Definitions

  • Patent EP-B-005225 of the Applicant relates to a device of this kind, in which the channels allow the humid vapor to rise on either side of the superheaters in the vicinity of the internal surface of the shell, then to descend between two groups of superheaters to lead to the inlet of the separators in the vicinity of the plane of symmetry.
  • Such a device requires that the superheaters be divided into two groups separated by a central space allowing the descent of the wet steam. This requires giving the device a larger diameter, to the detriment of its size and its cost.
  • the object of the present invention is to provide a device for drying and overheating vapor of reduced bulk and weight than the known device, while ensuring cooling of the internal wall of the shell as effectively.
  • the device according to the invention is characterized in that its channels for the circulation of wet steam are separated from the chamber intake by a partition arranged on one side of the superheaters only, so that the humid vapor rises in the vicinity of the internal surface of the shell only on one side of the superheaters, then descends from the on the other side towards admission to separating bodies.
  • the figure shows the device in section through a plane perpendicular to its axis, in line with the pipes for the admission of wet steam and the discharge of superheated steam.
  • a distribution member 3 such as that which was the subject of patent FR-B-2442069 of the Applicant, distributes the wet steam in two lateral flows represented by the arrows 4 and 5 , and an axial flow represented by the arrow 6. From the left lateral flow, a first part penetrates into the blocks of separating members 7, formed for example by stacks of parallel corrugated sheets, on which the water droplets are deposited, then run off, before being evacuated by gutters and evacuation pipes, not shown.
  • the right lateral flow of wet steam enters the separator member blocks 8.
  • the axial flow represented by arrow 6, enters the separator member blocks 9 and 10.
  • a fraction of the wet steam does not pass directly into the separating members, but rises along the shell 1, as shown by the arrow 14, in a channel 15 disposed between the shell 1 and an internal envelope 16 delimiting the flow of steam to be superheated.
  • This fraction keeps the shell 1 at a relatively low temperature. It then descends on the other side of the internal envelope 16 by a channel 17 along the right side of the shell 1, as shown by the arrow 18. It is then directed by a partition 19 in a channel 20 towards the admission to separating bodies 21, where it gets rid of its residual moisture.
  • This dried fraction then joins the main dried vapor fraction to go to the overheating exchangers.
