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 tightly welded pipes through which a medium flows, the pipes of the gas cable in the longitudinal direction of which and some of the wall pipes of the vertical throttle cable serve as support pipes and are connected at their upper ends to a supporting structure, whereas the pipes of the cross train - insofar as they run in the longitudinal direction - are bent outwards at their junction from their respective wall level and are led to collectors.
  • This object is achieved according to the invention in that in the region of the branching point of the cross train the wall pipes of the vertical throttle cable not serving as support pipes are bent outwards outside the cross train and are guided in groups to a vertical plane parallel to the longitudinal axis of the cross train in which the pipes of the relevant group - again bent and crossing the cross train - continued, the pipes being welded tightly at their penetration points to the wall of the cross train, and that at least the wall section of the vertical throttle cable, which is between the branch point of the cross train and the one in the throttle cable wall lying bending point of the wall tubes guided from below to the transverse cable is filled by appropriately curved wall tubes running in the longitudinal direction of the transverse cable.
  • 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 welded tightly 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. In FIG. 2, the support tubes are drawn thicker than the wall tubes 11 for better differentiation.
  • 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 wall tubes 21 run parallel to the longitudinal axis of the transverse cable 2. When they meet the walls 10 of the vertical gas cable 1, the wall tubes 21 of the two vertical walls 20 are bent horizontally outwards 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 11 aligned with it in the wall 10.
  • the webs 33 of the two horizontal walls 20 are continued seamlessly in the vertical walls 10 of the throttle cable 1, with the same web width in that wall 10, the plane of which forms a right angle with the longitudinal axes of the wall tubes 21, and narrower web width in the two walls 10, the plane forming with the longitudinal axes of the striking they wall tubes 21 a 90 0 angle different.
  • the webs 33 from the horizontal walls 20 are tightly welded to the webs 3 originating from the walls 10 at the bending point of the tubes 11.
  • the vertical sections 21 'of the wall pipes 21 are 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 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 cross train 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 tubes 11 of the vertical gas cable 1 penetrate the two horizontal walls 20 in their further course of the transverse pull 2, namely the puncture points of a group each lie in a web 33 between two wall tubes 21.
  • the sections 11 ′′ are welded to the webs 33 in a gas-tight manner. 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. 2 and labeled 21 ", are bent out of the horizontal wall 20 before they meet the relevant support tubes 12 - that is, outside the vertical throttle cable 1 - and up to their next turning point guided parallel to the support tube 12. On their way to the collector 24, the tubes 21 "are again guided around the vertical sections 11"'.
  • the flow of the gas acting on the gas passages 1 and 2 is - regardless of its direction of flow - practically undisturbed. Since all the tubes crossing the space 23 are arranged one behind the other in the direction of flow, the disturbance caused by them in the gas flow is essentially identical to the disturbance which the support tubes would cause anyway and which is known to be negligible.
  • the distance, on which the wall pipes 11 are routed outside the gas passages and on which they do not participate in the heat exchange with the flowing gas is compensated for by the fact that these pipes are fully immersed in the gas flow as they pass through the transverse passageway 2 and with their entire circumference Participate in heat exchange instead of only part of the circumference, as is the case with the course in the walls 10.
  • 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 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 .
  • 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 of the transverse pull 2, not shown, is carried out e.g. by means of supporting frames which are attached to a supporting frame.
  • 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.
