“It really doesn’t require manpower or animal power, it can run so fast!”
Zhu Yuanzhang, who leaned his upper body out of the window, felt the strong wind blowing in front of him, the scenery in front of him that was rapidly retreating, and the steam train that continued to advance rapidly beneath him.
He was also so shocked that he couldn't help but mutter to himself.
After quite a while, Zhu Yuanzhang heard Yan Changqing shouting in the carriage:
"You can just feel it for a while. Now take your heads back."
"Otherwise, if you stick your head out of the window for a long time, even if you don't touch anything, being blown by the strong wind all the time is not good for your health.
After hearing Yan Changqing's cry, Zhu Yuanzhang, Zhu Biao, and the other six ministers, nine ministers and ten princes also took their heads back.
Then Zhu Yuanzhang looked at Yan Changqing with interest and asked:
"How can this train run without human or animal power?!!"
Zhu Yuanzhang is now very interested in steam trains, and it can even be said to be his first interest in life.
So much so that Zhu Yuanzhang had the idea of learning how to make a steam train, and then go back and try to make a steam train himself.
Hearing Zhu Yuanzhang's inquiry, the other six ministers, nine ministers and ten princes also looked at Yan Changqing expectantly and curiously. They were also very interested in the steam train.
Seeing that everyone was focusing on him, Yan Changqing pointed to a briquette stove that was heating hot water next to him and said with a smile:
"The principle of the steam train is very simple, that is, boil water!!!"
As soon as Yan Changqing said these words, everyone present, except Zhou Wang Zhu Ju, seemed to have a big question mark on their heads, and said with doubts on their faces:
"boil water?!!"
“The reason why this train can run is because it boils water?!”
"Kesheng, did you make a mistake by mistake?!!"
"Is it because I am old and my ears are weak, so I heard wrong?!!"
"How can boiling water make such a big thing run?!!"
Yan Changqing smiled and shook his head and said:
"I said it right, and you heard it right too."
“The operating principle of a steam train17 is to boil water!”
Then Yan Changqing took another teapot on the table next to him and explained with an example:
"You should have boiled water and made tea at home every day, right?!!"
Everyone present nodded. It was an elegant thing to make tea around the stove. Naturally, they would make tea and drink it at home with their relatives or friends.
Seeing that everyone present nodded, Yan Changqing continued to guide further:
"Then you must have noticed that when the tea is boiling, the hot steam rising inside the teapot will push up the teapot lid from time to time, right?!!"
Everyone present still nodded after hearing this. They did see this phenomenon often. Generally, when they see this phenomenon, they know that the tea is boiling and it is time to make and pour tea.
Then Yan Changqing took another belt and placed it on the lid of the teapot, and continued to guide:
"Then if I put a belt on this teapot, the left end of the belt and the left end of the teapot are tied and fixed, and the right end of the belt is relatively unfixed.
"So when the teapot lid is pushed up by the water vapor in the teapot, will it push up the straps on the teapot lid too?!!"
"So when the belt is pushed up, the left side of the belt is fixed and cannot move. Then, the right side of the belt that is not fixed will be pulled from right to left because the belt is pushed up? !!"
Hearing this, everyone present was a sensitive person, and they had already vaguely thought of what the next step would be.
Yan Changqing glanced at Zhou Wang Zhu Zhu below, and Zhou Wang Zhu Zhu understood immediately, then stood up and stepped forward to help Yan Changqing hold the teapot and assist in the demonstration.
Then Yan Changqing tied the left side of the strap to the left side of the teapot, then picked up a teacup lid and stood it up to imitate a wheel. [Then he tied the right side of the strap that was relatively unfixed to the handle of the teacup lid. .
Finally, Yan Changqing took out another gear and placed it between the teapot lid and the teacup lid, and continued:
"As I just said, when the teapot lid is lifted up due to the steam boiling inside the teapot, the strap placed on the teapot lid will also be lifted up."
"When the strap is pushed up, the right side of the strap, which is relatively unfixed, is pulled from right to left."
"When the strap is pulled from right to left, the gear between the teapot and teacup lids is forced to rotate."
“When the gear in the middle rotates under force, it will pass through the mutual transmission between multiple gears, and finally rotate the teacup lid as a ‘wheel’.
“And if a carriage is placed on top of the tea cup lid that represents the ‘wheel’, then a steam train will be completed. "
"To put it bluntly, a steam train boils water by burning coal, and then uses the water vapor generated after the water is boiled as the source of power.'
"Finally, this source of power is used to drive the mechanical gears to perform a reciprocating mechanical motion, so that the steam train can be driven without any human or animal power, so that it can keep moving forward."
"Of course, the above is just the simplest operating principle of a steam train."
"In fact, if we want to put this operating principle into practice, we need to solve many problems."
"For example, there are issues such as the sealing of the steam cylinder, the heat energy transmission loss of water vapor, and the prevention of boiler explosions caused by steam overpressure."
"In order to solve these problems, we have just spent five years of development time."
After reading Yan Changqing's demonstration and explanation, whether it was Zhu Yuanzhang, Zhu Biao, or the Six Ministries, Nine Ministers and Ten Kingdoms Dukes, they could not help but be impressed by Ban Heng, the sage of science.
Boiling water can be seen everywhere in daily life.
There are now 80 million people in the Ming Dynasty. Not everyone has boiled water with their own hands, but at least more than 7,000 people have boiled water with their own hands.
In other words, at least more than 70 million people have witnessed the phenomenon that after water is boiled, the water vapor generated will lift the cup lid from time to time several times, or even countless times.
But among the more than 70 million people, only Kesheng Ban Heng noticed this phenomenon, and was able to further divergently think that water vapor can be used as some kind of power.
In the end, he even transformed his idea into reality and developed a steam train!
With such vision, mind, and ability, it is no wonder that among the 80 million people in the Ming Dynasty, only one person, the Ban Heng family, could become a scientific sage!
"If you are interested, you can also take a look at the boilers, steam engines and other equipment in front."
Looking at the people who had initially understood the operating principles of steam trains, Yan Changqing suggested again.
Hearing what Yan Changqing said, Zhu Yuanzhang, who was sitting at the front, responded unceremoniously:
"Then go and have a look."
Zhu Yuanzhang has spoken, so naturally Zhu Biao, Zhu Yunxi, Zhu Youdou, and the other six ministers, nine ministers and ten princes have to follow.
As for Queen Ma, she was not very interested in it, while Zhou Wang Zhu stayed with Queen Ma.
Immediately, Yan Changqing opened the connecting door between the current car and the previous car, then walked forward and introduced:
"The carriage we are currently in is the first carriage carrying passengers."
"In front of this passenger carriage, there is a steam locomotive, a boiler carriage, and four carriages containing pulverized coal and water."
"The sides of the closed carriage we are passing through now contain pulverized coal and water used as fuel."
"As long as the pulverized coal and water in these four carriages are used up, this steam train can keep going day and night."
"Generally speaking, we will prepare numerous fuel cars pre-loaded with pulverized coal and water at every train station."
"When the steam train reaches the next train station and passengers get on and off the train, the first passenger car will be briefly disconnected from the fuel car in front."
"Then the steam locomotive, boiler car and four fuel cars will drive into the fuel car replacement area of the train station."
"Then the steam locomotive and boiler car will be disconnected from the fuel car that has burned out the pulverized coal and water, and then reconnected to the fuel car that has been filled with pulverized coal and water in the fuel car replacement area."
"Finally, the steam locomotive and boiler car will take the fuel car filled with pulverized coal and water, exit the fuel car replacement area of the train station, return to the original position, and then be linked to the original passenger car again." ”
“Finally, after all the passengers who should transfer have boarded and disembarked, the steam train will restart and then continue traveling towards the next train station.
"Generally speaking, whether it is the passenger transfer process or the fuel compartment replacement process, it can basically be completed within half an hour.
"Okay, here is the boiler car."
Following Yan Changqing's introduction, Zhu Yuanzhang and his party also quickly passed through the narrow carriage passage with a width of only about one meter in the middle of the four fuel carriages.
As soon as they stepped into the boiler car, Zhu Yuanzhang and others felt a wave of heat coming over them.
The several masters in charge of burning the boiler in the carriage also had to salute Zhu Yuanzhang, Zhu Biao and others on the spot. However, Zhu Yuanzhang was also a person who could distinguish the occasion. The words "no courtesy"1 saved the boiler master from all the red tape. .
Looking at the boiler in front of him that was taller than others, as well as the tracks on the left and right sides that seemed to be continuously transporting pulverized coal into the boiler without the need for human power, and the open windows, Zhu Yuanzhang also happily asked the boiler master to He introduced one or two in detail.
"Your Majesty Taishang, please see, this is the boiler in front of you. When the train stops, we will reduce it or stop shoveling the pulverized coal while ensuring that it does not go out."
"When the train is about to start, we shovel a large amount of pulverized coal into it, causing it to start burning violently."
"When the boiler temperature rises rapidly, a large amount of water vapor will be generated inside the boiler, and this water vapor will be transmitted to the previous steam engine.
"The steam engine in front will use this continuous water vapor cycle to continuously make mechanical piston movements."
"The continuous mechanical piston movement of this cycle will start to drive the boiler car forward, and then the boiler car will drive the connected fuel car, and then the fuel car will drive the connected passenger car behind."
"Eventually, the whole steam train starts to move forward."
"When the steam train starts moving forward, the transmission tracks between the boiler car and the following fuel cars will also be driven.'
"Generally at this time, manpower is no longer needed to shovel pulverized coal into the boiler car. The conveyor belt will automatically transport the pulverized coal from the fuel car at the back here, and then automatically dump it into the boiler."
"What we have to do is to control the amount and speed of pulverized coal pouring according to the train driver's instructions."
"If we want to slow down
If the speed of the train increases, we will reduce the amount of pulverized coal poured and slow down the pouring speed of pulverized coal.
"Similarly, if we want to speed up the train, then we will increase the amount of pulverized coal poured and increase the pouring speed of pulverized coal."
"The open windows on both sides are mainly for ventilation."
One of the older boiler masters also knew everything, and introduced Zhu Yuanzhang endlessly about various things in the boiler car.
Hearing this, Zhu Biao couldn't help but ask 517:
“Can a steam train really reach a speed of 60 to 80 kilometers an hour?!!”
"From Yingtianfu to Songjiangfu, does it really take just a few hours to get there?!!"
Another boiler master, who looked a bit honest, also nodded and affirmed:
"OK!"
"We have tested it with Mr. Ke Sheng before, and the current average speed of the steam train can be stably maintained at about 160 kilometers an hour."
"The current maximum speed of steam trains can even reach 90 kilometers an hour."
"But Mr. Ke Sheng said that once the current speed of steam trains exceeds 80 kilometers an hour, braking control will be difficult and accidents will easily occur.
"So until a better method of braking and controlling steam trains is developed, Mr. Ke Sheng will just let us keep the maximum speed at about 80 kilometers an hour."
"We set off at around 8:30. According to the current speed, we will arrive at Songjiangfu Railway Station at around 12:30 at the earliest, and at 1 noon at the latest.
Arrive at Songjiangfu Railway Station around 30:30. "
After hearing the boiler master's personal confirmation and the scenery outside the window of the boiler carriage that was rapidly regressing at this moment, Zhu Biao finally confirmed and believed that from Yingtian Mansion to Songjiang Mansion,
More than 300 kilometers, it really only takes four or five hours!
Think about the time when he was still the prince and concurrently served as the magistrate of Songjiang Prefecture Coastal New Area.
Before the concrete road was built, it would take him about half a month to go from Yingtian Mansion to Songjiang Mansion.
Because the road was really bumpy and uneven, plus he was riding in a carriage, and he needed to rest at night, and he also needed to eat, go to the toilet, rest, etc. during the day.
So after twenty-four hours a day, he only walked a distance of about twenty kilometers.
After the concrete road was built, it would take him about four or five days to go from Yingtian Mansion to Songjiang Mansion using the same rushing method just mentioned.
In other words, in twenty-four hours a day, he can walk a distance of about 60 kilometers to 80 kilometers.
This is the three to four times improvement in speed and efficiency brought by concrete cement roads!
Originally, he thought that concrete roads were truly invincible, but he never expected that something as outrageous as a steam train would happen again.
A steam train can travel 60 to 80 kilometers in just one hour, which is the total distance traveled by horse-drawn carriage in 24 hours a day!
In other words, the speed and efficiency improvements brought by the steam train are twenty-four times that of riding a horse-drawn carriage on a concrete road!
And if this 24-fold improvement in speed and efficiency is brought to all other aspects of the world, Zhu Biao simply cannot imagine what it will bring to all walks of life and everywhere in the world.
What a huge impact and change!
