Excellent presentation - very informative. Takes be back to my college days - blackboard and chalk - can't beat Old School. Your engine series is a pleasure to watch. Cheers Craig.
Good for all of those boiler mechanics that wonder why the boiler uses hundreds of gallons a day. As an old Serviceman I knew this for many decades but never had such a good explanation although you can improve on it a bit, lol. Good job.
The phases are also a function of pressure. 720 degrees at a particular pressure may be super heated, but at another pressure it won't be. The PT (pressure-temperature) diagram has this relationship.
great info , these days they dont use expansion valves as much as they use to now they use a capillary tube , its way easier then expansion valve , expansion valves can take a long time to get working , they have to be set just right
Thanks for this, it told me a lot on something I need to know. I haven't looked at your other videos, but could you do something to help me calculate the amount of steam/water for a given output of steam. thanks again
Thanks for watching! I would need more information on the system you are describing to give any kind of good feedback. Is this a steam engine system? What pressures/temperatures? Is it a closed or open system?
Let me explain my problem or lack of knowledge. Lets say I want to build a boiler big enough to handle a steam engine with a 3" bore and 3" stroke, Its going to run at 360 rpm at about 100 psi. (I think anyways)Questions (consider them all a "how do I calculate" question): So, if I have a cubic foot of water, how much steam will that generate at 100psi or 200psi. or, maybe I just need to know how to calculate HP for a boiler. I'm thinking off grid power, and I think I need about 7500watts to run a typical house.I think (don't know) I need a better understanding of the steam tables.
So in order to answer this question fully, I would need to do a lot of math and I just am not motivated enough to dig into it for a TH-cam comment. A very helpful resource for quick and dirty empirical formulas is the book "Steam Engine, design and mechanism." It is an old steam engine engineering book written almost 100 years ago and it has all kinds of equations to calculate things similar to what you are asking. Anything more exact will require an in-depth thermodynamic analysis.
Taking the density of water to be 1 g/cm³, you need 1 L of water to produce 1 kg of steam (in actual fact, you need a bit more, since water is not quite that dense). To make 1 ton of steam, assuming you use a metric ton, you need 1,000 L of water. Capacity depends on boiler package system.
I would like to point out that steam can exist “dry” at one bar on the steam saturation curve, it can also exist with a higher moisture content (wet steam) The term dry steam is used when the steam has gone through a separator or through pressure reduction. Superheat steam is neither dry nor wet. It is it’s own property.
@@MR-nl8xr 1kg of steam = 1kg of water. Steam at 95% dryness, will have a slightly more water, so for “1kg” of steam you will have 1.05kg of water. This only really becomes an issue with sterilisation processes, where we want as dry steam as possible without being superheat, and is also an issue with direct steam injection to processes like feedmills where higher water content can clog the conditioner up. This generally won’t be an issue if the steam lines have been installed correctly to the process with correct steam trapping, and then the correct steam conditioning to the control station for the process. Both Spirax Sarco’s website and TLV’s website are really good. If your in Australia I can help you through my own business.
@@reubs91 I will have to marinate on your awesome reply, so i can understand better. I will check out those websites👍. I am not. One Day I hope to make it that far across the planet.
@@MR-nl8xr no worries. I didn’t mention in my reply that a well designed system with insulation will be running at approx 98% dryness. You have continual heat loss through the pipe work itself that creates that condensate that needs to be drained. One issue I do see a lot that will get everyone is boiler carry over. This is when the steam demand outstrips the steam supply, this can happen over a few seconds or over longer periods of time. This is probably the biggest causes of steam issues and maintenance, boiler water is very high in TDS and carries through water chemicals that can eventually turns into a sludge and even granulates. To overcome this you need to ensure your boiler is capable of supply the correct quantity of steam. Some processes have steam on/off over a few seconds so the demand can be huge over a very short period of time. This means you might need a boiler that’s quite large compared to the process. Another way around this is a accumulator but are often overused and that’s another story. I’m on LinkedIn Reuben Allen - Steam Energy WA
A little correction needed,no offence ,refrigerant boils in the evaporator,boiling is cooling. It condenses ,giving off its heat,in the condenser ,not the atmosphere,big fines!
you seem to have missed out dry saturated which is not superheated...it is exactly what it say on the tin, dry saturated. Superheated steam behaves as a gas. Dry saturated does not.
You have good content but you should really outline or write out what you want to say before saying and filming it. Maybe even storyboard it so that you're not winging it as you go along. Otherwise, you lose your viewers and make the video a lot longer than it needs to be.
Lol; when we wait, the movement workshop Lol;. , I'll add "efficiency form" at the end of the video more used for heating or cooling transfer devices, not for engines- producing power, because in the case of a steam engine, this formula only shows how well is heat insulated engine, Dry/Super heated Steam and better because it contains more heat, and his loss scanty in percentage because of not perfect heat insulation, not so critical.... in the case engines- producing power, used correlation the ratio between power and amount of fuels(heat), and where more power to the same amount of heat is the better in the case of a steam engine used correlation the ratio between power and amount of heat(fuels) used in the boiler to have Wet Steam or. Dry/Super heated Steam, and how much "mechanical power" we will have in each case
Around a year back I wanted to build a steam engine to use in SHTF situation. I find all kinds of build your own here on yt, but none of it was really making any sense. With watching this video now, I think that I was right, it was not making sense, all those other videos were about completely useless engines that are only entertainment value and not functional value. The thing that has brought sense to the idea now is "Super Heated". With that in mind, yes indeed, a steam engine can function at a reasonable efficiency and produce some real work. This is only second vid of yours I watch (Make piston rings was first one) and so, not sure what kind of a steam engine you are making, but as you can imagine, I sure hope it is one that has a usable value, one that uses super heated steam. If this is the case, please make sure we all understand how all the moving pieces get lubrication, and that is another major flop on most if not all the other steam engine builders here, they never properly lubricate all the moving pieces. You explain and teach in what I will term as, as near to perfect as it gets. That is something few yt video teachers even attempt to do. They make a mistake, or do not clarify, they just go on. You obviously clarify every time, it is the added in text things, and so good to see.
Thanks for the kind words! Much appreciated! Yes, my engine will be use super heated steam, and will be used for some purpose (I ultimately want to put it in some kind of go-kart or small vehicle, but we'll see!).
Checkout trainman4602 channel as he's an old school machinist/ pattern maker/ live steam guru that has been building locomotives for years...u just may like him...oh and keep up the great videos!!
Thank you for sharing. This heralds the entertaining factor watching TH-cam. As you probably already know, social media has been saturated with videos on wet steam. Pardon my dry humor, but I propose a third state of steam: Self steam. You see, self steam can be used to pompous up. Why, one day I met this lady ansthesiologist, and let me tell you, she was a real knockout. When I woke up, I applied my self steam to boiler emotions. A year later, we saved our marriage by anointing with makeup water. Good thing, because it is bad to have to resort to cyclamates over bitter new ounces. So water we waiting for? Let's boiler in our self steam! Wait... gotta go. I'm not finished, but my ex just told me to pipe down
Thanks for taking the time to share. This is awesome!

Thanks Craig!
Really enjoying this series, re-learning a lot.
Really good, exactly what I needed

I knew watching this would be informative thanks
that was super useful, thanks!
i wanted to make a steam tesla turbine for a school project and now i know what else to add!
Great job. Thank you!
Good. It is easy to understand. Thank you bro
great video
Hey mate when are you going to create more videos been a while and am looking forward to more episodes
Yes! I just moved (which includes moving my entire shop) and it has been crazy to get back to a place where I can shoot TH-cam videos. :(
great video!
Thanks!
Oh wow!👀 Your explanation was so thorough. I'm just a 15 year old who found this video by chance, but I feel like I really learned something.👏👏👏
Hello, how do I contact the presenter of this content.
Right here, it is me.
Anything below 720 degrees belongs to the saturated or wet steam but at the 720 degree point the steam enters the super-heated stage.
The phases are also a function of pressure. 720 degrees at a particular pressure may be super heated, but at another pressure it won't be. The PT (pressure-temperature) diagram has this relationship.
