Turbines are important machines in our nation’s fleet of fossil-fueled power plants, extracting energy from domestic resources and converting it into the electricity we depend on. Turbines can also be key players in conserving resources because they can provide clean energy by using less fuel and generating fewer emissions. In a coal-fueled power plant, fuel is combusted in a large furnace to release heat energy. That energy is then used to heat a boiler that turns water into steam. The steam drives the plant’s turbine, which converts the heat energy into kinetic energy. Inside the turbine, steam flows past the turbine blades causing them to turn, like a windmill or pinwheel, except that turbines are much more sophisticated with hundreds of tightly packed blades. Steam exits the turbine and is cooled and condensed through a heat exchanger so the water can be pumped back for reuse. An axle connects the turbine to a generator that spins around with the turbine. The generator uses the kinetic energy from the turbine to make electricity, which travels out of the plant and eventually powers our businesses, homes, appliances, and more.
