Definitions

  • the invention relates to a heat exchanger comprising a bundle of U-bent tubes and anti-vibration bars between the bent parts of the tubes.
  • the invention applies in particular to a steam generator of a pressurized water nuclear reactor.
  • the steam generators of pressurized water nuclear reactors comprise U-shaped bent tubes having two parallel straight branches crimped at their ends in a tubular plate.
  • the tubes of the bundle are thus maintained in a regular arrangement in which the straight branches are all parallel to each other and the tubes arranged in flat sheets parallel to each other in each of which the curved parts of the tubes have decreasing radii of curvature from the outside towards the inside of the sheet.
  • the curved parts of the tubes of each of the layers of the bundle have different radii of curvature and are juxtaposed so as to constitute a structure of substantially hemispherical shape called a bun, at the top of the bundle of the steam generator.
  • pressurized water at high temperature circulates in the bundle tubes and drinking water is brought into contact with the external exchange surface of the tubes along which it moves in the vertical direction by heating and then vaporizing, to come out as vapor at the top of the steam generator.
  • the circulation of fluids in contact with the tubes can cause vibrations which are likely to cause damage to the tubes if they are not maintained effectively.
  • the right part of the tubes is engaged in spacers located at regular distances from each other according to the height of the beam. These straight parts are therefore effectively maintained by rigid elements.
  • the curved parts of the tubes of the bundle constituting the bun must also be maintained and generally used for this purpose anti-vibration bars which are interposed each between two plies of adjacent tubes of the bundle and arranged in substantially radial directions of the bun. These anti-vibration bars as described for example in patent US-A-3,007,679 are generally connected two by two of their ends inside the bun and placed angularly to form V-shaped structures.
  • the outer ends of the antivibration bars opposite their central part project from the tubes constituting the outer layer of the bun and are interconnected by connecting means ensuring the maintenance of the antivibration bars.
  • a wedging device comprising connecting means between the outer ends of anti-vibration bars arranged in sets of at least two bars in which the bars are aligned and have aligned through openings, one of which is tapped.
  • the connecting means of the anti-vibration bars comprise a pin which is inserted into the aligned openings of the set of anti-vibration bars and into the bore of spacers which are each inserted between two successive anti-vibration bars.
  • the spindle which has a threaded end is screwed into the tapped opening of an anti-vibration bar located at the end of the row.
  • the spindle is also secured to a rotation blocking element which can be welded to a spacer.
  • a rotation blocking element which can be welded to a spacer.
  • an anti-vibration wedging device comprising connecting means between the outer ends of the anti-vibration bars arranged in sets of at least two bars in which the bars are aligned and comprise aligned through openings.
  • the connecting means between the ends of the anti-vibration bars include a screw whose head is intended to come to bear on a first anti-vibration bar and whose threaded rod is screwed into a spacer.
  • the spacer is fixed either in a second spacer, or in a threaded fixing element, by a threaded part. The threaded parts of the screw and the spacer pass through the anti-vibration bars through aligned openings.
  • All anti-vibration wedging devices comprising anti-vibration bars require an anti-take-off device to keep them inside the bun.
  • Anti-theft stirrups are also used in patents FR 2 644 281, FR-A-2 664 965 and FR 93 / 12.514, their fixing being ensured by mechanical means in order to avoid welding.
  • the anti-take-off stirrups have the drawback of maintaining the anti-vibration device, by making the retaining force bear on certain tubes of the bundle, the tubes being a sensitive element in the operation of the steam generator, we therefore sought to carry out the restraint effort from elements other than the tubes
  • FR-A-91-14655 filed by the company FRAMATOME means of fixing the anti-vibration bars have been proposed to prevent their ejection outside the bundle in the steam generator in service, which comprise an elongated structure fixed on the spacer plate of the steam generator closest to the curved parts of the tubes constituting the bun.
  • the elongated structure generally constituted in the form of a rail is fixed on the upper face of the spacer plate, in a direction perpendicular to the plies of tubes, inside the central free space constituting the water street of the generator. steam.
  • the elongated fixing structure comprises, at each of the spaces between two pairs of plies of adjacent tubes, at least one notch in which the internal part of the anti-vibration bar can be engaged.
  • This anti-theft device while eliminating the aforementioned drawback of making the effort bear retained on the tubes, requires during assembly operations a fairly long installation, taking into account the positioning of the anti-vibration bars in a large number of notches and does not ensure complete support in position of the anti-vibration device.
  • the object of the invention is therefore to propose a heat exchanger comprising a bundle of U-bent tubes so as to have two straight branches and a curved part between the two straight branches, the bundle tubes being located in a regular arrangement in which the straight branches are all parallel to each other and the tubes arranged in planar plies parallel to each other, a bundle envelope surrounding the bundle of tubes, a plurality of anti-vibration bars interposed between the adjacent plies of the tubes in their curved part, to present an end outside the bundle, connecting means between the outer end parts of the anti-vibration bars and an anti-take-off device which does not bring the retaining force onto the bundle tubes, which is d '' simpler mounting than known devices and which ensures complete retention of the anti-vibration bars ires and their means of connection.
  • all of said connecting means is connected to at least one support integral with the bundle envelope so as to constitute the anti-theft device of the anti-vibration bars allowing limited movement of the set of anti-vibration bars and of their connecting means in a direction parallel to the straight branches of the tubes.
  • Another object of the invention is to provide a heat exchanger comprising a bundle of U-bent tubes so as to have two branches straight and a curved part between the two straight branches, the tubes of the bundle being located in a regular arrangement in which the straight branches are all parallel to each other and the tubes arranged in flat sheets parallel to each other, a bundle envelope surrounding the bundle of tubes, a plurality of anti-vibration bars inserted between the adjacent plies of the tubes in their curved part, so as to present an end outside the bundle and connecting means between the external end parts of the anti-vibration bars in a plurality sets of at least two bars in which the bars are aligned, designed to limit the number of connecting pieces and to facilitate assembly.
