Evaporative Coolers for Gas Turbines

Why use Turbine Air Inlet Evaporative Cooling?
Structured Media Technology

  • Low initial cost (EUR 20-30 / additional kW)
  • Increased Power Output – typically between 8-20 % (Increase in cooling of 0.5-1% /°C for gas turbines, 0.05 % /°C for steam turbines)
  • Increased thermal efficiency (reduced heat rate 0.2 % /°C)
  • Reduced NOx emissions (0.8-1.5 % /°C cooling)

Why use Evaporative Cooling?
Fogging Technology

  • Very low pressure loss
  • Short installation period
  • Can be retrofitted to almost any gas turbine
  • “Seamless” adaptation to achieve targeted cooling effect
  • Average droplet size below 15 micron

February 2009

Munters have successfully bid for 3 structured media projects, including 11x GE 7A retrofits in the US, which will replace ineffective fogging system (not build by Munters).

January 2008

Munters have received various larger orders mainly for Asia and the Middle East for Alstom and Siemens projects, in particular for V 94.2A and V94.3A, GT13E2 and GT 26 machines.

December 2007

Munters have finished the last (out of 12) fogging installations for ENEL, Italy on V94.3A. The fogging systems increase the output of the 12 units by more than 200 MW and thus also give ENEL a higher flexibility in their operations.

January 2007

Munters have received a contract for coolers for 6 large GE turbines with deliveries in 2007/ 2008.
