What is the selection criteria of Natural Draught Cooling
Tower and Induced Draught Cooling Tower . Where we prefer
NDCT and where IDCT.

Answer Posted / abdul

The basic criteria is WET BULB TEMPERATURE (WBT).Where WBT is low, NDCT shall be used and where WBT is high, IDCT shall be used. Moreover, NDCT is not very suitable for very dry climates with high dry bulb and low relative humidity, on the other hand IDCT is suitable for all weather conditions.
