6. Thermal Power Plant: "A thermal power plant is a power plant in which the prime mover is stream. Water is heated, turns into steam and spins a turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated, this is known as a Rankine cycle.
