Abstract: An improved moisture separator suitable for a nuclear steam turbine-generator power plant is disclosed. The separator is of the type having wiggle plate or inertial-type moisture separator elements aranged in axially disposed banks within a generally horizontal, cylindrical vessel, sealed at both ends. Wet steam inlets are provided below the horizontal axis of the vessel and dry steam outlets are placed above the axis. Impingement baffles are provided for each steam inlet; these baffles are disposed between the wet steam inlets and the moisture separator elements. An axially extending trough is provided for directing condensate from the moisture separator elements to a hotwell. The trough is substantially enclosed to provide a sheltered collection area for the condensate and prevent the reentrainment of condensate in the steam flowing through the separator.

Abstract: An axial flow turbine incorporating an exhaust hood for receiving exhaust steam from the turbine and directing this exhaust steam through a discharge opening in the hood in a direction essentially normal to the axis of the turbine is disclosed. The exhaust hood includes a first set of guide vanes arranged in an exhaust duct connected to the turbine adjacent the last stage buckets thereof. These vanes are curved to provide a relatively smooth transition of steam flow from an axial direction to a generally radial direction. A guide ring circumferentially surrounds the first set of guide vanes and a plurality of secondary vanes are circumferentially spaced around this guide ring. Steam which is discharged radially from the first set of vanes to the secondary vanes is directed by the secondary vanes to the discharge opening of the exhaust hood.

Abstract: An improved reheater for a moisture separator reheater is provided with a header having first and second baffles disposed therein, dividing the interior of the header into inlet, recirculation and outlet flow chambers. The improved reheater also includes two bundles of U-shaped tubes communicating with the header via a tube sheet. Each tube of the first bundle communicates with the header at the inlet and recirculation chambers. Each tube of the second bundle communicates with the header at the recirculation and outlet flow chambers. This arrangement effects a four-pass recirculation of reheating fluid through the improved reheater. Drains are provided at both the recirculation and outlet flow chambers to prevent condensate flooding and any resulting thermal cycling and rupture of the tubes.
