Assignee:

General Electric Company - Schenectady NY

International Classification:

F01D009/02

US Classification:

415191, 4151995, 4152093, 2988922

Abstract:

A wedge-like nozzle radial loading pin, preferably formed from steel, that contacts the bottom of a reaction nozzle along a graduated, that is inclined or stepped, surface. This contact will secure the reaction nozzle radially inward against the retaining surface of the carrier dovetail with sufficient force to maintain the designed airfoil pre-twist.

International Classification:

F01D 9/00

US Classification:

4151995, 416215, 416212 R

Abstract:

The steampath for a steam turbine includes stacked stator rings each mounting inwardly directed nozzles and stacked rotor wheels each mounting outwardly directed buckets mounting blades. By alternately stacking the stator rings and rotor wheels, the nozzles and buckets of the various stages are interdigitated to form a steampath. Each bucket includes a blade and a root received in a generally complementary shaped groove on a wheel.

Assignee:

General Electric Company - Schenectady NY

International Classification:

F01D 25/24

US Classification:

4152141, 415220, 411351, 411999

Abstract:

A method of assembling a turbine casing is provided. The method includes inserting a bolt assembly through a first opening defined generally vertically through a first flange extending from a first casing member, such that a portion of the bolt assembly extends a distance upward from an upper surface of the first casing flange and such that the bolt assembly is retained within the first opening. The method further includes positioning a second casing member including a second flange including a second opening defined therein against the first casing member such that a portion of the bolt assembly extends through the opening defined in the second casing flange.

International Classification:

F03B 11/02

US Classification:

4152141, 4152151

Abstract:

A steam turbine apparatus is disclosed. In one embodiment, the steam turbine apparatus comprises: an exhaust shell portion including: a first section having a semi-circular cross-section; an exhaust section contiguous with the first section, the exhaust section including an intermediate-pressure exhaust outlet; and a second section having an oblate spherical cross-section including a substantially flattened portion, the second section configured to fluidly connect with the first section, wherein the first section and the second section form a continuous steam flow path.

International Classification:

B63H001/16

US Classification:

41619300A

Abstract:

A method and system of constructing equivalent integral covered blading for a turbine having multiple blades supported by a stator include multiple blade foils; multiple respective cover portions defining a first surface configured to span tips of multiple adjacent blades between tip locations of adjacent blades thereby to form the cover portion portions for adjacent blades and wherein the cover portions associated with each respective adjacent blades include facing sides for adjacent cover portions of adjacent blades; and an overcover coupled to a second surface opposite the first surface of the respective cover portions, the overcover configured to at least one of stiffen deterministic constraints of the tips and seal against leakage through the facing sides for adjacent cover portions.

Assignee:

General Electric Company - Schenectady NY

International Classification:

F01D 25/14
F16L 53/00

US Classification:

285 41

Abstract:

An intermediate, temperature reducing flange is inserted between an external steam (process) connection flange and first pressure vessel, or outer shell of a turbine or a second pressure vessel, or inner shell of the turbine. The temperature reducing flange has an integral portion that is exposed to an internal turbine area that is at a lower temperature than the steam in the steam inlet port of the turbine. This portion provides for a cooling effect, thus isolating the outer shell of the turbine from the high temperature of the steam pipe. Isolating the highest temperature connections from the remainder of the outer shell allows use of lower cost alloys for the outer shell.
