Why Three Element method for Boiler Drum Level Control | Single Element Control |Steam & water Flow
ฝัง
- เผยแพร่เมื่อ 27 ส.ค. 2024
- The term “3-element control” refers to the number of process variables (PVs) that are measured to effect control of the boiler feedwater control valve. These measured PVs are: liquid level in the boiler drum, flow of feedwater to the boiler drum, and. flow of steam leaving the boiler drum.
Water level, steam flow and water flow, thanks for sharing
Welcome, please share with others
@@ElectricalAndautomation_guru thanks sir
Sir very important topic and easy to understand thanks sir.
Always welcome
Hello sir I’m actually confused because I want to understand more from your channel but can u speak more in English bc I don’t understand hindi
Yes, I can speak English. But if you want a video in English, You have to take our membership of higher level , then we will. arrange video in English.
Acha samjhaya ap ny 😊
Thanks
superb explanation thanks
Welcome
Good
So nice
Sir explain what are the functional block that used in dcs can you explain and how it error generated
Good Sir ..
Plz make one video of trouble shooting of Control valve with ABB positioner....
ok, thanks, please don not forget to subscribe our channel and don to forget to share with your friends in social media platforms.
" Feed forward Block " term can be misleading
It is a classic example of cascade control
But explanation was good
Thanks
Pls Sir make a video of feed forward and cadcade control system
Already made please the video list
Hindi best 👌 hai sir ji.
Very good
Please possible to explain scada system and E scada system
Thanks, and welcome, please subscribe and share
3 element circuit dig and connection input& output in controller
Ok
Kindly make a video on Sil sif sis and cause and effect in Hindi
Thanks for information sir ji
Welcome
Vibration prob ko kase lgaya jata h isme ek vedio bnao na sir
Ok
Thanks😊
Thank you too
Why we need compensate pressure and temperature and how it is done.
For the correct reading of the flow rate of steam.
Why are there bubbles formation due to less pressure inside the drum?
Hit concentration of solids inside the boiler at the low pressure.
What is the normal position of boiler feed water control valve, normally open or normally close
fail open
Nice one

please make videos on Flame scanner working and types
Ok, I will try .
Teeno transmitters ki wireing diagram or ek dusre se interlocking ki wire diagram bhi chahiye sir g....
Ke liye practical to ya nahin Dikhai Ja sakti Likhit mein jo hai iskus Banakar ki wiring aapko likhane koshish karta hai
What is the RSP & SS working

I hav a doubt but a good one,u n many said about swell n shrink of water inside boiler,n u said that due sudden steam load the water swells n thus gives high level n vice versa,my point is that the level transmitter measures the head(weight of liquid) of the level inside boiler ,if at certain constant pressure, temperature and flow if theres a sudden load pickup the costant volume of water swells but at that instant the mass remains the same so how come the level transmitter reads higher level when the mass of water remains the same n just the volume swells,in other words if i boil 1 ltr of water at 100 c by clossing the lid and suddenly opening it the water swells but the wieght or mass remains the same or may be less,that means the force applied at the bottom of the vessel will always remains the same no matter how much the water expands or swells this particular finding is true but its very contradictory to the practical of the boiler cud plz elaborate and clear this doubt of mine that hows that possible, when volume of water increases the weight of the water also increases.
Look, you understand this very correctly. Let me clear your confusion in this way. When the demand of steam suddenly increase then it will creates the drum level high but because the steam present in the drum suddenly gone at this position the water supply should decreases, as per logic but this will get rectified by the steam flow data.
Bubble size is affected by pressure, so if a boiler experiences a sudden extra demand for steam, its pressure drops.
The drop in pressure causes the steam bubbles in the boiler water to expand, and the level measurement can show an increase in level.
Here are the two factors pressure and temperature which creates the different scenario from the normal situation that you told in comments

@@ElectricalAndautomation_guru definitely Sir
Sir please make on video on coal boiler
Ok
Super

Good explanation dear
How I can simulate level control in vba excel?
Not possible
Nice
Thanks, please share with others.
Flow transmitter, LT, feed water connection in control valve
Ok
No offense bro but why do you Hindi ....most of us who need this kind of information speak English

Sir ye method aur industry Mai kaha use hota hai instead of boiler
Generally, not used anywhere because precise control like this does not require anywhere else.
Sir drum me teen transmitter kio lagate hai ?
So that agar ek jharab Ho hate to do se kam chalta rahega
Or koi region sir
PLZ KINDLY DO ONE VIDEO ON FULL DCS STRUCTURE INCLUDING ALL COMPONENTS
Ok
@@ElectricalAndautomation_guru Can you please explain the enthalpy maintaining process via three element control..
Feed forward vs feedback in your style?
Ok
Sir mass flow meter par full details me video bnao..
Or sir is video me FIC or RSP kya Hai...tq
Ok, sure.fic is flow indicator and controller
Rsp means remote set point
Assume different condition and explain
Ok
Full form of RSP you forgot to tell
Boiler control loop ka bare bataiye
Ok
@@ElectricalAndautomation_guru ⁉️
Sir mass flow meter pe detail me video banaye plz
Ok.
QUESTION: if this is in Hindi audience but why subtitle it English?
Is subtitle is coming
Please add temperature and pressure compensation also let us know about Bias
Ok, I will make a video on that.
Sir hydraulic ka video banaiye
K, I will try
Sir DCS ka graphics editing ka vedio bano na
Ok, sure.
Can u please,open the caption to translate?
I sill try
U can do it and that will help me so much for my final exam next week
Hindi video sahi hai
