A chimney solar power plant has been known since recent times as a utility scale solar power
plant. This technology is applicable in desert areas where solar radiation and ambient
temperature are strong.
This study presents an experimental study on the temperature evolution of the collector and
absorber in a solar chimney under real conditions. The experiments were done at the
university of Biskra (34° 51′ 00′′ north, 5° 44′ 00′′ east), located in the north of the Algerian
Sahara. The weather in this city is subtropical desert.
The used solar chimney prototype was made at the mechanical department of Mohamed
Boudiaf University in M'sila (Algeria). This prototype is composed of a collector with a
diameter of around 79 cm in hollow Plexiglas, an absorber made of steel and the solar tower
made of PVC plastic, 1.39 high and 7.5 cm in diameter.
According to the results, the temperature in the absorber or collector increases as one gets
closer to the center. Those temperatures depend on the position.
At any position, the absorber temperature is greater than the collector temperature. A
mathematical model relating the mean absorber temperature to the mean collector temperature
was proposed.
