Question

what is use of thermal power plant?

Answer 1

It produces electricity to put on the electrical grid.

Other uses:

producing power only for a private client.

Using extraction steam from a steam turbine for process heat at a plant nearby, such as a paper manufacturer.

Producing power using waste heat that occurs in processing, such as a chemical plant that produces heat from a reaction. Waste heat is sent to a waste heat boiler, producing steam that is used in a turbine generator set.

Producing electrical power from geothermal energy either using hot water injection or using a chemical that turns to a gas which is then used to turn a turbine generator set.

As a quick start back up to solar energy and or wind energy (combustion turbines) where it is the secondary means of power production.

Thermal plants can burn many different sources and types of fuel. Whatever is cheapest or plentiful. Even burning trash instead of burying trash, then producing power from the heat generated.

Answer 2

A steam/thermal power station uses heat energy generated by burning coal to produce electrical energy. This type of power station is widely used around the world. This power station uses the rankine cycle. This is the cycle of the steam produced in the boiler, then taken to the steam turbine ( prime mover ).
