Air Inlet Cooling Nozzles

Increase process efficiency by evaporating sprayed water into inlet air to decrease temperature and increase density

Questions? Ask an Engineer

Many facilities or processes in hot, dry areas can benefit from using spray nozzles to cool the inlet air streams. Evaporating water into the inlet air can provide critical cooling of heat sensitive areas such as electronic server rooms or animal enclosures. It can also provide significant increases in efficiency of equipment such as gas turbines or air-cooled condensers by cooling the air and increasing the relative humidity level of the inlet air streams to these units. Spray nozzles can provide an effective and economic alternative to the use of electric chillers in many applications.

Turbine inlet air cooling (TIAC) is common in dry areas that experience high temperatures either year round or seasonally to improve efficiency in power generation. During the summer, when demand for electricity is at its peak, the lower density of high temperature, dry air can reduce power generation up to 30% below rated capacity. Recapturing that lost efficiency can be achieved by increasing the air density through evaporative cooling. Use of the correct misting spray nozzles ensures complete evaporation of the droplets before contact with the turbine blades.

BETE provides air cooling misting nozzles designed for the most demanding of environments. All of our turbine inlet cooling nozzles are available with an optional safety wire hole. Our misting nozzles are designed to work at high differential pressures in order to produce small drop sizes and increase cooling efficiency. Our engineers have decades of experience in fitting custom solutions for each application. Contact us today to speak with our engineers about turbine inlet air cooling solutions.
 

Selecting an Air Inlet Cooling Nozzle: 

Important factors to consider:

  • Air temperature & humidity
  • Available quench length
  • Available / required flow rate
  • Available pressure drop (∆P) across the nozzle
    • ∆P = supply pressure at nozzle inlet - process pressure outside nozzle
  • Our experienced engineers can help determine which nozzle will perform as required with your design details.
