Definitions

  • forced-circulation heat-transfer steam-generators comprise essentially clusters of straight vertical tubes mounted in a casing, the circulation of the heattransfer or heating fluid (consisting for example of carbon dioxide) taking place externally of the tubes and parallel to their axes in the downward direction, the fluid to be heated, consisting for example of ordinary water, circulating upwards in these tubes.
  • the heattransfer or heating fluid consisting for example of carbon dioxide
  • This pressure equalization permits of avoiding the distortion of the inner core and the creation of strains in this core as a consequence of the substantial pressure values attained in said annular space.
