5 The Biggest Solar Furnace In The World

The Biggest Solar Furnace In The World

Posted on April 19, 2012 by team


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.

Longitudinal section of the concentrator and the heliostat field.

Sensors automatically control the place of each heliostat according to the Sun moving direction. The heliostats may rotate horizontally and vertically.

Size of each mirror – 50x50cm

    This is not the largest solar furnace in the world. The object in France is superior by 300kw, or more than 40%!

    Solar furnace or rusting remains of solar furnace? Looks like the second one. It look like it will soon collapse.

    700 kilowatts??
    I am sure you have your power figures wrong. Nothing that massive would put out such a tiny amount of electric power.

    I’m guessing it’s more like 700 MEGA watts, (700 MW) and even that figure might be a little on the low side.

    well they should be able to generate the one point twenty one gigawatts they need to run the flux capacitor. However getting this baby up to eighty eight miles per hour is going to be a real challenge. Better call the Doc for advise, good luck.
