Engineering, procurement, and construction of 2 unit of Gas Turbine Inlet-Air Cooling Systems of Mahtab Zarand combined cycle power plant

With the round-the-clock efforts of knowledge based Engineering and Service Company and with the support of Kerman Power Generation Company and the support of TPPH, an increase of 40 megawatts was achieved in the Mahtab Zarand combined cycle power plant of Kerman. In order to achieve this, the gas turbine inlet air cooling system project was implemented and operated with the aim of removing production limitations and increasing power in the hot season.

By installing the Media system on the two gas units of Mehtab Zarand Zarand power plant, 40 megawatts of electricity production capacity has been increased during the peak consumption period. The use of this system increases the production of 20 megawatts per unit by reducing the temperature of the air entering the compressor.

Reducing the output power, especially in the hot season, when energy consumption reaches its maximum value, causes many problems. In order to solve this problem, different solutions are used. Cooling the air entering the gas turbine can reduce the mentioned limitations.

The very simple performance of media coolers as one of the evaporation methods has suggested their use as one of the best methods of cooling the inlet air of gas turbines in the world. Also, the media system installation project has been localized in the country by using the capabilities of Iranian knowledge-based companies and domestic experts at a much lower cost than the foreign model.

It should be mentioned that Mahtab Zarand combined cycle power plant is located on a land of 52 hectares with a capacity of 484 megawatts, 20 km from Zarand city of Kerman and in the vicinity of Ali Abad village.
