Definitions

  • a system of battles or bafile plates arranged inside the upper end of the tubes of the evaporator ensures a first separation and in the vertical sub header to which the tube is connected and which will preferably be inclined slightly with respect to the vertical, there is located another separating device ensuring separation, for example, by the centrifugal force assumed by the mixture of water and steam ascending inside a helical device preferably disposed within a convergent element, the steam being separated out axially while the separated water runs down towards the lower part of the sub-header, where it regains a water return tube.
  • FIG. 3 shows diagrammatically a modified form of a detail of the outlet of a tube into the main header.
  • each of the tubes such as b, opening at the top into a sub-header at there are provided plates j inclined after the fashion of tie slats of a Venetian blind and which have between them spaces through which the steam from the mixture of water and steam flowing through the tube 1) can be separated ofi towards the top of the drawing.
  • Deflectors such as k are provided inside the subheader d approximately opposite the outlet of each tube 12 in such manner as to direct the water contained in the mixture of water and steam towards the lower part of the sub-header d.
  • the separator l, m, n which has just been described is preferably made of cast steel or other metal and inserted in the upper part of each of the sub-headers during the manufacture of the latter.
