Wet Compression for Two GE 7F.03 Gas Turbines

A power plant in the U.S. installed MeeFog wet compression systems on two GE 7F.03 gas turbines. The systems provide wet compression downstream of existing evaporative coolers, which results in a nearly instantaneous power boost of 10 MW per GT. Wet compression consists of spraying water into the gas turbine compressor. When the water evaporates inside the compressor, the resulting inter-cooling effect reduces the work of compression, which causes an increase in power output.

Project Conditions:

Location: United States
Hot day conditions: 115° F with 65° F wet bulb
Elevation: 800 feet above sea level
Max power boost per GT: 10 MW
Mee’s scope of work: Supply of fog pump skids, nozzle manifolds, and supervision of installation and commissioning

Fog System Design:

Wet compression downstream of existing
evaporative cooler
Fogging stages: 2
Operating pressure: 2,000 psi
Fog droplet size: 8 microns
Nozzle flow rate: 0.045 gpm per nozzle
MeeFog nozzle count: 780
Max power requirement: 60 HP
