As part of our ongoing commitment to meet the changing requirements of your operating assets, we offer the latest technology to help to enhance your operating plant capability and flexibility as part of Siemens Flex-Power ServicesTM. One of our modernization products is Wet Compression.
Wet Compression has been a reliable and proven method of injecting water into the gas turbine inlet. Wet Compression is perfectly suited for upgrading peak load machines. A power increase can help you take fuller advantage of high peak load electricity prices and therefore offers attractive financial payback options. Wet Compression is designed to increase the power output of the gas turbine by reducing compressor inlet temperatures, intercooling the air mass flow within the compressor and hence an increasing mass flow throughout the turbine.
The Wet Compression provides significant performance advantages and offers attractive financial payback options.
Wet Compression can be an effective system for recovering power loss experienced at high ambient temperature. The mutual occurrence of peak load electricity demand and high ambient temperature make Wet Compression economical and technical valuable.
Benefits can include:
These benefits can lead to the ability to produce more power in peaking and base load operation.
Wet Compression is largely independent of the ambient relative humidity. While somewhat higher performance improvement can be available in a very hot dry climate, Wet Compression can also be very effective at times of high humidity.
* Actual results may vary.
Besides a diligent original equipment manufacturer assessment of the gas turbine and the involved power plant components, the scope of this modernization includes:
Installation and commissioning of Wet Compression can require an outage from one to three weeks depending on plant and gas turbine configuration. We offer a full range of field service capabilities to help you manage your maintenance and outage schedules.
More than 45 Wet Compression systems are on various frame types in operation worldwide, * e.g.:
* As of July 2013
