Inside a coal-fired power plant (IPP plant in Delta, Utah)

- This is a video tour of a coal-fired power plant in central Utah where I teach each year. It describes the process of generating and transmitting 1,900 MW of power. I hope you enjoy it.
A couple of clarifications: The generator shown at 14:06 is indeed one of the generators (26kV), but the device shown at 15:43 is the exciter for the generator. The generator (alternator) is contained within the massive round portion of the orange assembly shown at 14:06. Also, I gloss over the process of burning and cleaning the coal. The coal is pulverized into dust to be ignited, and the actual "cleaning" is done as part of the process of burning it.
What you showed was only the slip ring assembly. The exciter is on one side, the main alternator is on the other. This conducts the 4000A of DC current into the rotor.
republican poison plants funded by the billionaires and big oil
@@danbam465 , written like a true nincompoop. Fossil fuel power deserves criticism and eventual extinction, but going after it with incredibly uninformed cheap shots is inexcusable.
The "cleaning" is done post-combustion. Indeed, at least half the plant as you have shown it is dedicated to cleaning the exhaust gasses so that they are (reasonably) safe to send into the atmosphere. Virtually all of the white cloud seen coming out of the stack (chimney) is simply steam, and this is because of all the massive electrostatic precipitators, baghouses (filters) and chemical scrubber that are in the exhaust path between the furnace below the boiler and the stack. But no process is 100% effective, so there is always a tiny amount of combustion byproduct that gets through.
The portal where you show the bright light in the "boiler" is not in the boiler, it is in the furnace (true, depending on the design, these can be considered to be essentially the same thing...not sure about the design at this particular plant).
Others have pointed out that the thing you identify as the "generator" is actually just a tiny but of auxiliary equipment near the generator.
The cooling 'tower' (not really a tower at this particular installation) is primarily there to cool the closed loop water/steam/water system so that it can be used again. Many fossil plants don't use cooling towers because instead they use water from a nearby lake, reservoir, or river as a source of cool water, and then through a heat exchanger to cool the actual active water loop.
I write this sitting at a desk at another coal fired power plant, which will remain nameless. My last plant visit before retirement!
I was about to say this same thing! Fascinating video though!
10:22 there is no CO2 cleaned from the coal. CO2 is created during combustion
Yeah, I think the cleaning may be to reduce the Sulphur content. CO2 would be a product of combustion.
Wow this is incredible. Really makes you appreciate the insane amount of time and effort that is spent keeping the lights on. Also, I have nothing against renewable energy, but I wish some of the people who have the attitude that "fossil fuel power is obsolete and needs to go away" could see this video to understand the critical role plants like this all across the world play in providing the power that we all depend on. Great video 👍
I wish they had an inkling about what producing the power for just a small town entails, sadly they couldn't fathom the numbers when it comes to the daily usage of a whole state. I cite the average consumption and what it takes to provide that power and I'm called insane or I'm inflating the numbers. People that are adamantly against fossil fuels don't want to hear real data because their solutions can't satisfy demand and would not be financially feasible to do overnight as they want to believe it can be done.
Nuclear all the way
Nuclear could do the job just fine, and kill a lot less people too
What kind of argument is that? Renewables are bad because coal is being used now and because someones are now dependent of coal? Remember that coal does not last forever. One day, will be the day when easily accessible coal is used. What are you going to do then? I like fossilfs too and the systems are impressive. But renewables make a lot of sense, it just needs to be worked on to make them reliable, cheaper, etc. One of the first things I did when watching this video, was calculating what area of solar panels you would need to replace this. Well, with 20% panel efficiency at minimum it is 9,5 km^2. But because solar panels are not constant power sources and there is no good energy storages, in practice it is much more. But in the western USA, there is area for sure. Actually it is surprisingly small area, have to check did I make an error somewhere in my maths.
@@jimmartin7881 Sun shines at approx 1 kW power per square meter, of which you can recover maybe 20% with a good solar panel. Wind is another way to recover the energy of sun. Problem with these is that, they are not constant power sources. So for the system to work well, would either need massive amount of over capacity, or massive energy storage systems. Currently synthetic gas is maybe one of the few energy storage systems (aside water, where possible), that in theory quite well might have the storage capacity. But for sure, these projects take some time to complete.
The boiler is suspended to allow for expansion of the boiler in a downward direction (3:42). It is a common practice. Steal expands at a rate of 7.3x10^-6 ft per degree, with this increase in size you have to account for that (even though it is not that much ). If it was hard bolted and not allowed to expand it would crack.
Thank you for stating the cooling toward are only emitting steam, its a common misunderstanding that drives me nuts when people assume it is smoke or exhaust from the plant.
@@TomGorman59 Hell, most of everything that comes out of a stack is steam these days. Thanks to Obama's EPA regulations.
But, all of that ash is caught and put into sealed landfills
@@jimlthor Fly ash and bottom ash was used in road construction once upon a time..
I've seen things like push carts and maintenance equipment get smashed from being placed under the boilers when they were cold!
@@rabie4x4 oh, we still sell some of the bottom ash and a lot of fly ash.
Just the ash that used to come out of the stack is captured by scrubbers now
Hi, great video. The high voltage rating of the GE Pittsfield built coreform GSU (generator step up) transformer is actually 345kv (345,000 volts) nominal. Per the HV denergize tap changer ratings of the one screenshot you showed of the transformer nameplate it shows tap position number 4 at 345000 volts
I've been working in power plants but never have got such a great run through every single system in a single place. Great content, thank you.
You really Nailed it to the WALL on this one! and Thanks for not "dumbing down" and wasting Both our times on Tutorials with fancy graphics! there are many other places to gain the prerequisite knowledge and background to get to Your level of instruction (I'd like to think I have) Thank you for your work!
That was the best 32 minute timer watched for a long time
I actually never watch these kinds of videos but the time really did fly fast here.

Go nuclear ! more fun on a carrier.. CVN-70 :) But I can't tell you about it :(
Will they take you out?
At 15:30, it's not the really the "generator" itself, it's the exciter of the generator.
DC voltage (585V/5363A max) is fed into these brushes and goes into the windings of the rotor, who creates the magnetic field.
Agreed. I misspoke.
The power from the exciter goes thru the AVR (regulator) first which controls the amount of power the generator windings pick up from the generator rotor. On startup the AVR is controlled by us control room operators. Once we turn the generator control over to the system operators they control the output of the plants in the system according to system demand and the traders buy and sell power from different systems according market demands. Even though most operating systems in the plant are automatic, we make critical adjustments throughout the plant as system load increases or decreases. Sometimes we have to override automatic systems when things get unstable, and it can get downright scary.. for hours. It's not uncommon to get home physically exhausted from our 12 hour shifts in the control room.
Doing brushgear (replacing all the worn out brushes & cutting them in with sandpaper) was one ofvthe dirtiest jobs I ever did, Carbon dust everywhere, Mike Rowe would be jealous!
For the ge guys , alterrex
Exciter generates DC current to the rotor, not the windings.
Rotor magnetic field cuts stator windings to generate AC emf.
5 million tons per year =/= 1.2 million tons per hour.
The tree huggers love to post pictures of water vapor from stacks and cooling towers and tell people its all pollution that they're looking at..
Im actually often quite triggered when cooling towers are shown as "Chimneys" especially when it comes to nuclear power.
That tunnel at 8:15 had to have been just washed down... or the coal is so wet or frozen that it's not putting out any dust. (I doubt that)
Our stuff in the South gets dirty fast
What kind of efficiency does this have? My wild guess is that the thermal power is probably twice the electrical power, so in around 4MW? I'm wondering why they don't use waste heat from the plant to heat up the railway cars? That heating solution looks like an afterthought. Do they use any of the waste heat for district heating?
500 million tons of coal a year, vs. 100 tons of uranium for four years.
Nuclear looks better.
25 tons of uranium a year vs. 200 Kg hydrogen per year.
Thermonuclear looks *much* better.
@@Muonium1 fusion lmao 😂
It was 5 million, not 500 million....get it right
@@oldmanwinter6773 Check again.
@@lefthandedhardright8839 It's 5 million tons. See video at 2:22.
I have been a paper mil E and I Tech for 30 years. I enjoyed boiler controls more than other process areas. Nice tour. Solar,wind and fairy dust can’t do what this plant can do 24/7!
7:25 thats the cleanest coal tunnel ive seen in a while
10:17 the “scrubber” where the majority of pollutants are removed is after it is burned. its after the gasses leave the boiler before they go out the chimney.
I am not in this industry or even in any adjacent industry but I found this extremely interesting! Great video.
Wow, what a compliment. Thanks so much!
Thank you for the tour. You did a great job of combining quality photos with solid explanations of the components.
I'm very familiar with MegaWatts, and 820 sure is a lot of them. But I forget 1 Gigawatt is a BILLION Watts, the scale is startling to hear out loud.
For real. Throughout the video I was thinking to myself "Ok, those numbers are _too_ big"
Remember, Doc's DeLorean needed 1.21 gigawatts electric to time travel.
I worked for two years in fossil plants. Every day I would go home with fine coal dust in the Crack of my a$$. When the opportunity presented itself I switched to Hydro for the rest of my career. There I went home clean every day.
27:10 I'm glad you mention that. A lot of people in government especially don't take quite seriously the fact that power is a life-critical requirement, and people have died (and continue to die) as a result.
Great tour! That step-up transformer is 26/345kV, you can see the no load tap settings at 18:00 at the top of the screen. Nice EMD 710 V20 gen too. I have a video of one I used to work on of it starting up with air starters. th-cam.com/video/hFVJ9Lhhm0I/w-d-xo.html
Oh my gosh RYAN you are a LIFESAVER this really helped spark my electrician job and my boss appreciates my worn ethic. This video was a very helpful experience for me and helped me learn more about coal plants. Thanks so much and continue with the training videos.
This was a fascinating video on an obscure subject that is vital to everyday life. Thank you for making this video!
absolutely excellent video. i'm seriously considering a career in the DOE as a substation operator. however, i'm terrified of arc flashes and explosions. i was in the marine corps, later a pilot, and have no problems with most dangers, even ones out of my control. but the idea of doing everything right and just blowing up seems a bit ridiculous to me. especially when you're just told to go flip a switch or open something and now it's just your day job to go stand in front of unimaginable power that will either blow up or not. am i being dramatic? i've been trying to learn as much as my electrically ignorant self can via youtube and other sources while contemplating whether to go down this road. it seems like a wonderful career outside of finding yourself in a burn unit with hearing and vision loss, even when doing everything 'right'. it also seems sketchy when the difference between staying alive and not is someone in a control center or wherever pressing a button at the wrong time.
Go for it and you are being a little over dramatic. Been in substations for years, great job and so many different systems to learn. As far pressing buttons at the wrong time, that should never, ever happen. Any time any button in pressed, switch opened, breaker closed etc.. there is a written procedure that is followed and zero tolerance for errors. You will follow procedures yourself to minimize any exposure and no one takes shortcuts. Sure, equipment can blow up, but the amount of equipment vs blown up equipment is tiny. You have a better chance of getting in to a car accident on your way to work.
I'm a big fan of American fueled power generation. It's reliable, inexpensive and doesn't turn off at night.
Very interesting! I heard IPP is going to be converted to gas soon so maybe a follow up to this video on the new plant would be cool.
I help build two of these things, as a pipe fitter, and as you said the video can't do it any justice. There was 24" pipe that was bringing steam from the boiler to the turbine and it was 3.5" thick! And 9% chrome. They planned 100 man hours to weld each one of the joints. It was really cool to work on.
I was surprised that turbine had such a high inlet pressure (2400 psi). Steam pressure on a convention diesel fired aircraft carrier topped out at 1200 psi and I figured civilian plants would run lower.
The cleaning and filtering is after burning the coal.
Thanks for sharing, those beast are truly awesome. I do remember my professor criticizing that putting some panels on a roof is not nearly as complicated as these plants and we better don't forget that if we don't want to go backwards.
Being complicate is never a target in technology. Complicate only means one couldn't figure out a simple way to do something. Complicate technology is less reliable, more expensive to develop, more expensive to maintain, more expensive to use. Sure we people who are interested of technology often like complicate things, but the actual value of complicate technology is always lower if there is simpler alternative that can do the same thing. Complicate things are done because of must, not because it is ideal. About panels; well the complicate part with panels isn't putting them on the roof. They may look simple to a person who doesn't understand them, but massive amount of engineering and brightest minds on the planet have been working on them to make them work. And the problem isn't even fully solved yet as the grid part of renewables is largely unsettled still. How to make the production reliable? Probably large scale energy storage systems, smarter grids, long range transmission lines, etc. will be needed. Even burning facilities may have a place in the long run, it just may be something else than fossils what they burn one day, and as a backup power they will have important role for a long time.
@@wopmf4345FxFDxdGaa20 sure, the kiss principle is a thing.
The value lies not in the complicatedness of these machines.
The point is that we should be careful not to dismiss these machines as old technology and forget about them. There's a huge amount of knowledge in there and we depend on these right now.
I have spent many days cleaning out clinkers the size of houses in these type of units.
Hi refractory man bottom ash demo yuck
Why didn’t they use the steam and heat from the cooling tower to defrost the train? The steam is already a waste energy.
The real reason the boiler hangs is for thermal expansion. The boiler grows downward over a foot
That was awesome, great Tour. Thanks Ryan, I had never seen a power plant in my life until now, greatttttt. Good video.
@ 13:59 We don't light off a boiler with the coal and heat up the boiler an d then add water. Good what to get an explosion. Fill the boiler with water to the proper level, then you light off the boiler.
I was able to tour the IPP facility in the early 2000's. Very cool and everyone there was extremely pleasant and went out of their way to show us the plant. I'd expect with everything that's gone on in the last 15+ years they aren't allowing visits like that anymore. Glad I got a chance when I did - still have the pictures and was shocked we were allowed to take any even back then.
Electricity has always intrigued me even though I really don't know anything about it. I really enjoy learning about the equipment needed for production as I am a mechanic by trade. I have major respect for the folks who maintenance the power plant and the transmission lines and equipment.
Pretty neat. Honestly some of these videos are better than an in person tour.
I imagine that those support bolts extend down to or even into bedrock. 10k ton boiler won’t take anything less to support it
Great video. I'm an operator in a coal station in the uk. Very similar mix of old and new. I think the environment agency is stricter here. We have to have flue gas desulpherisation and selective catalytic reduction retro fitted onto our units. My station is 4 x 500mw units but run at 50hz 3000rpm. Our big motors are 11kv. But it was built in the 50s.
Think of all the wasted heat going to waste to towers when it and blowers could thaw coal cars!
Yes it would cost more to build but would save megawatts lost to the red hot resistors under the cars.
I just questioned that myself, I know we use steam to heat other things before it gets condensed.
Why not use the waste heat to thaw the frozen coal cars?
Tried to get an idea of how big the boiler is...
1 cubic ft of water is 7.5 gallons of water. So that means this boiler is 46,267 cubic feet in volume. Let's say you live in a 1,000 sq foot apartment. That means if your apartment was 46.267 feet tall you could just fit the volume of water that your boiler holds in your apartment (that is empty).
TL;Dr: I've seen ponds that hold less water than this boiler.
Boilers are about 10-15 stories tall ,😁
Very cool video. Someone probably already pointed it out but at 10:30 when he is explaining "cleaning" the coal using scrubbers, keep in mind that it is the exhaust gases from the boiler that are "scrubbed", using chemical processes and electrostatic precipitatiors. When I worked at our local municipal power plant, (a mere tea kettle compared to this monster) the coal came right from the yard, to the day hoppers, fed to pulverizers and blown to the furnace. Cleaning comes after burning.
I'm wondering why they don't just pipe some waste heat from the steam boilers to thaw the trains instead of the 5 megawatt electric heaters.
It's called extraction steam and auxillary steam and it's used to heat the condensate in the low pressure heaters, feed water in the high pressure heaters, mill inerting steam, plant heat, help preheat the air before the air heater. Then what is left over is condensed in the condenser and reused. Condensate is expensive the water is so clean that if you drank it the menerals in your bones would be absorbed now that's what I'm told anyway.
@@nathannesbit887 That same DI water is what is used to cool the windings in that generator and must be cleaned further thru another resin bed or two. That super high purity water doesn't conduct electricity or the water cooled windings could fault straight to ground! Cooling tower water cools this water in a closed loop system via a water to water heat exchanger.
@@rabie4x4 it's also used as a source for bearing cooling water. I'm still fascinated with how water has so many different names in a plant with the difference uses.
Been through so many coal fired plants being a union laborer in the Ohio Valley. This is rather smaller and much cleaner than what I'm used to seeing.
Okay. So you got things a little earlier than when they happen..
Around 10:00... What they do before its burned is run it through magnetic separators to pull any junk or trash out.. (like bolts or broken parts of the train, or any trash that came from where the coal was gathered)
Then, it goes into these GIANT hoppers via a junction tower. It is fed out of the hoppers into pulverizers that crush that coal into smaller than baby powder particles, and is fed into the boiler.
The scrubbers dont come into play until after the coal is burnt. After it is combusted, the ash and gases are sent into the scrubber system and precipitators, then out of the stack.
Some plants use both scrubber and precips, some use either.. but Im pretty sure all have to use a scrubber these days
I am glad you posted. I was thinking the same thing.
Interestingly, the pulverized coal is numerically transported up to the boiler from the pulverizers.
What could be so top secret about burning coal? 🤷🏻♂️🤷🏻♂️
Its the computer management of the plant/ grid it can be used in a cyber attack if the information got into the wrong hands
I've been in "The Control Room(tm)" -- not when the plant was active, and long before 9/11. One could spend hours showing and explaining a power plant. I've had the day long tour of Cliffside (NC) back when it was 5 turbines. It was recommissioned with a massive single turbine long ago. You didn't mention it, but my guide was very keen on explaining why the turbine hall is so big... so they have space to dismantle the turbine for servicing.
They don't filter CO2 out of the coal, that comes _after_ it's burned. The crushed coal (dust) is filtered to remove sulfur and various heavy metals. If they have the proper scrubbers on their smoke stack most of what's coming out is steam. Ash is collected, and much of the CO2 is ("should be") sequestered.
I've been in a few control rooms. Not sure what a bad guy is going to do by seeing a few screens.
And I don't know about this specific plant but I'm 95% sure none of the CO2 is sequestered
Thanks for the great video. I think the 500 kV applies only to the DC link to southern California. The switchyard may be less. The AC to the DC rectifier would need 0.707 times 500 kV, right?
One other point: the fossil fueled power plants will have to be replaced with renewable energy -- wind or solar. The timeframe is about 2035, but there may be efforts to speed that up to much sooner.
It’s surprising to me that they don’t use waste heat to defrost the train cars-surely getting that 8MW for free would be worth it!
The hand-scratched A/B/C on the transformer nameplate below X1/X2/X3 is a nice detail.
I'm just adding things as I wacth.. so I apologize.. As far as the transformers go, we always have to have a spare on site that's got oil running through it.
The last time one blew up, we had to have a new one delivered by train, on the same tracks the coal trains come in on because the roads and bridges couldn't handle the weight.
Is the plant always this clean? My power plant is roughly the same age and looks about 50 years older.
Actually, yes. They take great care to keep it clean. In fact, they hose everything down so often that they have to worry about cleaning liquids more than they have to worry about all the coal!
@@RyanJacksonElectrical I hear stories from guys who have been at my plant from the beginning and it used to get firehosed every night. Reduction in manpower now prevents this.
jrsnowden25 most power plants keep them clean because if coal dust accumulates that can be a big fire hazard
Cooling towers don't produce steam they reject heat and condense the hot air .Stem is produce when adding heat . Your excellent and informative video pretension is bring back old memories .
That's not smoke it's steam! Steam from the steamed clams we're having! Mmmm, steamed clams!
Very interesting. Adds a whole new perspective to the amount of effort, engineering and care that goes into designing the systems that help keep our lights on. It’s scale is absolutely mind blowing.
Powerplants and boilers in general are so damn cool.
Boilers and burning techniques must have been one of my fav subjects to study.
21:55
.
2050HP at only 116RPM....... that requires a HHUUUGGGEEEE!!!!!!! amount of torque..... wow!
Pittsfield Massachusetts....weird to hear. I played baseball across from the abandoned GE plant. Apparently their waste pond glows at night. They had to plastic line it when I was about 14 to prevent ground seepage
Does the Department of Homeland Security REALLY control access to parts of power plants??
Control room access is limited by the National Energy Reliability Council - Critical Infastructure Protection or NERC-CIP.
so is your special field arc flashes? (im an idiot btw) my uncle has a buisness doing electric motor vibration anaylsis, i can just imagine it would take him years to align all the motors and then youd have to start the whole process again right away just out of curisosity, how big is the skelleton crew? around my way its all hydro power, all under 500Mw i can speak for the bigger stations but i know the smaller stations (just under 10Mw combined between upper and lower) has one guy check the bearings for about an hour every fortnight, they also have a 30s/40s Pelton wheel and turbo altinator (was only kicking out 300kw when i saw it, but i also happen to be one of the first consumers down the line from said power station, pretty wicked knowing my power comes from a near 100Yo turbo alternator
I spent ten years of my life at a coal power plant in Arkansas age 18 to 28. Low cost power and good jobs.
When you speak of this security I feel I can’t even mention what I’ve been allowed to do haha. But I’ve been into an old hydroelectric facility, and man, these sorts of places are amazing. The amount of engineering and work gone into it, the heavy equipment and technology, even old technology, it’s all amazing. I know coal gets a bad rap, but man we can’t cut it out of our lives yet, and plants like this are at the front of the technology to keep it burning cleaner. It’s pretty amazing how clean you can get it by burning dust, it doesn’t leave much behind. Hope to see more nuclear, but until the anti coal activists stop fear mongering about it, we have to keep up the coal.
Also the amount of electrical equipment is astronomical, and the fact it’s mostly worked on when live, the stuff that goes on is pretty amazing.
What's interesting is bassically the boiler the coal is ground to a fine dust and is bassically a controlled explosion as well built an airport with structural bolts that same size there a pain to work with
What is the Thermodynamic Efficiency of this Coal-fired Power Plant (Given you're burning 1.2X10^6 pounds of coal per hour, I estimate a Thermodynamic efficiency of 43%)? Does this plant burn bituminous coal or anthracite coal?
The high side voltage on step up transformer (GSU) is 345KV (phase to phase) That info is on the nameplate by high side tap settings chart.
BOILERMAKERS
28:13 *does some math* 400 joules per sq cm ... FUCK. Please tell me that's true calories and not dietary Calories.
I think they just don't want you in the control room. NERC Cyber Security Standards - Controlled Access Area just means that you have to be escorted into that area by an authorized person at all times and be logged.
While they do treat the coal before being transported to the silos, most pollutants are removed by a scrubber on the back end of a unit.
The main reason the boiler is suspended from the ceiling is to allow for the boiler to grow as it is heated. The bottom of the boiler sits in what's called a neck seal. This keeps a water seal between the bottom of the boiler and the pantleg /SFC as the boiler grows or shrinks.
Around 15:35 you are looking into the "dog house" or the exciter room. This is not the generator.
I'm going to assume the control room at 23:57 is for the cooling towers based on the layout.
Just a few notes on your video.
Nathan Nesbit, damn UO’s. So nit picky.
That was so awesome thanks so much it would be cool to see a gas power plant too
Im still so sad that current world situation cancelled our class trip to Natural gas burning powerplant :/
Would have been so cool to see a "Huge jet engine" spinning turbine.
The coal should be delivered "prepped" from the mine prep plant. Our coal yard crushes the coal before belting into the silos.
The reason for the heaters in the thawing shed being 480V instead of a higher operating potential has to do with the dielectric strength of the heating element insulation. Being 480V means that the peak potential to ground is only 392V (peak of 277V RMS; I know it is on a resistively grounded system but each phase is 277V to ground in normal operation). Higher potential elements would require much thicker insulation, which means that the nichrome or kanthal (probably the latter given that kanthal has a higher maximum temperature and the element casings are already running cherry red) wire in the elements would run hotter and thus be at more risk of melting.
Then there is the fact that 480V elements are a COTS item. And on top of the cost of custom elements, any cost savings from smaller wire would be eaten up by the 5.5MVA+ of conversion transformers as opposed to just tapping the extant 480V buss.
That is a GREAT point.
@@RyanJacksonElectrical Also on rewatch, the exhaust scrubbers remove SO2 not CO2.
With steam for that instead of electricity, would the maintenance costs eat up the energy saving?
@@b43xoit Electric heaters are used for radiant heat. Using steam would require building an insulated thaw house and soaking cars in it for extended periods of time. IR gets the cars hotter faster.
Nice video. But this is a small plant. I'm working on 3600MW power plants in South Africa. The things are just huge...
Very cool!! I worked on coal and gas fired boilers for years. I found them fascinating and terrifying. The flue gas monitoring systems were really cool. I wrote an operating procedure for one industrial cleaning company for operating in explosive dust environments after a coal dust explosion killed a couple of workers..... what really scared me though is high pressure steam. It can reach out and kill you without you even knowing it’s there.
To make a quick correction: Eight Hundred Twenty, not Eight Hundred and Twenty.
:/ The CO2 is produced by the combustion of the coal. It's not something that can be "cleaned out" of the coal. It is exhaust gases that we are concerned about when we say that coal is a "dirty" energy source.
Fair enough, I'm just an electrical nerd.
@@RyanJacksonElectrical I did enjoy the rest of the video, and found it to be very informative.
Ironically burning wood and biobased stuff creates more CO2 than coal.
Difference is that burning coal increases total amount of CO2 in atmosphere, while biobased stuff circulates existing CO2.
@@jarskil8862 yeah. Biomass energy production is considered carbon neutral because the co2 just goes back into the air where it recently came from instead of hundreds of millions of years old dead trees.
DHS security rules were nee jerk reaction to 9/11. They don't prevent anything except learning.
What is the reluctance of the coal industry to use scrubbing. I understand there are some 200 plants that do use it & it pipes out very clean stuff.
People from California driving through Utah: "Why are they polluting so much?"
Nice vedio sir, my name Maruti, India, I need clarification on steam blowing.
As a proponent for nuclear energy, I need to understand how the other industries work. This video was educational for me at least if it helps.
So just the excitation is 585V * 5363A so roughly 3.14MW. Am I reading that correctly? Wow!
Boilers are hung to allow for thermal expansion. Water vapor is not steam. IPP units can put out 1050-MW each.
We live near coal, so horribly dirty and harmful to public health with particulate and mercury emission, toxic tailing ponds.
We needed conservation, renewables, batteries.
@5:42, "That's what this guy here is, "The Thaw Shed," you bring a frozen train into that and it's about 5 and a half million watts of fixed resistance heating..." Shrugs it off that this isn't necessarily unlike a 'light bulb' or even typical 'oven' then mentions it's 480V and 5,000,000 watts. lol rothflmao
So Ryan, How many windmills would it take to replace this Power Plant? How large is the overall site in acres? What and how is the 500KVA DC line used?
Utility boilers engineer here is be happy to collaborate with you if you want to do a more detailed boiler review. Water to saturated stream, saturated stream to superheated stream at 1005*F @about 2500psi. Sent to turbine and returned to boiler and reheated to 1005*F @about 300 psi.
Show us a pic of the boiler name plate!!
We need to build more plants.The problem is the out of control EPA---government too big!!St James 1:17.
All water vapor leaving the towers. Steam is indivisible. Thanks a lot friend. SC Navy vet.
Every boiler I have beeen to was byilt from top down and suspended from avove. Thats because of how much the steel expands as the boiler gets to full temperature.
I notice he didn't show how much ash this plant produces. Not just fly ash, bottom ash. This whole process shows why Natural Gas is preferred.
"Clean coal"... WE USE 5,500,000 watts just to be able to unload a train...
I worked at coal fired plant rebuilding the steam turbine.....the place was dirty as hell. Nuclear power plants are cleaner
Finish paying his cell service no either
That transformer alone is probably worth what, 50-100 million dollars?
I got to see the innards of the power plants and turbines of the Lindon natural gas plants, it was amazing to see the steam turbine innards during testing
Where is the plant's 5-story tall high-pressure antifreeze coolant radiator?
The boiler is suspended because it "grows" down when it's running because of the heat expansion.
I wonder how they control the risk of overheating bearings under those conveyor belts setting off the dust.
I'm surprised they don't use bypass steam to thaw the train cars.
A fine example of revolutionary 19th Century energy technology.
I can't believe we're still using coal fired plants. I mean, maybe this is a bad analogy, but I used to play SimCity2000 back in the day and I replaced coal power plants by 1970! I'm just shaking my head at the primitiveness and wastefulness of this. Cool video though.
Silly comment, really. How can you look at all the coal fired plants in service and still say that with a straight face? How can you say such things without doing (apparently) the slightest amount of research, which would easily explain why coal fired plants remain necessary? And if your basis for your statement is because you used to play SimCity, well, that is just embarrassing.
@@youtuuba Stone age technology.
@@coolbluelights , apparently you are just a nonsensical commenter. If you want to make an argument that anyone else will take seriously, at least try to be informed and make reasonable statements. I know a lot about this industry, first hand, and I can say that there is more modern technology at work in currently operating fossil fuel plants than there is in any of the more recent crop of renewable power generation systems. And I say that as somebody who agrees that fossil fuel powered generation of electricity needs to go away as soon as it is feasible to safely do so without the kinds of things happening that have recently been plaguing Texas.
If you just blurt out "stone age technology", that reveals you as being an ignoramus, not an informed person making any kind of valid statement.
@@youtuuba i just think it's funny that you're so triggered by my ignorance.
@@coolbluelights , fools and ignorant people often DO find unfunny things to be funny. The conversations here should be serious, with people weighing in with serious, informed comments, or at least professing their ignorance and asking others for information and clarification. But there are always people who just blurt out lazy, poorly worded and thought-out nonsense, and those comments cloud otherwise decent discussions.
