Steam turbines lie at the heart of these power plants. They convert thermal energy in the steam to mechanical energy. This video will explain the inner workings of the steam turbines and why they are constructed the way they are in a step by step logical manner.

There is an important error in this video. 2:50 shows the entire low pressure turbine. But the animation is missing the first row of turbine guide vanes. In turbines you always need a stator in front of the rotor to give angular momentum to the flowing gas. The turbine blades will use the energy of this angular momentum and convert it to power according to eulers law. If the gas goes through the first turbine blade row withot that momentum, the first row cannot generate any power.

I've always thought that the blades positioned opposite of the other moves in the other direction.

In the "Boiler, How it works" video you said that presussure would ideally remain the same but it increases a bit because of friction and other stuff... But in this video you are saying that pressure is source of energy and I understand that pressure is desired....

Hello Sir! 1.How do we decide whether we should be using impulse turbine or reaction turbine?2. The fixed blades shown in this video are attached to what?3. Do we attach nozzles in reaction turbines?? Thanks in advance sir!!!!!

Flow governor (control valve ) functioning to adjust steam flow in to maintain turbine rotation remain constant .( refer to standard frequency of output).
torque395 (10 months ago)
So a steam turbine doesn't use steam exclusively? Its more like a superheated water turbine? (which means that there's got to be pressure also to increase the boiling point)

wich 3D design programs do you use to model mechanical parts?
Lodewijk Vrije (10 months ago)
i think our best bet for renewable energy will be Fusion, you take a metal of pretty much any kind turn it into a liquid as hot as you can get it. and then you start to compress it, until it gets real real hot (millions of degrees C) it is now called plasma (we can make this it is possible, we are just struggling suspending the plasma so that it doesn't burn down the power plant) the best thing about Fusion is is that if you put in 1, you get 100 back (its insanely efficient) and because it works on the principal of turning metals into plasma, we already have enough fuel stored up for decades, in the form of nuclear power plant waste. of course this still requires a steam generator to convert the heat into electricity.plasma just burn so hot, that you could probably run a multitude of steam generators of one plasma source. vacuum compressing metal isn't the only way of creating plasma btw, another way which is being researched is with high powered lasers, the downside of course being that you need a small power plant to create your plasma with the type of lasers involved.
Lodewijk Vrije (10 months ago)
if you are interested in making plasma or what it looks like, you can make a very basic form of plasma right at home! all though i do not recommend doing it inside, and i do recommend keeping a save distance from your little project. you will need a microwave of at least 750 watts, 3 metal bottle caps of the same size, and a piece of wood, like a match stick, or kebab skewer. and a normal tall drinking class. and a small piece of silly putty, or similar substance put the microwave outside, and put the 3 bottle caps in it in a triangle formation. put the silly putty in the middle of the triangle, and stick the match or skewer in it sticking straight up. the glass should now be able to stand upside down on the 3 bottle caps, with the match stick or skewer inside the glass. this is what you want, take the glass out, set your microwave in normal microwaving mode. and set the timer for 2 minutes. now light the match stick or kebab skewer, gently place the glass over the match and standing on the 3 bottle caps. close the door, and take distance. almost instantly green, and red lightning bolts will surge on the inside of the glass, and it makes a Wierd un describable noise too. you have now created a rudimentary form of plasma. now wait out the 2 minutes from a save distance, when you come back you see just how hot that plasma has burned, as in 2 minutes it should reach temperatures between the 1400-1500 degree C mark, that is well within the melting point of glass, which you will see. if your microwave survives 2 minutes that is. if your microwave survived i would let it sit for an hour or more, as glass cools down relatively slowly. but then when you take the glass out, and feel the surface of it. you can see it had started to melt, sometimes it gets even hot enough to make drips of glass that cooled down again while they were running down the glass.

Sam (10 months ago)
@Learn Engineering , I have a question I haven't been able to find the answer to in my books or online. -I noticed in the video, during the explanation of steam via 2nd law of thermodynamics, the narrator mentioned how the higher temperature of the steam leads to *"higher efficiency of the power plant"* (with respect to the turbines' temperature limit). -My question is: Does that statement of 'efficiency' take into account the amount of coal (or other fuel source) added to increase the temperature vs the power output of the generator? OR is it Only in regards to the temperature of the steam vs power output (not taking account of heat source)? Great video nonetheless! -Sam
