Steam turbines.

General

Steam turbine is a prime mover in which pressure energy of the steam is transformed into mechanical energy of rotation of turbine shaft.Transformation of pressure energy of steam into mechanical work is brought about by different means.mechanical work is done by the action of kinetic and pressure energy of steam upon blades mounted on a rotating wheel.The pressure energy of steam is converted into kinetic energy and then it is converted into mechanical work.Steam turbine is supposed to be an ideal prime mover and has got a variety of uses.In large size it is used for driving electric generators in thermal power plants.In small size it is adoptable for driving electric generators in thermal power plants.In small size it is adoptable for driving centrifugal pumps,fans,compressors and auxiliary equipments in power plants.
