POWER-GEN 2000: Evaporative Cooling System

Developed to increase output levels and improve thermal efficiency, the TURBIdek cooling system is a low maintenance means of achieving optimal gas turbine energy production. The power output and fuel consumption of a gas turbine generator is highly dependent upon mass flow and the quality of the air drawn into the combustion chamber. This system is designed to increase the output of cooler, denser air, giving gas turbines a higher mass flow rate and pressure ratio, resulting in an increase in power output and efficiency. By cooling and densifying the air, the evaporative cooling system helps optimize the combustion process by increasing oxygen levels and decreasing the amount of nitrogen oxides.

At the same time, the air scrubbing effects of the evaporative cooling media contributes to the removal of many airborne contaminants and particulates before they enter the turbine. This effectively decreases the maintenance required on filters and other equipment, resulting in low operating costs.

During the hottest part of the day, when relative humidity tends to be at its lowest, and when energy is at peak demand, the evaporative cooling effect is greatest. According to the manufacturer, with TURBIdek, at an ambient temperature of 38°C (100°F) and 30% relative humidity, it's possible to achieve a power increase of 11-24% just by cooling the intake air. Munters will be at Power-Gen in booth #3174.
