The sequence of these activities is shown in Figure 2.1. The chemical energy
Get PriceRotating turbines attached to electrical generators produce most commercially available electricity. Turbines are driven by a fl uid, which acts as an intermediate energy carrier. The fl uids typically used are: • Steam in steam turbines – Water is boiled by nuclear fi ssion or the burning of fossil fuels (coal, natural gas, or petroleum)

Steam Turbine • A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. • Steam turbines are used for the generation of electricity in thermal power plants, such as plants using coal fuel oil or nuclear fuel. 13
Get PricePower plants need steam to generate electricity. The steam rotates a turbine that activates a generator (alternator), thus producing electricity. Conventional power plants burn fossil fuels to boil water. Geothermal power plants, instead, use steam produced from geothermal reservoirs, located at several hundred to a few thousand meters below
Get Price*/ A combined-cycle power plant uses both a gas and a steam turbine together to produce up to 50 percent more electricity from the same fuel than a traditional simple-cycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power. This is how a combined-cycle plant works to produce electricity and captures waste heat from the gas turbine to
