What is a steam turbine?
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.
What is difference between radial flow turbine and axial flow turbine?
in a radial flow turbine the steam enters the turbine in the direction of its radius and leaves it in the direction of the axis of the shaft. in a axial flow turbine the steam enters the turbine in the direction of the axis of the shaft and leaves the turbine in the same direction.
What components are present in every nuclear power plant that generates electricity?
(Nuclear reactor) creates heat Water heated to create pressurised steam (Boiler) Pressurised steam released via turbine chamber (Steam Turbine) translating motion to turbine shaft. Turbine shaft windings rotate inside magnets to generate electricity (Generator)
High pressure steam turns the blades of?
High pressure steam hits the blades of a TURBINE and turns its shaft.
How does turbine work?
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
What is meant by axial displacement in steam turbine?
Axial displacement is the motion along the shaft of the turbine caused by the force exerted by the steam or by the thermal expansion of the shaft and casing.

What is alignment of rotor shaft in steam turbine?
steam turbine is multiple shaft euipment, to avoid the viberation of the shaft train runing, the multiple shaft need to be aligned within tolorance. usually, the rim and face run out checked is request.
What is a reaction steam turbine?
Steam turbine is when a device that has the extract thermal energy from pressurized steam. It is used to do mechanical work on a rotating output shaft. The steam turbine was invented by Sir Charles Parsons in 1884.
How does steam turbine works?
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
Where exactaly located thrust bearing in steam turbine?
Thrust bearings are mounted on turbines at or near the end of the shaft, closest to the steam chest (or inlet). This is to maintain the shaft in position with the casing of the turbine, allowing the casing and the shaft to expand evenly together toward the drive end of the turbine.
What is the working principle of steam turbine?
The Steam Turbine is the one which steam worked pressured Hot and exited then the shaft of the turbine starts to and fro motion due which energy is injected through nozzle in the receiver.
What is cold rolling of steam turbine?
When Turbine shaft temp is below 100 deg.centigrade,Then rolling of turbine carried out it is called cold rolling.
What components are present in every nuclear power plant that generates electricity?
(Nuclear reactor) creates heat Water heated to create pressurised steam (Boiler) Pressurised steam released via turbine chamber (Steam Turbine) translating motion to turbine shaft. Turbine shaft windings rotate inside magnets to generate electricity (Generator)
High pressure steam turns the blades of?
High pressure steam hits the blades of a TURBINE and turns its shaft.
What is basic principle Steam power plant?
There's a boiler which produce steam. Steam drives/turns the turbine. The turbine is connected to the alternator rotor via a shaft. Turning the rotor then generate electricity.
