The Big Solar Furnace represents a complex optical and mechanical mechanism with automated control systems. It consists of a heliostat field and a paraboloid concentrator forming the stationary flow of energy of high density in the focal zone of the concentrator. The area of the reflecting surface of the heliostat field – 3020m2, the concentrator – 1840 m2. The temperature in the focus of the concentrator rays exceeds 3000 C. It’s the biggest solar furnace in the world!
The solar furnace is located in Uzbekistan, its power is 700kW. There is the second furnace like this, it is situated in France.
The heliocomplex is not far from Tashkent. It was built in the period since 1981 to 1987. The place for its construction was carefully chosen: the complex is fully located on the rock mass and the quantity of sunny days a year is not less than 270 here.
The smaller solar furnace. It represents a mirror paraboloid about 2 m in diameter focusing sun rays in the spot 2 cm in its diameter.
The highest temperature the furnace may achieve – 2000 C. It gives interesting visual effects.
The project was realized thanks to efforts and enthusiasm of an academician Said Azimov. The trigonometrical point station and the memorial stone are 110 m above sea level.
The scientific heliocomplex includes 4 structural subdivisions: the main building, the heliostat field, the concentrator and the technological tower. The heliostat field consists of 62 heliostats placed in the chess order to avoid much shading.
Each heliostat has dimensions 7.5×6.5 m and consists of 195 flat mirror elements.
The reflecting surface of the heliostat field has an area of 3022 m2.
