- A power plant’s plans to cut up and recycle a giant steam turbine is a rare opportunity to take a peek into the clever engineering inside: from the casing to the boiler to the fan blades.
From the Series: Inside Mighty Machines: Power Plant bit.ly/2XQnn1t
I'm retired now, but I worked as a boilermaker as a young man. And I spent many hours working in all types of power generation facilities. Walking across the turbine deck at any power plant gives you the realization of how impressive these machines are.
I have done turbine millwright work for a few years now, and just worked at the dry fork power plants first major outage. We completely dismantled, pulled precision measurements, cleaned and repaired anything out of tolerance. I have known many Boilermakers but never really appreciated them till this job. I walked through the Boilermakers job with my road neighbor after meeting him a few days prior. He showed me what you guys do on a major outage and revamp. I was impressed. I thought millwrights were cool until i saw the intricacy of a boiler job.
@@hadleytorres8171 I’m a chiller mechanic and I’ve done service and rebuild work in many of the power plants here in the south. What always amazes me is after you guys overhaul a turbine, it’s so clean when your gone. You guys make it where the floors could be eaten off of. It’s very humbling to me being in those plants. Just thinking of all the great minds behind the turbines and all the physical work that goes into making electricity.
I too used to work in a power plant and some people don’t realize that after the steam passes through the turbines what happens ? It gets condensed back to water creating large vacuum and the vacuum also in a way helps draw in the steam therefore turning the turbine. Pretty cool mechanical design
I always thought they heated it up all the way to dry steam and blasted the turbines that way, like a gas turbine. If only to prevent rust.
Rather than wet steam like you explained.
Interesting.
@@davecrupel2817 Anytime steam is heated over the saturation temp it is considered dry steam or superheated. Most all steam turbines run on superheated or dry steam.
@@josephkordinak1591but at some point it become liquid if the temperature or pressure drops as it goes through the turbine?
@@forloop7713 you have problems if it becomes liquid in the turbine. The exhaust of the turbine is dumped into a condenser which is under a vacuum and has tubes filled with cooling water which condenses the steam back into water to get pumped back into the boiler.
Hey steam turbines! Big fan!
Lmao how long have you been waiting to use that one?
@@jacobmortimore lol, I've seen you somewhere 😂
Smart!
How do you pronounce the following words?
1. fine
2. mine
3. line
4. nine
5. pine
6. sine
7. tine
8. vine
9. wine
How do you pronounce turbine? NOT TURBAN.
Ascetic not in this industry. We pronounce it as he said.
Eric x yeah thats define because of the industry. I’m over in europe and they pronounce the word differently only for this application. Otherwise people would get confused as many things are called turbines but only one thing is called a turban.
The man with the yellow plastic turban was taught to pronounce it that way. How does one pronounce Brexit now? Increasingly it seems Brexshit is appropriate.
So you're saying that eng-GAN is wrong? You say en-GINE?
@ascetic ahem, "determine." ::mic drop::
In California the geniuses on the coastal commission decided that the coastal generating stations should no longer use seawater to condense steam. This was a multi-trillion-dollar game losing decision that met no resistance. They actually have air cooled condensers at the beach with cool Pacific water right there. Californians pay double the National average $/kWh. They threw away perfectly good steam turbines with low-Nox burners on the boilers. They just pass along the costs to the consumer. It is ridiculous.
Romans ground corn in 70 bc? Where did they get the corn?
That's a significant blunder. Corn (or maize) wasn't cultivated in Europe until the 16th century. It must have been wheat, barley, or some other type of grain.
@@artmoss6889
The historical use of the word "corn" is just a generic word for "grain". In this context, "maize" was the historical word for New World corn.
THIS!
thank you for noticing that too
Minong Maniac same question...
@@gregorymalchuk272 True. I've come across the use of "corn" in English Medieval and Renaissance literature as a generic term for grain, and it may still be used that way today in Europe, but I just don't know. In the U.S., however, "corn" has a narrow meaning, and since the video was produced by an American museum, the narrator is American, and the intended original audience was probably American, using "corn" in this instance gives an American listener the wrong impression about what kind of grain was being milled. This issue is important to me for reasons too boring to go into here.
This place used to be down the road from me in Salisbury, NC.
0:51 They are really cleaver piece of engineering
*le me, mechanical engineer:- It is . IT IS
Have spent many hours doing refits in Ameren U.E's plants in Eastern Missouri.
How could the romans have used this principle to grind corn when corn was in the americans and not shared with europe until long after they were gone? Sure, they did wheat and barley, but the video says corn.
ya this is interesting! i wasn't aware of this, but apparently in British English, the word "corn" refers to "wheat"
and in American English, the word "corn" refers to "maize"
i was aware there are dozens maybe hundreds of differences between British and American english, but i never ever would have guessed that Britons refer to wheat as corn haha... that was a shocker for real!
Another great video from Smithsonian thank you for this ur fan Otis here

Steam turbines are perfectly good power generators. (When they dont rust)
How do you think nuclear plant create electricity? :P
Nuclear plants use steam turbines, too. In them the steam mostly exists in the wet region. Rust and other corrosion effects can be mitigated by material choices and keeping the steam clean.
Fermi 2 in Michigan is a nuclear power plant that boils the water from a great lake to make steam to power turbines.
I wonder how much power one little turbine vane produces? Will it power a space heater, or just a light bulb?
You could probs do the maths, take a look at the total number of vanes, divide them by the amount of KWH produced, factor in stepping down etc and boom xD
Here in southern Nevada, we use hydro-electric power from the Colorado river by way of
Boulder dam. With NO pollution! None! Nada! Zero! Zilch!
Yeah, with dams all the environmental damage is done up front.
Lets not forget the river that was dammed up destroying the natural ecosystem in the process along with the 96 people killed building it and that doesn't include those that died latter on from silicosis and emphysema from the rock dust building the bypass tunnels.
@@vettekid3326
Because coal power and black lung disease is so much better?
@@richarddarlington1139 I think he forgets what burning coal did to London. Hydro electricity is definitely the lesser of 2 evils.
@@MissKristiLee
Nah. Some people just like to argue because they have nothing better to do.
Did you know that Las Vegas has protected wetlands? Yep. A sanctuary for many species of fowl right here in the high desert.
Not to mention, building the dam created a quaint little town now known as Boulder City. Unlike these useless wars, those men did not die in vain.
And the Vegas Valley skies are the most beautiful azure blue.
Be well, Kristina.
It was very helpful because I don’t know really much.
Thank you! TERBIN.
Many Railroads should have used these with electric locomotives!
There was one such machine built. Too complicated.
I wish more of the turbine was shown, just a snippet.
Do you mean turban? Or turbine...
@@JeremyHobbs I fixed it but was making joke. For my friends in India.
Ah yes I love TURBANS!!
Before I saw the guy I thought Steve-O is doing documentaries now?
Do these have stator blades like jet engines?
Yep......one stator stage for each rotor stage.
I can assure you the Romans had zero corn in 70BCE.
I can assure you that the British-English term 'corn' refers to any form of grain.
It was very helpful😍
1:15 ain’t no way. Corn wasn’t naturally found in Europe or any other part of the old world.
Absolutely way. 'Corn' is the British-English term for any type of grain.
Everywhere in the industry it's pronounced "turban". If you're around industry people and pronounce it "tur-byne" they're going to look at you funny. Maybe it's not technically correct, but that's how it's said.
Not in the UK where the turBINE was invented by Charles Parsons at Newcastle upon Tyne.
Unless you're from Canada.
Steam turbans have been used ever since Charles parsens first used his first ever turban powered boat, the Turbinia 🙂
It IS technically correct. They're called "homonyms".
all born equal, unless you're Canadian, then halfway through decay like Uranium.
Couldn't continue to watch after hearing of so many turbans,
Triggered, eh?
Ancient thing,
(Pressure)lol
This place looks like the Pokémon hymn for the steel type gym leader.
I came here because I had a dream that a powerplant in England exploded and blew up England
*The Power of steam is still useful*
Despite electricity being the most energy used
Steam is still used in all pwer plants except solar, geothermal, and hydroelectric, to convert heat into mechanical energy used to spin generators that provide said electricity
Think about it.... even a nuclear power plant produces steam.... that steam is used to produce electricity
Wait, what? How did Romans get corn in 70 BC?
Didnt corn come from america?
Steam Turban
Oh, so that's what it looks like if you don't drop it.
they really sold a machine for $20000 when it could make $72000000 per year mining bitcoin at todays rate
1:15 Romans used this technique to grind what?? Corn?? A seed that arrived to Europe from America in XVII century?
'Corn' is the British term for any kind of grain.
These are outdated. The new ones are a lot smaller and make twice as much power. I am actually working on 3 of them right now
I don't think steam turbines are getting much smaller. There are fundamental dimensional constraints involved in keeping the steam velocity subsonic that prevent making turbines smaller for a given power.
@@gregorymalchuk272
Yep.. the current ones, like in nuclear plants, are much larger than those. The rotors can be ~30 feet across and weigh ~300,000 lbs
"Turban Blades"
20k for that? What a joke lol
Turbans. 😂😂😂
Where are you getting $2 a pound for metal?
maby its stainles steel// some spacial alloy
Lots of nickel in turbine alloys
@@thomasjefferson5727
Yes.. could be inconel or other expensive alloy
😮😮
stop calling it tur-bin
Giving a measurement of power without time isn't useful, 80k kwh, 80k kwm????
@Jordan Why do you have to be such a spiteful little grinch of a human being? I started reading your comment like, oh, science, cool, and ended with if you got corona it would be karma.
@Jordan Following my previous comment on your grinchy nature, the video actually states measurement of energy without a timeframe as reference.
It's generation capacity, very useful. 80kw for as long as you'd like. Until the unit fails or drops load.
The standard for time in the electrical energy industry is hours. So that turbine make 80 MWH. Most people just drop the H.
That's actually a small unit
Yes.. I worked on the turbine deck for a couple of nuclear outages. Those are pretty much tiny compared to the big boys.. weighing about 300,000 lbs for just the rotor.
Very small by today's standards. Nobody even uses KW to describe one. Its MW.
A steam turban?
Yes, high pressure turbans and low pressure turbans. Great engineering feats 🤟
Maybe check with google before wrongly pronouncing the topic of a video, throughout the whole video.
Should probably check with google yourself before posting this comment.
So I went and looked it up and since he's clearly speaking American English his pronouncement is actually correct. In England they pronounce it with the hard "I" but in the states it sounds like the thing sihks and hindus have on their heads. Both are technically correct, the best kind of correct
Isn't a "Turban" a form of head wear?? 🙄 For the record it's also pronounced "tur-bine" in Canada 🍁
ter-bin
American English does it wrong again! Haha
Steam turban? What's a steam turban? Sounds painful
It makes your hair fluffy....
0:17, dude, it's tur-bain not tur-bin
more like tur-byne.
@@Heavygusto yeah that's what I was trying to say
It's pronounced "turban" in the industry. Maybe not technically correct, but everyone that works around them pronounces it that way. So in that respect, the guy in the video is pronouncing it correctly.
👍👍👍👍👍👍...🇧🇩🇧🇩🇧🇩🇧🇩
Turban? Who’s the actual Engineer?
I am, and that's how it's pronounced in the US.
Turbans?
Yes. Like engan. It's an industry thing.
Yep. That's just how it's said. If you say "tur-byne" around industry people you'll probably get some funny looks
🤘🤘
Tell me you know nothing about how these work without telling me.
I wish people could pronounce turbine properly :/
tur-bine say it with me my man a "turbin" is not s thing
"Turbin" ! Really?Coming from The Smithsonian channel
Ask anybody in the US turbomachinery industry, and that's how they pronounce it.
Please use Kilograms instead of pounds. Kilograms not Pounds. This is starting to be almost comic. The scientific world does not use the Anglo system, they use the metric system. Why you may ask, because 1000 grams makes one kilogram, 1000 kilograms makes one tonne. But no, let's use pounds and Stones instead. Keep up! And while we are at it lets use foot pounds/torque. It's not that the rest of the world have a perfectly good measure, Nm. Stop this madness.
This is an American show, on an American RUclips channel, on an American website, on the American made internet. So we get to use the imperial system all we want.
Jack , and yet you keep crashing satellites (many used for internet) because you don’t use the metric system.
There are two types of countries on earth. Those who went to the moon, and those who use the metric system.
The metric system didn't put a man on the moon.
I'm from Canada and regularly turn shows off that don't have imperial units or at least imperial equivalents. You've got a calculator, use it. 454g = 1lb. Have fun with the math.
A TURBAN is what you wear a TURBINE is what you use to make power
No, in a turbine you convert energy from speed (in the flow), heat and pressure into rotational speed of the rotor.
