ELECTRICITY PRODUCTION FROM COAL : Coal is dropped into a hopper. The hopper feeds the furnace. As the coal burns, it heats a water tank creating high pressure steam. The steam is used to turn turbines, producing electricity. The steam produced during the process condenses back to water and is recycled for heating once again.
