Talk:Deaerator

Deletion of "Position in turbine cycle" section
Deaerators are used for many types of boilers and steam generators such as waste heat boilers, gas turbine cogeneration systems, large petroleum refinery and petrochemical plant utility boilers, thermal power plants (or power stations), and many others. The diagram in the subject section (Image:Dores-Turbine Cycle diag1.png) applies only to the use of dearators in thermal power plants and would mislead unknowledgeable readers into thinking that deaerators are only used in power plants. To include additional diagrams for all the other types of boilers and steam generators would be impractical.

Also, the diagram (Image:Dores-Turbine Cycle diag1.png) really is not needed at all. The deaerator diagram (Image:Dores-Deaerator diag1.png) which is included in the article is all that is needed ... and it is the most commonly used type of deaerator for all of the above mentioned types of boilers and steam generators.

For the above reasons, I am deleting the subject section. For those who are interested, the diagram in Thermal power station and in Fossil fuel power plant shows where the deaerator is located in power plants. - mbeychok 04:46, 27 May 2007 (UTC)

Are the edits by Berkeley Lab on June 12, 2008 advertising spam?
On June 12, 2008, unregistered user Berkeley Lab made some extensive edits to this artcle and those were the only edits he ever contributed to Wikipedia. In other words, he entered Wikipedia, made those edits and then left without making any other edits or contributions anywhere in Wikipedia.

The edits essentially consisted of adding material about the spray-type deaerator manufactured in the Netherlands by a company called Stork (also called Stork Thermeq). Some of the material is word-for word the same as various online advertisements by Stork. For example:
 * In the 2nd paragraph of the section "Spray-type deaerator", the sentence starting "... Under all operating conditions, the sprayer..." throughout all of the rest of that paragraph is a word-for-word lift from this online online Stork advertisement.
 * The diagram of a spray-type dearator added into that same section is also a direct copy of the diagram in this online online Stork advertisement.

After surfing around to various other Stork online advertisements, I found some other similar word-for-word lifts.

Without making any judgements as to the merit of Berkeley Lab's edits, I am concerned that they were made simply to advertize the Stork deaerator. Unless there are some objections made to my doing so in the next few days, I intend to revert those edits and replace them with a more benign discussion of spray type deaerators. Sorry to be so long-winded. - mbeychok (talk) 06:19, 14 July 2008 (UTC)


 * Since no one has posted any objections to my above planned action and since this article has been slowly degraded by too many revisions/additions that were not "blended in" very well or were somewhat irrelevant or unnecessarily too detailed, I have revised and reformatted it extensively. - mbeychok (talk) 19:49, 21 July 2008 (UTC)

ChNPP: About that poor photo you keep injecting into this article
Please stop. If you continue to upload inappropriate images to Wikipedia, you will be blocked.

User:ChNPP:

Are you deliberately trying to be obnoxious by your repeated attempts to inject that very poor photo of a deaerator into the Deaerator article? Your attempt to hide your activities by making it appear that your sock puppet User:217.5.204.78 is making those repeated revisions really doesn't work ... its rather childish of you, isn't it?

That photo adds nothing to the article. Please be an adult gentleman and remove the photo yourself. mbeychok (talk) 00:03, 28 December 2008 (UTC)

Poor photo
User:Mbeychok is perfectly right. The lighting for that photo is very bad and that makes it almost impossible to see what it is. I am deleting it. Steamplant10 (talk) 21:14, 28 December 2008 (UTC)

carbonic acid in deaerator
The statement "It also combines with any dissolved carbon dioxide to form carbonic acid that causes further corrosion." (after the note about oxygen) is not accurate. The article about carbonic acid shows that carbonic acid is formed by the combination of water and CO2 (H2O + CO2 --> H2CO3), and oxygen is not involved in its formation. I would propose to delete the sentence at this location, and add a sentence like "Under the right conditions, a deaerator can also strip out dissolved carbon dioxide, which combines with water to form carbonic acid that causes further corrosion". With the "right conditions", I mean a sufficiently low pH, because at high pH values, carbonic acid will be dissociated and it becomes very hard to strip out CO2.

Deaerator
Question: Why is Deaerator elevation important? — Preceding unsigned comment added by 97.79.96.177 (talk) 13:46, 16 January 2013 (UTC)


 * Other than providing sufficient NPSH (Net Positive Suction Head) for the boiler feedwater pump, there is no other requirement for elevating a dearator that I can think of. mbeychok (talk) 16:36, 16 January 2013 (UTC)

Deaerators
Deaerators are used for purposes besides preparing boiler feed water; they are also used in the food industry to remove dissolved air in food products to limit oxidative damage during storage. Does anyone want to look into this?

Chelating agents as oxygen scavengers
The chelating agents EDTA and NTA are cited as oxygen scavengers in this article, but to my knowledge these are commonly used in boiler feedwater only as scale inhibitors and corrosion prevention agents, not as radical oxygen scavengers per se. There is no source cited. What is the basis of their inclusion? 108.21.187.76 (talk) 02:50, 16 September 2013 (UTC)

Bias in favour of Stork
The content and references seem to be heavily biased to the Stork company. For example, Stork isn't the only provider of single shell deaerators, but the article seems to imply this. The content should be revised to a neutral point of view. --Pakaraki (talk) 06:04, 1 September 2018 (UTC)
