01-03-2021The mixture of pulverized coal and air is taken into the boiler and then burnt in the combustion zone. On ignition of the fuel, a large fireball is formed at the center of the boiler and a large amount of heat energy is radiated from it. The heat energy finds use to convert the water into steam at high temperature and pressure.

23-09-2021Coal-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 the water, and returned to the boiler to start the process over.
