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.
What are the steps in a coal fired power plant?
The basic processes are conversion of the chemical energy in coal to heat, then to mechanical energy, and finally to electrical energy. Most of the steps in a coal fired power plant are common to all other thermoelectric power plants. The use of coal as a fuel in coal power plants presents some challenges, however,…
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.
What percentage of electricity is generated from coal?
Coal-fired power plants currently fuel 37% of global electricity and figures from the IEA show that coal will still generate 22% of the world鈥檚 electricity in 2040, retaining coal鈥檚 position as the single largest source of electricity worldwide. How is coal converted to electricity?
