Abstract
A gas turbine plant having a combustion chamber (1) separate from the turbine (15) includes a conduit (16) with an inner tube (17), which conducts heated propellant gas from the combustion chamber (1) to the turbine (15); and an outer tube (18), which surrounds the inner tube (17) to form an annular gap (20) which conducts compressed air from a compressor (10) to the combustion chamber (1). (FIG. 1.)
Claims11
A gas turbine plant, comprising:
- a combustion chamber having an inlet and an outlet;
- a gas turbine having an inlet spaced from said combustion chamber;
- a compressor having an outlet for supplying compressed combustion air to said combustion chamber;
- an inner conduit arranged between said outlet of said combustion chamber and said inlet of said turbine and provided with an internal thermal insulation;
- a casing tube arranged inside and spaced from said inner conduit, thus forming an annular gap between said casing tube and said inner conduit;
- and
- an outer conduit, coaxially arranged around said inner conduit between said outlet of said compressor and said inlet of said combustion chamber for conveying air through a gap defined between said inner and outer conduits.

A gas turbine plant, comprising:
- a combustion chamber having an inlet and an outlet;
- a gas turbine having an inlet spaced from said combustion chamber;
- a compressor having an outlet for supplying compressed combustion air to said combustion chamber;
- an inner conduit fixed against axial movement relative to said combustion chamber, arranged between said outlet of said combustion chamber and said inlet of said turbine and provided with internal thermal insulation, said inner conduit comprising a plurality of axial sections, at least a portion of said sections comprising a sleeve adapted to receive the end of an adjacent section, said end comprising at least one seal ring for cooperation with said sleeve;
- an outer conduit fixed against axial movement relative to said combustion chamber and coaxially arranged around said inner conduit between said outlet of said compressor and said inlet of said combustion chamber for conveying air through a gap defined between said inner and outer conduits;
- and
- said inner and outer conduits having a bent section and coupling means between said bent section and said turbine for permitting displacement of said bent section relative to said turbine.
