Assignee:

General Electric Company - Schenectady NY

International Classification:

F01K 25/08
F01K 25/00
F28D 15/00

US Classification:

60651, 60671, 16510426

Abstract:

A first portion of each of a plurality of Qu-type heat pipes is disposed in a hot gas path, and a second portion of each of the plurality of Qu-type heat pipes disposed away from the hot gas path. Also, the first portion of each of the plurality of Qu-type heat pipes extracts heat from the hot gas path and wherein the second portion of each of the plurality of Qu-type heat pipes creates a vapor that exits each second portion of the plurality of Qu-type heat pipes and away from the hot gas path.

International Classification:

F02C 9/20
F01K 23/10

Abstract:

A method to adjust the back pressure applied to an exhaust of a gas turbine, the method including: exhausting hot combustion gas from the gas turbine; passing the hot combustion gas through a heat recovery steam generator; actuating an exhaust gas damper in the stream of the hot combustion gases, wherein actuation moves the exhaust gas damper to a restricted position, and while in the restricted position, the exhaust damper creates a backpressure applied to the exhaust gas, wherein the backpressure reduces an exhaust gas velocity at an exhaust of the gas turbine.
