In a power plant, the function of a cooling tower is to remove the heat absorbed in the circulating water systems via evaporation. To a large extent, its efficiency depends on the air flow entering the inlet of the tower. Turbulent air flow conditions at the air inlet reduce the cooling tower performance. This causes a limitation of power output, especially during hot summer periods.


The patented solution optimizes the cooling tower performance by creating a laminar air flow into the cooling tower, enhancing efficiency and thus increasing power output.
The concept modifies the cooling tower inlet’s upper edge and ground surface: spoilers at the upper edge and rounding of the lower edge of the inlet zone permit the smooth, less turbulent air flow needed for optimized performance.


The application of this solution does not require approval by authorities.


Reference projects resulted in a 4 to 5 MWe electric gain.


Your Benefits

  • Plant performance improvement of up to 5 MWe
  • Low investment compared to other power uprate projects
  • No operational expenditures – no recurrent maintenance required
  • Low project risks thanks to application of two step approach with go / no go decision for installation
  • On-line installation requiring no plant shutdown
  • Detection of potentially other adverse operating issues like fouling may be included with the on-site measurements
