摘要： An arrangement and method adapted for providing a stiffened lower exhaust hood for a steam turbine. Sidewalls of the lower exhaust hood may taper inward between a horizontal joint and an inlet to a condenser for the steam turbine, providing an enhanced flow path for the exhaust steam. Stiffening of the sidewalls may be provided by stiffening bends, stiffening curvature, and external stiffening beams on the wall plate of the sidewalls of the lower exhaust hood, permitting reduction or elimination of structural supports within the exhaust hood, which degrade exhaust steam flow.

摘要： A support arrangement for an exhaust hood. The inner casing in the inventive arrangement is supported directly by the curb foundation. As a result, the effect of pressure changes in the exhaust hood are eliminated and the effect of temperature changes of the exhaust hood are reduced relative to the positioning of the inner casing and the rotor within it. Shaft bearings may be outside the exhaust hood located in a standard directly on the foundation. Rotor end packing may also be attached to the standard. The exhaust hood can be a much simpler design with less structural supports and less fabrication time. Easier maintenance is facilitated because the shaft bearings are not tucked under the exhaust hood and the end packing can be removed without removal of a large section of the exhaust hood.
摘要翻译： 排气罩的支撑装置。 本发明装置的内壳直接由路缘基础支撑。 结果，消除了排气罩中的压力变化的影响，并且排气罩的温度变化的影响相对于内壳体和转子在其内的定位而降低。 轴承可能位于直接位于基础上的标准的排气罩外。 转子端部填料也可以附在标准上。 排气罩可以是更简单的设计，具有较少的结构支撑和较少的制造时间。 由于轴承没有被排放在排气罩下面，因此容易维护，并且可以在不排除排气罩的大部分的情况下去除端部衬垫。

摘要： Turbine stator vane segments have inner and outer walls with vanes extending therebetween. The inner and outer walls are compartmentalized and have impingement plates. Steam flowing into the outer wall passes through the impingement plate for impingement cooling of the outer wall surface. The spent impingement steam flows into cavities of the vane having inserts for impingement cooling the walls of the vane. The steam passes into the inner wall and through the impingement plate for impingement cooling of the inner wall surface and for return through return cavities having inserts for impingement cooling of the vane surfaces. The trailing edge is air-cooled.

摘要： In a method of investment casting a turbine nozzle which includes an outer band, an inner band and an airfoil section extending between the inner and outer bands, an improvement including shaping a temporary wax form, and external shell and internal core components used in casting such that during pouring of molten metal into a space created by removal of the wax form, shell material lies on opposite sides of an outer fillet connecting the outer band to the airfoil section. The resulting gas turbine nozzle includes first and second horizontally oriented ribs extending about interior peripheries of the airfoil section vertically adjacent the outer and inner band fillets.

摘要： Upper and lower diaphragms of a steam turbine have mating flanges forming a horizontal midline joint interface. Each flange has a groove which registers with a corresponding groove in the opposite flange. A composite woven tubular seal is provided in the mating grooves. The seal comprises an inner woven metal core surrounded by an annular silica fiber layer, in turn surrounded by a metal foil with an outer protective covering of a braided stainless steel. Upon joining the diaphragms to one another, the compliant seal generally conforms to a maximum to the shape of the grooves, maintaining a seal between the diaphragms along the horizontal midline joint.
