Inlet cooling

Cooling the turbine inlet air even by a few degrees can increase power output substantially. This is because cooled air is denser, giving the turbine a higher mass-flow rate and resulting in increased turbine output and efficiency. 

The power output of any gas turbine is very sensitive to ambient temperature. Maximum power typically drops by about 0.3% to 0.9% for each degree Celsius increase in ambient  temperature (0.3% to 0.5%  for each degree Farenheit). Nominal increases in Kw output on a 90F/32° day can range from 5% to 25% of a gas turbine nameplate rating depending on the inlet cooling technology, turbine design and ambient air conditions.

Camfil engineers have extensive experience and knowledge of inlet cooling based on specific environmental and end user needs. Our scope of supply comprises:

  • Evaporative coolers
