Definitions

  • the invention relates to a heat exchanger, in particular a steam generator, with a vertical throttle cable and with at least one cross cable branching from it, the boundary walls of both the gas cable and the cross cable consisting of wall tubes tightly welded to one another and through which a medium flows, the wall tubes of the gas cable in its longitudinal direction and some of the wall pipes of the throttle cable serve as support pipes and are connected at their upper ends to a supporting frame, whereas the wall pipes of the cross train - insofar as they run in the longitudinal direction - are bent outwards and out at their branch point from their respective wall level Collectors are led.
  • connection has good bending flexibility, which allows deformations, which are caused, for example, by different thermal expansions of the gas flues or by earthquakes, to be compensated for without further ado.
  • Another additional advantage is the fact that it can be used on throttle cables of all possible shapes, for example on throttle cables with a polygonal or cylindrical cross section. It also allows perfect connections between throttle cables of different cross-sectional shapes.
  • the features of claim 7 represent a different type of formation of the penetration points in the walls of the cross train.
  • the design of the wall pipes of the two throttle cables according to claim 8 leads to a particularly good and clear connection of the walls of the cross train with the walls of the vertical throttle cable.
  • the throttle cable 1 branches off from a vertical, hexagonal cross-section throttle cable 1 a horizontal, rectangular cross-section cross cable 2, namely near the upper end of the throttle cable 1.
  • the two cables 1 and 2 enclose a space 13 and 23.
  • the boundary walls 10 of the throttle cable 1 consist of vertically extending wall tubes 11 which are tightly welded to one another via webs 3.
  • support tubes 12 are provided instead of wall tubes, which can have the same diameter as the wall tubes 11.
  • the support tubes for better differentiation from the wall tubes 11 are drawn thicker than these.
  • the vertical throttle cable 1 is suspended from a support frame (not shown) by means of the support tubes 12.
  • the support tubes 12 run through the opening connecting the rooms 13 and 23, whereas the wall tubes 11 are bent outwards from the walls 10 shortly before the cross train 2 meets and initially along a short horizontal distance parallel to the wall
  • the longitudinal axis of the transverse train 2 run (section 11 'in Fig. 2).
  • the short distances are different for the individual pipes.
  • the tubes are then bent again horizontally (section 11 ′′ in FIG. 2) and guided up to a vertical plane, which in each case contains the longitudinal axis of a support tube 12 crossing the transverse train 2 and extends parallel to the longitudinal axis of the transverse train.
  • the four walls 20 delimiting the transverse train 2 consist of wall tubes 21 which have the same diameter as the wall tubes 11 and are also welded tightly to one another via webs 33.
  • the wall tubes 21 run parallel to the longitudinal axis of the transverse cable 2.
  • the wall tubes 21 of the two vertical walls 20 are bent horizontally outwards when they meet the walls 10 of the vertical gas cable 1 and open into a vertical collector 25 at each wall. At the bending point of the tubes 21 of the vertical walls 20, these tubes are welded gas-tight to the relevant wall 10.
  • the wall tubes 21 of the two horizontal walls 20 are bent such that they continue vertically from this turning point in the wall 10 in question (section 21 "') to close to the turning point of the tube aligned with it 11 in the wall 10.
  • the webs 33 of the two horizontal walls 20 are also continued seamlessly in the vertical walls 10 of the throttle cable 1, with the same web width in that wall 10 whose plane forms a right angle with the longitudinal axes of the wall tubes 21, and with a narrower web width in the two walls 10, the plane of which forms an angle different from 90 ° with the longitudinal axes of the wall tubes 21 which meet them.
  • the webs 33 from the horizontal walls 20 are at the bending point of the tubes 11 with those from the walls 10 originating webs 3.
  • the vertical sections 21 'of the wa are removed about 0.5 of the web width from the bending point of the tubes 11 nd pipes 21 bent outwards and guided parallel to the sections 11 'of the wall pipes 11 to an upper or lower horizontal collector 24.
  • the sections 21 'with the webs 33 located between them thus fill the part of the walls 10 which lies between the bending points of the tubes 11 and the branching point of the transverse pull 2.
  • This configuration of the transition from the throttle cable 1 to the transverse cable 2 results in an excellent connection in terms of strength between the walls 10 and the horizontal walls 20.
  • the vertical sections 11 "'of the wall pipes 11 of the vertical throttle cable 1 penetrate the two horizontal walls 20 of the transverse cable 2 in their further course, namely the points of intersection of a group each lie in a web 33 between two wall pipes 21.
  • the sections are at the points of intersection 11 "'welded gas-tight with the webs 33. Since the sections 11 "'are aligned with the associated support tube 12, they would have to meet a tube 21 in the horizontal wall 20 in a straight line. In order to avoid this, each wall tube 21 running towards a support tube 12 is around the piercing points of the sections 11". 'led around. In addition, these tubes, one of which is shown on the right in FIG.
  • the wall pipes 11 of the vertical throttle cable are bent alternately on two different height levels - labeled B and C in FIGS. 3 and 6 - on both sides of the branching point of the cross cable.
  • the sections 21 'of the wall tubes 21 of the two horizontal walls 20 of the cross train are also alternately bent on both sides of the branch point at two different height levels - designated D and E in FIGS. 3 and 6 - from the walls 10 of the vertical throttle cable. From FIG. 4, better than from FIG. 2, it is possible to see the wall tubes 21 "running towards each support tube 12 around the intersection points of the sections 11" '.
  • the tubes 21 "are led outside the planes D and E to the collector 24. In the embodiment according to FIGS. 3 to 6, excessively large web areas and thus the generation of high thermal stresses are avoided.
  • the upper horizontal wall 20 of the transverse cable 2 can instead of being bent upwards be continued in a straight line in order to form the upper end of the vertical gas cable 1.
  • the vertical sections 11 "'of the wall pipes 11 are not led back to the wall 10 of the vertical throttle cable 1 after leaving the transverse cable 2, but rather directly into a collector into which the other wall pipes 11 which are not guided by the transverse cable also open can.
  • the support, not shown, of the transverse pull 2 takes place, for. B. by means of supporting frames which are attached to a supporting structure.
  • the two vertical walls 20 of the transverse train can be provided with pipes running transversely to the longitudinal direction instead of with pipes running in the longitudinal direction thereof.
