General Product Information

Get more power for more flexibility

Siemens developed Flex-Power Services™ to offer you solutions for a wide range of aspects of the changed operational requirements, such as power on demand and grid services. As part of Flex-Power Services™ the Fast Wet Compression upgrade can help increase your plant’s operational flexibility.

Fast Wet Compression is a consistent further development of our successful Wet Compression upgrade. While Wet Compression was developed to optimally generate additional power, Fast Wet Compression is designed to provide additional power in a very short time. It supports the operational flexibility by using this peak power for grid code requirements. With the Fast Wet Compression System, liquid water is injected in the gas turbine inlet duct in order to cool down the gas turbine inlet air flow by evaporation. Since the water is not evaporated completely in the inlet duct, liquid water is ingested into the compressor which leads to additional inter-cooling of the compression process. This is intended to reduce the power consumption of the compressor and consequently increase the power output of the gas turbine.
