to make a practical design
It is an engine.A steam turbine is a heat engine that uses the expansion of steam passing through stationary nozzles and blades on a shaft to turn the shaft. The steam can move through the turbine axially (one end of shaft to the other end), radially (shaft to outer casing), or tangentially (around the outer edges of the turbine wheel). In an impulse turbine, the steam is expanded in nozzles and pushes the blades. In a reaction turbine the steam is expanded in the nozzles AND in the blades, the reaction of the expansion of the steam pushes away from the blades spinning the wheel in the process. The expansion of the steam is necessary to increase its velocity through the turbine.
To avoid slugging nozzles and blades inside the turbine with condensate on start-up; this can break these components from impact. The blades were designed to handle steam, not water.
becouse this steam is use repetdly for the turbine

axial shift of a steam turbine is the shifting of turbine rotor in the forward and backward direction due to steam thrust on blades of rotor.
compounding of turbines is necessary to make the turbines practically controllable.If compounding is not done the size of the turbine will be huge.Hence by pressure &velocity compounding the turbine becomes small in size &its velocity is also becomes controllable.

Why extractions are taken out from steam turbine.
becouse this steam is use repetdly for the turbine
The preventive maintenance of steam turbine mainly entails frequent servicing of the parts. This will ensure a smooth performance of the steam turbine.
It removes the gases present in the steam,given by heaters.dearater is necessary otherwise the gases in steam will corrode the boiler and also affect the turbine.
Rankine cycle is used in steam turbine

Steam or water, it works the reverse of a fan, where the fan pushes air down, the turbine is turned by the steam or water. there's a shaft leading from the turbine to the generator, which produces the electricity
why we are maintain vacuum in steam turbine at steam outlet or exhaust side
