Brief Description

Kazeroun Combined Cycle Powerplant was designed and constructed in three continues work phases on a land of 100 hectares in south-east of Kazeroun Province in 1990. The first phase including two 128 megawatts gas units was built by a Japanese company. The second phase which was started in 2001 including four gas units with the capacity of 159 Megawatts by cooperation of Iran and Italy became operational in 2003 and 2004.

Three steams units, the third development phase, including three cooling towers and the powerhouse (Building, Mechanical and Electrical works) with a capacity of 160 megawatts was awarded to BolandPayeh Co.

Technical Specifications

Three steam units of Kazeroun Powerplant which was executed by BolandPayeh Co. consist of three concrete Heller Type cooling towers. Each tower has a height of 126 meters from the foundation level. The total height of the tower is 130 meters including the underground structure. The concrete shell of the towers has a hyperbolic geometry. The towers stay on a group of X legs.

The cooling cross-section has a circular shape which starts with a diameter of 112 meters at the base and reaches to its end with a diameter of 61 meters by a hyperbolic curve. All of these three concrete towers have been designed and built using sliding formwork system pf Polikon-U type. The towers’ thickness changes with a thickness of 1.3 meters at the base to 18 centimeters at the top of tower.
