![]() electric power plants use steam turbines.Ĭombustion gas turbines, which are similar to jet engines, burn gaseous or liquid fuels to produce hot gases to turn the blades in the turbine. Solar thermal power plants and most geothermal power plants use steam turbines. Nuclear power reactors use nuclear fuel rods to produce steam. Most steam turbines have a boiler where fuel is burned to produce hot water and steam in a heat exchanger, and the steam powers a turbine that drives a generator. Steam turbines are used to generate most of the world’s electricity, and they accounted for about 42% of U.S. Different types of turbines include steam turbines, combustion (gas) turbines, hydroelectric turbines, and wind turbines. ![]() The generator, in turn, converts the mechanical (kinetic) energy of the rotor to electrical energy. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator. In a turbine generator, a moving fluid-water, steam, combustion gases, or air-pushes a series of blades mounted on a rotor shaft. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. Electromagnetic generators driven by kinetic (mechanical) prime movers account for nearly all U.S. This current is the electricity that moves from generators through power lines to consumers. The currents in the individual sections combine to form one large current. ![]() Turning the rotor makes an electric current flow in each section of the wire coil, and each section becomes a separate electric conductor. A basic electromagnetic generator has a series of insulated wire coils that form a stationary cylinder-called a stator-surrounding an electromagnetic shaft-called a rotor. He made the first electricity generator, called a Faraday disk, which operates on the relationship between magnetism and electricity and led to the design of the electromagnetic generators we use today.Įlectromagnetic generators use an electromagnet-a magnet produced by electricity-not a traditional magnet. He found that moving a magnet inside a coil of wire makes (induces) an electric current flow through the wire. Most electricity generation is from generators that are based on scientist Michael Faraday’s discovery in 1831. There are many different types of electricity generators. An electric generator is a device that converts a form of energy into electricity. ![]()
