how is coal used to generate electricity

Methods of Generating Electricity ScienceStruck

After undergoing heating and combustion, the water boils, and the resultant steam is used to drive the turbines to generate electricity. An alternate method is by using coal water slurry (CWS) fuel, which helps improve the efficiency of power generation. Out of the total electricity generated on our planet, around 40% is derived by heating coal.

Coal Power eskom.co.za

Producing electricity from coal starts when the coal is pulverised in huge mills into a fine powder before it is blown into huge kettles, called boilers. Due to the heat in the boiler, the coal particles combust and burn to generate heat to turn water into steam. The steam from the boilers is used to turn the blades of a giant fan or propeller

Electricity from Coal

Coal, like other fossil fuel supplies, takes millions of years to create, but releases its stored energy within only a few moments when burned to generate electricity. Because coal is a finite resource, and cannot be replenished once it is extracted and burned, it cannot be considered a renewable resource.
