How a Coal-fired Plant Works

  1. Coal is ground into a fine powder and then burned in a boiler to produce steam.
  2. Steam spins the turbine, turning the generator and producing electricity.
  3. The steam is cooled in a condenser with water from a nearby river or lake. The cooled steam turns into water and is returned to the boiler to be used again.
  4. The cooling water returns to the lake or river. At larger plants, the water used to condense the steam goes through cooling towers before reentering a river. This prevents environmental problems that could occur from warming the river.
