Experimental investigation of the performance of a multi-purpose solar chimney power plant

摘要

The solar chimney power plant is considered of a clean power generation that needs to be investigated to enhance the performance by studying the effect of this type of configuration. The objective of this research is to present practical results of a solar chimney model. The study was conducted under environment condition of Iraq / Tikrit in May 2018. The dimensions of the solar chimney were the area of the square collector 36 m2, the chimney is a galvanize steel tube colored by black paint with diameter 20 cm, chimney height 6 m and opening collector periphery height from the ground 2 cm. The chimney tower surface temperature was higher than the temperature of the air inlet to the chimney tower by (6°C). The air temperature inside the chimney tower was increased by (2°C). The percentage of increasing of the air temperature inside the chimney tower was 5.4%. Therefore, the use of the galvanized steel chimney tower was enhanced the performance of the solar chimney power plant.
