What is the result of using thermal energy in power engineering?

The use of thermal energy in power engineering is primarily associated with the conversion of heat to mechanical energy. When thermal energy is harnessed, often through the burning of fuel in a boiler, it results in the generation of steam. This steam is then directed to a turbine, where it expands and causes the turbine blades to rotate. This rotation is the mechanical energy that can be converted into electrical energy via a generator.

This principle is fundamental in various types of power plants, especially thermal power plants, where the heat energy from combustion is utilized to produce steam, thereby driving turbines. The steam’s high temperature and pressure are critical to efficiently converting energy for electrical generation, making this process a cornerstone of power engineering.
