Brief Description

Shahid Montazeri Powerplant is located at the northern Isfahan, near Shahin’shar. It is one of the biggest and most important powerplants in Iran with a capacity of 1,600 megawatts. It has 8 steam units with 200 megawatts capacity which is located on a land with an area of 220 hectares. BolandPayeh is responsible for the design & build work of 4 cooling towers of 4 power units.

Technical Specifications

The design & build of cooling systems of 4 units, using a sliding formwork system of Polikon-U type, is the first experience of such kind of concrete hyperbolic cooling tower in Iran instead of the steel ones. This experience led to stop import of the specific steel plate for the cooling towers and support the local engineering capability.

The tower height from the ground level is 118 meters and the total height considering the underground structure is 122 meters. The base diameter is 103 meters. The hyperbolic concrete shell has a circular cross-section which starts with a diameter of 90 meters and reach to its end with a diameter of 63 meters by a hyperbolic curve. The concrete shell thickness changes from 1.2 meters at its start point to 18 centimeters at the end point of the shell. The concrete shell stays on 29 X-shaped legs. The X-shaped legs rest on a ring-shaped foundation with an outside diameter of 106 meters, a width of 3.5 meters and a depth of 1.2 meters. There are four major elements in this kind of tower design; the ring foundation, the X-shaped legs, the shell and the upper ring.
