An ideal steam turbine is considered an isentropic process, or constant entropy process, where the entropy of the steam entering the turbine is equal to the entropy of the steam leaving the turbine. However, no steam turbine is truly isentropic and typical isentropic efficiencies range from 20% to 9

A steam turbine is a machine that extracts heat energy from pressurized steam and uses it to perform mechanical work on a rotating output shaft. Its modern representation was invented by Charles Parsons in 1884. [1][2] The manufacture of modern steam turbines involves advanced metalworking, using te

A steam turbine generator​ is a generator driven by a steam turbine. The superheated steam generated by the boiler enters the steam turbine and expands to do work, which makes the blades rotate to drive the generator to generate electricity.
