1.1. Definition. A steam turbine is a mechanical device that. extracts thermal energy from pressurized steam, and converts it into rotary motion. Main advantages of steam turbines as. propulsion plants are. high power. simple, low weight and compact propulsion.
2014 10 28 STEAM TURBINES. 2. DEFINITION A steam turbine is a prime mover in which the potential energy of the steam is transformed into kinetic energy and later in its turn is transformed into the mechanical energy of
2021 12 4 The turbine consists of a single rotor to which impulse blades are attached. The steam is fed through one or several convergent nozzles. If high velocity of steam is allowed to flow through one row of moving blades. It produces a rotor speed of about 30000 rpm which is too high for practical use. fVelocity diagram:
Because the turbine generates 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
