More than 60 MW extra for the grid at Wadi Al Jizzi Power Station

Munters Gas Turbine Evaporative Cooling (GTEC) minimizes power shortage by increasing turbine power output by more than 23%.

Wadi al Jizzi is a powerstation in the Sultanate of Oman, run by the state owned company WAJPCO. As a part of their business plan WAJPCO wanted to increase the power capacity in the plant to meet expected short falls in power.

Different scenarios were studied and installation of Munters evaporative air coolers at the inlets of the gas turbines for enhancement of the power output was selected. Our structured approach to temperature control is extremely cost-effective and quick and easy to implement.

The installation at Wadi al Jizzi consists of 11 evaporative coolers, of which 10 are evaporative coolers for Frame 6 gasturbines (airflow at 114 m3/s) plus 10 evaporative coolers for the aircooled generators. Another evaporative cooler was installed at a Frame 5 turbine (airflow at 100 m3/s) with an air/water chiller for the generator - driven by the water of the evaporative turbine cooler. The design conditions for the systems are 45°C/35%RH.

The experience from Wadi al Jizzi confirms that by installing Munters GTEC solutions the power station has been able to improve the total output of the grid by more than 60MW allowing a payback time of the investment of less than 3 years.

Get it right and you can increase power output, eliminating the need to invest in new or additional gas turbine power generation. Munters can design and supply complete turn-key systems and give you the cooling performance to realise your power improvements.
