A turbine extracts some of the energy from a moving fluid or gas and turns it into rotational motion. In a power plant, the rotational motion drives a generator, and the generator produces electricity.
If the turbine is in a hydroelectric plant, the moving fluid is river water pulled towards lower elevations by gravity. If the turbine is in a coal-fired plant, the fluid is high-pressure steam escaping from a boiler heated by the coal. Generating electricity by wind also uses turbines (they look a lot different, though!) to change the motion of the air into the rotation needed to drive the generator.
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.

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.
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.
when steam flow blockage occured in steam turbine due to damage of blades/nozzles than steam temperature will increase so protect the turbine from high temperature this protection is introduced.
Usually boilers provide steam to power a steam turbine. The turbine could provide electricity to run any pumps in the boiler. But boilers get their energy from a heat source.
Why extractions are taken out from steam turbine.
Using waste energy in a gas fired electricity generation plant to run a steam turbine
A steam plant is any where from 33% to 48% efficient. With a steam plant you use steam to run an electirc generator. Water is heated creating steam. Which is sent through the steam turbine.
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.
The preventive maintenance of steam turbine mainly entails frequent servicing of the parts. This will ensure a smooth performance of the steam turbine.

Rankine cycle is used in steam turbine
why we are maintain vacuum in steam turbine at steam outlet or exhaust side
It will be unbalanced and unable to run without heavy vibration as a result.
Steam turbine nozzle clearance is the total energy content available in steam. This is through a valve.
-- steam turbine -- hydroelectric turbine -- wind turbine -- hand-crank generator I think even the nuclear power plants do that ... they use the heat from the reactor core to boil water, then run it through a steam turbine to generate the electric power.
