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.
Why is it necessary to open casing drains and drains on the steam line going to the turbine when a turbine is to be started?
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.
Why would you not heat the steam coming out of turbine and feedback to 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.
What is heat rate of steam turbine How to calculate heat rate of steam turbine?
manish
What is positive axial displacement of steam 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.
What is the necessary of compounding in turbines?
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.
What is pressure compounding?
Pressure compounding is a method used in steam turbines to improve efficiency by dividing the pressure drop across multiple stages. This involves passing steam through a series of turbine stages, with each stage operating at a different pressure level. By reducing the pressure drop across each stage, pressure compounding helps to extract more energy from the steam and increase the overall turbine efficiency.

Why extraction taken from steam turbine?
Why extractions are taken out from steam turbine.

What are the preventive maintenance of steam turbine?
The preventive maintenance of steam turbine mainly entails frequent servicing of the parts. This will ensure a smooth performance of the steam turbine.
What is heat rate of steam turbine How to calculate heat rate of steam turbine?
manish
What type of cycle used in steam turbine?
Rankine cycle is used in steam turbine
What is dearater in power plant?
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.
Why you are maintain the vacuum in steam turbine explain me briefly?
why we are maintain vacuum in steam turbine at steam outlet or exhaust side
