This would be the cheapest option. You can also design the heat storage so that when the sun fails, for example, it generates electricity for a week from stored energy. In any case, it is interesting to know how long one can generate electricity from stored solar energy under economic conditions.
  • the granules have a particle diameter between 20 mm and 50 mm, so that the heat between the individual particles is predominantly transmitted by the radiation. It is conceivable that the upper layers of the heat storage mass have a relatively larger granules and the lower layers consist of granules of smaller diameter, because the heat is better transmitted to the finer granules by the air circulation. Evaporation tubes, which are or are immersed in the granules, can be ribbed on the outside. In this way, the heat is transferred by the radiation and convection from the bed to the tube ribs and to the tube wall. From the pipe inner wall, the heat is further (if provided) to the corundum balls in the pipe interior through the Heat conduction and transmitted by the radiation. Instead of the corundum balls you can use the cast steel balls.
  • the thermal power process represents a new arrangement and operating method of inherently inventive significance. Accordingly, the new cycle process is composed of four partial cycle processes. On one shaft there is a steam turbine and three turbines working with binary mixture. All four turbines together drive the shaft in rotation. In a steam turbine, the steam relaxes to 5 bar and up to a temperature which is greater than 152 0 C (saturation temperature). After expansion, the exhaust steam is led into a heat exchanger where it transfers some of its heat to a heating water circuit. The binary mixture vaporizes in turn by passing through three evaporators and vaporizing a subset in each of the three vaporizers. In the evaporators for binary mixture there are different thermodynamic states.
  • each turbine process is responsible for each cycle.
  • the heating water enters the first evaporator with the temperature of 150 0 C and leaves the last evaporator with the temperature of 55 0 C. In this way one reaches in the steam cycle a theoretical efficiency of 25% (this was a vapor pressure of 100 bar and the steam temperature is based on 500 ° C.).
  • a theoretical efficiency of 25% this was a vapor pressure of 100 bar and the steam temperature is based on 500 ° C.

Abstract

L'invention concerne une centrale solaire comprenant des collecteurs cylindro-paraboliques (1) ainsi qu'un contre-miroir parabolique (2) qui concentre une nouvelle fois les rayons du soleil et les renvoie par le sommet du collecteur cylindro-parabolique (1) sur la surface (10.1) d'une cavité où se situe l'axe de pivotement (9) pour l'orientation du collecteur cylindro-parabolique et où le rayonnement solaire est converti en chaleur, la chaleur étant directement stockée à haut niveau de température (1000 °C) dans un accumulateur de chaleur (3). Le front de température dans l'accumulateur de chaleur (3) se diffuse dans tout le volume et réchauffe la masse de l'accumulateur de chaleur (3). L'accumulateur de chaleur (3) est isolé de toutes parts. Des tubes d'évaporation armés (4) en métal résistant à la chaleur y sont coulés et sont remplis de billes en vrac (5). Lorsque l'on répand de l'eau sur les billes en vrac (5) pour extraire la chaleur, il se produit une évaporation brusque de l'eau. La vapeur d'eau est collectée dans une cuve (39) puis est conduite dans une turbine (30) en vue de sa détente. La chaleur d'échappement en provenance de la turbine (30) est transmise à un circuit de chauffage (35), cette énergie servant à faire fonctionner trois cycles (II, III, IV) à mélange binaire. Le découplage d'énergie de l'accumulateur de chaleur (3) se fait jusqu'à basse température (100 °C).
