  • the water-steam cycle usually includes several, z. B. three, pressure levels, each pressure stage may have a Verdampferloom phenomenon.
  • a continuous steam generator In contrast to a natural or forced circulation steam generator, a continuous steam generator is not subject to any pressure limitation, so that it is possible for fresh steam pressures far above the critical pressure of water (P Kri ⁇ 221 bar) - where no differentiation of the phases water and steam and thus no phase separation is possible. can be designed.
