<p>The invention relates to a solar energy collecting plant intended to prepare and store domestic and industrial hot water having a temperature of more than 70°C and to prepare steam of more than 100°C. According to the invention, the plant comprises at least five concave mirrors (1) arranged in stages on a vertical metal pipe (2) on which the solar radiation incident on the mirrors (1) is concentrated and wherethrough a working fluid, such as water or another liquid, circulates, a heat exchanger (3) with a heat transfer coil (4), some valves (5 and 6), a pump (7) and a water charging pipe (8), a valve (9) for the control of the water amount entering the heat exchanger (3), a level sensor (10) mounted at a height of 3/4 of the height of the heat exchanger (3) and intended to control the opening and closing of the valve (9) so that a quarter of the volume of the heat exchanger (3) is used as water vaporization space and steam accumulation and heating space.</p> |
