Key Concepts

Steam Power Plant Cycle

Within the steam power plant cycle, water is heated to produce steam that drives turbines for electricity generation. After the steam has transferred its energy to the turbines, it is condensed back into water in the condenser. The cooling tower plays a critical role in this process by cooling the condenser’s circulating water, allowing it to absorb more heat from the steam and maintain the efficiency of the cycle.

Cooling Tower

A cooling tower is a heat rejection device used in power plants and other industrial applications to lower the temperature of water that has been used to absorb waste heat. It achieves this by utilizing evaporation, where a small portion of the water is evaporated, carrying away excess heat and thereby cooling the remaining water before it is recirculated within the system.

Evaporative Cooling

Evaporative cooling is a process where liquid water is converted into water vapor, absorbing energy from the remaining water and thus lowering its temperature. This principle is fundamental in the operation of cooling towers, where it enables the efficient removal of heat from the cooling water used in condensers.
