ABSTRACT:
A solar energy plant comprises a solar energy boiler having pre-heating, evaporation, and superheating stages, and a control system for maintaining constant the temperature and the volume of the superheated steam at the boiler outlet upon variations in the incident solary energy. The flow of water entering the boiler is divided into a main flow, passing through the preheating, evaporation and superheating stages, and a secondary water flow. A first part of the secondary water flow is injected directly into the evaporation stage and a second part of the secondary water flow is injected directly into the superheating stage. The control system includes valve means for varying the rate of flow of the main water flow, and the first and second parts of the secondary water flow such as to maintain constant the temperature of the output superheated steam.
