Definitions

  • the present invention relates to a device for suspending a bundle of horizontal tubes in a vertical plane, comprising pairs of vertical tubes provided with half-fins on their opposite sides, in particular for boilers for superheated steam generators. It also extends to a method of manufacturing this device.
  • a suspension device of this kind comprising a fin pierced with holes of diameter slightly greater than that of the tubes to be supported, at a pitch equal to that of the tubes of the bundle.
  • Each vertical tube thus comprises a half-fin, integral with that of the other vertical tube by bridges arranged between the successive horizontal tubes of the bundle, but the middle part of these bridges, in contact with the horizontal tubes at high temperature, and relatively distant from the two vertical tubes, is poorly cooled by conduction.
  • the bridges formed between the vertical tubes oxidize or corrode quickly, due to their high temperature in often corrosive gases.
  • this device is only applicable to heat exchangers with a single loop, without which the tubes could not be threaded individually in the holes of the fin.
  • the object of the present invention is to provide a suspension device which does not have a poorly cooled zone, and is therefore less exposed to corrosion, and which does not rigidly fix the tubes of the heat exchange bundle, so as to avoid welding cracks due to thermal stresses or vibrations.
  • the device according to the invention is characterized in that its half-fins have a profile comprising notches of circular shape, with a radius slightly greater than that of the tubes of the bundle, and of spacing equal to that of these tubes, separated by tongues of width large enough to ensure good support for the tubes of the bundle, but sufficiently small to ensure good thermal conduction from their edge to their zone of welding to the corresponding vertical tube.
  • the method of manufacturing the device of the invention is characterized in that at least one junction fin is welded between groups of vertical tubes, in that the fin is drilled with holes of diameter slightly greater than that of the tubes of the bundle to be supported, then in that the zones of the fin are cut between the holes parallel to the axis of the vertical tubes so as to eliminate them the middle portion of which the thermal conduction to the vertical tubes would be insufficient, without however ceasing to provide suitable support for the tubes of the bundle.
  • the fin is cut so that the middle portion of the latter thus eliminated is between 20 and 50% of the initial width of the fin.
  • junction fins are welded between the parallel vertical tubes, reserving an empty zone of lesser height between two fins, the vertical tubes are clamped in order to bring them closer to one another in this zone, and the they are welded to a horizontal spacer.
  • the superheater bundle 1 is arranged between vertical cooled screens 2 and 3. It is suspended from the pairs of vertical tubes 4, 5, .6, the latter being fixed at the top of the boiler in a manner not shown.
  • the vertical suspension tubes 7 and 8 are provided with half-fins in the zones 9 and 10 separated by the zone 11 where they are pinched towards one another and welded to a horizontal spacer.
  • bundle tubes such as 13, 14, 15 are arranged in notches of half fins welded to the vertical tubes, separated by tabs 16, 18, 20 on the side of the tube 7 and 17, 19, 21 on the side of the tube 8.
  • These notches have a radius of curvature slightly greater than that of the tubes 13, 14, 15, so that they can be inserted therein with a little play, but have a good surface. contact with the half fins welded to the vertical tubes.
  • the tongues 16, 18, 20, 17, 19, 21 do not have their internal edge too far from the corresponding vertical tube, so that they are well cooled by conduction from this tube.
  • Figure 3 shows on a larger scale the detail III of Figure 2.
  • the tongues 16, 18, 17, 19 have a width 1 between 25 and 40% of the width L separating the two vertical tubes.
  • the profile of the half fins welded to the vertical tubes is obtained by a cutting means which provides a regular profile, without sharp edges.
  • the invention applies first of all to superheater and reheater bundles of boilers subjected to corrosive combustion gases; it would also apply to horizontal bundles of tubes in contact with corrosive gases at high temperature, for example in the chemical industry.
