Abstract

Abstract A connection between a steam turbine (1) and a condenser (2), the turbine being supported by an admission end bearing (7) and by an exhaust end bearing (8), and exhausting axially into an end-located condenser via an exhaust sleeve (3) which is connected to the turbine stator at one end and which has its other end connected to the condenser via a sealed resilient connection (4), the turbine-condenser connection including the improvement whereby a tubular duct (44) passes freely through the condenser along the turbine axis, one end (45) of said duct being fixed to the fixed parts of the turbine exhaust end bearing, which parts are connected to said sleeve (3), and the other end (43) of said duct being connected to a flange (38) having the same diameter as the condenser end of the exhaust sleeve, with a sealed resilient connection (39) being provided between the periphery of said flange and the condenser.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 166 words
A connection between a steam turbine and an end-located condenser, said turbine including an axial shaft, a turbine stator about said shaft, said shaft being supported by an admission end bearing and by an exhaust end bearing, said exhaust end bearing including fixed parts, said turbine exhausting axially into said end-located condenser via an exhaust sleeve which is connected to said turbine stator at one end and which has its other end connected to the condenser via a sealed resilient connection, the turbine-condenser connection including the improvement comprising a tubular duct passing freely through the condenser coaxial with the turbine shaft, means fixing one end of said duct to the fixed parts of the turbine exhaust end bearing, said fixed parts being connected to said sleeve, and a flange connected to the other end of said duct said flange having the same diameter as the condenser end of the exhaust sleeve, and a sealed resilient connection provided between the periphery of said flange and the condenser.
Claim 2
Dependent Claim 166 words
A connection between a steam turbine and an end-located condenser, said turbine including an axial shaft, a turbine stator about said shaft, said shaft being supported by an admission end bearing and by an exhaust end bearing, said exhaust end bearing including fixed parts, said turbine exhausting axially into said end-located condenser via an exhaust sleeve which is connected to said turbine stator at one end and which has its other end connected to the condenser via a sealed resilient connection, the turbine-condenser connection including the improvement comprising a tubular duct passing freely through the condenser coaxial with the turbine shaft, means fixing one end of said duct to the fixed parts of the turbine exhaust end bearing, said fixed parts being connected to said sleeve, and a flange connected to the other end of said duct said flange having the same diameter as the condenser end of the exhaust sleeve, and a sealed resilient connection provided between the periphery of said flange and the condenser.
Claim 3
Dependent Claim 22 words
A turbine-condenser connection according to claim 1, wherein said turbine includes an axially fixed point situated level with its admission end bearing.
Claim 4
Dependent Claim 19 words
A turbine-condenser connection according to claim 1, wherein the condenser is connected to the ground via a transverse key.
