How does coal produce electricity step by step?

Here's how the process works.
  1. Heat is created. Before the coal is burned, it is pulverized to the fineness of talcum powder.
  2. Water turns to steam. Highly purified water, pumped through pipes inside the boiler, is turned into steam by the heat.
  3. Steam turns the turbine.
  4. Steam turns back into water.

Similarly, it is asked, how coal is used in thermal power plant?

Generally coal is used as a major fuel in mostly all the thermal power plants because it's the most abundant fossil fuel, easily available at relatively low cost. For electric power generation; lignite coal is generally used. Bituminous coal is also used sometimes depending upon the availability.

What is a coal fired power plant?

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Play Video.

How thermal electricity is generated using coal?

Steam coal, also known as thermal coal, is used in power stations to generate electricity. The hot gases and heat energy produced converts water – in tubes lining the boiler – into steam. The high pressure steam is passed into a turbine containing thousands of propeller-like blades.
