Quick vacuum build up k lie lete h Maine achhe se explain Kia h dear, ek br without skip kie hue video delhie I think your doubt may be clear by watching carefully. Thanks
Hello sir I am prashant kumar singh, working as a Power Engineer in VEDANTA limited. I want you to make a video on PRDS. You videos are very useful for me and I am enjoying every bit of it.. keeping providing us this types of video more on turbine governing and blades.
Hogger or Ejector ko thora or details me acche se samjhaya ja sakta h new video m. Or jo diagram aap board m dikha rhe h wo practical plant ka pic m colour indicate kar k smjhaynge to bhut accha hota
Dear vacuum is created due to easily flow of steam inside turbine so proper work done achieved, if you haven't maintain vacuum it means accumulation of non condensing gas increases Which pressurised the turbine casing which ultimately damage the turbine, so never try to do bypass.
@@PowerPlantDiscussion I mean after give run command in governor turbine starts rolling ,in that time steam flow is very less ,in that time we can build up vacuum ?
During rolling time whole energy is not extracted from steam so large amount of heat exchanged in condenser so formation of non condensing gas is more during this period and if vacuum is not available means whole condensing pressure is on atmospheric pressure, so atmospheric pressure + excess non condensing gas increases very high pressure and we know the effect of excessive casing pressure.
Sir turbine efficiency m , Thermal efficiency, Mechanical efficiency and isentropic ya stage efficiency kya hota h or formula kya h details m samjhaiye
Sir Was there two air line comes from condenser, one is for hogger and another for ejector ? I can't understand it, if hogger 1st taken in line with opening of air valve which connected with condenser, after isolate the hogger how air/ non condensible gas comes from condenser. I mean say there was two different line or one line. Plz clear it. Thank you
Higher velocity ka steam jb ejector condenser m jaega to cool hone m bahut time lagega, so velocity drop krna jaruri hota h islie divergent section provide kia jata h
Sir,Please reply when our plant is running on home load,and at that time if we take main ejector in line ,then vacuum drops.why does it happen? Please reply.
At that position must check PRDS steam parameters should be healthy, gland sealing pressure should be in desired range, if all parameters in healthy conditions then vacuum should sustained by ejector.
In Ejector Condenser ,Condensate return to the Hot well ,it's okay.But sir ,In Ejector Condenser , Uncondensed Vapour where will be go, in atm or insid Ejector Condenser continue circulate hote rahega.
The whole kinetic energy of steam is not utilised during turbine rolling, so due to accumulation of these energy gradually increase of temperature and if synchronisation done then proper utilisation of kinetic energy by turbine, so this temperature start decreasing, I'll make seperate video on this topic.
Hi do you know where I can learn more about hogger especially in a multi effect desalination? it's for my engineering degree thank you so much, I have searched in Science direct but it is only a few
Why there is a procedure that...if u want to take ejector in service than first open steam valve n than air valve ..n if want to cut off than 1st close air valve than steam valve
Ab clear hua function of ejector.

Sir hydrulic test kese kiya jata hai uske liye kitna max pressure jruri hota h iske bare me btaye
1.5 time of working pressure
Why vacuum build up before turbine rolling, we can build up after rolling ( by removing interlock to rolling) , means before synchronize?
Dear vacuum is created due to easily flow of steam inside turbine so proper work done achieved, if you haven't maintain vacuum it means accumulation of non condensing gas increases Which pressurised the turbine casing which ultimately damage the turbine, so never try to do bypass.

PRDS ka bhi ak video banaye sir G
Hogger is called starting ejecter.
Ejector line my kaisye ly bataya ni accha sy trip krwana h kya
Sir mai turbine field opretar hu
Very nice dear, aise hi video k sath sath Kuch Turbine Ka book v study krte rhna bahut jald hi sare equipments ko smjh jaoge.
What will happen if non-condensable gas is not removed?
Due to accumulation of non condensing gas exhaust hood temperature increases, vacuum drop, work done by Turbine is reduced, efficiency also drop,etc
Thank u
In vaccum pulling by hogger after some time you may find that air temperature is increasing can you elaborate this phenomenon???
sir , Hogger maximum kitna vacuum creat kar sakta hai?
Sir make on video centerifuge
Dear sir hogger and ejector ka steam conjupction kitna hai.
Dear it's depends on capacity of the plant.
PRDS pe video banaiye na

Sir
Was there two air line comes from condenser, one is for hogger and another for ejector ?
I can't understand it, if hogger 1st taken in line with opening of air valve which connected with condenser, after isolate the hogger how air/ non condensible gas comes from condenser.
I mean say there was two different line or one line.
Plz clear it.
Thank you

Hey can you explain the diffrence in inter and after condensor of ejector?
Hogger ko low steam temperature (110 degree centigrade) par line me lene se kya losses hai please tell me Sir
Why we open steam line first...what happen if we open air line first....air line kholke steam line kholne pe vacuum creat karega ki nahi for hogger
Bhai ek doubt he condenser se hi ejector me ata he air but aap fir se ek condenser ka baat bol rahe hen us me doubt he
Halo sir gm
Sir kya apne boiler cbd Or ibd pr video bnai h kya
Still I haven't make
Will u try
Dono ejector ek sath service me rhete h kya..??
Hogger main diversion nozzle ki kya need h?,hamara purpose h steam ki velocity badana jo ki conversion nozzle se bad raha h
Higher velocity ka steam jb ejector condenser m jaega to cool hone m bahut time lagega, so velocity drop krna jaruri hota h islie divergent section provide kia jata h
Sir,Please reply when our plant is running on home load,and at that time if we take main ejector in line ,then vacuum drops.why does it happen? Please reply.
At that position must check PRDS steam parameters should be healthy, gland sealing pressure should be in desired range, if all parameters in healthy conditions then vacuum should sustained by ejector.
Condensete water circulated by CEP sucked by hotwell so water quality is demineralised
@@PowerPlantDiscussion Sir,by mistake I wrote quality instead of quantity.I have to know how much quantity?
I have made a video for Calculation on heat exchanger this video may helps to Calculate exact value as you asked, please wait for the video
@@PowerPlantDiscussion Thanks sir.
Sir,
Have you made any vedio on VAM chiller. If have plz share the link
In Ejector Condenser ,Condensate return to the Hot well ,it's okay.But sir ,In Ejector Condenser , Uncondensed Vapour where will be go, in atm or insid Ejector Condenser continue circulate hote rahega.
Vent provide kia jata h ejector condenser me ohi se nikal jata h
Rota meter se non condensable gases atmosphere me release hoti rehti hai
During rolling of turbine why exhaust hood temp increase
The whole kinetic energy of steam is not utilised during turbine rolling, so due to accumulation of these energy gradually increase of temperature and if synchronisation done then proper utilisation of kinetic energy by turbine, so this temperature start decreasing, I'll make seperate video on this topic.
Sir non condence gas ke sath me steam kyo nhi niklti condenser se
Q ki O condense ho jata h, jo condense ni hota h ohi top part m rhta h, but kuch amount m steam v jata h aisa ni ki kewal non-condense hi jaega
The Gland steam line is taken from hp steam header so how does its pressure is reduced
Gland steam is taken from prds line
@@PowerPlantDiscussion In my plant it is taken from HP steam header
Hi do you know where I can learn more about hogger especially in a multi effect desalination? it's for my engineering degree
thank you so much, I have searched in Science direct but it is only a few
Sir how to condense non condensable gas??
Non Condansable means these gas can't condense so it may vent through ejector condenser vent.
Why there is a procedure that...if u want to take ejector in service than first open steam valve n than air valve ..n if want to cut off than 1st close air valve than steam valve
Air line sir har jagha nahi hoti h waha kya kare
Sir steam. Ka temperature kita rehta hai
Dear it's depend on design it may be 480°C, 500°C, 540°C etc
Ejector sir kon sa principal per kaam kerta hai
Venture effect
Bernauli principal per kaam kerta hai
Starting me hogger hi ku lete h sir ejector ku ni lete?
