Question

Explain with a diagram the step-by-step energy conversion in a thermal power plant.

Answer 1

In a thermal power plant, coal is burned to generate heat. This heat is used to convert water into high-pressure steam in a boiler. The steam rotates the turbines due to its kinetic energy. The rotating turbines generate mechanical energy, which the generator then converts into electrical energy. After passing through the turbine, the steam is cooled and condensed back into water in a condenser.

Energy conversions involved:

Thermal Energy → Kinetic Energy → Mechanical Energy → Electrical Energy
