  • How Do Wind Turbines Work? | Department of Energy

    Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. Wind is a form of solar energy caused by a combination of three concurrent events:

  • Butibori Power Plant - Wikipedia

    The coal is initially about 300 mm in size. It is crushed to 20 mm and then put into a coal mill, which pulverizes it into extremely fine powder of around 70 microns. The powdered coal is then supplied to the top of the boilers via tubes and primary air (PA) fans, where it is burnt to generate heat and convert the water in the boilers to steam.
