Definitions

  • the present invention relates to a food water heater comprising a desuperheating zone, in particular for a thermal electric power station.
  • the water supplying the boiler passes through a series of heaters generally consisting of a tube bundle, an outer casing and water boxes or collectors.
  • the heating steam enters the envelope around the tube bundle where it eventually condenses, giving up its heat to the food water passing through the tubes.
  • the entry and exit of the steam in the desuperheating zone are particularly delicate places because they are very localized and have a reduced section, which involves an impact by the steam which can be dangerous for the tubes are subjected to it (vibrations , erosion).
  • the present invention aims to provide a food water heater comprising a desuperheating zone which does not have the drawbacks of the prior art.
  • the subject of the present invention is a food water heater comprising a box for desuperheating steam traversed longitudinally by a bundle of tubes traversed by food water, characterized in that the box comprises a steam inlet s extending almost over the entire length of the desuperheating chamber and a steam outlet extending on the lateral side opposite the steam inlet and over an equivalent length.
  • the vapor path thus takes place orthogonally to the tubes passing through the box.
  • the guiding of the steam in parallel currents can also be ensured by integral plates supporting the tubes, arranged orthogonally to these tubes and occupying substantially the entire cross section of the box, without this causing pressure losses. additional. Moreover, the support plates can be brought together without increasing the speed of the vapor, this being conditioned by the total length of the box.
  • the heater is also advantageous for the heater to be free of condensation tubes in the zone for the outlet of the vapor from the box, thus avoiding any obstacle when entering the condensation zone of the heater.
  • the heater 10 according to the invention shown in FIG. 3 comprises a cylindrical envelope 11.
  • a vertical inlet 12 of superheated steam At the upper part of the heater 10 is disposed a vertical inlet 12 of superheated steam.
  • This input 12 is connected to a desuperheating box 13 arranged horizontally by means of a distribution box 14 arranged horizontally.
  • the boxes 13 and 14 have the lengths substantially equal to each other and are separated by a horizontal wall 15.
  • the distribution box further comprises an upper horizontal wall 16, a vertical side wall 17 and a flat inclined side wall 18 close to the wall of the casing 11 of the heater and connecting to the horizontal lower wall 19 of the box 13 by l 'through a vertical wall 20.
  • a space is provided between the partition wall 15 and the inclined wall 18 over all their lengths to allow the entry of steam into the desuperheating box 13 from the distribution box 14.
  • These tubes 21 are supported by a series of plates 22 orthogonal to the tubes. These plates are in one piece and we form a rectangle with corners superiors cut. These plates occupy the entire cross section of the box 13 with the exception of an area in the vicinity of the walls 18 and 20. These plates serve not only to support the tubes 21, but also to guide the vapor which thus circulates in currents parallel between the plates 22.
  • the vapor leaves the box 13 in the vicinity of the wall of the cylindrical envelope 11 in an area where the heater is devoid of condensation tubes, all the condensation tubes such as 23 being arranged at a level below the level of the bottom wall 19 of box 13.
  • the steam inlet can be horizontal and the tubes vertical.
  • the distribution box may include, instead of the inclined wall 18 and the vertical wall 20, a single curved wall connecting to the walls 16 and 19 and close to the wall of the envelope 11.
