Abstract: The present application provides a pre-separator for use with a flow of steam entering a moisture separator reheater. The pre-separator may include a neck, an internal baffle, a wall, a first pathway defined between the neck and the internal baffle, and a second pathway defined between the internal baffle and the wall. The first pathway and the second pathway create a Coanda effect for the flow of steam entering the moisture separator reheater.

Abstract: An enclosure system includes a stator enclosure defining an enclosure opening, and an adapter having a first entry port, and defines a center cavity having a first volume. Enclosure system includes a conduit enclosure coupled to one or more of stator enclosure and adapter. Conduit enclosure includes a base member having at least one side wall, a rear wall coupled to side wall and defining a second entry port, an interior cavity, and a terminal connection block coupled to base member and having at least one terminal. Enclosure system includes at least one electrical lead extending from the stator enclosure through first enclosure opening, through first entry port, through center cavity, through second entry port, and into the interior cavity. Electrical lead occupies a portion of first volume and leaves a remaining volume. Enclosure system includes sealing compound coupled with adapter such that substantially all of remaining volume is occupied.

Abstract: An enclosure system for isolating a conduit enclosure for an explosion proof motor is provided. The enclosure system includes a stator enclosure defining a first enclosure opening. The enclosure system also includes a conduit enclosure coupled to the stator enclosure. The conduit enclosure comprises at least one side wall, a rear wall coupled to the side wall, and an interior cavity. The rear wall defines a first entry port having a first volume. The enclosure system further includes at least one electrical lead. The at least one electrical lead extends through the first enclosure opening, through the first entry port, and into the interior cavity. The at least one electrical lead occupies a portion of the first volume and leaves a remaining volume. The enclosure system also includes sealing compound. The sealing compound is coupled with the first entry port such that substantially all of the remaining volume is occupied.

Abstract: A shaft lubrication apparatus is provided and includes a rotatable shaft, a lubrication sump and a lubrication ring. The lubrication ring is rotatable with the rotatable shaft with respect to the lubrication sump whereby lubrication is transported from the lubrication sump to the rotatable shaft.

Abstract: A heat exchanger having at least one corrugated sheet and a method of creating the heat exchanger are provided. The method includes providing at least one corrugated sheet. The at least one corrugated sheet has at least one joining portion and at least one groove portion. The method includes providing a joining surface for the at least one corrugated sheet. The method also includes joining the at least one corrugated sheet at the least one joining portion with the joining surface. The joining surface cooperates with the at least one groove portion of the at least one corrugated sheet to create at least one passageway. The at least one passageway is configured for the passage of fluid.

Abstract: Disclosed is a non-contacting seal arrangement, an electromechanical system having a non-contacting seal arrangement, and a process of fabricating a non-contacting seal arrangement. The non-contacting seal arrangement includes a shape-memory alloy portion, a non-contacting seal, and an ingress gap. The ingress gap is between the non-contacting seal and the shape-memory alloy portion, between a surface of an electromechanical system and the non-contacting seal, or between the surface of the electromechanical system and the shape-memory alloy. An increase in temperature expands the non-contacting seal and the shape-memory alloy portion substantially maintains the ingress gap. The electromechanical system includes a rotating component and a surface extending around at least a portion of the rotating component and forming the ingress gap. The process includes securing the shape-memory alloy portion, securing the non-contacting seal, and forming the ingress gap.

Abstract: A fully bladed closure design for a turbine wheel with tangential entry. A set of the final three buckets including a bladed closure bucket are disposed about a wheel margin with two buckets adjacent to the bladed closure bucket secured to the wheel margin by the dovetails. The closure bucket is secured to adjacent buckets by a combination of one or more retaining keys and to the margin by one or more retaining pins. The bladed closure bucket and the adjoining faces of the adjacent buckets have flat skirts providing suppport from the retaining keys across the full axial width of the bladed closure bucket and the adjacent buckets.
