Filed:

Jan 27, 2004

Appl. No.:

10/766140

Inventors:

Yu Wang - Mason OH, US
Robert Adolph Ackermann - Schenectady NY, US

Assignee:

General Electric Company - Niskayuna NY

International Classification:

F25B 19/00
F25B 9/00

US Classification:

62 6, 62 511, 622592

Abstract:

A superconducting machine includes a superconductive device and a vacuum enclosure containing and thermally insulating the superconductive device. A cold-trap is configured to condense gases generated within the vacuum enclosure, and a coolant circulation system is adapted to force flow of a cryogen to and from the superconductive device and the cold-trap. A cryogenic cooling system is configured to cool the cryogen in the coolant circulation system upstream of the superconductive device. A vacuum retention method, for a high-temperature superconductive HTS device, includes applying vacuum to the HTS device to thermally insulate the HTS device, condensing gases generated around the HTS device using a cold-trap, flowing a cryogen to and from the HTS device, and flowing the cryogen to and from the cold-trap.

Assignee:

General Electric Company - Schenectady NY

International Classification:

F02C 7/08

US Classification:

60736, 60 39511, 60267

Abstract:

A method for heating a fluid in a turbine engine is provided. The method includes channeling an exhaust flow through an exhaust duct of the turbine engine and coupling a panel to the exhaust duct. The panel includes a first wall and an opposite second wall that is spaced a distance from the first wall such that at least one passageway is defined within the panel. The fluid is supplied to the at least one passageway through an inlet defined at a first end of the passageway, such that heat is transferred from the exhaust flow to the fluid flowing through the panel. The fluid is injected into the turbine engine.

Assignee:

General Electric Company - Schenectady NY

International Classification:

B23P 6/00

US Classification:

298891, 2988922, 2940208

Abstract:

A method facilitates extending the useful life of a turbine engine including a combustor and a turbine downstream from and in flow communication with the combustor. The method comprises identifying at least a portion of the combustor that is at least one of distressed, worn, deteriorated, satisfied pre-determined threshold data, and beyond serviceable limits, identifying at least one enhancement kit for installation within the combustor, and removing at least two portions of the combustor including at least two of a combustor dome assembly, a swirler/cowl assembly, and the combustor inner and outer liners. The method also comprises installing the enhancement kit within the turbine engine such that a useful life of the turbine engine is facilitated to be increased.
