Definitions

  • the invention relates to a vertical throttle cable according to the preamble of claim 1.
  • Such a gas train for a steam generator is known from FR-A-1 416 901.
  • the throttle cable has a square or octagonal cross section and the horizontal funnel outlet opening is square in both cases.
  • the wall pipes of the throttle cable are bent into inclined funnel walls at the boundary edge and guided parallel to each other within an inclined funnel wall.
  • the tubes are bent outwards from these walls because, for reasons of space, they cannot be led to the funnel outlet opening.
  • the pipes led out of the sloping funnel walls are then forked together in pairs and open into collectors parallel to the square outline of the funnel outlet opening.
  • the invention is therefore based on the object of improving the funnel construction in the case of a throttle cable of the type mentioned at the outset in such a way that bending out of funnel wall pipes between the boundary edge and the funnel outlet opening is avoided and that when using the throttle cable for large steam generators, the commercially available facilities for disposal are retained residues accumulating in the funnel is possible.
  • a vertical throttle cable 70 is in the form of a prism with twenty-four identical sides, which is formed by wall tubes 2 which are sealed to one another and carry a medium and likewise vertical, by means of webs 3.
  • a funnel 40 connects along a boundary edge 14, the outlet opening 44 of which has a long, rectangular shape.
  • the funnel 40 consists essentially of six flat walls 41, 42 and 43.
  • the two vertical walls 41 delimit the short side of the outlet opening 44, whereas the two inclined walls 43 extend along the long side of the opening 44.
  • the two inclined walls 42 connect the throttle cable wall with a vertical wall 41 along a horizontal edge 24.
  • the six walls 41, 42 and 43 are also formed by extensions of the wall tubes 2 and the webs 3, which are also tight in the funnel 40 with the tubes are welded.
  • the tubes are bent at the boundary edge 14 or at the edge 24.
  • the boundary edge 14 has a broken course, which depends on which side of the throttle cable 70 meets it with the funnel. If the boundary edge 14 is perpendicular to the longitudinal axis of the wall pipes 2 running in the gas pass 70, the pipe division in the adjoining wall section of the funnel 40 remains the same. The more the angle between the boundary edge 14 and the longitudinal axis of the wall pipes 2 in the throttle cable 70 deviates from the right angle, the narrower the division of the pipes 2 bent into the funnel wall in this wall part of the funnel 40.
  • a vertical ideal reference plane e1 Between the two vertical walls 41, parallel and symmetrical to them, is a vertical ideal reference plane e1 and, at right angles to it, a vertical ideal reference plane e2, which divides the vertical walls 41 into two equal parts. All wall tubes 2 in the two inclined walls 43 run parallel to the reference plane e1, the number of tubes on both sides of this plane e1 being the same. Likewise, all the wall tubes 2 in the two vertical and sloping walls 41 and 42 run parallel to the reference plane e2, the number of tubes again being the same on both sides of this plane e2.
  • the funnel 40 is reinforced by means of a special support structure 50 (FIG. 2), which absorbs mechanical loads, in particular bending loads on the sloping walls 43, and thus maintains the shape of the funnel 40.
  • the support structure is slidably connected to the funnel walls.
  • the support structure 50 has two support grids 51, each of which is composed of inclined supports 52 and horizontal supports 53.
  • the support structure 50 has a support ring 54, which is fixedly connected to the two support grids 51 at the upper end, and a plurality of auxiliary supports 55.
  • the support grids 51 run parallel to the inclined walls 43 and are pivotally mounted at their lower ends in the region of the outlet opening 44 about an axis 58 each.
  • the support ring 54 is dimensioned according to a previously calculated deformability so that it has the shape of an ellipse in the unloaded state, the major axis of which runs approximately parallel to the longitudinal direction of the outlet opening 44, has a circular shape in normal operation and, under very heavy loads, e.g. B. in the case of explosions inside the funnel, takes the form of an ellipse, the major axis of which is then perpendicular to the longitudinal direction of the outlet opening 44.
  • the auxiliary supports 55 are provided which are connected to these walls in a known manner in such a way that mutual freedom of movement in the horizontal direction is ensured, both under loads and under thermal expansion.
  • the support ring 54 On the support ring 54 four claws 56 are attached distributed over its circumference, each of which is guided between two vertical guide plates 57 of a support frame, not shown. The interaction of the claws 56 with the guide plates 57 enables the support ring 54 to carry out vertical movements and deformations along two axes, one of which is parallel and the other perpendicular to the longitudinal direction of the outlet opening 44; however, horizontal displacements of the support ring 54 are prevented.
  • the throttle cable 70 and the funnel 40 are connected to the support ring 54 by means of tab systems, not shown, which are known per se and which permit both vertical movements of the support ring 54 and different thermal expansions of the parts connected to one another, but larger deflections of the gas cable 70, e.g. B. in the event of an earthquake, prevent.
  • the two vertical walls 41 of the funnel 40 are reinforced in addition to the auxiliary supports 55 by tension bands 59, which are connected to the funnel corners by means of tabs 59 'with the support grids 51 to connect the support structure 50 to the funnel 40 in its lower region are connected.
  • the supporting grids 51 are provided at their lower ends with joints 58 ′ which contain the pivot axis 58 and are attached to two horizontal supports 46 which run parallel to the longitudinal direction of the outlet opening 44. As a result, they can pivot somewhat about the associated axis 58 in order to compensate for thermal expansions of the funnel 40 or deformations therein as a result of internal stress, the support ring 54, as already mentioned, being slightly deformed.
  • FIG. 4 shows how the wall tubes 2 are bent to provide space for to create the known link connection between the carriers 46 on the one hand and the drawstrings 59 "on the other; this also applies to the tab connections between the tension bands 59 and the support grids 51.
  • the support structure 50 can have a very different temperature from the funnel 40, but this does not have a disruptive effect because of the measures described to compensate for different thermal expansions.
  • the support structure 50 also has sufficient flexibility to absorb mechanical loads caused by deformations of the walls 51.
  • the sloping walls 42 are not specially reinforced due to their small size and their favorable shape.
