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 straight branches crimped at their ends in a tubular plate.
  • the straight branches of the tubes are held by spacer plates spaced along the length of the straight branches and through which the straight branches pass.
  • the tubes of the bundle are thus maintained in a regular arrangement in which the straight branches are all parallel to one another and the tubes arranged according to flat sheets parallel to each other in each of which the tubes whose curved parts have decreasing radii of curvature of the outside towards the inside of the sheet, are juxtaposed, the ends of the tubes of a sheet being engaged in a row of rectilinear openings crossing the tubular plate.
  • the tubes of the same layer and the adjacent layers are separated by free spaces of small width allowing the passage of the feed water of the steam generator inside the bundle, in contact with the external exchange surface. beam tubes.
  • each of the plies and which include the hangers with a smaller radius of curvature are aligned, so as to delimit between them a free space, the lower part of which above the tubular plate of the steam generator, constitutes the water generator steam street.
  • the curved parts of the tubes of each of the bundle plies have radii of curvature different and are juxtaposed so as to constitute a structure of substantially hemispherical shape called a bun, at the upper part 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 straight part of the tubes which is engaged in the spacers is effectively maintained by the spacers produced in the form of rigid plates.
  • 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 between the plies of adjacent tubes of the bundle and arranged in substantially radial directions of the bun.
  • anti-vibration bars as described for example in US-A-3,007,679 can be folded or assembled, so as to have the shape of a V whose two branches are directed in service along the radial directions of the bun between the layers of tubes of each of the pairs of adjacent layers.
  • the ends of the arms of the anti-vibration bars opposite their common ends are generally projecting from the tubes constituting the outer layer of the bun and connected together by curved bars resting on the outer surface of the bun on which are welded the outer end parts of the anti-vibration bars.
  • FR-A-91-14655 filed by the company FRAMATOME means of fixing the antivibration bars have been proposed to prevent their ejection outside the beam in the generator in service, which comprise an elongated structure fixed on the plate spacer 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.
  • V-shaped antivibration bars comprising as a whole six branches which must be placed in radial directions of the bun with a certain angular distribution.
  • the design and structure of the elongated fastening element are relatively complex because the steam generators comprise a large number of plies of tubes, this number being for example of the order of 130.
  • 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, spacer plates spaced along the length of the straight branches of the tubes and traversed by the straight branches maintaining the bundle tubes 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 plurality of anti-vibration bars interposed between the sheets of each pairs of adjacent plies of the tubes in their curved part, and means for fixing and connecting the antivibration bars comprising at least one elongated element fixed to the spacer plate closest to the curved parts of the tubes, in a direction perpendicular to the plies of tubes , inside a free space between the straight branches your tubes located at the central part of the layers, this heat exchanger comprising means for fixing the spacer bars of simple shape and allowing a simplified and faster assembly of the bundle.
