  • Patent number: 8403628
    Abstract: 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.

  • Patent number: 8221053
    Abstract: 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.

  • Publication number: 20100162705
    Abstract: An axial flow steam turbine flow path that includes a rotor and a casing defining the axial steam flow path; and a toroidal diffuser for diffusing the exhaust steam and turning the exhaust steam from a generally axial flow direction to a generally transverse or vertical and tangential direction; wherein the toroidal diffuser comprises a diffuser that, at least in part, incorporates the shape of a toroid or a section of a toroid; and wherein a toroid comprises the shape generated by revolving a circular or oval shape in three dimensional space about an axis coplanar with the circular or oval shape, which does not touch the circular or oval shape.

  • Patent number: 6821083
    Abstract: A casing (12) for a steam turbine section has a housing (14) installed therein for a bearing supporting a rotor for buckets. A housing support structure (10) includes a pair of horizontally extending struts (T1-T2) extending from a side (18) of the casing to the housing and a second pair of struts (T3, not shown) extending from the opposite side of the casing to the housing. The struts are in fluid communication with the interior of the housing and the atmosphere and both support the housing within the casing and vent the interior of the housing. Vertical struts (T4-T6) also extend between the casing and the housing. A foundation plate (20) is installed beneath the casing, and a pair of gibs (28) are installed on opposite sides of the casing along the longitudinal centerline thereof to strengthen the casing and prevent tilting of components within the casing when a vacuum within the casing is present.

  • Publication number: 20040052638
    Abstract: A cover is provided to conceal the forward-facing step defined by the protrusion of the first stage diaphragm into the LP inlet. The cover presents a smoothly contoured surface to the flowing fluid in both radial and circumferential directions and thus reduces energy loss of the working fluid, thereby to increase performance of the LP turbine.

  • Patent number: 5560818
    Abstract: A conventional gas-sparged hydrocyclone, including a plug that cooperates with an interior surface of the hydrocyclone to adjust the size of an orifice defined adjacent the suspension outlet, is mechanically adjusted. The plug position is adjusted by a mechanical device from a position exteriorly of the hollow body while the hydrocyclone is running with suspension fed to its inlet, to effect direct linear movement of the plug with respect to the body interior surface. The mechanical elements include first and second pins and links within the hydrocyclone, a shaft having a drive portion extending exteriorly of the hydrocyclone, and a manually actuated link assembly or stepper motor for rotating the shaft. The manual actuator may be associated with an indexing arrangement to positively hold the plug at the position to which it has been adjusted.
