A thermal power plant is a type of power plant that converts the heat energy released from burning fossil fuels into electrical energy. Thermal power plants are the most common type of power plant in the world. 2. How does a thermal power plant work? Thermal power plants work using a thermodynamic process called the Rankine cycle.
A thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.
A simple steam plant works on Rankine cycle. In the first step, water is feed into a boiler at a very high pressure by BFP (boiler feed pump). This high pressurized water is heated into a boiler which converts it into high pressurized super heated steam. This high energized steam passes through steam turbine (a mechanical device which converts flow energy …
