Storyboard Text

  • The coal is placed on the conveyor belt.
  • It then goes inside the pulveriser where it gets ground into smaller pieces. 
  • These smaller pieces move to the furnace where they get heated up (though the hot air created in the previous processes also helps with heating.
  • This mixture then goes to the boiler where it heats water and creates steam that escape through the vents above.
  • The steam then turns/powers an engine called a turbine. The steam also condenses during this process, and turns back to water so the cycle can start again. 
  • The turbine then powers a generator, and after that the energy goes to a substation/transformer which send the electricity to transmission lines.
