Definitions
- the invention relates to a turbine and condenser assembly according to the preamble of claim 1.
- Such an assembly is known from document SU-A-116 919.
- This known condenser comprises bundles of tubes which are situated below the axis of the turbine and the bearing is situated above the condenser. It follows that the condenser expansions act on the turbine shaft.
- the condenser as defined by claim 1 attached does not have these drawbacks.
- Figure 1 shows in section an axial exhaust turbine with its condenser according to the main claim.
- Figures 2 and 3 show two perspective views of the turbine and the condenser according to the main claim.
- Figure 4 shows the turbine of Figure 1 in back view.
- Figures 5 and 6 show a variant of the turbine of Figure 1 in side view and in back view.
- the turbine 1 has an axial exhaust 2 forming part of the stator 3.
- the condenser 5 comprises a rectangular parallelepipedic outer casing 6 located in the extension of the exhaust 2.
- the lower wall 7 of the condenser is formed by the raft 4. It is located below the lower part of the turbine 1.
- the front wall 8 corresponding to the condenser turbine connection sleeve is in the form of a truncated pyramid.
- the turbine side part is provided with a circular flange 9 on which the flange 10 of the turbine is fixed located at the rear of the exhaust 2.
- the front wall 8 joins the side walls 11 and the lower wall 7 and upper 12 of the condenser.
- the side walls 11 are provided with openings 13 through which the bundles of tubes 14 pass through which the cooling water passes. Lines 15 serve to bring and evacuate this cooling water.
- the rear wall 16 is provided with concrete supports 17 on which the heaters 18 are arranged.
- a heat shield 19 Inside the condenser along the concrete walls is arranged a heat shield 19.
- the rotor 20 of the turbine is supported by two bearings 21 and 22, one located on the intake side, the other in the axial exhaust 2 of the turbine 1.
- the bearing 21 is supported by a concrete support 23 integral with the concrete slab 4. It includes a stop 37.
- the bearing 22 includes a bearing 24 on which are fixed a stirrup 25 and a lining 26.
- the lining 26 is brought to atmospheric pressure by pipeline 27.
- a vertical concrete wall 28 is provided, integral with the raft 4 and comprising a semicircular cradle 29 in which the lower part of the exhaust 2 is housed.
- the bearing 22 is supported by four radiating tie rods 30 and located in a vertical plane perpendicular to the axis of the rotor. Two tie rods are horizontal and the other two are directed downwards and spaced at an angle of 60 ° with the neighboring tie rods.
- the tie rods 30 are anchored at their ends in the thickness of the wall 28 around the cradle.
- the tie rods 30 are provided with sealing bellows 31 at their crossing of the wall of the exhaust 2.
- the exhaust 2 is provided with two lateral legs 32 which rest on two concrete supports 33 integral with the raft 4.
- the exhaust centering device 1 comprises a key 34 mounted on a concrete support 35 integral with the raft 4, said key 34 being trapped in a slide 36 parallel to the axis of the turbine and integral with the exhaust 2.
- the supports 23, 33, 35 and the wall 28 are preferably made of concrete and are directly integrated into the raft and constitute with the raft 4 a solid.
- the condenser turbine connection is made via the flanges 9 and 10.
- the bottom effect is taken up by the exhaust 2 of the turbine 1 and the outer casing 6 of the condenser.
- the starting point of the axial expansions of the stator 3 of the turbine 1 is the plane of the flange 9.
- the stator 2 can drive the stop 37 in the bearing 21 to minimize the differential expansions of the rotor 20 stator 2.
- a monolithic set of concrete was thus obtained from the base 4 of the turbine, the external envelope 6 of the condenser 5 and the support 17 of the heaters 18.
- connection between turbine 1 and condenser 5 is very simple (bolted flanges) and it is no longer necessary to provide supports and means for guiding the condenser.
- Figures 5 and 6 relate to a variant of the turbine described in more detail in French patent application No. 8905544 in the name of the applicant which is included in this application.
- the vertical concrete wall 28 is the starting point of the concrete structure of the condenser as described above. It is provided with a circular opening 29 ′ on which the exhaust 2 of the turbine 1 is fixed.
