How do you control the control oil line vibrations in steam turbine?
Rohitdpatel
If,clamp is not proper fitted in control oil line that time it may happen cause in control oil line pressure also more than main oil pump disch.

Why balancing line is providing in steam turbine?
for thrust balancing.
What is balance piston line of Turbine?
it is used balance axial thrust on turbine rotor due to admitting of high pressure steam in to turbine. it basic purpose is to save thrust bearing.
What is main steam stop valve?
Used in power generation. When steam turbine is on-line the Main Steam Stop Valve is fully open. When offline it is closed. Steam to turbine is controlled thru control valves after Main Steam Stop Valve
Why boiler drum steam pressure always different from boiler main steam line pressure?
Due to pascals law
What is stagger angle?
The angle between chord line and turbine axial direction ( also known as setting angle)
Why balancing line is providing in steam turbine?
for thrust balancing.
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.

What is a full form of prds in a boiler?
PRDS stands for Pressure Reducing & De-Superheating. The outlet steam from turbine will be used mainly for generating power and also for other industrial processes (e.g, in Textile industries for heating etc.). For industrial processes, the outlet steam from turbine will not be useful because of high temperature and very high pressure. By having a PRDS line in boiler, the temperature and pressure can be reduced by means of spraying using a control valve.
What is a Quick Control Non Return Valve?
Quick control NRV is generally a non return valve that has a special mechanism of closing quickly during emergency situations. It has a quicker response than a normal NRV. It is used in places of extreme caution where the downstream fluid should not by any chance return to the equipment concerned. For example it is used downstream a turbine bleed line to prevent high pressure steam from backing into the turbine.
Why the water that is used to cool the reactor vessel of a nuclear power plant is kept separate from the water that is heated to produce steam for the turbine generators?
Not quite sure what you are referring to. In the reactor primary circuit, there are of course the main circulating feed pumps that transfer the reactor heat output to the steam raising units (PWR) or the turbine (BWR). In the event of a loss of the main power outlet line, the plant will safely shutdown, reactor and turbine/generator together, and these feed pumps will lose their electrical supply. But there is decay heat produced from the reactor and it must be kept cool to prevent fuel damage. Therefore emergency feed pumps are provided which can be run from back up diesel generators. In the PWR there is in addition the secondary loop which takes water from the turbine condenser and passes it through the steam raising units. Both types of reactor also have the turbine condenser cooling circuit which takes water from either a lake, river, or the ocean, or from air flow cooling towers, to condense the steam at the turbine back end.
How does a fish use its lateral line?
lateral line is a line on the fish body that function to detect vibrations in water
How does coal produce electricity?
Coal makes energy in 6 sorta simple steps. 1) The coal or natural gas is first burned for mainly thermal (or heat) energy. 2) That thermal energy is used to boil water and to produce steam. 3) That steam is then forced through a high pressure tube called a steam line. 4) The steam then pushes a turbine (which is very electrical and i don't know what goes on in there) 5) That turbine then produces electrical energy. 6) The electrical energy is transported to your home and then you use it for searching the internet on how coal makes energy! (how convenient!)
What is the first line of the song for the letters BVDSBAMD?
Big Vibrations
The purpose of a bypass valve in larger-size gate valves is to?
In an application of pressure reduction, the warm up valve (bypass valve) is used to warm the steam line, within recommended time frames, before the control valve is placed into operation. A steam control valve should not be used for warm up of a steam distribution line.
What are the last 2 steps in an electrical power plant?
The last two steps are:The steam or gas spins the turbinesthe turbines then turns the electric generators producing elecricity
