The key operational difference between a natural draft cooling tower and an induced draft cooling tower is the method used to create airflow through the tower. A natural draft cooling tower relies on buoyancy, the natural convection of warm, moist air rising due to its lower density compared to the surrounding cooler air. The tower is typically a very tall, hyperbolic structure that enhances this natural airflow. The warm water from the condenser is sprayed into the tower, where it cools by evap....
