Hi sir, a small doubt in stopping the fwg, when we stop the sea water pump. I think you didn't mention it. After 50°c in evaporater side, we stop ejector p/p, so when we stop sea water p/p. Plz reply
If by pass valve will be open then jcw will be divided between by pass and and jcw inlet line so affecting evaporation of sea water in evaporator so we have to keep the by pass valve closed during operation of fwg so that all the jcw pass through inlet line to evaporate sea water and gain maximum plant efficiency....but to alter the amount of fresh water production we can throttle the by pass valve as per our requirement
1.Human Error : wait till to vacuum to build up inside FWG shell (92-95%) Technical Malfunction : During starting ensure that Ejector pump pressure is not much low ( due to which vacuum ejector won't work properly ) During starting Make Ensure There is no air leakage inside the system. Before starting there should be proper maintenance of Ejector pump otherwise ejector pump efficiency drops ( like nozzle is enlarged and wear down, vacuum ejector nozzle partially choke) and when u lay out the plant because of improper maintenance then ejector pump won't develop proper vacuum. Sometimes during starting condition there is excessive back pressure on the overboard side due to high draft of ship.(this parameter is also affect the vaccum in FWG) For more detail machining malfunction of FWG: ruclips.net/video/MnOaSGKE1QU/видео.html Thankyou!

Sir you are my Guru.Happy Guru Purnima Sir .
Excellent Sir very informative lecture
Your welcome
Thank you very, sir, for this video, nice explain
Always welcome bhai!
Thank u so much sir... Helpful lectures
Stay tuned!! For many more upcoming lectures.
Kindly advise ideal vacuum pressure in the FWG. Please.
Nice sir
Thank you sir
use of pressure relief valve in fresh water generator as we maintain in vacuum why it is needed???

Sir it is my humble request to you , to make videos on purifier (alfa laval) covering everything in conjuction mmd oral questions...please
Yes brother! Will make videos on same.Thankyou
SIR PLS MAKE VEDIO ON PURIFIER STARTING ALSO
Sir if the bypass valve is closed during the operation of producing of fresh water then how will it vapourize the sea water?
If by pass valve will be open then jcw will be divided between by pass and and jcw inlet line so affecting evaporation of sea water in evaporator so we have to keep the by pass valve closed during operation of fwg so that all the jcw pass through inlet line to evaporate sea water and gain maximum plant efficiency....but to alter the amount of fresh water production we can throttle the by pass valve as per our requirement
Bro make a video on ship manager company if company treating shore staff not good where we can complain.
Very helpful
Sir demister is made up of ?

Cause of vaccum loss during starting.....
1.Human Error : wait till to vacuum to build up inside FWG shell (92-95%)
Technical Malfunction :
During starting ensure that Ejector pump pressure is not much low ( due to which vacuum ejector won't work properly )
During starting Make Ensure There is no air leakage inside the system.
Before starting there should be proper maintenance of Ejector pump otherwise ejector pump efficiency drops ( like nozzle is enlarged and wear down, vacuum ejector nozzle partially choke) and when u lay out the plant because of improper maintenance then ejector pump won't develop proper vacuum.
