Definitions

  • the efficiency of the steam power plant can be increased because the individual processes can be adjusted independently of each other and the temperature optimally to the respective conditions.
  • thermal oils can only be heated to temperatures of up to 400 ° C.
  • parabolic trough systems with thermal oils in particular, can be very large, so that they have high technical optimization potential in the area of the water-steam cycle due to the selected magnitude, for example by multi-stage Have condensate and feedwater pre-heating.
  • a solar tower system 20 consists of a tower 21 on which a receiver 22 is arranged, in which the heat transfer medium is conducted in a pipeline 23.
  • the solar tower mirror units 24 are arranged, each having alignable mirrors 25. The light emitted by the sun 26 is directed by the orientable mirrors onto the receiver 22 of the solar tower, whereby the heat transfer medium is heated.
  • FIG. 3 shows by way of example and schematically a possible process flow.
  • the water-steam cycle 31 consists of a feedwater pump 32 which pumps the water into the pipe 33.
  • the evaporator 34 the water is evaporated, wherein the evaporator 34 is supplied for this purpose with solar energy via a parabolic trough system 1 with thermal oil as the heat transfer medium.
  • the resulting vapor is then superheated in the superheater 35.
  • the energy required for this purpose can be generated, for example, by a parabolic trough system 1 or a solar tower 20, a molten salt being provided as the heat transfer medium.
  • the overheating is supported by a hot air generator 36, which may also be a solar tower system.
