STEAM TURBINE

Steam turbine is a prime mover, which converts heat energy of steam into mechanical energy by rotating motion of the blade. Total energy conversion involves two types of steam expansion—expansion of steam in nozzle and expansion of steam in turbine blades. The function of steam engine and steam turbine are similar, but steam engine converts the heat energy of steam into mechanical energy by reciprocating motion of the piston whereas in steam turbine the energy conversion takes place due to rotation of turbine shaft. Steam energy is used for low power generation and efficiency is lesser than that of steam turbine.
