Conclusion: Working Principle of Thermal Power Plants. In thermal power plants, the heat energy obtained from the combustion of solid fuel (mostly coal) is used to convert water into steam, this steam is at high pressure and temperature. The turbine shaft, which is connected to the generator, rotates the turbine blades using this steam.

It stands to reason that the less coal used per unit of electricity generated, the less CO2 is produced. One way to support the reduction of the amount of CO2 produced during this process is to improve the efficiency of the steam and gas turbines currently used in the generation process. These turbines convert the heat released (from burning ...
