Definitions

  • the present invention relates to a connecting device between a steam turbine and a condenser.
  • the invention relates to turbines with axial exhaust with condenser at end. This is to ensure a suitable connection between the turbine and the condenser without the relative expansions which exist between the condenser and the turbine reacting abnormally on the turbine causing misalignments and deformations which impair the proper functioning of the turbine to steam.
  • An arrangement which consists in that the exhaust sleeve of the turbine is connected to the condenser by means of an expansion bellows making it possible to absorb the relative differences in vertical expansion between the condenser and the turbine.
  • the condenser is free to move longitudinally in the axis of the turbine and the forces due to atmospheric pressure pushing the condenser towards the turbine are compensated by articulated flying buttresses, arranged in parallel with said bellows, connecting the sleeve of exhaust to the condenser.
  • the present invention aims to ensure that the relative expansions between the turbine and the condenser do not cause reaction forces from the condenser to the turbine.
  • the invention thus relates to a connection device between a steam turbine and a condenser, the turbine being supported by a bearing on the intake side and a bearing on the exhaust side and being axially exhausted with a condenser at the end and comprising a sleeve.
  • this provision provides an additional advantage which is to allow the visit of the exhaust bearing of the turbine by accessing it by the axial tubular shell, open to the atmosphere whereas in the previous arrangement, such access requires a chimney access to the bearing which crosses the exhaust sleeve transversely, therefore in the passage of steam.
  • said turbine comprises an axial fixed point located at the level of the intake side bearing.
  • the condenser is linked to the ground.
  • the expansion of the condenser is carried out from a transverse key.
  • the assembly shown shows an axial turbine 1 and a condenser 2 located axially at the end of the turbine, beyond an exhaust sleeve 3 of the turbine and connected to this sleeve by an elastic seal. waterproof 4.
  • the turbine 1 is supported by blocks 5 and 6A, 6B at the level of the bearing on the intake side 7 and the bearing on the exhaust side 8 disposed in the exhaust sleeve 3, respectively.
  • the bearing on the intake side. 7 is rigidly connected to the turbine body by beams 9 and 10 and it rests on the block 5 by legs 11, 12 by means of pads 13, 14 resting on a sole 15 anchored in the massif 5.
  • the bearing 8, on the exhaust side is rigidly connected by support arms 18 to an internal ferrule 19 itself supported in the exhaust sleeve 3 by arms 20.
  • the exhaust sleeve 3 is fixed to the turbine body by a flange 21.
  • Figure 4 shows the parts of the bearing 8 on the exhaust side. It comprises a bearing body 22, a cap 23 and a stirrup 24 which holds the upper 25 and lower 26 bearings in place 26.
  • the shaft of the turbine rotor is seen.
  • the turbine is supported, as can be seen in the figures, at the level of the bearing 8 by lugs 28 and 29 by means of pads 30 and 31 resting freely on flanges 32 and 33 anchored in the solid masses 6A and 6B.
  • the turbine On the side of this exhaust end, the turbine is not axially fixed and it can expand freely by sliding on its pads 30, 31.
  • FIGs 1 and 2 there is shown schematically the last row of movable vanes 34.
  • the condenser 2 is connected to the ground by any means fixing its position, for example by a transverse key 35 allowing the free expansion of the condenser on the part and other of the key.
  • the condenser 2 is connected to the exhaust sleeve 3 by a tight elastic seal 4 clamped by jaws 36, 37.
  • the condenser is open and connected to a flange 38 by a second watertight elastic seal 39 clamped by jaws 40 and 41.
  • This flange has a circular orifice 42 and is fixed on the periphery of this orifice, to a end 43 of a tubular ferrule 44 which passes entirely through the condenser in the axis of the turbine and the other end 45 of which is fixed to the internal ferrule 19.
  • the ferrule 44 passes between two bundles 46 of tubes.
  • the first purpose of this ferrule 44 is to compensate for the force due to the atmospheric pressure which is exerted outside the turbine in the direction of the condenser 2.
  • This ferrule thus allows, thanks to its connection to the flange 38, of a diameter equal to the diameter of the right end of the exhaust sleeve and subjected to atmospheric pressure on its external face only, to exert a contrary force on the fixed parts of the turbine.
  • the condenser and the turbine are completely mechanically decoupled thanks to the seals 4 and 39 allowing their respective free expansion both vertically and axially and the forces due to atmospheric pressure are compensated by the flange 38 by l 'intermediate the ferrule 44 and the fixed parts of the bearing 8 linked to the exhaust sleeve 3 and therefore to the turbine stator.
  • the supports thus undergo no effort due to atmospheric pressure.
  • the ferrule 44 also provides additional advantages. Indeed, it allows access to the bearing 8 on the exhaust side without dismantling the body of the turbine and without requiring chimneys radially passing through the sleeve 3. The passage of steam is therefore not hindered. The ferrule also allows the passage of oil and steam piping.
