Notice the matches ignited but showed no tendency to keep burning. That is mostly because the match head coating (like gunpowder) contains its own oxygen, but once the coating is consumed the steam is actually driving away the oxygen from the air -- which would be needed for continued combustion of the wooden matchstick.
@@Eduardo_Espinozathat’s because the hydrogen and oxygen are stuck together in the form of steam, the oxygen needs to be separate from the hydrogen to facilitate combustion. Elements and alloys do this, they have completely different properties when they’re combined vs when they’re seperate
Buddy of mine was in the navy and told me they looked for steam leaks with wood paddles because of this very demonstration. The steam could slice your fingers off or at the very least burn them to the bone if you didn’t use a paddle. Very dangerous stuff.

My late father served on numerous ships during WWII including steam-turbine powered that used superheated steam. He said the most dangerous part was you could hear a leak but not see it even though it could cut flesh. He described to me hunting SH steam leaks with a piece of toilet paper on a broomstick. Interesting factoid: in regular steam the energy is in the pressure of the steam while in SH steam the energy is in the temperature of the steam.
The Navy still has a few steam ships that use superheated steam. Most of the Wasp class (minus the Makin Island, she's gas turbine) Blue Ridge, Mount Whitney, Frank Cable and Emory S. Land.

Ray Mak, You should really stop with the "surprised" facial expression, it looks really really dumb. The same thing goes with your tongue. So stupid and cringe. I'm very sorry on your behalf.
My father told me when he was in the Navy the boiler room head would demonstrate how dangerous superheated steam can be under pressure by holding a broom handle up to a leak and cutting it in half with the steam. Scary stuff.
During the steam era, locomotive builders had to switch to piston valves when superheated steam was introduced, because it was found that, while it offered better economy, it also badly scorched the valve faces on conventional D-slide valves.
Superheated steam is an important phase used to do the work in shipboard and stationary power generation. Gas turbines have taken over in front line naval surface units, but superheat steam powered turbines are still very much the rule for nuclear powered Super Carriers and nuclear powered Submarines.
I used to do work on naval vessels that had superheated steam lines. The induction warned that if you heard a leak, you'd stand where you were until the leak was found by the navy personnel (presumably using the broomsticks!)
Industrial superheated steam is extremely dangerous. It can cut off an arm or head if someone passes by a pipe leak they didnt know about, which isn't that hard to do because of the noise in industrial settings. Also, the heat isn't always noticeable until too late because the jet of the steam leak tends to induce a lot of cold air around it with vacuum forces.
Very nice for understanding that *the super hot steam* is a very different beast from the regular steam. In the large industrial factories there is steam that is 300º C hot. It's not safe for life and all the pipes are under very hot pressure.
It is very high pressure and it is dangerous, it can literally cut walls. The heat is extra "bonus" Though, despite hot steam being such a beast, my personal favourite is liquid oxygen.
It's not about superheated steam as much as dry steam. Wet stream contains suspended water droplets aka liquid water. Pure dry steam is a gas. There are various ways to get dry steam, a lot of it has to do with piping arrangement. But in theory at least steam can be perfectly dry without being superheated. It's just a lot easier to produce perfectly dry steam when it's superheated.
I guess I always assumed superheated steam was made directly, by boiling water under high pressure the same way that a pressure cooker raises the boiling point of water on a lesser scale. But I suppose it makes sense that you could boil the water first and heat the steam hotter afterwards, like this. And then you'd be moving it farther away from its condensation point at any given pressure, since dryness is likely to be desired.
Yep...the pressure is still about 1 ATM..or 14.7 psia...at that atmospheric pressure water boils at 212 F....but if you add more heat...the vapor move from a saturated state..to an overheated...meaning the pressure is about 14.7....but at a higher temperature...
in the new power plant of our paper mill, a temperature sensor broke out of its fitting. The high-pressure steam at about 500°C = 932°F ignited something combustible causing a serious fire before the boiler could be shut down, and filling the adjacent paper machine hall with smoke and soot. It needed a lot of cleaning, and even the rails and electric contacts of the overhead crane had to be wiped clean before the electricity could be turned on again!

so, what you have proven is the fine line between "saturation" and "dryness" of the properties of steam. Above saturation, the water properties change from a vapor (which is wet) to a Gas (which is dry). Depending upon Pressure, a Gas has properties of wetness until its dry and the heat contained in the Gas remains Superheated until it gives up its heat to remain a gas. At which time, its dryness fraction describes it conditions of being a Vapor.
Thank you very much. I have been thinking about a garage project with super critical steam and I got a bit bigged down with containment. You solved a big problem. As long as there is no need to hold the energy there is no need of a containment vessel. And it's super critical. Thank you.
Hahah! I worked as a janitor at Monroe Power Plant, and one day I noticed a small steam leak from one of boiler feed pumps on Unit Two. Out of curiosity, since this was a "lazy" leak, or just some steam coming off, I put my broom with its plastic bristles into the steam; They instantly curled! That steam, even out of the bad seal, was still so hot it basically destroyed the broom~ My dad was an engineer for Detroit Edison, and told me that the escaping steam was probably 1400 degrees~
As you saw with the match, it ignited because the compounds in the match head react. However, the steam has no free oxygen content and could not support combustion to keep the match burning. The paper equally did not ignite at the steamed area, but outside it, where there is contact with air.

There was a man working for American Crystal Sugar in Grand Forks Minn. that was working on a super heated steam line on a scissor lift. Someone up the line turned on a valve and the man on the scissor lift was burned alive with the super heated steam. ACS kept the death out of the papers so no one found out. I worked there, it is one of the most dangerous places I have ever seen or worked at. One time a fellow fell into and open man hole that was covered with hot water with particles suspended in it. He fell into the man hole and was boiled alive, luckily someone else was there and pulled him out. Severe Burns. Close the Plant. I talked to the EPA and other government entities and ACS told them I was a disgruntled former employee. I am trained as a Civil Engineering Tech. I have land surveyed, project inspector, material testing and I have never seen such flagrant disregard for safety.
What does this have to do with steam? If you forced normal air through those coils and heated them up with a blowtorch would the super-heated air not do the exact same thing? This video should be called "Properties of blowtorches".
The presenter’s eyes were anywhere but on the subject which he certainly didn’t know anything about. Superheated steam is to be taken seriously, he was waving the paper and matches about, not realising he could get badly burned. As engineers, we have to put up with wallies like this all the time.
Fascinating to see the dry stream demonstration for the first time. What surprised me is after being super heated why the dry steam don’t show any pressure on the papers when brought so close? I thought super steam is about 2000 times higher in volume that of water, but the vapour seems to show some visible pressure, indeed.
...the match and paper didn't ignite for lack of oxygen in the steam. had they pulled paper and match out after half a second or so, they would have burnt...
@@fryncyaryorvjink2140 I researched and found out that a match stick Ignites at a temperature of 230°C, while steam is around 100°C. It didn't ignite with normal steam as it just didn't reach its minimum threshold to combust. Superheated steam is about 500°C (maybe more) which is enough to ignite the match head and burn paper.
I actually built a drum set out of a bunch of buckets and pvc piping that each drum was a different size of smoke vortex cannon for a science project in school once! It didnt sound good but it was pretty cool to watch
hahah when he first had the host pick up the normal paper I was thinking wouldn't it be funny if that was flash paper. Well it wasn't but in the end I was not disappointed. ;-)
I work with overheated steam. It's around 420 degrees celsius when it hits the turbine. I would never put a flash paper in front of anything lol. The pressure is 40bar+ so if there's a leak you will notice it by the sound! And the water has no oxygen at all, or close to nothing(deionized). That would end the lifespan of the boiler rather quick. And you can't see any steam when it hits the high temperatures.
@@Jon-em4kc in superheated steam the energy is in the temperature of the steam not its pressure. You can pipe superheated steam all over a vessel without the pressure blowing out the pipes.
Might be because I'm not a native speaker, but doesn't superheated mean "heated beyond the temperature the aggregate state changes at a given pressure"? So superheated water being very clean water heated to above 100°C at 1000 hPa but still not boiling because of the lack of cristallisation cores in the water. Happens in a microwave from time to time... And supercooled water being the same at below 0°C at 1000 hPa. .. and "superheated steam" would make limited sense, because the next 'aggregate state' would be plasma, and you can't really keep plasma from forming the same way you can prevent a change from liquid to solid or gaseous...
This was not a lecture in thermodynamics. This was a demonstration to advertise the imagination station which is a place to introduce students to scientific concepts to get them interested so that they will go and study science once they are in college. Nothing more, a dog and pony show. You would introduce this to children as "Can water light a match?" The children would respond by saying of course not. Then you show them this demonstration. The guy was not designing steam systems. He was advertising the events that were happening at the Imagination Station, which is like a museum with (as much as possible) hands on demonstrations to get children interested in science.
Dealing with something harmful that you can't see with no protection on his hand and forearm. Great stuff. Tomorrow we stand next to a spinning propeller and put paper in it.
It is an often quoted fact that a broom handle can be used to locate steam leaks on an industrial boiler. It should come as no surprise then that the cleanest kitchen floors are those that have been swept with superheated steam.
I work in Oil refinery and I do work with super heated steam, i have heard from my supervisor that it can actually cut thru bones (i doubt it) but the way we find leak is actually using boiler water on location and the steam vapor will show for short period,
I found this years later, but interesting, I used to hold a boiler Operator License in Ohio, it was low pressure, but I studied to get my engineers license, but moved away before I had a chance to take the test, secondly I looked at the closings at the bottom of the screen, I remember all those places. I used to live in Bowling Green, Ohio, I used to watch channel 11 all the time.
LMAO 0:33 i thought they were panning in on the host's face because he didn't know anything the presenter was saying it works perfectly too like the camera movements in the office 😂😂
You can even light a fire with ice you found on the ground. 1. Take fist sized piece of ice 2. Melt it to a sphere in your hands 3. Focus sunlight on flammable material
This kind of steam is exceedingly dangerous. A lot of industrial workers will wave long sticks or brooms around superheated steam pipes to check for potential leaks, because just simply walking by it for just a split second will absolutely slice you. I work with a lot of high-pressure steam at my workplace, and that in itself can be terrifying on its own, but it's not nearly as scary as superheated steam. At least I can see where I might have steam leaks at my workplace. I can easily avoid it altogether, but others might not be so lucky.
Where I work we use super heated steam in extruders to make breakfast cereal. When it comes time to clean the extruder you have build up of black burnt grains. You can cook the ingredients in a matter of seconds.
Once when I was young, I tried to pull in the steam from kettle to puff it out like smoke from a cigarette. Burned my lips terribly and learned a lesson.

Awesome demonstration! I'm fascinated this was on a broadcast station! 👀😁
I get the vibe they don't like each other lol
The tension between these two could light that soggy match.
If you know what you're doing, you're a good presenter.
Except it is condensed *WATER* not condensed air !!
So much for being "good".
There was a man working for American Crystal Sugar in Grand Forks Minn. that was working on a super heated steam line on a scissor lift. Someone up the line turned on a valve and the man on the scissor lift was burned alive with the super heated steam. ACS kept the death out of the papers so no one found out. I worked there, it is one of the most dangerous places I have ever seen or worked at. One time a fellow fell into and open man hole that was covered with hot water with particles suspended in it. He fell into the man hole and was boiled alive, luckily someone else was there and pulled him out. Severe Burns. Close the Plant. I talked to the EPA and other government entities and ACS told them I was a disgruntled former employee. I am trained as a Civil Engineering Tech. I have land surveyed, project inspector, material testing and I have never seen such flagrant disregard for safety.
Properties of superheated steam:
It's hot
The guy didn't realize the steam was also blowing out the natch once lit. He should've pulled it away as soon as it lit
That is a load of hot air.
What does this have to do with steam? If you forced normal air through those coils and heated them up with a blowtorch would the super-heated air not do the exact same thing? This video should be called "Properties of blowtorches".
The presenter’s eyes were anywhere but on the subject which he certainly didn’t know anything about. Superheated steam is to be taken seriously, he was waving the paper and matches about, not realising he could get badly burned. As engineers, we have to put up with wallies like this all the time.
Peter Gregory the kid works at the imagination station LOL 😂 GIVE ME A BREAK
Fascinating to see the dry stream demonstration for the first time. What surprised me is after being super heated why the dry steam don’t show any pressure on the papers when brought so close? I thought super steam is about 2000 times higher in volume that of water, but the vapour seems to show some visible pressure, indeed.
...the match and paper didn't ignite for lack of oxygen in the steam. had they pulled paper and match out after half a second or so, they would have burnt...
if so... then why did it burn with the overheated steam?
Match stick burnt because it didn't need oxygen, the match head have the ingredients. Paper didn't.
Could be a good way to char things without them catching fire
@@fryncyaryorvjink2140
I researched and found out that a match stick Ignites at a temperature of 230°C, while steam is around 100°C. It didn't ignite with normal steam as it just didn't reach its minimum threshold to combust. Superheated steam is about 500°C (maybe more) which is enough to ignite the match head and burn paper.
AxA12 - you didnt pay attention.
This is an old video and yet by reading all the comments, I learn more about water steam than what I got from my high school STEM classes
Me to my parents at 1:07
Mine are getting super annoyed every time they hear "And the reason for this..."
Actually everyone close to me but few are 😂
😂😂😂
I actually built a drum set out of a bunch of buckets and pvc piping that each drum was a different size of smoke vortex cannon for a science project in school once! It didnt sound good but it was pretty cool to watch
hahah when he first had the host pick up the normal paper I was thinking wouldn't it be funny if that was flash paper. Well it wasn't but in the end I was not disappointed. ;-)
FANTASTIC EXPLANATION . THANK YOU VERY MUCH
I work with overheated steam. It's around 420 degrees celsius when it hits the turbine. I would never put a flash paper in front of anything lol. The pressure is 40bar+ so if there's a leak you will notice it by the sound! And the water has no oxygen at all, or close to nothing(deionized). That would end the lifespan of the boiler rather quick. And you can't see any steam when it hits the high temperatures.
40 BAR 420 c sounds surreal. impressive
40bar? Is that all? 😂
@@Jon-em4kc in superheated steam the energy is in the temperature of the steam not its pressure. You can pipe superheated steam all over a vessel without the pressure blowing out the pipes.
once a tiny 3 bar silicone hose slappede me @@Jon-em4kc
dude hot stuff and paper is always a good combo. def good enough for the news
Might be because I'm not a native speaker, but doesn't superheated mean "heated beyond the temperature the aggregate state changes at a given pressure"?
So superheated water being very clean water heated to above 100°C at 1000 hPa but still not boiling because of the lack of cristallisation cores in the water. Happens in a microwave from time to time...
And supercooled water being the same at below 0°C at 1000 hPa.
.. and "superheated steam" would make limited sense, because the next 'aggregate state' would be plasma, and you can't really keep plasma from forming the same way you can prevent a change from liquid to solid or gaseous...
This was not a lecture in thermodynamics. This was a demonstration to advertise the imagination station which is a place to introduce students to scientific concepts to get them interested so that they will go and study science once they are in college. Nothing more, a dog and pony show.
You would introduce this to children as "Can water light a match?" The children would respond by saying of course not. Then you show them this demonstration. The guy was not designing steam systems. He was advertising the events that were happening at the Imagination Station, which is like a museum with (as much as possible) hands on demonstrations to get children interested in science.
Dealing with something harmful that you can't see with no protection on his hand and forearm. Great stuff. Tomorrow we stand next to a spinning propeller and put paper in it.
Kids too smart for America
It is an often quoted fact that a broom handle can be used to locate steam leaks on an industrial boiler. It should come as no surprise then that the cleanest kitchen floors are those that have been swept with superheated steam.
Woohoooooo.. anyone here in 2019
Happy New Year!
STFU man, you're too loud. Be sensitive to those mourning 2018. Plus I still have a hangover.
Duciousness 😁😂🙊
The visible part of steam is not the condensed air molecule rather it is the vaporised water molecule condensed in contact with air.
3:42 oh he felt the magic for a second there
This imagination station need their own channel
I work in Oil refinery and I do work with super heated steam, i have heard from my supervisor that it can actually cut thru bones (i doubt it) but the way we find leak is actually using boiler water on location and the steam vapor will show for short period,
So that's why I keep burning my pants after chipotle
I tought youtube recommended another crazy tv fail. i was waiting for something to happen to the news guy lmao
I found this years later, but interesting, I used to hold a boiler Operator License in Ohio, it was low pressure, but I studied to get my engineers license, but moved away before I had a chance to take the test, secondly I looked at the closings at the bottom of the screen, I remember all those places. I used to live in Bowling Green, Ohio, I used to watch channel 11 all the time.
This won't leave my recomended videos for the past three days.
LMAO 0:33 i thought they were panning in on the host's face because he didn't know anything the presenter was saying it works perfectly too like the camera movements in the office 😂😂
What you can't see...is much worse than what's visible in physics at times
Dry steam is dangerous.
The tv guy coupled with the weird camera zooms reminds me of Michael Scott in The Office o_o
Lol and the whole time he's glancing over at his stage manager, like "jeazzz, this kid, right?"
Cool!! Awesome demonstration
You can even light a fire with ice you found on the ground.
1. Take fist sized piece of ice
2. Melt it to a sphere in your hands
3. Focus sunlight on flammable material
This guy is the actual physical embodiment of Michael Scott.
As usual, everyone is an expert on steam and hosting. Great work everyone! Now back to sitting on your chair eating butter.
Some of us are experts in steam and make a comfortable living out of it 😊👍
I died inside for watching this. The host is a black hole of charms.
Not at all a critique here.. But the host interactions + his suit + his gaze sometimes.. that's Michael Scott all over. Awesome video.
This kind of steam is exceedingly dangerous. A lot of industrial workers will wave long sticks or brooms around superheated steam pipes to check for potential leaks, because just simply walking by it for just a split second will absolutely slice you. I work with a lot of high-pressure steam at my workplace, and that in itself can be terrifying on its own, but it's not nearly as scary as superheated steam. At least I can see where I might have steam leaks at my workplace. I can easily avoid it altogether, but others might not be so lucky.
Very cool. "I brought the steam, baby!"
Where I work we use super heated steam in extruders to make breakfast cereal. When it comes time to clean the extruder you have build up of black burnt grains. You can cook the ingredients in a matter of seconds.
Once when I was young, I tried to pull in the steam from kettle to puff it out like smoke from a cigarette.
Burned my lips terribly and learned a lesson.
on todays episode of: if we make something very very hot it can burn things, incredible....
4:25 Science guy recovery from the attempted handshake.
