Abstract

Three wall solar vacuum collector (1) (closed circuit) located in the focus of a non moving semi-cylindrical reflector (15) and regarding the use, connection of 5 or 6 or 7 solar collectors (1 ) in series the number of the collectors connected in series is a function of the pressure and the temperature of the steam that is produced for the steam-turbine (2), that is employed in junction with a electric-generator (23) to produce electric energy (34), using the condenser (25) of the steam-turbine (2) the steam is liquidated by circulating cold water or special oil, in closed circuit (27) this way we also obtain thermal energy (23). The liquidized steam-water is driven via a steam-trap (28) in a tank for the liquidized steam-water (19) and from there using a high pressure pump the liquidized steam-water (29) is inserted in the series of the solar collectors (1) to be vaporized again. The filling level (13) is retained employing an appropriate automation system (17) in the steam-boilers, while the water needed to replace the water (or steam) that could escape is done automatically in the steam-water tank via a water- softener (31). The silicon used for sealing (4) the edges of the glass-tube (9), that contains the iron- tube (3) as a third wall, and the vacuum (33) can withstand high temperatures of 300°C or even 400°C, while the tubes (3) are made of iron-tubes or seamless tubes or stainless steel pipes, and both the inner tube (6) and the outer tube (3) are sealed and can bear pressure of 20 bar or even 60 bar. Further more, they have a big diameter so that the focal points of the sun rays are concentrated throughout the whole day on the selective surface (32) off the outer tube (3) without moving the reflector (15). The rings of the inner tube (3) are half filled with water in order to facilitate the vaporization and the vacuum tubes(1) are interconnected via pairs of small tubes over and under each bottom (8) allowing the water circulate in the bottom (10) and allowing the steam at the top (14) to pass from tube (1) to tube (1) of each series of collectors.
