Definitions

  • the present invention relates to a concrete condenser for an axial exhaust steam turbine carried by a concrete slab comprising several bundles of tubes.
  • Such a condenser is known from document FR-A 2651276.
  • the beams are mounted by means of vertical internal tie rods suspending the beams from the walls of the condenser. But the presence of these tie rods is very troublesome for the circulation of steam.
  • GB-A-1015052 describes a capacitor comprising a bottom wall constituting the raft, side walls, superimposed bundles of tubes, these bundles comprising two vertical end tubular plates integral with the side walls and intermediate vertical tubular plates integral with, and resting on the raft.
  • This capacitor does not make the beams independent of the concrete enclosure, in addition the beams cannot be dismantled independently.
  • the assembly of the bundles according to the invention is done so as to make them, for the most part, independent of the enclosure of the condenser, which facilitates maintenance and in particular the changing of the bundles.
  • the invention relates to a concrete condenser for an axial exhaust steam turbine, carried by a concrete slab, the condenser comprising a bottom wall formed by the slab, side walls, several superimposed bundles of tubes, each bundle comprises two vertical end tube plates and intermediate vertical tube plates.
  • the vertical tubular end plates are connected by flexible seals to the side walls of the condenser, the plates are joined together by tie rods and support, at free expansion, the bundle tubes, the plates intermediates located near the end plates being supported by internal steel supports fixed to the side walls of the condenser.
  • One of the intermediate plates supported by an internal steel support is provided at its base with an elastic stud allowing a longitudinal displacement.
  • the other plate is fixed on its internal steel support.
  • the condenser comprises concrete piers internal to the condenser and carried by the slab supporting the intermediate plates of the bundles located near the slab.
  • the bundles are self-supporting and freely expandable.
  • Figure 1 shows an axial exhaust turbine with a concrete condenser located in its extension.
  • Figure 2 shows in section a first embodiment of the condenser according to the invention.
  • Figure 3 shows in section a second embodiment of the condenser according to the invention.
  • the steam turbine 17 comprises an axial exhaust 18 forming part of the stator 19 (see FIG. 1).
  • a concrete condenser 23 is located in the extension of the exhaust 18. It comprises an enclosure 1, the bottom wall is formed by the raft 6.
  • the front wall of the enclosure 1 corresponds to the connection sleeve of the turbine 17 with the condenser 23. It is in the form of a truncated pyramid.
  • the side walls are provided with openings 2 to let the ends of several bundles of superimposed tubes pass. These bundles are provided with water boxes 12, 13 at each end.
  • the tube bundles are located on either side of the extension of the axis of the turbine.
  • the tubes 5 of the superposed bundles 4, 4 ′ are mounted for free expansion in vertical tubular plates 7 and in vertical tubular end plates 8.
  • the bundles are located in the extension of the turbine so that the steam strikes after a medium straight stroke the bundles 4, 4 '.
  • Walls of the enclosure 1 are provided below the openings 2 with steel supports 11 carrying the vertical tubular plates 7 close to the end plates 8.
  • the periphery of the openings 2 is connected to the end plates 8 by a flexible seal 10 of U-shaped section.
  • the water boxes 12, 13 are fixed to the end plates 8.
  • Elastic pads 15 are arranged at the base of the plates 7 supported by the concrete piles 14, one of the plates 7 near one of the end plates is also provided at its base with an elastic pad 15.
  • the other plate 7 is fixedly mounted on its support 11. Thanks to these elastic studs 15 the bundles 4 and 4 ′ can expand longitudinally
  • 4 'of the tie rods 16 are arranged between plates 7 of the top beam 4' and the plates 7 of the bottom beam 4 to adjust the natural frequencies of the assembly.
  • the water boxes are made of concrete and are attached to the walls of the enclosure.
