Turbine Inlet Air Cooling Nozzles
Cooling air at gas turbine inlets
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. Evaporating water into the air stream increases the density by both cooling the air and increasing its humidity level. Use of the correct Misting spray nozzles ensures complete evaporation of the droplets before contact with the rotors. Misting is often a more economic option compared to the use of an electric chiller.
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.
