Definitions

  • the present invention relates to steam condensers. It is known that a steam condenser for a power plant is constituted by a set of tubes joined at each of their ends by a tubular plate, the whole being placed in a condenser body joined to the exhaust of the turbines and a box water being attached to each tube plate.
  • Figures 1 and 2 thus show a known embodiment, produced at the San Onofré power plant in the United States in California, of a steam condenser in which the tube bundle, comprising tubes 1 and two tube plates 2 and 3 , is produced in the factory and then assembled, on site, to the condenser body 4.
  • the tube bundle is made up of four modules assembled at the time of assembly.
  • Part 6 has four windows shown in Figure 2 and is used to assemble the modules.
  • the tubular plate 3 of each module is connected to a frame 8 by means of screws 9: to each frame 8 are pieces 10 and 11 welded on the appropriate faces so as to close the body condenser.
  • the water box 12 on the left ends with a plate 13, the shape of which is also shown in FIG. 2. This plate is used to assemble the four tubular plates 3.
  • each module comprises on the right only the tube plate 2 and on the left, in addition to the tube plate 3, the parts 8, 10 and 11.
  • the module thus composed is introduced from the right towards the left through one of the four windows of the part 6 until the tube plate 2 abuts against the part 6, by means of a seal 18.
  • the assembly is then fixed by means of screws 15 and the weld 17 is made which connects the plates 11 to the body 4.
  • the water box 12 is fixed 13 by means of screws 16.
  • Seals 18 and 19 are placed respectively between the tube plate 2 and the part 6 and between the tube plate 3 and the frames 8, and a seal 14 is also placed between the frame 13 and the tube plate 3.
  • the present invention aims to overcome these drawbacks and to provide a more satisfactory, more practical and safer solution.
  • the subject of the invention is therefore a modular tubular bundle for a steam condenser comprising two tubular plates, a series of tubes connecting the two tubular plates and a set of support spacer plates distributed between the two tubular plates, characterized in that the two plates tubulars have the same dimension, each being surrounded by a thicker reinforcement frame than said tubular plate and in that tie rods, provided with means for adjusting their length, join the two tubular plates, said tie rods being fixed on said frames and distributed along the frames.
  • the invention also relates to a steam condenser comprising a casing containing a tubular bundle associated at each end with a water box, characterized in that said tubular bundle is produced by the parallel assembly of n said modular tubular bundles.
  • the assembly of the n modular tubular bundles is carried out at each end of the assembly to be connected, by means of an assembly flange with n windows, bearing against the reinforcing frame of each modular bundle, on the external side with respect to the tubes and fixed to these frames, the external perimeter of the flange having an external rim extending beyond the external perimeter of the assembled tube bundle, said flange being fixed along said outer edge against a flange fixed to said casing of the condenser, the passage dimension inside said flange being identical on each side of the condenser.
  • FIG. 3 thus shows a modular tubular bundle according to the invention. It comprises two tubular plates 20 and 21, a set of tubes 22 and a set of support spacer plates 23. Each tubular plate is surrounded by a reinforcing frame: 24 for the tubular plate 20 and 25 for the tubular plate 21. These frames reinforcements are welded to their respective tube plate. Finally, a series of tie rods 26 connect the two plates and, thanks to a means for adjusting their length, shown in enlarged view in FIG. 4, adjust the spacing of the plates exactly. The tie rods are spaced approximately 500 mm apart. At least some of the support spacer plates 23 are connected to the tie rods 26 to increase the rigidity of the assembly.
  • the adjustment system comprises a sleeve 27 having a bore passing right through it and tapped on one side with a pitch to the right and on the other with a pitch to the left.
  • the tie rods 26 are in two parts 26a and 26b which are screwed into the sleeve. Nuts 28, mounted at the ends of the tie rods, block their screwing in the tubular plates.
  • the frames 24 and 25 and the tie rods 26 and the support spacer plates 23 provide the assembly with excellent rigidity.
  • the module is symmetrical, the tubular plates having the same dimension on the right and on the left.
  • FIG. 5 shows the way in which a module, such as that shown in FIG. 3, is assembled with three other identical modules, the whole being mounted in a condenser jacket.
  • the condenser comprises an outer shell 29 partially shown.
  • a flange 30 is welded to the casing so as to allow all of the four assembled modules to be fixed in the casing.
  • This figure 5 represents only a small part but the whole is symmetrical, the assembly being identical on the right and on the left as well as above and below.
  • the modules are assembled together by means of a flange 31 bearing on the four frames 25 of the four modules that we want to assemble.
  • FIG. 6 shows the geometry of this flange 31.
  • the fixing is carried out by means of studs 32 passing through holes 32a of the flange 31, and nuts 33.
  • Two seals 34 and 35 are interposed around the periphery of each frame 25 of each module between the flange 31 and the respective frames 25.
  • support bars 36 are interposed all along the flange in 500 mm sections between the nuts 33 and the flange 31.
  • the external perimeter of the flange 31 carries an external extension 37 extending beyond the external perimeter of the complete tubular bundle assembled so as to fix the assembly against the flange 30 by means of threaded rods 38 passing through holes 38a of the flange, and of nuts 39 and 40, fixing at the same time the water box 41 provided with an assembly flange 42.
  • Two seals 43 and 44 are interposed between the outer edge 37 of the flange 31 and the flange 30.
  • a support frame 45 and a seal 46 are interposed between the flange 42 and the flange 31.
  • FIG. 7 is an enlarged view of the surrounded part VII of FIG. 5.
  • FIG 8 shows a variant of Figure 7 in which the seals 34. 35 are protected by a hydraulic barrier.
  • each reinforcing frame 25 has a counterbore 47 over its entire periphery, this counterbore being connected by a channel 48 and 49 to a water inlet not shown at a pressure higher than the cooling water arriving in the box. water 41 ( Figure 5).
  • the support plates 36 are then replaced by thick washers 50, individual. Seals 51 and 52 are interposed between the flange 31 and the washers 50 and between the washers 50 and the rods 32.
  • the flange 31 is fixed to the frames 25 of the modules by screwing means, which constitutes a preferred embodiment.
  • screwing means which constitutes a preferred embodiment.
