Gas Turbine Inlet Air Fogging on Two SW 501FD2 GTs
Gas Turbine Wet Compression
A Southwestern US Power Station installed MeeFog Systems on two SW 501FD2 gas turbines. Each system provides wet compression (2% of air mass flow) and produces a 22 MW power boost. The GT controls were modified so when wet compression is in operation the GT switches to a “wet-control curve.” This ensures a constant firing temperature is maintained, so the maximum wet compression power boost is obtained, and CO emissions stay within permitted limits.
Project Conditions:
- Elevation: 2842 feet above sea level
- Model: SW 501FD2 Gas Turbine
- Max Power Boost: 22 MW
- Mee’s Scope of Work: supply of fog pump skid, nozzle manifolds, and supervision of installation and
commissioning.
Fog Skid Design:
- Fogging Stages: 16
- Operating Pressure: 2,000 psi
- Fog Droplet Size: 8 microns SMD
- MeeFog™ Nozzle Count: 3,072
- Nozzle Flow Rate: 0.045 gpm per nozzle
- Max. Water Flow: 138 gpm
- Max. Power Requirement: 240 HP
