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.

there is two universal type of steam turbines; Impulse and Reaction. their difference is on blades. in reaction blades both pressure and speed will decrease, and speed differential in two sides of blade will turn rotor, while in impulse blades,...

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 the reaction steam turbine?

to covert dry steam to wetsteam under high pressure.with the help of boiler


What is steam velocity in turbine?

That is how fast the steam is actually moving in the turbine. For impulse turbines it is twice as fast as the turbine blades. In reaction turbines it is the same speed as the blades. Because the blades of a turbine cannot move faster than 4500 feet per second without self destructing as it overcomes the centripetal force of the turbine wheels, the steam turbine is designed such that no turbine will exceed more than ~1150 feet per second on its tip speed. Thus the steam velocity through the turbine will be less than ~1150 fps for a reaction turbine and less than ~2300 fps for an impulse turbine, or about ~1570 mph, more than twice the speed of sound.


What are the different types of steam engines?

Depends on how you want to catigorize them ... mobile or stationary piston or turbine condensing or non-condensing and weither the power comes from the steam pressure or from the vacumm you get when you condence the steam.


How do you get power from a nuclear power plant?

The controlled nuclear reaction generates large amounts of heat. That heat boils water, which creates steam. The steam turns turbine blades, and the turbine generates electricity.


Why extraction taken from steam turbine?

Why would you not heat the steam coming out of turbine and feedback to turbine?

becouse this steam is use repetdly for the turbine


How is electrical energy produced by nuclear power?

The nuclear reaction produces heat, which is used to boil water. The steam then drives a steam turbine, producing electricity.


What does steam do to a turbine?

Steam (under pressure) comes into contact with the blades of the turbine through which it is flowing and, by the direct application of force, causes the blades to move, turning the turbine shaft. The turbine coverts the thermal energy of the steam into (rotating) mechanical energy. Surf on over to our friends at Wikipedia using the provided link and get more info. Oh, and check out the pics! Answer it depends what type of turbine one is using types of steam turbine 1 impulse turbine 2 reaction turbine in 1 st one steam is completely expanded inside nozzle and all pressure energy get converted in to kinetic energy using this impulse force turbine runs. in 2nd steam is multiple stage blades are used where high pressure superheated steam gets expanded inside the turbine in each stage and after each stage velocity of steam increases. very high temperature superheated steam is reaquired because it has very high specific volume which helps in reducing mass flow rate of steam.


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.
