Definitions

  • the invention relates to improvements in the production of water boxes for heat exchangers and in particular steam generators.
  • the tubes of the primary circuit each form a U, the ends of which are fixed to a tubular plate provided with two series of orifices corresponding respectively to the inlet and the outlet of the primary fluid.
  • the water box used for the supply and evacuation of the primary fluid is limited to its upper part by the tubular plate on which is fixed a hemispherical bottom separated into two parts by a semi-circular partition plate placed in a plane diametrical.
  • the water box is thus divided into two chambers, supply and discharge respectively, and the hemispherical bottom is therefore provided with pipes for connection of the pipes, respectively for the arrival and exit of the primary fluid.
  • the hemispherical bottom is also provided with manholes allowing access to each of the two chambers of the water box.
  • the tubular plate is made of carbon steel coated with stainless steel
  • the hemispherical bottom is of cast or forged steel
  • the partition plate is made of solid stainless steel.
  • the division of the hemispherical bottom into two chambers has another drawback. Indeed, it is sometimes necessary to access the interior of the water box for checking or maintenance operations. In this case, it is imperative to completely empty the water box of the contaminated water it contains. For this purpose, it is necessary, in each chamber to drill at the lower part of the hemispherical bottom of the bleed orifices which open into the inlet or outlet manifold of the primary fluid. But it is also necessary to drill other drain holes in the internal wall of the manhole so as to completely empty the space limited by the manhole closing plate and its cylindrical internal face placed in the thickness of the hemispherical background.
  • the partition plate fits with play over its entire periphery in a circular groove and a diametrical groove formed respectively on the internal walls of the hemispherical bottom and of the tubular plate and the hemispherical bottom is crossed by at least a purge orifice opening at the lowest point of the circular groove for fitting the plate, said orifice being capable of communicating with the two chambers of the water box.
  • the partition plate is mounted so as to be able to expand freely without interfering with the differential deformations of the tubular plate and of the hemispherical bottom. It has in fact been found that it is possible to keep the function of the separating plate of the water box into two chambers, by reducing by-pass to a minimum, without rigidly fixing it to the walls of the water box. In this way, the deformations of the water box are much easier to predict, and all the difficulties inherent in the production of welds are eliminated.
  • the water box is shown in section limited to its upper part by the tubular plate 1 and to its lower part by the hemispherical bottom 2.
  • the partition plate which has been removed in FIG. 2, divides the water box into two chambers 21 and 22, respectively for admission and discharge of the primary fluid. This circulates from one chamber to another in U-tubes not shown, the ends of which correspond to orifices 10 formed in the tube plate.
  • the hemispherical bottom is provided, for each of the chambers 21 and 22, with a tube 23 to which the primary fluid circulation pipe is connected and with a manhole 24 allowing access to the interior of the chamber corresponding.
  • FIG. 2 For the convenience of the drawing, there is shown in arbitrary positions, in FIG. 2, the supply tube 23 opening into the chamber 21 and a manhole 24 opening into the chamber 22.
  • the partition plate is shown from the front in FIG. 3. It has, conventionally, the shape of a semicircle, and as can be seen in FIG. 4, it is preferably provided with a thinning over its whole periphery. In this way, it can penetrate with play in the grooves made on the tube plate 1 and on the hemispherical bottom 2.
  • the upper groove 11 is constituted by a recess made in the underside of the tube plate, and in which engages the upper rectilinear edge 31 of the partition plate 3.
  • the circular groove may consist of two parallel ribs 25 spaced from each other by a distance substantially equal to the thickness of the partition plate 3 and welded to the hemispherical bottom 2.
  • the plate 3, penetrates with play between the two ribs 25.
  • the partition plate 3 is made to rest directly on the ribs 25, for example by means of shims. support 32.
  • the hemispherical bottom 2 is crossed at its lowest point, by an orifice 26 which opens in this way at the lowest point of the circular groove, between the two ribs 25.
  • These are provided with passages 27 which allow the orifice 26 to communicate with the two chambers 21 and 22 of the water box.
  • the partition plate 3 is independent of the walls limiting the water box. Indeed, it is simply supported on the hemispherical bottom 2 by the shims 32 and its upper part can slide freely inside the groove 11 of the tubular plate 1. Thus all the deformations and residual stresses due to the fixing by welding of the partition plate in the conventional embodiments. But in addition, the partition plate does not intervene in the deformations of the water box which can be calculated and therefore much easier to control.
  • the fitting of the partition plate facilitates docking of the bottom on the tubular plate.
