Fog System
Why inlet air cooling? Combustion turbines are mass flow engines. The output of the turbines is therefore dependent on the properties of the air flowing through the engines.
Increased turbine output and reduced heat rate
As the inlet air temperature increases, its density and therefore the mass flow through the turbine decreases. Fogging helps to restore the «lost power» and improves the heat rate of gas turbines.
Inlet cooling will increase the mass flow through the turbine, increase the pressure ratio, and reduce the work of compression. The result will be increased turbine output and reduced heat rate.
