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.
