Safety valve is used in noncompressible fluid too, oil, water .
Not only for compressible as told by u

I want to know how many number use valves in thermal plants.
what the function of Boiler.

what there pressure of main steem line.
shall you make one full video with function of Valve.
what the hotline and could line pipe ?

[@jatindarji1]

Hello, Sir First of all thank you for giving Such all power plant related information.
I want to known that as par this vedio you told that we use PRV in no compressible fluide like water but water is not compressed in BFP & Also I want to know that after BFP feed water passed through HPH & in HPH FW side provide Safety valve so how we called it PRV ?

[@rameelwahid2331]

love from pakistan

[@ashishvitekar3474]

Very nice explain and informative video's keep it up.
But during hydro test of Boiler normal water is used to increase the pressure if it is non compressible then how pressure increases up to required pressure setting to testing purposes.
Please confirm my doubt.
Thank you very much

[@PowerPlantDiscussion]

After filling 100% drum, if you provide less amount of water it's directly raise the pressure, because of close container, soon I'll make a video for this topic in detail way

[@ashishvitekar3474]

Sir,
But water is non compressible then how pressure increases up to required pressure. Also explains about difference between Compressible and Non compressible fundamental.
Also in Boiler any pressure difference on Water side and steam side pressure parts.
Thank you very much for replied.

[@computercentre12345]

I want to give answer. Correct me if I M wrong
During hydro water taken in drum by boiler fill pump. And when drum fill 100 percent then water pr in drum increased and becomes boiler fill pump disch pr

Dear sir it's really informative video I have seen
But there is one point I'm confused as u said in ur video that PSV use for Compressible fluid and it release the pressure to the atmosphere but gas is a Compressible fluid it shouldn't be released in atmosphere it there is any thing can u please clear me

PRV means pressure reducing valve.
It is in line &
Safety valve is off line, in T connection, releasing pr. Not reducing pr or regulating

[@rakeshchauhan4343]

R/sir turbine grid ke sath synchronising hone pr turbine ki setpoint speed working speed se jyada kyu hoti h

[@ruturajbhusare4993]

To match the Frequency of Turbine and Grid👍

[@raktimgupta4609]

As soon as the machine is synchronised with the grid, due to Lenz Law of Electromagnetic Induction, the machine experiences an reverse torque which tends to reduce the required speed to maintain the grid frequency. And so the set point speed is slightly kept higher than working speed so that necessary processes can be executed by the turbine Governor-actuator for opening of valve for flowing of higher amount of steam/water, thereby increases the input to turbine ,to maintain the required speed and frequency.
Thank You
Please correct if the explanation is wrong.

Mov vs safty valve

[@yogeshjagtap6632]

For psv ...if reset point is 62 and WP is 65 then psv will never reset.. WP should be less than 62 . Or else valves will be hunting continue

[@shaileshbirajdar1963]

reset point protection comes in service only when the psv operates....means when pressure values crosses 70 psv will open and it will remain open till the system pressure drops to 62..once pressure drop 62 psv will shut and system again regain its original pressure 65

Prv ka matlav pressure reducing valve kahata he. Kiuki is ka kam he over pressure ko reduse karke kam karna

[@mohitking8361]

Hello sir

[@babathakur8070]

How to set prv

[@Mountaineering50]

Pr safety valve not necessarily opens 100%.
Because all ppl who r conversations w this field; know well, to release pr by qty, need not require to open in proportional extent. A crack open is sufficient to release.

[@Mountaineering50]

Prv doesn't discharge to anywhere,

[@amitpandey6326]

PRV और PCV अलग अलग है कि एक ही है
