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 is the difference between back pressure and absolute pressure in steam turbine?
Back pressure is the small amount of vacuum that is created when the used steam condenses from the turbine back into re-usable water.
What is the difference between back pressure steam turbine and condensate steam turbine?
In a back pressure turbine all available energy from the inlet steam is NOT used to generate power; steam exhausts at a tangible pressure and is then used for, usually, heating or chemical processing. In a condensing turbine, all the inlet steam does mechanical work right down to the lowest pressureafter which it is condensed in a heat exchanger
How superheating of steam improves the efficiency of thermal power plant?
The amount of energy transferred from the steam is a function of the temperature difference between the input and output of the turbine. Also, superheating the steam ensures that there are no water molecules that can damage the turbine blades.
What is the difference between a pressurized water reactor and a boiling water reactor?
The primary difference between a pressurized water reactor (PWR) and a boiling water reactor (BWR) is that in the BWR, water is actually boiled, and the steam is used to drive a steam turbine, while in the PWR, the primary coolant is not allowed to boil, but is circulated in a closed loop to boil water in a steam generator. The BWR circulates primary coolant through the steam turbine in a closed loop. The PWR contains the primary coolant in a loop that includes the steam generator, and not the steam turbine.
Why vacuum is created in condenser on steam turbine?
Firstly, vacuum is being created in turbine exhaust and condenser rather than being required. It is created to reduce the back-pressures and to improve the turbine efficiency. Also, with vacuum the designers can design large size last stage blades of LP turbine for maximizing the turbine output.
What difference between clockwise and anticlockwise rotation of steam turbine?
1- it is amatter of preference 2- considered under gyroscopic precession
How ESV in turbine works?
The Emergency Stop Valve (ESV) in a turbine is placed between the steam engine and the turbine structure. It is designed to rapidly close and prevent steam from reaching the turbine in case of emergency.
Why prds used in power plants?
they work parallel to power generating turbines. The only difference between prds and turbine is that prds give only process steam by simply reducing the pressure of incoming steam while a turbine generates power out of that pressure reduction, and also give left out steam as process steam.
How a generator operated by boiler?
The boiler heats water into steam. The steam is pressurized and fed into a turbine which causes it to rotate. As the steam turbine rotates, the connected generator rotates and produces electricity. Make Sense??? Please 'Recommend Contributor'

Exhaustb hood spray in turbine?
It's the connection between the steam outlet of the turbine and the condenser to which it is attached.
