Having been a power station operator for 36 years (recently retired) I can say that this is the most comprehensive and easily understood piece I have ever seen explaining the function of a deaerator. . Well done!
"orifice" is a well engineered, uniform design, calculated and dynamic hole... not just any hole. An orifice costs upwards of 30x or more what you can charge for a hole. Remember to bill appropriately. "Drilled 3/8'ths hole, deburred: $5.95" "Excavated a precision 9.525mm smoothed and chamfered orifice in location of best effect: $174.00 + $8 tool wear."
I think it is safe to assume that everything in these things are well engineered. A simple "hole" fits to my level of understanding much better thank bunch of jargon
The government don't want you being too smart too quick they want us to be smart enough to work but dumb enough not to ask questions about tax, poison food and inhibited freedom.
Highly appreciate your efforts....nothing like this on you tube except yours I think colleges should start to use your videos to explain students.....new era of teaching
Holy molly! Your voice and the way you explain are definitely clear, infomative and scientific. Honestly, I've had to watch at least 3, 4 videos or more to discover any engineering topic, but this video is the exception - Only this is enough! Respect and thank you!
We are now 3 hours deep into your videos, and I must say these are incredibly well explained the details in your videos are phenomenal. Subscribed with all notifications on. Keep up the great work!
Jon, I want to thank you for all your efforts. I use a number of the videos you have made as instructional aids in our apprenticeship courses for our Boilermakers and our Thermal Systems Engineers at California Boiler, Inc. Excellent resource!
Recently I've been told to do reserch on deaerstors at university But non of the web-sites I've saw gave me so much understanding of this theme as this video Thank you so much for this video and all of the effords you put in it.
Easy and to the point reflecting the deep understanding! One more thing can be added is how deaerators depend in also Henry’s law along with the Temp. Effect in solubility… thenk you again dear.
Although a little unrelated, this explains why drinking water from a kettle tastes better. The Ph is higher, so the water is less acidic. In a way the kettle "deaereted" the water, just by boiling it and thus removing the non condensable Co2 and O2
In a kettle, you also get precipitation of carbonates on the heating elements and other surfaces, which reduces Ph, so it's probably a bit more complex set of effects.
Dude, I fucking love you. I've been studying engineering books and your videos makes it much easier for me to understand. I'm going to take a stationary engineering test soon (not scheduled yet), and I'll be watching your videos.
Deaerators typically receive condensate water plus dissolved gases from the condenser, plus make up water. This make up water is more water with dissolved gases supplied to deaerator and may be from river or lake or city water supply with dissolved gases. Here in a deaerator, such dissolved gases are removed from water coming from the condenser as well as make up water (added water) are usually oxygen and carbon dioxide and the water is pre heated somewhat. The condenser itself usually receives exhaust steam from steam turbine, and converts this exhaust steam from the steam turbine to condensed water plus dissolved gases. This outlet water from deaerator becomes boiler feed water to be pumped to steam boiler by boiler feed pump (BFP).
## The process through which the dissolved gases are removed from water is called the “Deaeration Process”. The equipment, which is used in this method, is called “Deaerator“. # Why do we use deaerators?… The Deaerator (DA) tank uses steam to preheat boiler feedwater to a temp. at which dissolved O2 & CO2 will become separated from the feedwater before it is pumped to the boiler. The purpose is to protect the boiler and steam/condensate piping from corrosion that would be present when the water evaporates into steam. An additional benefit is that the number of chemicals used to treat the boiler water can be reduced. #water #watertreatment #saftey #boilers #explotion #hazard #plant #construction #construction techproces.com/deaeration-process/
Generally, the bfw nozzles in the boiler will try to diffuse the bfw into the boiler evenly so that it blends into the boiling water and avoids a thermal shock. If you do get a thermal shock, especially a localized one, the metal of your boiler isn't going to like that very much, as one bit will be more thermally expanded than its neighbor. Whether the boiler ends up damaged or just shrugs it off? Depends on the boiler design, the temperatures and pressures involved, and likely a bunch of other variables I can't think of.
Wonderful Job. Thanks a lot. I can't thank you enough for the indepth explanation provided. On a different note, I see that you have a video on water tube boiler with coal firing, which in my understanding is getting less and less due to environmental concerns. It would not take that extra effort to update the existing water tube with gas firing system including Flue recirculation systems. THANKS once again !
Glad you guys are back. I'm not sure if this kind of video is in your wheelhouse, but I haven't found a good video on how High Voltage Power Circuit Breakers work. Like the ones that are filled with Sulfur Hexafluoride and disconnect Power Plant Generators from the Grid, or the ones located in a High Voltage Switching Station. If you know how those work and can make a video, or series of videos for them, that would be outstanding. Also, I've found videos on how Power Plant Generators work, but it would be nice to hear your explanation of it. Also, if you could do a video on a Synchronous Condenser, and how it works, that would be excellent as well.
Perfect perfect perfect video. My suggestion for a video would be : the internal layout & operation of a multi stage flash unit (desalination). Thanks in advance.
@@savree-3d I'll try to find it, I didn't see it on your channel. MSF technology is very popular, but not match material is available on it generally. Thanks.
question please: how come feed water needs deaeration ? its already been treated,de-ionized and went through a degasifer to remove CO2, or even a thermal degasifer to remove both O2 and CO2
Each and every explanation of your working principles of Engineering Equipments videos are wonderful and the way you explain in the videos are easily grasping into the mind.... I fell in love watching all your engineering videos..... Thanks once again...for the lovely videos Mr John...
Nice video thank you, But i dont get how is possible the 0.5 bar steam and non-condensable gases diffuses 1 bar atmoshpere, is there some design technics in the hole.
Well done. My only comment is related to operating pressure and temperature . In an electric generation application with regenerative feed water heating, the operating pressure and corresponding saturation temperature could be between 50-100 psig depending on the plant cycle.
I'm 17 and I went for my 2nd class fireman's license last year when I was 16 and I passed. I'm looking to go for my 1st class fireman's license when I'm able to. One of my friends who passed the first class fireman's license said that the test was heavily focused on DAs, turbines , and other auxiliary equipment. Any tips on what to study for specifically?
very interesting, Thank you ! what is the estimated delta T that is gained by the water after passing through the spay tray deaerator? and what should be the inlet temperature of both condensate and make up water. thanks in advance

This is an essential video for any engineers that are just starting to work in a power industry. Good job sir!
I wish I was taught in this way in college. Excellent teaching. God bless you.

Same thought came into my mind. I studied thermal power plant engg. at National Power Training Institute.
Definitely the best tutorial I have ever watched. I like the way you introduce knowledge which is clear and detailed.
I use to work in the UK on boilers in the NHS. I wish this was available back in the 80s. Great videos. Cheers from NZ

Thank you very much for sharing. The second type with scrubber tend to create more vibration.
Operating 30 tone excavator this played!! I now have more understanding of how Venus's oceans boiling off contributed thanks 👍.
thanks for making very detail informative video it will help me a lot working as plant operating engineer thanks again
5:00 wonder if you could use a heat pump to condense the steam from the gas vent and provide a bit of heat for the deaerator/boiler
I love your explaintation

wow what a teacher he is!
If thermal shock is occured in boiler, because of bfw's temperature isn't high enough, what kind of impact towards the boiler directly?
Generally, the bfw nozzles in the boiler will try to diffuse the bfw into the boiler evenly so that it blends into the boiling water and avoids a thermal shock. If you do get a thermal shock, especially a localized one, the metal of your boiler isn't going to like that very much, as one bit will be more thermally expanded than its neighbor. Whether the boiler ends up damaged or just shrugs it off? Depends on the boiler design, the temperatures and pressures involved, and likely a bunch of other variables I can't think of.
