分在冷凝器地板的剩余部分上方升高，与其柔性连接，并且构成在结构上连接到涡轮机的真空平衡板。由于其与冷凝器的灵活连接，真空平衡板允许相对于冷凝器地板的剩余部分的有限位移，并且因此可以将施加在其上的不平衡压力通过结构构件传递到涡轮机，以使冷凝器真空负载最小化在涡轮机的基础上。真空平衡板的高度大于冷凝器的相邻热井地板，并且优选地大于冷凝器的最大冷凝物高度。平衡板优选是凸起的，以促进从其中排出冷凝物进入冷凝器的相邻热井。冷凝器的平衡被灵活地连接到涡轮机，以允许它们之间的相对运动。真空平衡板的最佳面积等于涡轮机排气口的面积，运动流体通过该面积排出到冷凝器中。通过将施加在冷凝器的真空平衡板上的不平衡的压力传递到涡轮机，施加在涡轮机上的相反导向的不平衡压力基本上被补偿，从而最小化涡轮机基座上的冷凝器真空负载。
