Turbine Inlet Chilling
Turbine Inlet Chilling (TIC) is a straightforward solution to cool the inlet air for a gas turbine to maximize the turbine output across ambient conditions. This system can use water or forced air as a form of cooling. The addition of a Thermal Energy Storage (TES) tank to the chilling system can optimize performance during the hottest part of the day. Chilled water can be produced and stored at low power demand times and then used during high demand times to maximize the power available when most needed. Offers filter house/coil module retrofitting as well as TES tank design and integration experiences.
Water Cooled Turbines
Maximum Performance in a Modular Solution
The output of all gas turbine power plants decreases performance in high ambient conditions. In locations with available water and even in high humidity, turbine inlet chilling (TIC) is an effective way to increase the output of gas turbine-based power generation or gas turbine-driven compressors. TIC provides the maximum performance benefit with active controls to a guaranteed level of performance when compared to other gas turbine cooling solutions.
