How do we generate electricity from coal?

How do we generate electricity from coal? 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.

Why do we use coal to generate electricity? Coal also provides a stable source of energy (no Arab oil embargoes, no sudden scarcity like you experience with natural gas) and there is a very plentiful supply both in the U.S. and in other foreign countries. Coal is nothing more than ancient wood which has been under pressure for millions of years.

Why is coal the best energy source? Coal is a stable, secure energy source

Coal also has the unique advantage of being able to be stored on-site, providing weeks or even months of fuel supply at the power plant. This important characteristic contributes to grid reliability, resiliency and reduces fuel supply bottlenecks.

What are the 10 uses of coal?

  • Electricity Generation. Power generation is the primary use for coal worldwide.
  • Metal Production. Metallurgical (coking) coal is a key ingredient in steelmaking.
  • Cement Production. Coal is used as a key energy source in cement production.
  • Gasification and Liquefaction.
  • Chemical Production.
  • Other Industries.

How do we generate electricity from coal? – Additional Questions

Why is using coal as a source for generating electricity harmful to the environment?

Environmental impacts associated with using coal as an energy source are particulate emission, ground level ozone, smog and acid rain. Coal and fuel oil combustion emit fly ash particles into the atmosphere, which contribute to air pollution problems.

Do we still use coal for electricity?
