Wet Compression for Two GE 7F.03 Gas TurbinesGas Turbine Wet Compression
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.
