![]() The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process.īecause the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. ![]() Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. Its modern manifestation was invented by Charles Parsons in 1884. Machine that uses steam to rotate a shaft The rotor of a modern steam turbine used in a power plantĪ steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. ![]()
