I am working in a fertilizer plant in UP, I've recently completed my 1 year training program. During my training period I didn't get proper knowledge about compressor, turbine, etc. Then one day I came to know about this channel, and trust me this guy taught everything about the compressor and turbine in well Picturised way. You deserve my respect, I've subscribed you and will be watching your videos for better understanding of things like NPSH, Pumps, Compressor, etc.
SIR, very nice method to explain of npsh a and npsh r. My ques is: What is Hydrastep in Boiler? What is the use of it? Can we see its video in your PPD videos??
Maximum continuous rating (MCR) is the capability of steam boiler to produce and provide the stated quantity of steam continually and easily with no all kinds of unwanted effects (overloading, slagging or overheating) upon the principal steam boiler and its components.it is doable to attain 8-10% extra steam coming from the steam boiler.
Calculate the boiler feed pump and motor size required for a boiler of capacity 90 TPH has steam drum working pressure 88 kg/cm2. The height of the drum is 35 meter from boiler feed pump Centre. And the suction water to pump is taken from Deaerator which is situated 15 meter above the pump centre. Given that, Boiler capacity: 90 TPH = 90 M3/hr Steam drum operating pressure = 88 kg/cm2 Steam drum height from pump centre = 35 meter Height of Deaerator tank from pump centre =15 meter Assumption: Boiler blow down 1% Deaerator operating level from floor: 2.5 meter Pressure drop in Boiler economizer: 2.5 kg/cm2 Pressure drop in feed water control station: 5 kg/cm2 Pressure drop in line, gate and globe valves and bends of feed water line: 5 Kg/cm2 Pump operating temperature: 110 °C Economizer out let feed water temperature: 275 °C Pump and motor efficiency: 65% and 95% respectively. Total required discharge head for pump = (Drum operating pressure + Drum height (m) + Economiser pressure drop + Control valve pressure drop + Pressure drop in line, gate and globe valves and bends) X 1.10 (Take 10-15% extra margin) = (88 kg/cm2 + 35 meter + 2.5 kg/cm2 + 5 kg/cm2 + 5 kg/cm2) X 1.1 Convert all the pressure head into gravity head in meter from formula P = Density X g X H…by taking the densities of fluids (water) at operating temperatures. P = Desnity X g X H Then, we have, Total discharge head = (1248 m + 35 m + 33 m + 52.5 m + 52.5 m) X 1.1 = 1563 meter Pump rated flow = (Boiler MCR + Blow down %) X 1.25 (Take 25-30% extra margin) = (90 + (90 X 1/100)) X 1.25 = 113.625= 115 M3/hr The Capacity of flow seems more, it is better to consider 3 pumps 2 running & 1 stand by Pls explain how he got 88kg/cm2 to 1248 m by using p= density *g*h formula

Thanks a lot ♥️
Yes bro ,same condition with me
Very important video and Very nicely explained. Thank you so much for sharing
Sandar explanation, very nice,
Thanks a lot
Kiya bat hai sir.... Bhut mjha aaya calculation kerne me... 😊😊😊...
Love you from JIPT students 😊😊😊
Bahut badiya explain sir.....
Thanks a lot dear
Best example thank u very much
Most welcome
Big fan sir
Teaching lavel is very good sir
amazing video
Thanks a lot
Excellent video sir.....huge respect...
Thank you so much dear ♥️
Your fundamental is very clear, great video.
Thanks❤
Very nice explaining sir
Excellent explanation sir🙏,Thank you very much 👍
Most welcome dear ♥️
Great sir 🙏🙏
Thanks a lot dear ♥️
Nice explain sir
Thanks a lot dear
Sir please make video on selection of centrifugal pump........
Sure dear I'll make
you deserve more likes bro
Very well explain sir and i have a doubt For what impact why orifice install at pump discharge just for velocity increase or anything else( Q=AV).
Pressure and velocity is maintained by pump by its casing and impeller construction,Orifice type of flow meter used for measuring flow of liquid.
@@PowerPlantDiscussion Thank you sir
Thank you for explanation, can you make video how to calculate NPSH liquid ring vacuum pump?
Sir thoda slow chalenge toh easily samajh payenge nhi toh ek hi video ko kai bar dekhna padege, aap bahot hi achha bta rahe ho sir but thoda sa slow 😊
Sure dear ♥️
Good sir
Thanks dear
Very nice brother....ek video power plant chemistry par bhi ho jaye
Thanks a lot ♥️
Sure I'll make
Sir ek request hai aap reciprocating compressor or diaphragm type compressor pr video bnaye start up shutdown
Sure dear ye topic pr bahut din se comment aa rha h thoda aur time dijie m jald hi provide kr dunga.
Thanks
Sir PRDS valve k upr ek video bna dena
Sure dear I'll make
Thanku sir 😊

SIR,
very nice method to explain of npsh a and npsh r.
My ques is:
What is Hydrastep in Boiler?
What is the use of it?
Can we see its video in your PPD videos??

Sir boiler MCR क्या है? Sir example बताईये boiler parameter के द्वारा!!!
Maximum continuous rating (MCR) is the capability of steam boiler to produce and provide the stated quantity of steam continually and easily with no all kinds of unwanted effects (overloading, slagging or overheating) upon the principal steam boiler and its components.it is doable to attain 8-10% extra steam coming from the steam boiler.
Agr sir Negative lift case me 3 metre ki jagah 50 metre ho to wo negative head a rha h?
Sir please make a video on what is hotwell condenser for CEP
Plz make video on travelling grate Boiler
Why in cep vacuum balancing line requred?
For removing trapped non condensing gas and providing NPSH at the suction of pump.
In vacuum balancing line suck water?
Ek pump ka PUMP CURVE CHART online se kese milega??
Sir yadi discharge ki hight nhi di to
Agr Pressure pata ho to discharge head Nikal skte h
@@PowerPlantDiscussion kese
5kg/cm2
H = P/0.1×SG
H = 5/0.1×1= 50m
@@PowerPlantDiscussion thanks sir
What is maximum height of suction lift?
We have three pump different npsh
2.23,2.91,3.69
Which one I chose
Kindly make It. MFD minimum Flow device In centerifugal pump
Sure
Calculate the boiler feed pump and motor size required for a boiler of capacity 90 TPH has steam drum working pressure 88 kg/cm2. The height of the drum is 35 meter from boiler feed pump Centre. And the suction water to pump is taken from Deaerator which is situated 15 meter above the pump centre.
Given that,
Boiler capacity: 90 TPH = 90 M3/hr
Steam drum operating pressure = 88 kg/cm2
Steam drum height from pump centre = 35 meter
Height of Deaerator tank from pump centre =15 meter
Assumption:
Boiler blow down 1%
Deaerator operating level from floor: 2.5 meter
Pressure drop in Boiler economizer: 2.5 kg/cm2
Pressure drop in feed water control station: 5 kg/cm2
Pressure drop in line, gate and globe valves and bends of feed water line: 5 Kg/cm2
Pump operating temperature: 110 °C
Economizer out let feed water temperature: 275 °C
Pump and motor efficiency: 65% and 95% respectively.
Total required discharge head for pump = (Drum operating pressure + Drum height (m) + Economiser pressure drop + Control valve pressure drop + Pressure drop in line, gate and globe valves and bends) X 1.10 (Take 10-15% extra margin)
= (88 kg/cm2 + 35 meter + 2.5 kg/cm2 + 5 kg/cm2 + 5 kg/cm2) X 1.1
Convert all the pressure head into gravity head in meter from formula P = Density X g X H…by taking the densities of fluids (water) at operating temperatures.
P = Desnity X g X H
Then, we have,
Total discharge head = (1248 m + 35 m + 33 m + 52.5 m + 52.5 m) X 1.1 = 1563 meter
Pump rated flow = (Boiler MCR + Blow down %) X 1.25 (Take 25-30% extra margin)
= (90 + (90 X 1/100)) X 1.25
= 113.625= 115 M3/hr
The Capacity of flow seems more, it is better to consider 3 pumps 2 running & 1 stand by
Pls explain how he got 88kg/cm2 to 1248 m by using p= density *g*h formula
Sir, Pls explain this formula is giving here , kg/cm2 to meter conversation
NpshR any formula
This is way for calculating.

where is more important of NPSH on basis of type of suction?
