  • One option is the direct evaporation ⁇ fung in parabolic trough collectors or Fresnel collectors.
  • a solar thermal power plant with parabolic trough collectors or Fresnel collectors and direct evaporation consists of a solar field with parabolic trough collectors or Fresnel collectors, in which the feed water is preheated, evaporated and superheated in the absorber tubes of the collectors, and from a conventional power plant part with a steam turbine, in the the thermal energy of the water vapor is converted into electrical energy.

  • the internally ribbed tubes can be manufactured on a large scale with only a small extra charge compared to a smooth tube.
  • the tube cooling is significantly improved by the internally ribbed tubes, because the inside of the tube up to high

  • the uniform cooling around the circumference of the tube minimizes the temperature differences between strong and less heated portions of the tube circumference. This leads to low secondary voltages and also to a high reliability of the evaporator.
