Water injection skids are used to boost the pressure of power plant DI water supplies for injection into the compression stages of gas turbines. The purpose of these systems can be to lower NOx levels in gas turbine exhaust or to provide a power “boost”?. Systems include high-pressure centrifugal pumps, duplex filters, and various instruments to measure pressure, flow, and temperature of the water. Systems are skid mounted for easy and safe transport to the field, and are available with enclosures for noise abatement and weather protection.
Cobey has designed and manufactured water injection skids for use at power generation facilities around the United States as well as South America and Europe. Several packages have been combined with fuel injection systems, providing a single, combined package of two gas turbine utilities. This provides a more efficient package in terms of both manufacturing and field installation.
