Where I worked, the condensate system used a vacuum pump with a storage tank. That water was then pumped into the feed water tank where it was preheated to reach 150°.. we had 200 hp boilers, but we ran the boilers at about 6 pounds of pressure. With a special pilot regulator I was able to operate the building steam below atmosphere. This was very helpful in the mild seasons of spring and fall but we needed more pressure when it got colder because we had air handler’s bringing in outside air.
Awesome 👌 I have two boilers: 1- 400 HP and 500 HP with a condenser tank/ makeup water. Water treatment. But I used a ring on the feed of the boilers and at the end of the heating season when I do the blowout the water is clean.
You have a great content here, I work in a combine cicle electricity plant and we have this equipment that you guys talk about and I learn a los from you, specially the funtion of the deaerator that basically is the same but the one we have is like 10 times bigger than that and de feed water pumps are 4.16 kw with a high pressure around 150 bar of presion and intermate 120 bar pressure and other low pressure pump about around 60 bar of pression, it would be great that upload a video about a HRSG 3 steppes! Thanks!!
At my facility our DA tank gets treated directly with boiler chemical, we also have a condensate tank some 100' away. Does this tank also need boiler chemicals?
Unfortunately that isn't really a question that we are able to answer without seeing the setup. If you want, give us a call (1-800-228-8861) and we might be able to point you in the right direction. Thanks for watching!
When you are saying "remove oxygen from the water", you mean (ambient) air that's blended or mixed in with the water being fed into the system, right? If you remove the oxygen from water, you get hydrogen.
+Ahmad Zaki Abdul Karim Thank you. I thought that was the case, but don't know a great deal about the mechanics of steam, and didn't want to assume anything.
Actually, this process removes SOME dissolved GAS from the water, and not all. The dissolved gas is air. Air is mostly nitrogen and only about 21% oxygen. Gases are less soluble in water as the temperature goes up. They want to get rid of the oxygen component as much as they can, but the process is removing dissolved gas/air, not oxygen specifically. CO2 is only about 0.04% in air, but can reach higher levels of concentration due to the chemical conversion it undergoes, to form carbonic acid, which takes the CO2 out of solution and allows more CO2 gas to dissolve in. Also, "CO2" in the form of carbonic acid can leach into ground water from other sources other than air, like limestone. The small amount of dissolved CO2/carbonic acid, which makes the water slightly acidic, increases the power of the oxygen to oxidize the metal parts (rust). The steam is to heat the water up to facilitate degassing, and the spray action is to increase the surface area of contact betwen the steam and the water to make the process more efficient. And the plume visible at the top of the vent pipe is steam/air, not oxygen. It is the exhaust degas/steam mixture coming out, hitting the cooler outside air and condensing into tiny droplets that scatter light. If it were oxygen alone, as they say in the video right after calling it a steam vent pipe, it would be a cheap way to make/collect oxygen to sell, and it would burn. Hold a match to the plume. No way it ignites. It is just air and steam. The system is called a de-aerator, not a deoxygenator.
really new to the the plant operator position but these videos make been a great help please keep the great work up.
Me too, these videos really help!

Thanks for sharing. This is very helpful
Wonderful explanation!Thank you as always!
I'm learning as I'm watching your channel
Thanks for watching!

Glad we could help! Unfortunately we don't have a HRSG to talk about but if we get an opportunity to cover it we will. Thanks for watching!
Thanks,that was brilliant.im a boiler operator for Veolia.your videos are brilliant.
Appreciate this video soooo much!!
I really appreciate your videos!
Well we appreciate you watching!
Thank You for this Video
What are some reasons why DA tank is not maintaining temperature. Normally 225 F but most times its on or below 200F.
Hi, could you explain how is the procedure to heat the make up water, when de boiler is run for the fist time, and the water is cold?
thanks
Awesome video!!!!!
Great vid, gents
What is the need for a restrict plate in the vent of a DA tank
if u don't restrict the size of the orifice in the vent then u will not develop enuff steam pressure in the DA to get the temp of 220 to 230.
When a DA is install it there is no need for chemicals?
Hello Juan, we recorded a video answer to your question. You can view it here. ruclips.net/video/lgcjZ-Uerio/видео.html
You need to add chemicals.
Where is the building show?
Thanks. Where does an economizer fit in?
An economizer uses boiler combustion gas to preheat feedwater
At my facility our DA tank gets treated directly with boiler chemical, we also have a condensate tank some 100' away. Does this tank also need boiler chemicals?

After condensation steam becomes water and then sent through ceps to deaerator ......then how come steam comes again into the deaerator to heat water
Good video. Do you deal with evaporators as well?
We do. If you need some help or have questions the best bet would be to give us a call! 502.968.2211 Hope that helps and thanks for the comment
Wow, I don't have any deaerator in the small steam generator we have, it has a purifier for the feedwater that's all.
Thanks for watching! Take a look here at this video ruclips.net/video/W6iywW0z_eY/видео.html as it goes more into what a DA does.
Simple

dissolved oxygen only

And desolved CO2 too
To avoid corrosion and acidity
