A steam turbine is a device that extracts thermal energy frae pressurized steam an uses it tae dae mechanical wirk on a rotating output shaft. Its modren manifestation wis invented bi Sir Charles Parsons in 1884.[1]
Because the turbine generates rotary motion, it is parteecularly suited tae drivin an electric generator. The steam turbine is a form o heat ingine that derives much o its improvement in thermodynamic efficiency frae the uise o multiple stages in the expansion o the steam, which results in a closer approach tae the ideal reversible expansion process.
