Power For 300,000 people! The 60 Ton Industrial Steam Turbine!

Let's get nerdy about these CRAZY machines that weigh TONS and produce enough power for 300,000 humans. Siemens let us come by their Gorlitz facility and take a tour of their Industrial Steam Turbine assembly shop. We of course filmed the tour, and I hope you enjoy it.

Incredible! This reminds me of a how it's made episode 😊

[@Telephonebill51]

Except that there was nothing whatsoever about how it was made.

[@georgeliu7575]

I worked in an industrial steam turbine factory of Siemens partner in China for 12 years. I like the art-of-the-state Siemens- designed steam turbine products so much. The job experience there shaped me a lot and benefited my later job. Simens is great!

[@deadsi]

I too love semens

[@knutholt3486]

What impresses me is not the size of the thing. What is impressive is that it actually is small compared to the work it does.

[@jeanwycliffeahorukomeye7479]

This is deep 😉 im watching this video in loop thinking visiting the Siemens factory myself. Any references for a tour ? Dhr Detlef Haje?

[@brianthesnail3815]

The biggest heavy frame industrial gas turbines that Siemens come in at over 500 MW and weight over 500 tonnes. The waste heat coming out the back of those goes through a heat recovery steam generator that creates steam which is then put through one of the steam turbines in this video. The so called combined cycle gas turbine power plant is a gas turbine, a heat recovery steam generator and a steam turbine running in combination and have very high heat efficiencies.

[@AluminumOxide]

What makes it more cool is the fact that the central shaft is made from a 100 tonne single piece of forged steel that was once red hot and squeezed in a hydraulic press into shape.

[@JohnOCFII]

Very cool, Joel. The size and precision are amazing. Thanks for sharing with us.

[@bradpetersen92126]

The Navy Destroyers I served on had the high-pressure and low-pressure steam turbines separate with the main steam entering in at 1200 psi at 975°F, exhausting out through a very large crossover pipe to the low-pressure turbine, then out the bottom to the saltwater condenser to be returned to water, and continue the cycle. Incredible machines….

[@michaelc8264]

Incredibly cool stuff! Glad you could share this with us!!!

[@siyu313]

That right there is a guy who enjoys his job! Im sure his kids are mini turbine engineers from all the free knowledge.

[@TheMidnightSmith]

DONT YOU DO THAT TO ME! DONT YOU END ON A CLIFFHANGER!!! For real though, I work with ones half this size daily, had no idea the clearance was so tiny! Some serious precision there!

[@TechnicallyNerdy]

Crazy precision, and the 3d printing story continues on the main channel tomorrow.

[@NoNonsenseKnowHow]

[@dalsenov]

[@izalman]

Those rotors are small... I worked on machinery that overhauls rotors that weigh 250tons.. including lifting them from horizontal to vertical to dismantle / re assemble them and true up all the mating surfaces to minimise supersonic speed steam disruption.

[@jacoblocklear6809]

What size was the lathe that trued it up

[@ShainAndrews]

Never would have expected 160 bar. Clearance between the stator and rotor is tight, even for the smaller sections. I have a feeling there is a specific start procedure that allows thermal normalization prior to rotation.

[@paulcurrie7828]

Warming of the case and stretch out of the turbine rotor using steam for heat. Also the while this is happening the rotor is on barring gear turning very slow like 1 rpm to allow for the rotor sag between bearings to straighten out

[@ShainAndrews]

@@paulcurrie7828 Yup that was roughly what I estimated it would take.

[@scottstensland]

the Siemens rep should have explained each rotating blade sliver is sandwiched between a static blade unit ... these turbines have dozens of these pairs ... the steam escapes through each sliver ... the rotating section forces steam up followed by its static blade forcing steam direction down ... this tension powers the rotation

[@Matas3DCreations]

thats so cool ! im looking into solar panels to power my 3d printers in my workshop gotta figure out the numbers first tho but now i really want to try it for the free energy every time i get a new 3d printer i notice my bill go up and up lol

[@chuckaddison5134]

Are the blades replaceable, as they are in jet engine turbines? Also! What is the change in blade angle and spacing (rotor and stator) from beginning to end?

[@pycharm708]

I m in love with this stuff

[@RagionamentiFinanziari]

Very impressive

[@gizmobowen]

As a fellow Washingtonian the first thing I thought about when you said you were going to talk to Detlef was the famous UW basketball player, Detlef Schrempf. Maybe I'm the only one though....?

[@jedwards1211]

0.4mm between the stator and the rotor on the smallest end 🤯

[@yuvrajram798]

So incredible information

[@TechnicallyNerdy]

Glad you think so!

[@Phil-D83]

Supercritical steam is awesome

[@harlockmbb]

KZbin recomended this video after the engineerguy video about turbine invention. :D

[@komolkovathana8568]

I wonder, these main propulsion cannot be run by WASTE HEAT of lower than 250 °C of low pressure steam but they(turbine) need at least Main Source of 350°C, medium to high pressure steam to provide the power for 100,000- 300,000 people (250 MW).

[@komolkovathana8568]

4:44 And he said 560°C @ 16 MPa (160 barg), that cannot be waste heat.?

[@discoverymoi]

Are these the same ones used in nuclear reactors?

[@stevedoe1630]

Nerd-up…. These turbines are so heavy that they need to be continuously spun, even slowly, when warm. The rotor is more malleable at higher temperatures, and is susceptible to imbalances.

[@CreativeSteve69]

I always enjoy watching your videos. I usually don't do this but I came as fast as a steam turbine n was first. :)

[@moeniebdavids3033]

Does anyone perhaps know where i can guy miniature turbine models?

[@Andreschannel_SA]

60-Ton turbin. Wow.

[@geofferyromany4634]

[@jvd0701]

[@locklear308]

THIS is how you make power.

[@gepeszifju]

How does it possible expanding steam lower than the environmental pressure (vacuum)?

[@jonathanparone733]

How much is the cost to buit that king of power plant

[@CantGetEnoughBach]

Wow!! when I was a college freshman I worked in the heating plant for the whole campus. We had a steam turbine-powered generator that could produce 500 KW as a backup power supply. It was far from the technology you just showed us. The patents were from 1905 or so. Could a modern turbine design efficiently power a locomotive? Much heat is wasted in a traditional steam locomotive because the spent steam is not recirculated as feedwater, which makes a lot of maintenance problems for boilers because of accumulating scale. But with modern design techniques and turbine-electric drives what level of efficiency could be achieved?

[@FUZxxl]

Main problem with a closed steam circuit in a locomotive is condensing the steam.

[@jasonlivi3039]

It's great we can produce mechanical energy at such a low cost it would be nice if the consumers could feel that more. Look how much electric one turbine can make for years with little maintanance.

[@l0I0I0I0]

Do they have a hydrogen steam energy yet? More important, where can we learn how to repair and operate one?

[@d.cypher2920]

*"1 megawatt is the equivalent of 10 car engines."* that's actually very helpful for my mind to understand the equivalent power ratio and output. great videos. *kids, listen...learn science, technology, engineering and mathematics.* you'll have nice things, and that affords a more comfortable lifestyle. (And a better quality wife or husband. it's simple, not complicated.) ☀️😎🇺🇸☀️

[@vistakay]

1 MW is 1340 HP so 250 MW would be 335,000 HP 🤯

[@wilfridseme4433]

Is there an advantage to not having compound turbines?

2:41 Let's see...500 m/s = 0.5 km/s = 1800 km/hr = 1125 miles/hr. And presumably he means at the outer edge of the largest blade. By the looks of it, it's about twice as high as a person, so say 4m diameter or 12m circumference. So at 500 m/s that's about 42 revolutions/s = 2520 rpm. Not all that much, although I suppose it is a lot for such a large part operating a quite a high temperature.

[@SDCustoms]

Not very much rotational speed, but think about the massive amount of torque when it's cranking out 250MW.

[@bapimurmu7738]

@@SDCustoms what???? Not very much rotational speed???? Man,almost every thermal power plant turbine runs at the speed of 3000 rpm.... And that's a lot... Believe me... And for that huge rotor and blade assembly together... It's a lot.... Think about the perspective... Small things can really rotate very fast... But for that huge assembly, it's fast... So fast
