Air pollutant emissions from coal-fired power plants in ...

Coal-fired power plants generate electricity by converting thermal energy into electric energy. The thermal energy is generated by coal combustion in a boiler that heats water at 1500–1600 °C (Zhou, 2016). The water vapor provides power for the turbine. Then, the turbine rotor turns the electric generator, which produces electricity.
