Boiler, How it works?

[@richardwargo5201]

Some comments from someone who's been involved in engineering power plant boilers:
1. Doesn't discuss role of condenser and why it's important. When steam flows through turbines, some of it condenses and must be removed to avoid turbine blade damage. Also, after steam has passed through all boilers, it is cooled and condensed back into liquid, sometimes by using water from a river or lake, sometimes by using ambient air. This significantly improved thermodynamic efficiency of process. Typically, condensers operate under medium to high vacuum to maximize thermodynamic efficiency. Liquid condensate is then recycled back to feedwater pumps.
2. There is significant thermal expansion of boiler as it comes from a cold state to online. Large watertube boilers are suspended from near top; I've seen some boilers expand downward more than a foot (1/3 meter) due to thermal expansion.
3. Because of condenser, you can consider steam piping an "open" process, which means video's treatment of pressure during heating is essentially correct. But in order to reach maximum allowable temperature (limited by turbine metallurgy), water and steam pressure must be high, generally 1000+ PSIA. This pressure is mostly supplied by feedwater pumps.
4. Reason for multiple water passes through hot combustion gases is to primarily extract as much of the heat content from the combustion gases as possible. Economizer preheats boiler feed water using "cooler" combustion gases. Reheater uses hotter gases, superheater uses even hotter gases and main watertube chamber uses hottest gases. Side benefit to extracting maximum heat from combustion gases is thermal efficiency of overall process. The more heat you remove from combustion gases the better; plus it is a benefit to reject combustion gases to atmosphere as close to ambient temperature as achievable. I've even seen places use air to air heat exchanges to preheat incoming combustion air using combustion gases after water preheater.
5. Superheating is your friend. Dries out the steam, which is safer for turbine, plus provides significant thermodynamic efficiency.
6. Boilers generally use air, which has side effect of creating NOx molecules, which are environmental pollutants. This can be mitigated by extending flame length and reducing flame temperature. A newer way is to filter out most of the nitrogen and supply air with higher concentration of oxygen.
7. Everything is interrelated; changes in operating regime always impact something else.

Thanks for taking the time to explain

[@rayhagan1339]

This is an excellent video. I have worked as an operator and now teach power plant operations, as a consultant. I am very impressed with the quality of your video. You might consider revising the narration regarding superheated steam. By definition, steam does not become superheated until all moisture is vaporized. Likewise, it remains superheated until it again reaches saturation. At saturation, there might be some moisture. Below saturation is liquid. Just a small point, but there can be no moisture in superheated steam.
I hope you have been able to continue you work. This is a truly fine animation for teaching.

you are right! we are industrial boiler manufactor in China, have 50+ years experience in boiler making, our official facebook have professional knowledge in boiler structure, running, operating etc, welcome you to visit our facebook page facebook.com/china.sitong.boiler/?ref=aymt_homepage_panel, and my personal facebook no is changhong zhang

Hey Ray, what do you know about advanced ultra super critical technology?

Hi I'm Mahabubul Haque from Bangladesh n working in power sector for foreign manufacturers/suppliers generation, transmission n distribution products marketing through international tender.
In our country there are many sugar mills n there small type power substation.
But we need your support for production of energy in our sugar mills.
I am eagerly waiting for your reply through my email address - [e-mail]

[@cck1496]

Excellent video. Pressure also increases because against a saturation pressure, there is a saturation temperature.

thanks , taking some notes

[@anasmerchant9441]

You put things very nicely it is worth watching your 5 minute video rather than read a book for hour🙌🙌🙌 hats off!!!

[@vishaladityaganguly2889]

Most trusted channel for engineering concept explanation ❤️

[@davidgrisez]

This is an interesting video on the basics of how a generating station boiler works. I worked for 34 years in Los Angeles DWP generating stations. Most of those years I was an operator of the generating station equipment. I also know that there is a lot more that could be said about generating station boilers.

[@rehobothjohn3224]

Thanks, the more videos on this, the better for me. I am taking Power Engineering right now, so the more I see the better I understand how it all works together.

[@aruntechltd9771]

It is very useful video. Any one can understand the concept. Thanks for your hardworking.

[@airlessowl8840]

Gotta write about all of these for my hnc. Thanks for the vid. Very interesting and useful for my thermodynamics unit

[@thewallstreetjournal5675]

The same phenomena happens within Refrigerant pipes. Any pressure differences within the high or low sides off an AC pipe occur due to friction with the pipe surface. Differences in heat content throughout the length of the pipe effect the density off the gases not the pressure of the gas on either side. For this reason refrigerant mass tends to migrate to colder areas.

## 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.

And you could take that 40 degree Celsius water that leaves the condenser and use it to run an turbine that uses ammonia as a working liquid/gas or a Stirling engine. This would especially work if you were next to a large body of deep cold water. Like in Minnesota or Winnipeg.

[@sandipmurmu1967]

You should have mentioned that in case of REHEAT only the pressure dosent increase but falls due to bends in piping arrangement and so does it happens when saturated steam from boiler drum travels through different sort of superheat circuits. But in waterwall its pressure do increase during circulation in drum....

To think about it yes it makes sense that the water pressure in a boiler doesn't rise due to flow. That was interesting.
