Vietnam Electricity Gains 39.6 MW Boost
Gas Turbine Wet Compression
Vietnam Electricity installed MeeFog systems on two Siemens V94.2 gas turbines. The systems provide evaporative cooling and wet compression and produce a 19.7 MW power boost, resulting in a 39.6 MW total power boost for the plant. Wet compression consists of spraying water into the gas turbine compressor. The water evaporates inside the compressor. This inter-cooling effect reduces the work of compression, which causes an increase in power output.

Location: PhuMy 2.1 Extension, Vietnam
Hot day conditions: 38° with 27° C wet bulb
Elevation: Sea level
Max power boost per GT: 19.8 MW
Mee’s scope of work: Supply of fog pump skids, nozzle manifolds, and supervision of installation and commissioning
Fog System Design:
Evaporative cooling and 0.6% (for the airmass flow) as wet compression
