Wet Compression option
Wet Compression (WetC) increases the power output by injecting water into the gas turbine inlet. This optional SGT5-4000F feature can be used for peak-load machines to benefit from high electricity prices
WetC enhances the turbine performance by reducing compressor inlet temperatures and increasing the mass flow throughout the turbine. Excess fog droplets evaporate in the compressor and produce an additional intercooling effect.
Chiller System option
The chiller is a heat exchanger, which cools down the compressor intake air in order to increase the gas turbine base load performance. The system can decrease the compressor inlet temperature far below the dew point of the ambience.
A chiller system can generate benefits in dry regions, where the high water consumption of other inlet air cooling options is undesirable.
Evaporative Cooling option
The system decreases compressor inlet temperature through humidification, raises relative humidity and increases the air mass flow, resulting in higher turbine output power and efficiency.
Evaporative cooling is the favorable system in dry and hot ambient.
