What is the power generation principle of thermal power plant and what is the cooling tower used for?

Thermal power plant, the main working principle is to use the hot water generated by thermal power plant to reheat and then heat. Refers to the thermal power plant that uses the extraction or exhaust of steam turbine to provide heat for users while generating electricity. Cooling tower is a device that uses water as circulating coolant to absorb heat from the system and discharge it into the atmosphere to reduce the water temperature.

Its cooling is an evaporative cooling device, which uses the principle that water exchanges heat with air after flowing contact to generate steam, and steam volatilizes to take away heat to realize evaporative cooling, and convection and radiation heat transfer to dissipate the residual heat generated in industry or refrigeration and air conditioning to reduce the water temperature, thus ensuring the normal operation of the system. The device is usually barrel-shaped.

Extended data

The cooling tower is a comprehensive product of aerodynamics, thermodynamics, fluid science, chemistry, biochemistry, material science, static and dynamic structural mechanics, processing technology and other disciplines. Water quality is a multivariable function, and cooling is a comprehensive process of multiple factors, variables and effects.

There must be residual energy (20%-25%) in the circulating water system of the cooling tower. It will gather at a certain valve when it is running, and it will be lost in vain over time. The external turbine converts these "surplus energy" into efficient mechanical energy, thus 100% replaces the fan motor of the cooling tower to achieve the purpose of saving electricity.
