How does a coal power plant work?

Coal-fired 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. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

Are coal power plants safe?

Coal and Air Pollution Air pollution from coal-fired power plants is linked with asthma, cancer, heart and lung ailments, neurological problems, acid rain, global warming, and other severe environmental and public health impacts.

How is coal energy produced?

Coal-fired power plants burn coal to make steam and the steam turns turbines (machines for generating rotary mechanical power) to generate electricity. Many industries and businesses have their own power plants, and some use coal to generate electricity for their own use and mostly in combined heat and power plants.

Why is coal power plant good?

Coal-fired power plants provide affordable, reliable and constant power that is available on demand to meet energy consumption needs. As much of the world lacks access to modern, clean energy, coal is still essential to alleviating worldwide energy poverty.
