International Classification:

F02C007/00

US Classification:

060/039500

Abstract:

A gas turbine exhaust diffuser includes a substantially cylindrical outer casing provided with a forward casing flange; a substantially cylindrical liner spaced radially inwardly of, and secured to, the outer casing; and ceramic fiber insulation supported radially between the outer casing and the liner. A plurality of liner closeout segments are secured to the liner and include radial flange portions extending toward the forward casing flange. A plurality of spacer rings are supported between the forward casing flange and the liner closeout segments such that one of the spacer rings and the liner closeout segments present a flat face for direct attachment to an aft flange component of a gas turbine exhaust frame. This arrangement provides a thermally compliant load bearing interface between an air cooled gas turbine flange and an internally insulated diffuser casing flange in the high velocity section of the exhaust diffuser.

Abstract:

An inlet bleed heater for flowing heated air to the inlet of a compressor is fabricated wholly at a factory site. The heater interconnects a manifold which receives extraction air from the compressor to down tubes in the inlet air duct to supply heated extraction air to the ambient inlet air via piping with bellows. The bellows accommodate thermal expansion and contraction of the manifold and the down tubes. The pipe and bellows lie within the height envelope of the bleed heater, facilitating transportation of the heater on its side within overall height and width limitations permitted for road travel.
