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 is coal used to generate electricity in the US?

  • The coal is burned and the heat given off is used to convert water into steam, which drives a turbine. In 2012, about 39 percent of all electricity in the United States was generated by coal-fired power plants, according to the U.S. Energy Information Administration.

  • 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.

  • How does a coal heating plant work?

  • The principle is simple. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal.

  • What type of coal is used in a power plant?

  • In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.
