1.The economical generation of high temperature and pressure steam is required to reduce the pressure to utilize for various purposes. This will be done by steam turbine there by developing power to run pump etc…
2.A pump driven by turbine can be operated over a wide speed range utilizing the turbine governor system.
3.The use of steam turbine driver permits operation of the driven pump is independent of electric power or distribution system.
4.A turbine may be used as stand by drive system.
5.The steam turbine controls-governor system and over speed trip system are inherently spark proof.
6.Steam turbines are inherently self-limiting with respect to power developed. Special protective devices are not required to prevent damaging the turbine because of over load condition.
