20120282083 | TURBINE CASING HAVING LEDGE RING PARTITION APERTURE - A turbine casing segment is disclosed. In one embodiment, a turbine casing segment is disclosed including: a plurality of stage segments; a plurality of ledge ring partitions separating the plurality of stage segments, wherein at least one of the plurality of ledge ring partitions has an axially extending aperture therethrough; and a substantially rounded extraction aperture located flush with an inner surface of one of the plurality of stage segments. | 11-08-2012 |
20120282089 | SUPPORT ARRANGEMENT FOR A STEAM TURBINE LP INNER CASING - A support arrangement is provided for an inner casing of a turbine having an inner casing with upper and lower sections secured together along a first interface lying substantially in a horizontal plane containing a longitudinal centerline of a turbine rotor. An outer shell substantially encloses the inner casing, and in the inner casing is supported directly on an external foundation at a mounting location below the longitudinal centerline. | 11-08-2012 |
20140119886 | TURBINE COWLING SYSTEM - A steam turbine cowling system is disclosed. The steam turbine cowling system including: a lower portion configured to be disposed proximate an inner casing of a steam turbine; and an upper portion connected to at least one of the lower portion and the inner casing, the upper portion shaped to be disposed proximate the inner casing of the steam turbine, the upper portion substantially defining a flowpath about the inner casing. | 05-01-2014 |
20140119910 | TURBINE EXHAUST HOOD AND RELATED METHOD - A turbine exhaust hood and related method of installation is disclosed. In one embodiment, the turbine exhaust hood includes: a housing having an end wall, the end wall including a first portion of a releasable coupling, and a first radially inner steam guide structure disposed within the housing, the first radially inner steam guide structure including a second portion of the releasable coupling, integral with a first end of the first radially inner steam guide structure. The first portion and the second portion of the releasable coupling releasably couple the first radially inner steam guide structure to the end wall. | 05-01-2014 |
20140271139 | TURBINE CASING INLET ASSEMBLY CONSTRUCTION - A steam turbine inlet assembly and method of constructing the same are disclosed. In an embodiment, an annular ring is provided, along with a body affixed to a distal face of the annular ring and extending distally therefrom. The body portion has a curved entrance geometry at the proximal end adjacent the annular ring, and transitions to a substantially polygonal exit geometry at a distal end. | 09-18-2014 |
20140271155 | MODULAR TURBOMACHINE INLET ASSEMBLY AND RELATED INLET TRANSITION SECTION - An inlet transition section and an inlet bowl entry can be designed to reduce a number of turbomachine casing designs. Using relationships between flow properties, distances between elements, crossover/supply pipe diameter, ideal cross sectional area, aspect ratio, and inlet bowl entry size, a transition from circular cross section to substantially polygonal cross section can be made while enabling adoption of a single size of substantially polygonal inlet bowl entry for a plurality of turbine sizes and/or crossover/supply pipe sizes with minimal losses. | 09-18-2014 |
