Nice Explanation. Thank you 😇
Replace a conventional fire tube boiler with OTSG modern technology
Wonderful presentation.
Very nice presentation 🎉
And steam turbines using coal to make elec still exist...how backwards is that. Tech that is 130 years old.
Very good narration and delivery of information, thank you!
Excited about our collaboration. Looking forward to the next one.
@RossMaynardProcessExcellence Are you available for a business chat regarding your Udemy course? On getting you more sales, Real and active student with 5 stars positive reviews I don't know if you might be available for a brief call please. I'll be looking forward to your response. Thanks
Excellent presentation, so the two new standards are changing the reporting landscape.
Thank you. You'll need to do the detailed research to see how it applies to your organisation.
Thanks for sharing ❤
Can I please have this pdf to prepare for a Finance business partner interview?
In Britain from 1800 to 1900. 20,000 Waterwheels decreased in number. Windmills decreased in number. The Englishman Thomas Newcomen's 1,500 Atmospheric Pumps disappeared. The Scotsman James Watt's 500 Steam Engines and their descendants increased in number to 10,000,000 !!! So for every SINGLE Waterwheel in 1800, we now had 500 James Watt Steam Engines and their descendants in 1900 !!! The Power output and Productive capacity for the whole country increased by 500 times !!! This WAS the Industrial Revolution, and it was all kicked off by only one single Invention. James Watt's Invention of the world's first PRACTICAL Steam Powered Engine!
Just winderful, thank you for this
Any old pictures of the large locomotive work in Springburn Glasgow.
There were 4 large loco an carriage works in Spring burn - Cowlair, Hyde Park, Atlas and St Rollox. There are some photos on railscot co.uk and I think some published books have photos. Many of these will be copyright protected and cannot be published online.
Thanks for this great posting, when I was at secondary school our class was taken to the locomotive works at this point while still operating it had the appearance of decline.
Top Hat Mercenary Confederation: “An Unreliable Locomotive that needs Improvement? *CHALLENGE ACCEPTED.* “
Enjoyed your video but would like to point something out. The Monkland Canal terminated at the junction of Castle Street & Alexandra Parade. The section of canal between there & Port Dundas - called the "Cut of Junction" - was neither part of the Forth & Clyde or Monkland Canals. The Glasgow Branch of the Forth & Clyde ran from Stockingfield Junction to Port Dundas. Hope you don't mind my saying !
Thank you, I didn't know that. I thought the Monklands Canal had always run from the bleach works.
@RossMaynardProcessExcellence the Cut of Junction was built after the other two canals. One of the reasons was to use the Monkland as a water supply for the Forth & Clyde - which it still does via the pipes under the M8 (which was originally called the Monkland Motorway).
More corporate virtue signalling that doesn’t really do a hell of a lot
Let me get pdf files of this presentation
I've added a link to the PDF of the slides in the video description.
Hi. Actually, geared steam turbines on ships ARE reversing, although at much lower power than in forward. A few spools are included for reversing, and these must be evacuated during normal operation so as to reduce windage from the reverse spools. Turbine-electric units ought to be similar in operation to diesel-electric units. Basically, steam is a nuisance to deal with except for large, stationary power plants, where their use is still common.
Would this work if I don't record a video but just add my recorded audio?
Mmm. You'd have to experiment. You can insert an audio file into a PowerPoint and set it up to play. The question is could you get it to automatically scroll through the slides at the right points? I suppose you could advance them manually when you hear the audio get to the right point. If you want the presentation to advance automatically with the audio playing I think you would have to "record" the presentation with the audio playing, advancing the slides yourself and then export it as an MP4 - which is basically what I demonstrated in the video.
yeah they were inefficient, but you cant deny the concept was/is dope af
The exception is the m3t class used by TGOJ in Sweden I think. Three were built between 1930 and 1936 and were used to haul iron ore. They were withdrawn from service in the 1950s when the line was electrified. The locomotives were placed in Sweden's strategical steam reserve and thanks to that all three survive and one of them was used to haul the last ore train when the mine shut down in 1990 (video of it is available on UA-cam).
If I was wealthy, I'd build a new design steam turbine locomotive just because I want to own one so badly!
Excellent presentation
Hay
Steam turbines both on board ships and in stationary power plant service operate in clean engine rooms at a near constant speed. Both can also use condensers at the turbine exhaust to lower the pressure of the exhaust down to near zero, making steam turbines even more efficient. And both use high pressure water tube boilers instead of the fire tube boilers used by most steam locomotives, which enables them to reach steam pressures much above the 500 PSI max of steam locomotives (the only exception being a handful of water tube boiler equipped but otherwise conventional steam locomotives.) That makes them even more efficient. The two 1939 GE steam turbine locomotives built for the UP, the ones built for the C&O, and the "Jawn Henry" for the Norfolk and Western Railway were all basically steam-electric power plants on rails, like their marine and power plant cousins. The UP steam turbine locomotives were even equipped with condensers. But, as pointed out in the video, these power plants were more complicated and more fragile than a convention steam locomotive or even a diesel locomotive. They were could not coup with the hard coupling, start-stop, and dirty life a locomotive leads. They also had problems with ash and soot from the boiler getting into and shorting out the traction motors. Their added expense and reliability issues outweighed any performance benefits gained, which is why all were scrapped in just five years or less. There was a serious study put together in the 1950s for a nuclear-powered locomotive which would have replaced the boiler with a tiny nuclear reactor surrounded by tons of lead shielding. It would have powered a steam turbine, and what looked like a B unit behind it was in fact a condenser. It promised a power rating of about 10,000 HP which interested railroads like the UP, but the million-dollar estimated cost for each locomotive, combined with handling the nuclear fuel (weapons grade uranium mixed with sulfuric acid) resulted in it never getting past a paper study. I have a video about it on my channel.
Informative presentation 👌
Thank you for this informative, summarized, and well-presented video.
I think that the development of diesel-electric is also a factor.
More videos on IFRS please. Thank you for this video.
P R O M O S M 🤷
As a designer with a deep interest in steam locomotion, i actually have a side project designing and making a working scale model of a team turbomotive locomotive, styled in streamline moderne. I even tried out a few ideas to solve the low speed inefficiency of the turbine
really appreciated the video
Factories have been around since the stoneage!
James Watt didn't improve Newcomen's atmospheric engine (which supplied atmospheric power). He improved his own engine (which supplied steam power) with an optional separate condenser. It could work without a codenser. Newcomen's engine was an atmospheric engine. Even at 100% efficiency it would only provide a maximum of 14.7psi of air pressure Watt's engine was a steam engine. It provided a lot more power and, for the first time, could provide rotory power. It was the one and only invention that created the industrial revolution. It was a power revolution. Watt dumped Newcomen's atmospheric power for steam power, and made it work for the first time in history. Watt invented the first practical steam engine.
Newcomen's engine used atmospheric power. It didn't use low pressure steam, it used no - pressure steam! Watt's engine supplied high pressure steam power. The world's first practical steam engine. I fail to see the difference between high and low pressure steam! They're all steam engines! Watt couldn't do everything, he was long gone before we had a practical locomotive. But he kicked everything off! Steam pushed out the air in the cylinder? Steam pushed the piston down the cylinder! A locomotive is a Watt engine on wheels! The vacuum didn't draw the piston down, steam pressure pushed it down! Like atmospheric pressure pushed Newcomen's piston down! On a visit to the Boulton and Watt factory, Trevithick's grandfather pinched a Watt diagram. They had to demand it back again! Newcomen had nothing to do with the invention of Watt's steam engine.
Newcomen's Atmospheric Pump didn't supply Steam Power, it supplied Atmospheric Power. Watt's engine supplied High Pressure Steam Power, ( there's an Industrial Revolution's worth of difference ). You forgot to mention Watt's dumping of Newcomen's Atmospheric Power and Arkwright's Water-Power for High Pressure Steam Power! Newcomen's steam engine didn't exist, it was an Atmospheric Pump, it couldn't supply rotary motion and had a limit of 10psi of air pressure. It could only pump. In all the videos I've watched, the change from Newcomen's Atmospheric Power and Arkwright's Water-Power to Watt's High Pressure Steam Power is strangely absent. And, surprise surprise, even in this one! There's nothing complicated about it, but it's never mentioned. The crucial change! The most complicated part is building an engine to supply High Pressure Steam Power, and Watt did that. He invented the first PRACTICAL High Pressure Steam Engine! And created the Industrial Revolution.
I agree with your distinction. However, I was trying to create an understandable script for the layperson which resulted in me avoiding technical complexity in favour of a straightforward narrative. That is probably true of other developments covered in the videos.
Thank you for providing so much background history to the Springburn area.
Looking at Google maps , looks like the Goods shed has now been demolished 😞
Watching this the night before a test at 9 o clock
Terrific video RS, MD FRCS Canada
Very good discussion
Could not a hybrid of both types be used, I wonder why this was never tried
I imagine weight and cost would be the main issues. A loco with two engines would be huge and probably too heavy for the tracks. It would also cost a lot more than a standard engine. Also, steam turbines were coming on the scene just as diesel engines were being developed and diesel wins on cost, flexibility and maintenance.
Hybrid nice idea.. Can we eliminate coal! The hammer blow on the railroad gets eliminated with the connecting rods gone.. Correct me if I'm wrong.. High Pressure steam operates the turbine.. Once this steam exits the turbine it's low pressure. Is the low pressure steam utilised or wasted? What will be the power to weight ratio? Can there not be a system wherein the well utilised steam exit to the tender back as water?
insightful sharing!
Ross, I have 12 slides and 12 .wav files, 1 for each slide. Is there a way to import the audio for each slide and have the slide automatically advance (transition) when the audio playback of each slide finishes? I guess I could use Audacity to concatenate all the 12 audio files into 1 mega file, but then I have to go through the hassle of trying to perfectly time the slide advance manually. What Microsoft should do is on the audio recording menu, there should be an option to "import audio from a file" for each slide - but I guess they didn't think about that. Any ideas?
Hi Chris, this is something I have never tried before so what I am suggesting is a complete experiment. You can insert audio into each slide, so I would do that. Put each WAV file into its respective slide and select "play automatically" in the audio options. You then need to set up the slide show to move through each slide automatically by setting up the timer between each slide. The problem is that you need to set the interval for each slide to slightly longer than the audio needs to play. That will likely take some trial and error and ,personally, I think that would be more hassle than combining the audio into one file in Audacity and doing the manual slide advance. I know it's a chore but it is probably the easiest way. Good luck!

Can you tell me which engine requires more steam pressure to run.? 1. Steam turbine 2. Steam piston
I am not a steam engineer so cannot fully answer your question. However, I think the answer would depend on the size of the engine. Steam pistons can work at relatively low pressures as in Newcomen's and Watt's low pressure engines. A steam turbine requires high pressure steam. In short then, my view is that a turbine generally needs higher pressure steam.
Can i suggest.... Let the turbine run at its own speed can we not regulate it through gears for starters, then research on whether they can under low pressure giving out the same torque... I am not a qualified engineer though...also making sure they be able to pull at the least 25 carriages...
@@RossMaynardProcessExcellencesteam turbine is honestly can be efficiënt its not very difficult to create more torque at lower speed you need planetary or large to small gear wheel to greater more best way to create more electricity is mix planetary an large to small gear wheel box to greater more rotation at low speed an if you have an steam tank where only steam goes in an pressure it to an certain bar than you can have an efficient power but if you do direct to the turbine than you dont get enough power if you do study on pressure an bar with air to calculate what is best way to get enough power than you Calculate in steam an if you replace coal to an gas flame an hold it under the water boiler you get more steam pressure
The steam turbine electric replaced a heavy and complicated gearbox with a generator at the end of the steam turbine and traction motors at the wheels, just like a diesel locomotive. The advantage of a turbo-electric drive is that the steam turbine could run at full speed/max efficiency without use of a heavy gearbox and transmission. Reversing is also easy, just like a diesel locomotive. The main problem, and one that could not be overcome, is that soot and ash from the boiler would get into the traction motors, shorting them out. I believe the Northern Pacific used the Union Pacific 1939 GE steam turbine locomotives after the UP rejected them because of wartime power shortages. A GE engineer working with the locomotives managed to get most of the issues resolved; but they were still more complicated than a conventional diesel-electric locomotive and were scrapped as soon as they could get rid of them. Most diesel locomotives also use a generator and traction motors because they are lighter, easier to design, and can take high horsepower better than a mechanical gearbox and transmission. Only small diesel locomotives were able to use a mechanical gearbox; the Germans and a few others built locomotives with hydraulic transmissions; but they never caught on as well as a diesel electric. Finally, steam turbines do work better with high pressure steam (above 500 PSI), exhausting into a condenser, which allows the pressure at the exhaust end to be near zero PSI. Many of the steam turbine locomotives had high pressure fire tube boilers instead of conventional water tube boilers found on steam locomotives; the 1939 GE steam turbines built for the UP even had condensors. But the start-stop, hard coupling, and dirty life of a locomotive was poorly suited to such a power plant, so tube failures and other failures were common on what was already a very complicated locomotive. I believe the Northern Pacific operated them in the Northwest, on a transcon line that had few stops, which helped a little.
So nothing to do with gaslighting, closing of ranks, and or, wilfull negligence then?? Just completely the same old narssistic lack of accountability by a really unprofessional, murderous, Orwellian control freak healthcare system that is putting personal grievances before patient care?! Diabolical charlatans that can only mean one thing: the Nhs is not fit for purpose and is completely Fascist! I've witnessed what these incompetent charlatans stand for?! It should send chills down peoples spine regarding the extent of Evil that exists within this poxy institution?!
Thanks for posting. My Great Grandfather was an apprentice at the Hyde Park Works. In 1912, He with many other Scots Engineers went to South America and helped design and build the South American and Argentine Railway Systems. He became one of the Head Engineers in Buenos Aries..Then came back to Scotland to retire.
