Best answer
In a nutshell,coal-fired electricity generation is achieved through quite a complex process:Black or brown coal is pulverised into a powder that鈥檚 burned in a boiler known as a furnace.The heat generated from this turns water fed into the power station into steam which passes through turbines at high pressure.The resulting steam helps move and spin the turbines that are connected to an electrical generator.More items…

How does a coal power plant work?
The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Coal power 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.
How is chemical energy stored in coal converted into energy?
The coal is usually pulverized and then burned in a pulverized coal-fired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators. Thus, the chemical energy stored in coal is converted successively into thermal energy, mechanical energy, and, finally, electrical energy.
How is co-coal used to generate electricity?
Coal is widely used to generate electricity via the following process: Coal, being a combustible rock, is burnt, the heat from the combustion of the coal is used to power a boiler.
How is coal formed?
If you wonder how is coal formed, the energy in coal comes from the energy stored by plants that lived hundreds of millions of years ago when the earth was partly covered with swampy forests. For millions of years, a layer of dead plants at the bottom of the swamps was covered by layers of water and dirt, trapping the energy of the dead plants.
