What are the factors affecting Cooling Tower Performance?
Circulating cooling water passes through condenser to cool the exhaust steam of the turbine. This water is cooled in cooling tower and again re-circulated by pumping system. This can be natural draft or induced draft or forced draft cooling tower depending on availability of land , water and infrastructures etc. But while selecting the cooling tower following factors are to be considered: 1. CW Flow 2. Wet bulb temperature 3. Hot water temperature 4. Cold water temperature 5. Air flow rate 6. Wind velocity and direction 7. Make up water quality 8. COC- cycle of concentration 9. Pumping head or frictional losses in CT ...
