RULES FOR PRESSURE SETTINGS OF SAFETY VALVE || HIGHEST & LOWEST PRESSURE SETTING || [हिंदी] 

Thank you so dear💕

Thanks dear

Thank you so much

Thanks 🙂

Thanks bro

Koi dikkt ni hoga, Calculation se jyada ni rkhna h bs, agr km m easy operation ho rha h to koi dikkt ni h.

And sir me Kahi me pdha hu... Correct me if iam wrong k boiler ka dangerous condition kya h k apka running plant me mssv band ho jata h and apka startup vent nhi khulta ... To us condition pe teeno k teeno safety uth Jane chaiye and jitna boiler ka capacity h utna steam vent hona chahiye like 30 ton ka boiler h to 30ton teeno safety valve vent karege....

And yeh jo calculation h yeh uske base pe IBR decide krta h ... Mjhe lgta h... Sir me galat hu to please correct kijiyega.....

Ye Correct h dear

Jo Calculation Maine video upload Kia h o IBR Calculation hi h usse Sara steam release ho jaega.

Thanks dear

Very nice job

Dear please watch my video on working and principles of safety valve I have explained this point in very detail way. Thanks

Thanks dear

Agar ap Calculation Jo bataya hu usse nikaloge jitna aayega usse Kavi v jyada pr set ni kr skte ho but plant Purana ho to usse Kam m kr skte h.

Sir jb working pressure 100bar ho ga or likha b 100bar ho ga name plate py to ye bohat kam ho jae ga is haisb sy turbine ki Trip hone ki surat me problem ban sakte ya achnk thora load boiler py kam ho ga to sefty valve uth jae ga foran

Ok

Thanks dear

Pressure settings always below design pressure, highest pressure settings not exceeding 3% of permissible working pressure, and another set at permissible working pressure or below it.

Bahut jald bna dunga dear

Thanks a lot ♥️

Sure very soon I'll provide video on this topic

Morning m video upload hoga dear

Thanks sir... Apkei video dekha kar mein bahut kuch sikha...

I have completed a separate video on this topic, very soon I'll upload

Sure dear I'll make

Jo Apne 10kg weight Ka example lie h usme weight hatane k bad us pr koi v external pressure ni rhta h, but Jo 73kg k case m apka 73kg pr ate hi uth jata aur but us pr steam Ka Pressure continue applied rhta h jisse o close ni hota h, apka 10kg weight k example se smjh lete h man lo ap 1kg kewal weight ko hataye h Yani 9kg weight h av to kya spring Pura Apne original position m retain ho jaega? Kavi ni hoga Uske upr koi load ni Hona chahie tv o Apne original position m aayega, similarly steam Ka Pressure always applied rhta h disc pr jb spring force applied steam force se jyada hoga tv usko stop krega, ni to safety valve hamesa up down krte rhega jisee chattering kahte Jo ki seat aur disc ko damage kr deta h, simple way m drum m Jo Pani inlet krwate ho uska same Pressure rkhoge to kya Pani drum m jaega?

@@PowerPlantDiscussion sir yeh baat to me smjh geya but set pressure se Kam hi ku but 73 se upar geya to safety uthega.... And wapis after venting significant amount of steam it again attains 73 kg/cm2 pressure, then my question is k ab to 73 kg h to ku nhi baith rha safety valve....

Q ki disc pr applied force aur spring force same h to kaise bnd hoga Kisi ko km Hona chahie n Yani bnd hone k lie steam applied force Kam hoga tv spring force close krega.

Superheater m steam ka pressure kam rhta h, ap dekhe honge superheater tube inlet m reducer lga rhta hai, agr pressure jyada rhega to steam ka flow kaise hoga, Q ki kv v high pressure low pressure K trf flow krta h.

Dear it's maximum working pressure which is printed on drum name plate not working pressure.

Blowdown should not more than 4% of set pressure.

Dear maximum working pressure pr hi set Kia Jata h, but Kisi v case m design Pressure of Boiler se safety Valve set Pressure Kam hi rkha Jata h.

Design Pressure and maximum working pressure m bahut difference h

@@PowerPlantDiscussion Sar is pe yek video bnaye please ham ko link beje watch krne ke liye please

Increase rate mainly 3kg/cm2 in One minute for best result.

3 to 5%

Ok

Value to manufacturer provide krte hi h dear

@@PowerPlantDiscussion bcz sir asme regulation k hisab se alg aata hbor design manufavtur k hisab se alg..

Jarur Hoga

@@PowerPlantDiscussion it means boiler drum steam ka pressure 72 se niche rahega right?

Yes dear it's under IBR rule, for boiler protection if incase of one safety valve is not popup during high pressure chances of second will pop-up which protect over pressure

@@PowerPlantDiscussion thank you sir

I have discribed in this video

Drum pr name plate m Jo maximum working pressure hota h usse set Kia jata h

Sure I'll provide

Please mention correct data if you have Available, because this described data is taken from book I think this is correct towards me.

Thanks dear
