  • the heating surfaces are connected in the water-steam cycle of the steam turbine.
  • 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 live 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.

  • the invention is based on the consideration that in order to achieve a particularly high operational flexibility even in start-up or low-load operation, a particularly large proportion of the total available heating surfaces should be usable for evaporation purposes.
  • a superheater heating surface connected downstream of the evaporator throughflow heating surface should also be used for evaporation of the flow medium if necessary, that is to say just for start-up or light-load purposes.
  • the evaporation end point should be slidable into the superheater heating surface.
  • the transition area between the evaporator passage heating surface and the subsequent superheater heating surface should be designed such that a feed of water into the superheater heating surface is possible.
