Thanks to all of you for connecting me.
Nice information.
Thank you so much
Very good sir g
Thanks a lot dear
बहोत खूब समझाया धन्यवाद प्रणाम असो 🙏🙏
Cool sir
Thanks dear
Good. Thanks once more
Most welcome ♥️
Sir Boiler ka bhi topic cover kigiaree, Turbine ka topic bahut hi excellent hai. Thanks
Sure dear Very soon I'll start making video towards boiler side
Good explanation and needful..
Thanks a lot
Good
Super Super video Sir 👍👍👍
Thanks a lot dear
Good evening sir.. Well explain sir...
Thanks a lot dear
Thank a lot....for this discussion..
Most welcome ♥️
Very useful and informative video....
Thank you so much
Very nicely explained sir
Great explanation
Good information...
thanks for knowlege full videos
Most welcome🎉
Nicely explained !
Thanks a lot
Good support thanks for sharing..just one thing to comment:
On the Condenser drawing, "Raptur disc should be written "Rupture Disk"
Salam Alikoum!
Thanks for pointing this error
Good explanation......Good teaching skill also....Nice....Keep it up bro...
Thank you so much
Very informative 👍
Thank you sir for sharing your knowledge
Most welcome dear
Excellent
Very good 🙂
Very inspiring.
Very nice. 👍 well explain 👌🙏
Supar sir
Excellent🙏🙏
Boiler ka bhi topic banaeaeee
Sure dear I'll provide
Excellent brother
One of our turbines' exhaust hood temp rises and vaccum drops significantly upon going more than 70% of its rated load. I guess it needs shutdown (could be the same reason i.e. deposition on blades responsible for such behaviour).
Great video!
Sir turbine ka balacing line ke bare main video kijiye
Dear I have already explained this topic in axial Displacement of Turbine, please watch once my video on axial Displacement of Turbine
sir please make video for thermal power plant black out condition what action to be taken
Sure dear Very soon I'll make
Happy Diwali , God bless you...
Thank you so much
Happy Diwali
Sir ACC ke bare me thoda bistar se samjha dijiye plz.kaise kam karta hai . dhanyawad
Sure dear Very soon I'll make on this topic
Thnx sir
Sir,pls ek video turbine bleed per ek video banaiye
Ak no. Sr
Thanks dear
good evening sir
Thanks dear
👌
Sir steam main line drain line mee kitna class kaa valve lagta hai yeska video banaiye na..
Sure dear I'll make
ok sir steam valve trap sabka video banaiyega sir..kitna class kaa lagta hai
sir turbogenrator cooling system ki video de do plz
Steam turbine me after bearing replacement & cold start "generator front bush bearing" ka temperature ek side ka increase ho raha hai 90 degree tak aur generator ka hi dusre end par temperature 60 hai. Similarly "turbine rear bush bearing ka temperature bhi ek side ka increase ho raha hai 82 degree tak jab ki dusra temperature 55 to 60 degree tak hi ja raha hai. Please respond early.
Reason???
This is very important topic sir.Sir plz make a video on HP bypass oil system.
Sure dear I'll make
Sir kindley requested pls sir afbc boiler kaise dcs se operate kare 1 separate vedio banaye ...pls pls
Sure dear Very soon I'll make
Answer is at 7:50
Thank u sir. knowledgefull video.
Sir .can u tell why exhaust hood temperature increases during low load running ??
Exhaust temperature increase due to not proper utilisation of steam energy, because inlet temperature whole time remain same so slightly tends to increase.
Initally 3000rpm rotation ke liye less steam jate hai aur after synchronisation and high load me jayada ..phir bhi exhaust hood temp nahi badta.kyu..work done me kya hota hai
I have already explained this point in this video please watch once
Hii Sir,
Ye bataye ki hood spray na available ho to exhaust temp kaise control kare.
Plus high vacuum and low vaccum limits dependency parameters and effects on turbine, it's heat rate and efficiency.
By decreasing load means inlet steam energy decrease we can control or by increasing vacuum we can control
What are solution
टरबाइन फील्ड से संबंध क्वेश्चन आंसर का वीडियो बनाएं इंटरव्यू में टरबाइन के विषय में क्या क्या पूछा जा सकता है की जानकारी क्वेश्चन आंसर सहित वीडियो बनाएं
Sir journal bearing ka turbine me
Top bottom clearnace kitna hota h or radial ka clearance kitna hota hai journal bering ka
on which factor steam turbine exhaust hood direction is select
Increasing of exhaust hood temp does not detoriate vaccum, poor vaccum is one of the reason of increased exhaust hood temp
Very nice
Very nice
What is the function of rupture disk?
Sir kindly tell me..by increasing exhaust hood temperature...why vaccum drop in condenser..??
Because saturation temp increase with pressure
Dear as we know pressure is directly proportional to pressure that's why during increase in exhaust hood temperature absolute pressure inside the Condenser is increased. So, when we convert this absolute pressure in gauge Pressure we seen vacuum drops
Kindly suggest lower limit of exhaust hood temp & it's effects...
Exhaust hood temperature is inversely proportional to turbine efficiency so ultimately Thermal Power Plant efficiency.
Rpm revolution per min ya rotation per min
Revolution per minute
कृपया एक वीडियो इस पर भी बनाये की टरबाइन में लोड बढ़ाने पर RPM क्यों नहीं घटती या फिर बढती है. धन्यवाद🙏
Why LP turbine exhust hood temp increase when turbine shutting time?
One thing I want to understand that steam heat is utilised for rolling then exhausted to further system and turbine used to torque transmission to Alternator . so how steam accumulation in last stage if steam exhausted to acc or condenser ,I didn't understood. Please describe me , I have doubt in this .
Sir
Minimum load or maximum load CEP O/L temp and exhaust temp very 0.5 to 2.5 high temp.what are reasion.
Dear if condensate temperature is lower than exhaust temperature, it's good for Condenser, as we know here latent heat is rejected so temperature should be equal but so much difference in temperature doesn't create any problem
Respected sir
Hp demand pressure in steam turbine
Samjha dijiye plz
Here it is 110 degree centigrade for Siemens 660 supercritical turbine
Very nice it's depends on Turbine manufacturers design.
Bhai knha posted ho
Sir 4.72 MW ki turbine hai,usme bahut jldi exhaust ka temp badne lagta hai , kya karan ho skta hai
why exhaust temperature increase while condensate flow zero in running condition.?
Turbine aliment ditels
Kindly Expansion Bellow ka purpose in steam turbine
Sure
Kitna steam exhaust hota hai turbine se
Bleed steam ko subtract kr dijiye baki sara exhaust hoga
Full load me exhaust temp bdega to hood spre de skte hai kya sir
Sure dear we can use
Turbine vibration rieseon
Terminal I Matka detail
Apna sir mob number
Very informative 👍
Thank you so much
