Modes & Benefits of Coil-Based Inlet Air Conditioning for Gas Turbines

This paper was delivered at Power-Gen International, December 2015.

Power demand is often greatest at the extreme temperatures due to an inherent desire (or required need) to maintain a steady, comfortable condition. The additional energy required to offset extreme ambient conditions, whether running an air conditioner or a heater, creates additional power demand. Unfortunately, a combustion turbine performance is highly sensitive to ambient air conditions and thus extreme hot and cold temperatures negatively impacts a generating unit’s performance and operation. Coil-based inlet air-conditioning systems are designed and operated to counteract these challenging conditions and maintain a combustion turbine performance and reliability throughout the ambient temperature range.
