Why do power plants use naturally ventilated cooling towers? What is the difference from the induced draft type?
Due to the high water consumption in power plants and the significant energy required for cooling water, natural ventilation cooling towers are used to save energy. The difference from exhaust-driven systems is that it uses natural energy instead of electric power to drive the fan for exhaust, thus saving energy.
Simply put, it saves money, effort, and labor.
Natural ventilation cooling tower? I have been to many power plants, but I don’t think I’ve seen any; I’ve only seen air-cooled units, and even those are rare. In those cases, fans are used to drive air circulation. The Datang International Qingtongxia Power Plant, Baotou No. 2 Power Plant, and Huaneng Linhe Thermal Power Plant use air-cooled units.
