How Coal Power Plants Produce ElectricityThe heat from combustion of the coal boils water in the boiler to produce steam. …The steam is then piped to a turbine.The high pressure steam impinges and expands across a number of sets of blades in the turbine.The impulse and the thrust created rotates the turbine.The steam is then condensed and pumped back into the boiler to repeat the cycle.

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 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.
What are the characteristics of a coal fired power plant?
Figure 1. A coal fired power plant in England. Note the two tall smoke stacks where the combustion products go into the atmosphere and the shorter, wider cooling towers. Coal fired power plants are a type of power plant that make use of the combustion of coal in order to generate electricity.
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.
