摘要:
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.
摘要:
An expansion joint for use between a turbine duct and an exhaust duct. The expansion joint may include a flange attached to the turbine duct and a number of plates attached to the exhaust duct that extend towards the flange. The plates and the flange may include a gap therebetween, the gap being narrower when the turbine duct is hot than when the turbine duct is cold.

摘要:
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.
摘要:
An expansion joint seal between a gas turbine exhaust duct and an axially adjacent exhaust ductwork comprising plural layers of axially adjacent layers of flexible seal plates, each layer comprising a plurality of arcuate segments which together form a 360.degree. annulus; and further wherein the plural layers of flexible seal plates are secured at one end to the gas turbine exhaust duct, with opposite ends of the seal plates slidably engaged with at least one surface of the exhaust ductwork.
