With the ID fan pulling a draft through the boiler you can actually open the inspection doors and see the fireball. Using a welding mask to see is even better! Thanks Savree, very knowledgeable.
I was looking to see some details re marine water tuve steam engines and all is clear. Thanks for this, the models are great. Thanks for spending the time and effort to create this video.
Thank you so much for the excellent explanation. In fact to understand how a Boiler works is not complicated , what happens is that it's very difficult to find a real good teacher
Thank you so for the explicit details and the contents you create. Your tutorials have been profoundly helpful for me while preparing for an interview for a coal fired super critical power plant
Excellent video! I work in the power industry, primarily concerning the boiler and piping support structure. Fun fact. A good rule of thumb when it comes to thermal expansion of piping (A335, P22, P91, etc.) is that 100 feet of pipe at 1000 degrees F will expand 10 inches along its length. All of the support structure (including the boiler, which is hung from the top) has to accommodate that expansion. Looking forward to your next video!
Bravo. Excellent work on the details of the implementation of a boiler. Learning from diagrams in a book can only take you so far; this was an excellent demonstration.
Great video. I ran water tube boilers aboard ship for many years. Babcock and Wilcox and Foster Wheeler. We used bunker C fuel oil. On Shore as an engineer, I operated fire tube boilers using bunker C oil and natural gas, and sometimes diesel.
As a Student now one taught me better about boilers this much clearly , What an exccelent way to present , If I had money I would have enrolled in many of your courses . Thanks for making this video and making this amazing 3d Model

I have been in the industry since 2004 till present (2023), operating various types of boilers, from solid fuel, liquid fuel and currently gas fuel. In Msia, one need to have competency given by authorities to be in charge of the boiler, which is 2nd Grade Steam Engr and 1st Grade Steam Engr. 1st Grade is the highest. Being a 1st Grade Steam Engr, I found the information shared in this video is accurate and 100% correct!... Thanks for sharing this to all of us...

Very good explanation. Really good work on the 3d model. I came across boilers many times, during my academics but never understood it properly. After watching this video, it has helped me clear all my doubts. Thank You.
excellent work!! A few small remarks; in the gas phase of water, be it saturated or dry steam, water is always going to be in the form of water molecules. when the steam is wet, then we have tiny water droplets in there. But, the molecules are still there. So to state that we have to get rid of the water molecules is incorrect. We have to get rid of tiny water droplets (so, many millions or billions of water molecules coagulated together.)

Great Video but ther might be a small mistake, 15:12 steam is still made out of water molecules. When you start with pure water molecules, they dont react to form another molekule (mostly, it might be that 2 H2O = OH + H3O equilibrium changes a bit). Water molecules is maby a field specific term, but as far as I understand it, is what you mean, that we can only see the liquid phased dropplets suspendet in the gas. The gas is still made out of 100% water molecules. Still great to see the the real struktur, behind the theory.
Thanks for the great video. Could you work with us as a consultant for constructing a water tube boiler for 3Mwe production? We need some drawings and some advice /guidance. We already have experience in smaller projects.
Really interesting. One question regarding combustion control/safety. There is a flow of vaporized fuel AND hot air coming from the pulverizers. How is a backfire prevented, either from the fire travelling from the combustion chamber into the nozzles or from an ignition source within the pulverizers. I could for example imagine, that pulverizing is quiet violent, so there might be sparks, electrostatic discharges or simply parts that get hot enough
You made easy to understand...one doubt the secondary air which goes to windbox do that being heat exchange ?if yes from where Bcz primary air get heat exchange with APH what about secondary air
Interesting video. I used to work on boilers and this one is fairly similar, except for the placement of some items, like the steam drum, reheaters, and superheaters. Feed water was also not as high pressure as this case, but every boiler is different. I really wished you would have talked about steam pressures in this video. For example 850 primary, then 450, 165, 75 coming off the generator for ancillary systems.
The Shoes are Undersized for U.S. Sizing standards. If one walks on and puts his full weight on only ONE nail, the Kevlar will not stop that nail from penetrating the shoe to the foot !
Let me see if I have this correct. Steam is an odorless and colorless dry (0 water molecules) gas but in order to get steam, liquid water has to be heated to boiling (212° f/100° c at sea level), changing the liquid state of water to become vapor water. All the white stuff we see rising up from boiling water is visible vapor water commingling with steam but isn't steam. However in order to produce steam, water has to be boiled. So where does steam come from? Are there other ways to get steam aside from boiling water? What happens to steam once it cools below boiling point? Is steam just hot air? Oxygen, nitrogen, carbon dioxide, xenon, neon, helium, hydrogen, all the Nobel gases...now I think about it, aren't all gases colorless? I can't say if they're all odorless (carbon dioxide isn't odorless) but I don't remember ever seeing gases before without the use of (I think it's called a ----->) spectralgraph or by using electricity to excite the gas contained within a glass tube. Acetylene is another stinky gas, man does that stuff smell bad...and so does methane. Give me a minute and I'm sure I can remember some others that reek.
This is a good illustration, but having worked in powerplants for 30 years there are some design flaws that do not add up or would make this boiler hard to operate. The narrator did not mention the function of the coal feeder which is the equipment between the silos and pulverizers. They control the flow of coal to the mils. The burner arrangement is not of any boiler I have ever seen. Normally a pulverizer feeds one or two rows of burners along the width of the furnace to distribute the heat evenly. This model has burners arranged in columns which will cause localized heating on one side or the other. Some Riley boilers have burners in front and rear fed from the same pulverizer but heat the furnace evenly across. The secondary air ducts come in on the sides so that both forced draft fans can provide combustion air to both the front or rear windbox. In this model if one FD fan is not in service only one windbox is fed air from that fan. And lastly, there is normally no flue gas flow through the penthouse which is the roof section on the top. That area is where most of your headers and desuperheaters are located and no gas flows around them to protect them from direct heat. Other than that, the explanations are very good.
This design is pretty much the same as my old local coal plant, and most UK plants from the late 60s/70s. Look up on TH-cam for "Didcot Power Station 500 MW boiler just warming up" there's a video of inside the boiler and it matches this. Actually most UK plants had 48 burners arranged in banks of 24 each side.
@@edwardbyard6540 Thanks for the info. Yes, that B&W boiler has horizontal burner elevations which allows warming the boiler evenly as I mentioned. If you look at the model, the coal conduits from the pulverizers feed burners in columns, not rows... that is not what I have ever seen in wall fired B&W boilers, Foster Wheeler, Riley, or even tangential fired CE boilers. I'll leave it at that, no harm done as it serves it's purpose of educating. Cheers!
