FIELD: power industry. ^ SUBSTANCE: absorber of cylindrical parabolic concentrator of solar power with sun tracking system is arranged in cylindrical parabolic concentrator with small focus distance, the focus of which is combined with focus of cylindrical parabolic concentrator of solar power with sun tracking system. Absorber is V-shaped and consists of tubes with selective or other black coating. Rear side of concentrator with small focus distance, in which the absorber is located, is covered with effective heat insulation with heat mirror, and front side is covered throughout the length with convex glass serving as converging lens. In order to simplify the tracking of the sun altitude, absorber length has been increased in relation to length of cylindrical parabolic concentrator of solar power with sun tracking system; at that, elongation of absorber is restricted with concentrated light incidence angle on glass of 42 degrees, and optimum is 30 degrees. ^ EFFECT: obtaining maximum power absorption of concentrated solar radiation supplied from cylindrical parabolic concentrator of solar power with sun tracking system, reducing heat losses, especially during winter season, and simplifying the sun tracking system in the part of the change of the sun altitude in the daytime. ^ 2 dwg |
