Wow! it takes some 4 Million horsepower to generate 2900 Megawatts....in a perfect world with no losses. Thank you for maintaining and supervising your emissions systems. Clearly, most of the public has no idea how ''clean'' your plant is as compared to earlier coal fired plants. In fact, the public has no comprehension of the magnitude of designing, building, and operating a power station such as yours. Electric Power Distribution falls in the realm of magic for most citizens.

There is a ton of misinformation in the comments regarding alternative energy sources. So, just to be clear; 1) All conventional thermal power plants operate exactly the same way. The only variable is the source of the heat: nuclear fission, combusted fuel, concentrated solar radiation, etc. Every single one uses the same turbine, heat exchanger, induction generator, heat removal fluid (a water mixture). 2) The reason we don't just switch to all solar and wind generation is because there is no good way to store energy. We don't use the same amount of power throughout the day; there is a huge spike in demand in the afternoon through late evening, and very little usage at night. This is called demand response: the grid must be able to quickly adapt to large surges in energy demand within minutes. Most renewables (save for hydroelectric damming) just don't have that level of flexibility. If the sun isn't shining, your photovoltaics aren't on. Thermal plants have been time tested to be able to respond to these fluctuations. 3) As some have pointed out, there is some type of balance to strike between electricity sources. Supplementing traditional thermal plants with alternatives is the only realistic way to meet our modern energy demands. That is, unless we can find a way to store excess energy produced in low demand periods (this is particularly important for wind). 4) Moreover, the small scale cost of solar panels and wind turbines is very appealing but the scaled cost of operation ($/MWh) is laughably outrageous compared to a nuclear or coal-fired thermal plant due to the energy availability factor (EAF) alone. TL;DR In sum, coal plants won't be gone any time soon, and there is no silver bullet "just use x" solution at this time, primarily due to the lack of proper energy storage and redistribution technologies.
I won't deny that solar and wind are extremely expensive in comparison, but to say we don't have any good way to store electricity from alternative sources just isn't true. We've been doing pumped energy storage since the late 1800s, it's very reliable, fast in response and with very little loss. While pumped storage won't work smack dab in the middle of the Great Plains or something, modern power distribution means you can build it pretty far away from where you'll be needing the power. Also, the advances made in the field of flywheel energy storage makes it so storage facilities can be (and have been) built with a realistically reasonable budget. They'll lose some power over time, but it won't be an appreciable amount between the moment the excess power is stored and the time it is needed to meet peak grid demands.
You can store solar heat in water at high efficiency and low cost and extract that energy using a closed vacuum steam turbine and condenser system with degassed water.

People are always fascinated (as was I) at the amount of coal used every day at one plant. What isn't reflected in this animation is the massive energy demand we have that has created this coal gobbling industry. We make a ton of electricity because we use a ton of it.
I've been in the power generation industry for 30-years, and this is the best overview of coal-fired power generation that I've seen. It's very well done. I follow-up with one for natural gas fired, combined cycle, which has twice the efficiency, would be a great addition. But I'm sure something like this is very expensive to produce. Keep up the good work.
In Helsinki /Finland at Vuosaari power plant we have such a combined gas turbine + steam turbine system producing electricity + heat. The el. efficiency is 60 % and still it gives much heat for heating buildings. Bio gas of organic wastes is used in a combined diesel motor + orc-turbine giving el. + heat energy.
So much was left out. You cannot just use chlorinated river water for the steam. Those turbine blades would be destroyed in no time. That water needs to be clean and pure for when it’s turned into dry superheated steam. Those turbines run with steam at 3000lbs of pressure at 1005°F. So much more into it then what was said here.
Thanks for the comment. Since this is a general overview video, not a tutorial on how to operate a power plant, so there’s obviously many details that couldn’t be included. But your comment does bring up good additional information. I appreciate you adding that.
@@edpvideo I get that, but even for the “simple” explanation I personally would have added something simple like “use river water that is then purified “ and go from there. It was a decent explanation though.

Carbon monoxide is already dealt with. It is emmitted at levels that are "below detectable limits". They will use CO catalysts that reduce it to basically 0.
@NathansHVAC For fuck sake, Miller burns ~30,000 tons of coal daily. At $50/ton, that would be $1,500,000/day. Those fuel costs have to be passed on to customers. So, fuck off with that coal is cheaper bullshit. Keeping a similar nuclear plant fueled would cost about $9,000/day. Of course, hydropower and geothermal (which can be used for baseload) have no fuel costs. A similar combined cycle natural gas-fired power plant can be fueled for $3,241.72/day.
This is glorious, I been tryin to find out about "how to make your own electricity with water" for a while now, and I think this has helped. Have you heard people talk about - Kiyenry Meyharlotte Release - (do a google search ) ? Ive heard some unbelievable things about it and my mate got excellent success with it.
Really appreciate this video. This helped me gain knowledge of power plants so I didn't sound like a complete dummy in my latest video "Going inside of exhaust side of a turbine" Thanks!
This is a very good video which explains the entire process involved in producing electricity from coal. Wallboard is a very useful by product of this. It is rather alarming how much coal is needed to keep a power station going.
re: "It is rather alarming how much coal is needed to keep a power station going." Look mate, 2900 Megawatts is a BIG DAMN PLANT too! One of the larger coal plants, and on a par with big nuke plants too!
It may shock you to learn this but water boils at 30c in a vacuum and returns to liquid at 29c the expansion rates are the same no matter how the water boils. This means in a closed system you can run a steam engine off heat from the sun and endothermic from water sources you could even run an air conditioner use the heat to boil water and the cold to return it to liquid.
SHAZAAM! "Build it and they will come." Meanwhile progress on Dr. Mills' SunCell (tm) reactor (uses Hydrogen in a novel way) is going commercial the next year or two ...
"Clean energy" cannot stay near the word "coal"... Anyone can say its energy production system is clean than another, but the real pathways to produce really clean energy are very few, and sure coal is not one of these. I appreciate though the great amount of technology and engineering involved in this kind of plant.
Really? The West County Energy Center in Florida was commissioned in 2009. It is larger than any coal-fired plant in the U.S. at 3,750 megawatts. It burns no coal. Instead, it burns natural gas. Unit 3 at the Vogtle nuclear power plant is 96% completed and will be completed soon. It's sister, unit 4 will follow soon after. When all 4 units at Vogtle are running, it will be the most productive power plant in the U.S., producing about 37 Twh of electricity yearly.
This power plant is literally the largest single point source of greenhouse gas emissions in the United States. Like the entirety of the us Industrial complex, this is the single biggest emitter.
Electricity is not the clean energy people are fooled into believing it is. Almost all of it is made from coal fired boilers, that turn turbines, that turn alternators and generators. I will stick to conventional vehicles. They have a much higher range per energy unit, thus, pollute less per energy unit for work done. The lithium mines are real planet killers also. Nothing grows there.

I do love any 3D animation videos on industrial processes, so thanks for that, interesting to see. However, call me a treehugger if you will, yet it's difficult to shake the feeling that this is an outdated and dirty method of electrical generation. I'm not saying anything about any other form of generation. I read the comments; I'm not interested in arguing. I'm just saying I highly highly doubt we will be generating electricity with these methods far into the future. I'm glad there are other advances in all fields, including fusion.
I know the fly ask can be used for cement but what can the bottom ask be used for? Saw a video about a Canadian coal fired plant where the bottom ask didn't seem to have any use? Anyone know what bottom ask can be used for?
I realize it may be hard for some people to grasp, but the steam temperature is indeed 1000 degrees F and 2400 PSI leaving the superheater to the HP turbine and then sent back to the boiler and reheated to 1000 degrees again and 525 PSI going to the intermediate (IP) turbine. Saturated steam such as 400-600 degrees would do great damage to the turbine.
@@maksimmuruev423 Sometimes the steam waste heat is used. Like in New York City's steam heating system. Most of the time though it's easier said than done to figure out a way to efficiently reuse the waste steam heat.
@@maksimmuruev423 What is a green house going to do with 500,000 lbs/hr of steam that is at 2 psia (atmosphere is 14.7 psia)? It is also around 90 F when it enters a condenser. Also need to consider that the condenser is where the vacuum is formed but the collapsing of steam into water. I cant remember the ratio off hand but it is something like 1000:1 in volume. This vacuum helps pull steam through the later stages of the steam turbine and greatly increase the power.
@@maksimmuruev423 You must not have any idea of the magnitude of energy those cooling towers are handling. In NY all the fish in a river were suddenly dying, the investigation found out the water from cooling a coal power plant heated the ENTIRE RIVER enough to kill the fish. Also in Alabama they do not need any more heat for their plants.
Because in the wonderful world of Democracy people who have absolutely no Idea on how nuclear power generation works, or the vigorous safety standards in place for nuclear power, get just as much of a say as anyone else. These idiots are the one who go onto pass legislation, and pump out moronic propaganda like "MuH 3 MiLe IsLaNd!!!! Muh ChErNoByL!!!!!!! MuH LitErAlLy A NuClEaR bOmB!!!!!!!" In sort the arrogance and ignorance of the common man is to blame for demonization of Nuclear power.
my opinion is that the combination of the movie "China Syndrome" and the coincidental timing of Three Mile Island'a incident contributed greatly to nuclear's resistance. Since then, now 4 decades later, we've (US) lost thousands of nuclear engineers. In my experience, the cost to develop a new nuclear power plant due to regulations just are not worth it. Even converting coal to natural gas is highly cost prohibitive. Cheapest way today to generate 2 Gigawatts is greenfield combined cycle natural gas. Several are being built close to natural gas source in the midwest.
That was VERY interesting and well explained. Can anybody here explain why the water is cooled with water towers? Why wouldn't you resend the hot water back into the boiler with all that residual heat rather than cooling it first? I got lost there.
The water that is cooled in the tower is not the water that goes back into the boiler. The water going to the boiler is in a closed loop, and must be condensed through the cycle. The other water used to condense the steam gets hot itself, and must be cooled in the cooling tower so that it can go back and condense more steam.
The core concept is 'hot gas makes wind and moves fan'. I believe the steam must first be cooled because it is the difference in temperature than enables the gas to move at all. If you just had hot gas throughout the system, movement would be zero (or at the very least drastically inefficient). If I'm not mistaken, the larger the delta between cold water/hot steam translates into greater efficiency/less losses since the fluid 'wants' to move more as it expands more dramatically. I am no expert on the matter, however, and would gladly be corrected by someone who is better educated on the topic.
Power Engineering student here. The water in the cooling towers is a closed loop and does not directly touch the feed water. It removes the heat from the steam leaving the turbine and condenses that steam back into water. The water used for cooling is of very low quality (chlorinated river water greater than 2000 ppm) whereas the feedwater in the boiler is of very high quality (less than 15-20ppm and with many added chemicals to prevent scaling and fouling of the boiler tubes). The temperature of the water entering the cooling tower is roughly 100-105F and leaves at roughly 85F, it enters the condenser at 85F and leaves at roughly 100-105F. The only purpose for the cooling tower is to cool the closed loop cooling water system. Basically the feedwater and cooling water loops are separate and the water does not mix at all. the cooling water is only used to condense steam in the condenser in order to be able to pump the water (you cant pump steam). an auxiliary cooling water loop is used to cool stuff like lube oil and other equipment that needs water cooling.
Hmmm. Good eye. I'm guessing that was an oversight during production. I'd honestly have to look at reference videos and photos taken on site to know for sure.
? Why do the water vapor towers not have a turbine/generator at the top of them or throughout it? ( having more surface area will increase the amount of water that gets collected at the bottom, it also creates another point of power generation in the same system. Windmills completely depend on outside air, having it in the vapor tower makes it's run at all times and gets extra power output when the wind blows.) Ps. Lol that's really a question I love to learn so plz explain if you can =) and I know I'm horrible at grammar =)
@@edpvideo that's right but we are mostly busy with some pipelines to prefabricate and fit it wherever should it suppose to be. So there is also our job to keep or rebuild the pressure vessels and lot of stuff which it belongs to a power or chemical plants too
Actually located in Jefferson county Alabama, adjacent to the town of west Jefferson .Quinton is in Walker county Alabama the post office is located there.
Coal power is eco hostile regardless of how hard we try to clean the exhaust but, the engineering is brilliant though. The future is wind, solar, wave, and LFTR. LFTR stands for liquid fluoride thorium reactor.
@@FowlorTheRooster1990 In the long run yes. But the details aren't worth fussing over. All nuclear is so much better than all fossil that any of them is a worthwhile upgrade. Breeder reactors shouldn't be the top priority until we're sure they can operate cheaply and reliably.
Well, the generator water is already a closed system. Replace the boilers with two thorium 232 reactors and get rid of all the complicated mess dealing with pollution.
In response to the last message you cant pump steam. I often wondered this apparent loss of energy. But having worked at 1900 mw power plant for many years this is one of the inefficiency's of the process. Attempts have been made to use this heat source to heat green houses etc. The results are not cost effective. This video tells it like it is.
Not enough in the presentation in the transmission section. I always assumed 25kv or so from the generator output was put into a step transformer as they said, but wanted to know more, as I'd heard that the high 400kv voltage in the step up transformer went through a spark gap. Then, it goes on a slasher for the 50 or 60 timing. It's transmitted out as a DC pulse, supposedly at high frequency like 55khz, with a 50 or 60 slash. Gerald Morin was explaining in this in his videos. How does a steam turbine maintain the 'exact' 3000 or 3600 rpm to maintain the 50 or 60 hz output? Also, the power generator itself couldn't produce enough power, unless it runs faster, then the power is converted later in the line. I'd like to know more about how the pole transformers work. They receive the 'transmitted' line, no neutral, which is grounded to earth at each end, the live wire terminated in the can itself. Also, burning coal is very inefficient. Peter Davey invented a device that heated water up immediately, just using acoustic resonant sound waves. Also water could be used, by splitting it into hydrogen from oxygen, then using the hydrogen gas to heat the water. The burning temperature of the hydrogen would need to be lowered down, so the gas doesn't burn through anything. It's impossible to transmit.. current over the grid, so the current along with the 120 or 240 50/60hz is done from the pole transformer itself.
Once the generator synchronizes to the grid the frequency of the grid keeps it locked in. These turbines also have governors to maintain the speed. Now the watts are controlled by the turbine once the generator comes on line. Watched generators go on line many times in my career. Always fascinating to watch.
@@odongemma4170 Unless you electrify transportation and even find a solution for more effective mining. Today's problems aren't necessarily those of tomorrow.
@@antonellaromero_upc1564 Well 95% of nuclear waste can be recycled and the total amount of heavy toxic nuclear waste dramatically decreased. We also need to compare the volume of waste: the generation of electricity from a typical 1,000-megawatt nuclear power station, which would supply the needs of more than a million people, produces only three cubic meters of vitrified high-level waste per year, if the used fuel is recycled; the volume of CO2 from an equivalent coal power plant is, as you can imagine, significantly higher.
you can step up as much as you want, the thing that you need to care of is that with higher voltage the electrons can jump further, so you'll need higher electric cables, bigger transformers, bigger circuit breakers, etc... this might not be worth here you can see a 1.1MV transformer capable of transmitting up to 12GW th-cam.com/video/0pGH1B863oI/w-d-xo.html&ab_channel=EngineeringWorld
@@edpvideo They use natural gas or oil ignition torches to ignite the coal-air mix, the torches in turn use spark igniters to get started. They sometimes use the ignition torches at low load to make sure the coal still ignites reliably.
Yes, They use light oil like a diesel fuel to get the boilers started until its heated enough for the coal to be used. Especially if it’s been shut down for service.
Ahh, so that raises the question: Since you appear to use electricity just to get things moving and grinding before you can boil and generate, how do you boot a place like this up? I mean... if it somehow lost the grid all around, or if it were the only one on a specific grid. Does it have diesel generators to give it its boot-up power for that?
if you had to, you could use force multiplication (gears and lever arms) and use a few humans to crush enough coal for the furnace to fire for 20-40 minuets, which would be enough to restart and accelerate the crushers to operation speeds.
Small plants have diesel back up. Some will use a simple cycle combustion turbine, jet engine, some will use a smaller auxiliary boiler as a small one is easier to get going and use it to start the mains, and others simply go offline and stay that way. Many plants do require cranking power. In the restoration plans a transmission operator will have designated certain plants (or units in a given plant) to be "black start". Meaning they can start with no external power source. They will come up, or designed to remain online through special protection schemes, and they will work to get a power path to the other plants that are able to come up quickly. This is all planned and practice. I have done simulations myself.
It's nice to actually watch one of these when it's _fact based_ and created by the people who are actually running the process. It gives me something to reference when I run across other videos that are full of detritus and guessing, and where people in the comment section are losing their minds about all the "pollution" coming out of the stacks, when in fact, it's *steam* that they are seeing. People can be such IDIOTS...
Lol. I won't comment on the idiots part, but what I will tell you is that you are delusional if you think that's steam coming out from the stack. Steam is only coming out of the cooling tower... what you see in the stack includes a bunch of other harmful and hazardous gasses such as the remaining 5% SO3, a ton of SO2 which the limestone doesn't scrub, plus CO and other compounds. I totally understand that this is needed for us to survive, but we need to start adopting the alternatives fast rather than sticking with this old, out-dated, and pollution intensive power generation.
Where I reside, enormous coal trains come into a station that coal fires enormous furnace that boil water into steam. The steam turns lots of turbines that turn enormous alternators. The power is then distributed to station that step down the voltage.
Yes, it refers to the effects that happen when energy is created if you burn something you have smoke and ash to deal with nuclear you have waste products and so on. But you can get clean energy Boil water in a vacuum convert the heat energy to kinetic and electrical with a turbine the water will condense after that maintaining the vacuum.
re: " I believe nuclear power is the future with generation 4 reactors" Potential "stranded assets" once the SunCell (tm) is produced in volume. This is something you REALLY should check out. There is a Reddit discussion group too.
Dave George the condenser operates at a vacuum, below atmospheric pressure. This is to extract as much power as possible from the steam before returning it to the boiler.
Eddy De Paepe sorry boss but natural gas is a cheaper, cleaner, requires less maintenance, staff and can achieve a lower emissions at a greater efficiency. Natural gas can also be regulated to meet demand where as a coal fired plant has to produce a base load even at times of lowered demand. Carbon capture also reduces a coals units efficiency by about 1/3 as the sequestration and compression stage of the C02 collection is extremely power hungry. When government coal subsidies eventually come to an end coal plants will cease to be sustainable.
Chernobyl station by itself wasn't so bad after all units 1,2,3 worked just fine. The main problem was in assholes who controlled the reactor. Actually, Fukushima shows the same issue... operators don't know how exactly work everything inside which is crucial for emergency control. And all of this besides just engineering problems which of course always are lurking somewhere.
Alberta, Canada produces most of its electric power from coal. However, a major move is underway to phase out coal in favor of natural gas. Wind and solar are increasing as well and, down the road, geothermal and small scale nuclear may play more of a role in electricity production also.
re: "and, down the road, geothermal and small scale nuclear may play more of a role in electricity production also." Not so fast there ... you're overlooking what is being done at such companies as Brilliant Light Power and their harnessing of the Hydrino in what they call their SunCell (tm) reaction devices, basically, using Hydrogen 100 to 200 times MORE effectively ...
Why do you have to cool the water. It takes a lot more energy re-heating it from cold, instead of just topping it up with a little heat from the boiler?
Because water expands 1600x when converted from a liquid to a gas (steam). In a contained space that equals 1600x the pressure. It's that pressure increase that moves the turbine blades, not the fact that it is steam. Once that pressure is released/expended into the turbine, it is just steam, not high pressure steam. It must be cooled back into liquid form in order to reduce it back to it's 1600 times smaller liquid form, so that you can reuse the same clean/purified water in the closed loop system. And keep in mind that you're cooling it just enough to liquefy it..
You can't just dump boiling water into the river, it would do greate damage to the plants and animals.. Anyway, the boiler water has additives to prevent corrosion of the pipes and turbines. Can't dump that into the river either. That is why they use a closed loop system and use evaporative cooling.

Thanks for the comment. Since this is a general overview video, not a tutorial on how to operate a power plant, so there’s obviously many details that couldn’t be included. But your comment does bring up good additional information. I appreciate you adding that.
@@edpvideo I get that, but even for the “simple” explanation I personally would have added something simple like “use river water that is then purified “ and go from there. It was a decent explanation though.

Carbon monoxide is already dealt with. It is emmitted at levels that are "below detectable limits". They will use CO catalysts that reduce it to basically 0.
@NathansHVAC For fuck sake, Miller burns ~30,000 tons of coal daily. At $50/ton, that would be $1,500,000/day. Those fuel costs have to be passed on to customers. So, fuck off with that coal is cheaper bullshit. Keeping a similar nuclear plant fueled would cost about $9,000/day. Of course, hydropower and geothermal (which can be used for baseload) have no fuel costs. A similar combined cycle natural gas-fired power plant can be fueled for $3,241.72/day.
Great presentation, very informative.
Thanks for your video. I will use the video in my Thermodynamic class.

This is a very good video which explains the entire process involved in producing electricity from coal. Wallboard is a very useful by product of this. It is rather alarming how much coal is needed to keep a power station going.
The amount of coal used is astonishing for sure.
re: "It is rather alarming how much coal is needed to keep a power station going."
Look mate, 2900 Megawatts is a BIG DAMN PLANT too! One of the larger coal plants, and on a par with big nuke plants too!
this is incredible. makes you really appreciate the people who keep our country running.
Right. We use so much of it that it's mind boggling.
It may shock you to learn this but water boils at 30c in a vacuum and returns to liquid at 29c the expansion rates are the same no matter how the water boils. This means in a closed system you can run a steam engine off heat from the sun and endothermic from water sources you could even run an air conditioner use the heat to boil water and the cold to return it to liquid.
SHAZAAM! "Build it and they will come."
Meanwhile progress on Dr. Mills' SunCell (tm) reactor (uses Hydrogen in a novel way) is going commercial the next year or two ...
Top notch video and a perfect explanation.
Awesome! Thanks for letting us know.
"Clean energy" cannot stay near the word "coal"... Anyone can say its energy production system is clean than another, but the real pathways to produce really clean energy are very few, and sure coal is not one of these. I appreciate though the great amount of technology and engineering involved in this kind of plant.
Really? The West County Energy Center in Florida was commissioned in 2009. It is larger than any coal-fired plant in the U.S. at 3,750 megawatts. It burns no coal. Instead, it burns natural gas. Unit 3 at the Vogtle nuclear power plant is 96% completed and will be completed soon. It's sister, unit 4 will follow soon after. When all 4 units at Vogtle are running, it will be the most productive power plant in the U.S., producing about 37 Twh of electricity yearly.
This power plant is literally the largest single point source of greenhouse gas emissions in the United States. Like the entirety of the us Industrial complex, this is the single biggest emitter.
And it is contained in a single location. I promise you the EPA knows where it is. Now the millions of cars on the other hand....
Electricity is not the clean energy people are fooled into believing it is. Almost all of it is made from coal fired boilers, that turn turbines, that turn alternators and generators. I will stick to conventional vehicles. They have a much higher range per energy unit, thus, pollute less per energy unit for work done. The lithium mines are real planet killers also. Nothing grows there.

I do love any 3D animation videos on industrial processes, so thanks for that, interesting to see.
However, call me a treehugger if you will, yet it's difficult to shake the feeling that this is an outdated and dirty method of electrical generation.
I'm not saying anything about any other form of generation. I read the comments; I'm not interested in arguing.
I'm just saying I highly highly doubt we will be generating electricity with these methods far into the future.
I'm glad there are other advances in all fields, including fusion.
I mean, the steam generator was the first ever type of generator so yeah, kinda outdated. I believe it still hasn’t reached its full potential

this is a very well put together video!
I know the fly ask can be used for cement but what can the bottom ask be used for? Saw a video about a Canadian coal fired plant where the bottom ask didn't seem to have any use? Anyone know what bottom ask can be used for?
Some folks who live out in the country like to use bottom ash on their driveway. It's a lot better than mud when it rains.
I realize it may be hard for some people to grasp, but the steam temperature is indeed 1000 degrees F and 2400 PSI leaving the superheater to the HP turbine and then sent back to the boiler and reheated to 1000 degrees again and 525 PSI going to the intermediate (IP) turbine. Saturated steam such as 400-600 degrees would do great damage to the turbine.
Why nobody try to put in better use heat instead of those Coling towers. .. maybe greenhouses...
@@maksimmuruev423
Sometimes the steam waste heat is used. Like in New York City's steam heating system. Most of the time though it's easier said than done to figure out a way to efficiently reuse the waste steam heat.
@@maksimmuruev423 What is a green house going to do with 500,000 lbs/hr of steam that is at 2 psia (atmosphere is 14.7 psia)? It is also around 90 F when it enters a condenser. Also need to consider that the condenser is where the vacuum is formed but the collapsing of steam into water. I cant remember the ratio off hand but it is something like 1000:1 in volume. This vacuum helps pull steam through the later stages of the steam turbine and greatly increase the power.
@@maksimmuruev423 You must not have any idea of the magnitude of energy those cooling towers are handling. In NY all the fish in a river were suddenly dying, the investigation found out the water from cooling a coal power plant heated the ENTIRE RIVER enough to kill the fish. Also in Alabama they do not need any more heat for their plants.

@@Jemalacane0 Danke Schön! ~ ^_^
my opinion is that the combination of the movie "China Syndrome" and the coincidental timing of Three Mile Island'a incident contributed greatly to nuclear's resistance. Since then, now 4 decades later, we've (US) lost thousands of nuclear engineers. In my experience, the cost to develop a new nuclear power plant due to regulations just are not worth it. Even converting coal to natural gas is highly cost prohibitive. Cheapest way today to generate 2 Gigawatts is greenfield combined cycle natural gas. Several are being built close to natural gas source in the midwest.

That was VERY interesting and well explained. Can anybody here explain why the water is cooled with water towers? Why wouldn't you resend the hot water back into the boiler with all that residual heat rather than cooling it first? I got lost there.
Not sure, maybe someone who knows can jump in with some answers.
In order to generate steam, it first must be a liquid.
The water that is cooled in the tower is not the water that goes back into the boiler. The water going to the boiler is in a closed loop, and must be condensed through the cycle. The other water used to condense the steam gets hot itself, and must be cooled in the cooling tower so that it can go back and condense more steam.
The core concept is 'hot gas makes wind and moves fan'. I believe the steam must first be cooled because it is the difference in temperature than enables the gas to move at all. If you just had hot gas throughout the system, movement would be zero (or at the very least drastically inefficient). If I'm not mistaken, the larger the delta between cold water/hot steam translates into greater efficiency/less losses since the fluid 'wants' to move more as it expands more dramatically.
I am no expert on the matter, however, and would gladly be corrected by someone who is better educated on the topic.
Power Engineering student here. The water in the cooling towers is a closed loop and does not directly touch the feed water. It removes the heat from the steam leaving the turbine and condenses that steam back into water. The water used for cooling is of very low quality (chlorinated river water greater than 2000 ppm) whereas the feedwater in the boiler is of very high quality (less than 15-20ppm and with many added chemicals to prevent scaling and fouling of the boiler tubes). The temperature of the water entering the cooling tower is roughly 100-105F and leaves at roughly 85F, it enters the condenser at 85F and leaves at roughly 100-105F. The only purpose for the cooling tower is to cool the closed loop cooling water system.
Basically the feedwater and cooling water loops are separate and the water does not mix at all. the cooling water is only used to condense steam in the condenser in order to be able to pump the water (you cant pump steam). an auxiliary cooling water loop is used to cool stuff like lube oil and other equipment that needs water cooling.

Thanks for the informative plant tour. I'd like to know what software is used to create this nice animation?
3D Studio Max - and thanks!
? Why do the water vapor towers not have a turbine/generator at the top of them or throughout it? ( having more surface area will increase the amount of water that gets collected at the bottom, it also creates another point of power generation in the same system. Windmills completely depend on outside air, having it in the vapor tower makes it's run at all times and gets extra power output when the wind blows.) Ps. Lol that's really a question I love to learn so plz explain if you can =) and I know I'm horrible at grammar =)

@@edpvideo Any nuclear is the future. LFTR is just one (very speculative) option.

Use reactors that contain recycled nuclear fuel and breeder reactors that use U-238 as well
@@FowlorTheRooster1990 In the long run yes. But the details aren't worth fussing over. All nuclear is so much better than all fossil that any of them is a worthwhile upgrade.

Well, the generator water is already a closed system. Replace the boilers with two thorium 232 reactors and get rid of all the complicated mess dealing with pollution.

Thanks Andrew
Did you have BDS too? Yoiu know, before Obama.
Wow. Pretty complex.
In response to the last message you cant pump steam. I often wondered this apparent loss of energy. But having worked at 1900 mw power plant for many years this is one of the inefficiency's of the process. Attempts have been made to use this heat source to heat green houses etc. The results are not cost effective. This video tells it like it is.
Thanks for the comment
Actually, district heating is very common in heavily populated areas. So, maybe it is cost effective.
Not enough in the presentation in the transmission section. I always assumed 25kv or so from the generator output was put into a step transformer as they said, but wanted to know more, as I'd heard that the high 400kv voltage in the step up transformer went through a spark gap. Then, it goes on a slasher for the 50 or 60 timing. It's transmitted out as a DC pulse, supposedly at high frequency like 55khz, with a 50 or 60 slash. Gerald Morin was explaining in this in his videos. How does a steam turbine maintain the 'exact' 3000 or 3600 rpm to maintain the 50 or 60 hz output? Also, the power generator itself couldn't produce enough power, unless it runs faster, then the power is converted later in the line. I'd like to know more about how the pole transformers work. They receive the 'transmitted' line, no neutral, which is grounded to earth at each end, the live wire terminated in the can itself. Also, burning coal is very inefficient. Peter Davey invented a device that heated water up immediately, just using acoustic resonant sound waves. Also water could be used, by splitting it into hydrogen from oxygen, then using the hydrogen gas to heat the water. The burning temperature of the hydrogen would need to be lowered down, so the gas doesn't burn through anything. It's impossible to transmit.. current over the grid, so the current along with the 120 or 240 50/60hz is done from the pole transformer itself.
Thanks for the detailed comments. Wish we could have gone into that level of detail, but it was just an overview.
Once the generator synchronizes to the grid the frequency of the grid keeps it locked in. These turbines also have governors to maintain the speed. Now the watts are controlled by the turbine once the generator comes on line. Watched generators go on line many times in my career. Always fascinating to watch.
Say ahhh there "A", you kinda wrote a 'book' on us there ... look for a video on "power transmission" first and then "power distribution" next.
awesome video, great description of the process. obviously a huge amount of engineering went into this.
We need to replace all coal plants with nuclear. Nuclear can do the same baseload job without any CO2 or particulate emissions.
Combustion engines use for mining and transporting uranium emits greenhouse gases
We can't avoid CO2 completely
but then where are we gonna get drywall??
Easy to say, but the residues of nuclear can be equally or more dangerous than the CO2.
@@odongemma4170 Unless you electrify transportation and even find a solution for more effective mining. Today's problems aren't necessarily those of tomorrow.
@@antonellaromero_upc1564 Well 95% of nuclear waste can be recycled and the total amount of heavy toxic nuclear waste dramatically decreased. We also need to compare the volume of waste: the generation of electricity from a typical 1,000-megawatt nuclear power station, which would supply the needs of more than a million people, produces only three cubic meters of vitrified high-level waste per year, if the used fuel is recycled; the volume of CO2 from an equivalent coal power plant is, as you can imagine, significantly higher.
Better understanding 👍
Cool, thanks
Is the limit of stepping up only 20 times ? Is it possible to steeping up more than 20 times by step up transformers ? Or it is limited ?
you can step up as much as you want, the thing that you need to care of is that with higher voltage the electrons can jump further, so you'll need higher electric cables, bigger transformers, bigger circuit breakers, etc... this might not be worth
here you can see a 1.1MV transformer capable of transmitting up to 12GW th-cam.com/video/0pGH1B863oI/w-d-xo.html&ab_channel=EngineeringWorld
Do they use light oil to ignite the coal when putting a coal mill in service to the boiler ???
I believe they use temporary generators to put a plant into service. Someone can correct me if I'm wrong.
@@edpvideo
They use natural gas or oil ignition torches to ignite the coal-air mix, the torches in turn use spark igniters to get started. They sometimes use the ignition torches at low load to make sure the coal still ignites reliably.
@@gregorymalchuk272 Thanks for clearing this up.
Yes, They use light oil like a diesel fuel to get the boilers started until its heated enough for the coal to be used. Especially if it’s been shut down for service.

Sweet Powerplant Alabama
Ahh, so that raises the question: Since you appear to use electricity just to get things moving and grinding before you can boil and generate, how do you boot a place like this up? I mean... if it somehow lost the grid all around, or if it were the only one on a specific grid. Does it have diesel generators to give it its boot-up power for that?
if you had to, you could use force multiplication (gears and lever arms) and use a few humans to crush enough coal for the furnace to fire for 20-40 minuets, which would be enough to restart and accelerate the crushers to operation speeds.
In some power stations, gas turbines similar to a jet engine but designed for power generation may be used.
Small plants have diesel back up. Some will use a simple cycle combustion turbine, jet engine, some will use a smaller auxiliary boiler as a small one is easier to get going and use it to start the mains, and others simply go offline and stay that way. Many plants do require cranking power. In the restoration plans a transmission operator will have designated certain plants (or units in a given plant) to be "black start". Meaning they can start with no external power source. They will come up, or designed to remain online through special protection schemes, and they will work to get a power path to the other plants that are able to come up quickly. This is all planned and practice. I have done simulations myself.
This is what's referred to as a "base load" power generation plant. It runs 24-7-365. Only portions of this plant are shut down for maintenance.
Muchas gracias por compartir 😊
It's nice to actually watch one of these when it's _fact based_ and created by the people who are actually running the process. It gives me something to reference when I run across other videos that are full of detritus and guessing, and where people in the comment section are losing their minds about all the "pollution" coming out of the stacks, when in fact, it's *steam* that they are seeing. People can be such IDIOTS...
Thanks for the positive review. Glad you appreciated the content! Please share this video so others can find it. Thanks again.
Lol. I won't comment on the idiots part, but what I will tell you is that you are delusional if you think that's steam coming out from the stack. Steam is only coming out of the cooling tower... what you see in the stack includes a bunch of other harmful and hazardous gasses such as the remaining 5% SO3, a ton of SO2 which the limestone doesn't scrub, plus CO and other compounds. I totally understand that this is needed for us to survive, but we need to start adopting the alternatives fast rather than sticking with this old, out-dated, and pollution intensive power generation.
Fascinating.
Great to see the generation of reliable electricity 24/7 regardless of the weather.
Yes, with the risk of a meltdown.
Where I reside, enormous coal trains come into a station that coal fires enormous furnace that boil water into steam. The steam turns lots of turbines that turn enormous alternators. The power is then distributed to station that step down the voltage.
Really? Kinda exactly like in this video then right?
@@flaplaya A lot like the video except I live in a cold climate. Birds love to live close to the steam stacks to keep warm.

Yes, it refers to the effects that happen when energy is created if you burn something you have smoke and ash to deal with nuclear you have waste products and so on.
But you can get clean energy Boil water in a vacuum convert the heat energy to kinetic and electrical with a turbine the water will condense after that maintaining the vacuum.

Coal is the future in the world with C02 free power plants
Eddy De Paepe sorry boss but natural gas is a cheaper, cleaner, requires less maintenance, staff and can achieve a lower emissions at a greater efficiency. Natural gas can also be regulated to meet demand where as a coal fired plant has to produce a base load even at times of lowered demand. Carbon capture also reduces a coals units efficiency by about 1/3 as the sequestration and compression stage of the C02 collection is extremely power hungry. When government coal subsidies eventually come to an end coal plants will cease to be sustainable.
Nuclear when done correctly *cough cough Chernobyl* is very clean very efficient and safe
Yeah a single pellet of uranium has the energy potential of about 1 ton of coal
Nuclear is the future.
Chernobyl station by itself wasn't so bad after all units 1,2,3 worked just fine. The main problem was in assholes who controlled the reactor. Actually, Fukushima shows the same issue... operators don't know how exactly work everything inside which is crucial for emergency control. And all of this besides just engineering problems which of course always are lurking somewhere.
Wish we would move towards nuclear instead of renewables or fossil fuels.
then where would the by-products for industry come from ?
whats wrong with renewable powerplants?
I liked it. We still need the coal people, they're doing a lot of modernization processes like the many scrubbing/cleaning stages.

Why do you have to cool the water. It takes a lot more energy re-heating it from cold, instead of just topping it up with a little heat from the boiler?
Because water expands 1600x when converted from a liquid to a gas (steam). In a contained space that equals 1600x the pressure. It's that pressure increase that moves the turbine blades, not the fact that it is steam. Once that pressure is released/expended into the turbine, it is just steam, not high pressure steam. It must be cooled back into liquid form in order to reduce it back to it's 1600 times smaller liquid form, so that you can reuse the same clean/purified water in the closed loop system. And keep in mind that you're cooling it just enough to liquefy it..
@@MatHelm The pressure increase doesn't come form phase transition. It is set by the pump that compresses saturated water coming from the condenser.
You can't just dump boiling water into the river, it would do greate damage to the plants and animals.. Anyway, the boiler water has additives to prevent corrosion of the pipes and turbines. Can't dump that into the river either. That is why they use a closed loop system and use evaporative cooling.
Good informative video though you have mentioned the temperature is 1000 degree in fact it can't exceed 550 c .
Its a video about a US powerplant, 1000 degrees in freedom units is about 537°c
