sir, make a videos on unit lit-up and shut down. It will help us
@@shraddhadas6748 ok
Sir,according to picture provided by you flue gas flows through the tube & air around it.
@@artistyacts not tube it is regenerative type APH
Sir PA fan stalling pe ek video banaiye please
Ok
SIR,DURING OPENING TIME WHY ARE WE EVEN GENERATING TRIP OIL PR. ON THE UPPER POSITION THEN DRAINING IT,INSTEAD WE CAN STRAIGHT AWAY GENERATE THE TRIP OIL FROM THE DOWN & OPEN IT
Please watch the video clearly I have mentioned all things in this video.
Trip oil is supplied at the above of piston in order to press the two part of piston against spring between them to work as one unit .
Sir,what if press 3rd pilot v/v to reset directly(without pressing 1st v/v),will aux trip oil pr. becomes zero?
As auxiliary trip oil pr between OSRD & OSTV is zero ,if you release the 1 st valve without pressing the 3rd valve ,turbine will trip.
Ist valve should not be released until all process completed
For more details please watch the video clearly ,I have mentioned all things
No sir,i mean what if we press the 3rd v/v at first..here in our plant sir log are saying first we need to check the operation of 3rd v/v,then only we need to proceed for the entire said process of yours,else if the 3rd v/v didn't work after we press the 1st v/v then we're struck.
@@artistyacts 3rd valve is used to reset the OSRD .If you press the 3rd valve Control oil will flowto aux trip line between OSRD &OSTV.If you press the 1st valve without checking the 3rd valve ,then After testing of OSTV ,it may create problem if control oil does not flow .

Sir pls explain 3rd point in NR needs blocking, tsc on & faulty, it means we don't know the actual margin avl, but it should act when we want to cross critical speed, but if Nact>2850 that means we have already crossed it, then what is the point of blocking NR, pls explain
In speed control mode Dn/Dt plays an important role when speed less than 2850 rpm.
@@rahulsirclasses1987 exactly Sir. That means NR blocking should happen when we want to cross 2850, means Nact<2850 and TSC is faulty.
As per my experience, Graphenizer-4 oil (made with Graphene) can take the Turbine lube oil system to next level for sure. a.) It forms a micro-film coat layer of Graphene like a shield inside that controls friction, wear & tear and protects from other negative factors. b.) It Increases efficiency on metal-to-metal surfaces & other internal moving parts. c.) It reduces the Over-heat up to 60% and extends the life span. d.) It also reduces the load drastically. e.) It turns the excessive noise / sound into smooth running. For more info search in google for Graphenizer-4.

Last week in our 500MW unit due leakage in HPCF pump, unit tripped due to trip oil pressure reduced, Also afte some time both HPCF pump stopped, But the vacuum breaker valve Didn't opened as you explained in video, Also from local it's not operating due to absence of control oil, Due to which High vibration observed during coasting down, as we don't have any other option, What could be the reason for not opening of vacuum breaker. Note, (Manual open command given And SLC is oFF condition)
@@trozanhorse7532 Please check wheather Vacuum breaker valve is oil operated or air operated? And also checked is it pressure to open or pressure to close?
@@trozanhorse7532 You may also check the condition of solenoid valve
Gajab vedio sir
Thanks for watching
Sir hamari turbine inner casing temp. And outer casing temp. Difference pr trip ho rahi h .. Sir what is the reason.
It may be due to non proper soaking time . Turbine tripped on HPC/IPC top / bottom Temp defference
If temp difference increases you may open MAL 81 gland steam drain valve
Thnk u sir.
The gland sealing steam header pressure is? a) 1.03 kg/cm2 b) 250 mm wc c) 1.3 to 1.5 kg/cm2 d) 1.5 to 2.00 kg/cm2 Sir iska ans 250mmwc hoga???

Why Crh has 1 safety valve & 2 safety valve of HRH
SAFETY VALVE IN CRH line :- 1 on each side ( LEFT + RIGHT ) In HRH line :- 2 on each side ( Normal safety valve + ERV) The pr. for popping of ERV is set less than that of normal SV. Pr set for ERV :- 48 kg/ cm2 For normal SV :- 49.5 Kg/ cm2 Both valves are only for indication purpose
ERV is given on only MS and HRH line
@@rahulsirclasses1987Sir in our 150 MW plant we have one safety valve on CRH & two on HRH ,can you tell the reason for the same in your case 2 on each left & right why???
@@rahulsirclasses1987 why 2 each on HRH
@@manasdas740 In HRH two Safety valve are given .Pr set for popping of SV is less in HRH as compared to CRH .The main reason is that In case of pop up ,SV of HRH should pop first in order to avoid the RH tube leakage due to starvation

IN SADC LOGIC ,oil dampers of CD and AB elevation open when OIL GUNS are taken in service perfectly, but when OIL GUNS are withdrawal they do not close on closings of HONV or LONV . HOTV and LOTV has to closed and again open then it gets close command. This is observation in our unit 250 MW BHEL unit, please tell your opinion
It may depend on c&I logic.
SIR IN 250 MW BHEL TURBINE CONDENSER TUBES ARE MADE UP OF STAINLESS STEEL, WE HAVE VERY POOR VACUUM, DO YOU SUGGEST CHEMICAL CLEANING OF TUBES .WHAT IS YOUR EXPERIENCE
@@vibhanshu1 It seems that the vacuum improves after acid cleaning of condenser tubes .some times air pressure cleaning is also done
Plz make video abt Foxboro dcs
It is a C&I related topic ,As I am a mechanical engineer not too much about this topic.I have to study before making video on this topic .
Sir after stopping of unit after how many hours we can cut steam sealing and at what temperature of HP shaft we can stop barring gear safely. Can any process is there by which we can do force cooling of HP shaft
After tripping off the unit ,first cut out the vacuum pump and then isolate the gland steam supply when the vacuum pr reaches 0.9 mmwc absolute pr . When HP shaft temp reaches 120°C close the barring gear valve . For the force cooling procedure I have already uploaded a video .please watch
Sir please make a video of cold light up procedure of 500MW from initial charging to full load
Definitely I will make video on this topic
Very good explanation sir
Thanks

Why in post purge fan trip I'd trips when furnace pressure become positive, ideally it should run to drive out the combustibles.Also in post purge trip do ID & fd trip on both furnaces postive & negative or only in positive.Plz explain
Post purge fan trip condition 1. MFT reset 2.Purging completed ,5 min complete 3.No oil gun in service means all LONV, HONV are closed. 4.Furnace pr very high or very low 5.Air flow> 30% but less than 40%
High Furnace pr or Low furnace pr. in both conditions Boiler tripped
Very good👍
Thanks
very informative video sir.
Thanks
Very well sir
Thanks. For Any query, comment
Why auxiliary damper. 100% open on master fuel trip ,Id,fd fans off & loss odf 24 volt DC?Also does ID & FD fan off doesn't come under MFT???

Sir Video ke 31-32 minute me , X1 X2 X3 criteria to HPCV-Tm par dependent hai to fir aap Tm -Shaft se kaise MS SATURATION aur MS temperature before hpbp calculate kar rahe?

Sir, one question. I understand that recirculation pump and Fan is provided to maintain oil temperature of HPSU. Why particularly this kind of arrangement is provided and not a simple DMCW water based lub oil cooler not provided?
Fire resistant fluids ( FRF) is used in LP HPSU .It offers better fire protection than mineral oils because of the higher auto ignition temperature.Circulation fan is used only to maintain temperature around 46-50°C . A regeneration pump is used to maintain the oil properties. FRF oil , a synthetic fluid contents Tri-Xylenyl Phosphate Ester demonstrates best Fire Resistant properties . Phosphate Esters are highly hygroscopic (tendency to absorb water) in nature and the esterification process is reversible when Phosphate Esters come in contact with water. This is referred to as hydrolysis. The higher the water content and temperature, the faster the ester will break down by hydrolysis.
Circulation fans are not always in service,it will cut in at a certain temp and cut out after achieving high temp.
Thank you very much sir
Sir, one more question: In HPBP OSU, there's no need for recirculation pump. I guess maybe due to change in oil property. My question is why different type of oils used in HPBP and LPBP when the use of both will be during same time?
@@handsomehardiksinh HPBP OSU is BHEL made but LPBP HPSU is German technology

Unit syc se phele Ya bad me Trim device on hota hai? Aur kis condition me OFF?
After synchronisation when load cones to 40% trip device to be on .On means untrimmed .
Upto 40% load trim device is off .It means IP CV is opened according to load .When IPCV opened to 80% then the Trim device to be untrimmed so that IPCV to opened 100%
HP-IP trim device open means untrimming of IPCV
