@@ayoubrahmati5728 It is not used because sealing steam contains air

@AS-wz7zz We did this in our power plant as a test and the condenser vacuum remained constant, I want to know if there are any risk

@AS-wz7zz I know, We did this test and the vacuum didn't drop, does NCG cause condenser or pump cep failure in the long run?

without water seal, oil will overflow

gvc discharge line me float trap hota he, pump ka discharge pressure gvc working per depend nahi he, pump sirf hotwell level maintain karega, aur discharge pressure design hota he piping resistance plus deaerator height

To measure the flow through a pipe we use flow meters. All we have pressure and temperature for the fluid flowing. To measure volumetric flow we use orifice. The orifice restricts the flow through a pipe and consequently there is a pressure difference accross the orifice plate. That difference is used to calculate the flow in pipe.

suction pressure or below atmospheric is termed as negative pressure. A blower rotating impeller cause fluid to move radially outward due to centrifugal force causing suction at centre.

Balancing line is open to charge after filter changeover and then kept close during operation, and 3 way valve is used to select filter in operation.

1. Lubrication 2. Cooling 3. Hydraulics 4. Tripping 5. Jacketing

To absorb fluctuations in oil pressure during operation

@@AS-wz7zz sir if pump oil pressure drop then how accumulator works???

@@devivara1162 suppose running pump stops, by the time standby pump starts accumulator helps maintaining gradual decrease in pressure such that pressure reduce slowly as compared to without accumulator. accumulator provides enough time during pump changeover to prevent sudden pressure fall.

because water has higher density than oil

It is water-oil seperator and removes solid particles in oil also

Because water has higher density than oil, the separation process works on density difference.

ejecter is used to create vacuum in condenser. when steam allowed to flow through nozzle, a low pressure zone is created, that's why nozzle is used

for flexibility and reliability

Sir what is reliability??🤔

@@devivara1162 why do we use generators, for more reliable backup in case of power outage

no difference

To increase heat drop in turbine and efficiency of system

NRV and Quick Control NRV function same allowing flow in one direction, QCNRV is pneumatic control, both used in extraction lines of Turbine.

Because we use convergent part to increase velocity and reduce pressure below atmosphere, suction developed at throat, the mixed fluid allowed in divergent part(diffuser) to discharge at relatively higher pressure

Main cooling water is equipment cooling water for critical equipment like BFP, Compressor, Dryer, Lube oil cooler, Alternator cooler Auxiliary cooling water is used for cooling mainly for equipment coolig water through PHE

to remove the air in suction line

DM is de-minaralized water, Raw water has impurities like silica, salts, carbonate, bicarbonate etc

liquid phase has more density than gas

GSC or GVC, both are same, recovers the heat and mass of gland steam for GSC/GVC hot media is gland steam and cold media is condensate(from cep) condensed gland steam transfered to hotwell And blower maintain suction pressure in shell side

@@AS-wz7zzwhat??

1 working and 1 standby blower for bigger units, 1 blower only sufficient for small units

App ka mobile number mill jaya kya sir

i used short form for demo, PG for pressure gauge, while TG is used for Turbine and temperature gauge

Thanks brother, we are in touch already here in youtube.

@@AS-wz7zz kindly share your contact number or mail id.

It's not possible for me to to share everything on youtube

@@AS-wz7zz thanks a lot

I have sent you the mail. Kindly go through it. Waiting for your valuable reply

while decreasing the temperature pump maximum head and efficiency will be improved, but increasing the temperature beyond saturation will cause cavitation, thats why net positive suction head is required for boiler feed pumps, ruclips.net/video/Q5ShZqIQqew/видео.html

i m getting ur joke bro, thanks for suggestion😄

youtube has bring everyone closer, you can see my creations here and i can see your suggestions too, so we are in virtual contact, thanks for appreciation sir

i have shown only two material for presentation, there are various steel grades used for valve body. you must go through the nameplate and marking of every different valve you see in industry and search for the term in web, you will get your answer. all data and markings of nameplate of all equipment/machine contains important information. gud luck

@@AS-wz7zz thanks for the valuable information

all valve makers(like ksb) strictly follows standards which are acknowledged globally. There are many standards for valve like, asme b16.34, api 600, api 602/603. These standards defines dimensions, material and pressure-temperature rating for valves. The final outcome is that a valve must sustain the pressure and temperature of fluid flowing. ruclips.net/video/IqThlQ861EE/видео.html

@@AS-wz7zz is it applicable for all types of valve.. ?

@@prempatil7498 yes for all, a valve must have marking of standard complying to, if you want to go deep just search for piping codes like asme b31.3, b31.1, etc

you can download these standard document from web, it contains all information

@@AS-wz7zz I will download.. and thank you so much for the help

for same reason why BFP is below Dearator ruclips.net/video/Q5ShZqIQqew/видео.html

yes, this is difficult and purely experimental, you need special instruments to find some datas, there is another method roughly you can calculate near about accurate eff. will upload in few days

@@AS-wz7zz already seen gud job sir

@AS can I ask question related to BFP

yes
