Definitions

  • the present invention relates to an overheating bundle for a horizontal steam separator-superheater, arranged in particular between two stages of an expansion turbine, comprising a network of parallel tubes arranged in a staggered mesh inside a shaped frame polygonal, symmetrical with respect to its plane of symmetry, delimiting in its lower part an orifice for access to the superheated steam and in its upper part an orifice for discharging the superheated steam.
  • the object of the present invention is to provide an overheating bundle for a horizontal vapor separator-superheater which has an homogeneous filling of the cross section of its frame and an optimal number of tubes per unit of cross section, and which avoids any tendency of the steam to be overheated to flow preferentially along its frame.
  • the beam according to the invention is characterized in that at least two of the oblique sides of the polygonal frame are parallel to the oblique segments formed by the mesh of the tubes.
  • the frame also preferably has two lateral vertical sides.
  • the lower or upper oblique sides of the frame advantageously end each in a short horizontal segment, and it is then arranged laterally and respectively above or below these segments of oblique sheets coming to bear tangentially on them, so as to oppose any circumvention of the frame of the tube bundle by the steam to be overheated.
  • This bundle is contained inside a rectangular frame whose side walls 1 and 2 are shown, rigidly connected to the shell of the separator-superheater, not shown.
  • the superheating tubes being a hairpin, are cut twice by the plane of the figure, or are therefore represented the elements of the upper 3 and lower 4 bundles.
  • These elements of the bundle each comprise a central beam 5, 6 coming to rest by its edges on lateral supports 7, 9 and 8, 10 respectively, integral with the lateral partitions 1, 2.
  • the elements of the bundle are contained in frames 3 and 4 of irregular hexagonal shape, having oblique sides 11, 13, 15, 17 and 12, 14, 16, 18 respectively, and vertical sides 19, 21, and 20, 22
  • These frames delimit passage openings lower and upper for the steam to be superheated through each of the elements of the bundle.
  • the oblique sides of the frame are parallel to the segments formed by the staggered tubes, so that the extreme rows of tubes are at a constant distance from the frame and that a maximum occupancy rate of the cross section of the frames is obtained by the tubes. This also avoids any preferential flow of steam along the frames, a source of heterogeneity in overheating.
  • the upper oblique sides 11, 13 of the upper frame 3 and lower 16, 18 of the lower frame 4 are extended by short horizontal segments 23 , 25 and 24, 26, to which tangentially oblique sheets 27, 29 and 28, 30 are connected, bolted to legs 31, 33 and 32, 34 welded to the lateral partitions 1, 2.
  • the invention applies in particular to separator-superheaters of power plants for production of energy and / or steam with multi-stage steam expansion turbines.

  1. Überhitzerrohrbündel für einen horizontalen Dampfabscheider-Überhitzer, mit einer Schar paralleler Rohre, die gemäß einer versetzten Ordnung in einem polygonalen Rahmen (3, 4) angeordnet sind, der bezüglich seiner Symmetrieebene symmetrisch ist und in seinem unteren Bereich eine Zugangsöffnung für zu überhitzenden Dampf sowie in seinem oberen Bereich eine Auslaßöffnung für überhitzten Dampf besitzt, dadurch gekennzeichnet, daß mindestens zwei der schrägen Seiten (11, 13, 15, 17; 12, 14, 16, 18) des polygonalen Rahmens parallel zu den schrägen Segmenten liegen, die von dem versetzten Netz der Rohre gebildet werden.
  2. Bündel nach Anspruch 1, dadurch gekennzeichnet, daß der Rahmen außerdem zwei vertikale Seitenwände (19, 21; 20, 22) besitzt.
  3. Bündel nach einem der Ansprüche 1 oder 2, dadurch gekennzeichnet, daß die unteren schrägen Seiten oder die oberen schrägen Seiten des Rahmens (15, 17; 16, 18) in kurzen waagrechten Segmenten (23, 25; 24, 26) enden und daß seitlich oberhalb und unterhalb der waagrechten Segmente schräge Bleche (27, 29; 28, 30) angeordnet sind, die tangential auf die waagrechten Segmente drücken und so jede Umgehung des Rahmens von Rohrbündeln durch den zu überhitzenden Dampf verhindern.
