A Steam Turbine is a mechanical device that extracts thermal energy from pressurized steam, and converts it into rotary motion. Its modern manifestation was invented by Sir Charles Parsons in 1884. It has almost completely replaced the reciprocating piston steam engine primarily because of its greater thermal efficiency and higher power-to-weight ratio.

I.IntroductionSteam Turbine DiagramA Steam Turbine is a mechanical device that extracts thermal energy from pressurized steam,and converts it into rotary motion. Its modern manifestation was invented by Sir CharlesParsons in 1884.1It has almost completely replaced the reciprocating piston steam engine primarily because of itsgreater thermal efficiency and higher power-to-weight ratio. Because the turbinegenerates rotary motion, it is particularly suited to be used to drive an electrical generator about 80% of all electricity generation in the world is by use of steam turbines. The steamturbine is a form of heat engine that derives much of its improvement in thermodynamicefficiency through the use of multiple stages in the expansion of the steam, which results in acloser approach to the ideal reversible process.History of Steam TurbineThe first device that may be classified as a reaction steam turbine was little more than a toy,the classic Aeolipile, described in the 1st century by Greek mathematician Hero ofAlexandria in Roman, Egypt. More than a thousand years later, in 1543, Spanish naval officerBlasco de Garay used a primitive steam machine to move a ship in the port of Barcelona. [5] In1551, Taqi al-Din in Ottoman Egypt described a steam turbine with the practical application ofrotating a spit. Steam turbines were also described by the Italian Giovanni Branca (1629)and John Wilkins in England (1648). The devices described by al-Din and Wilkins ar
