Coalfired 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. Advantages of Coal Power Plant

A 'Thermal Power Station' produces Megawatts (MW), that is, MJ / sec by drawing that energy from whatever it is burning, albeit only at 80% efficiency (some Joules are lost) such that MJ becomes MJ ( x 80% = ) . Well, well, what a coincidence... 1 Coal is exactly what the TPS will burn in 1 second. *chuckle*.

Most traditional power plants make energy by burning fuel to release heat. Thus, they are called thermal (heatbased) power plants. They burn fuel with oxygen to release heat energy, which boils water and drives a steam turbine. This is majorly the one used by coal and oil plants. Natural gas uses a different process.
