Hu Changan took out a small dustpan from his pocket, put a little coal in it, walked to the stream, and started shaking it up and down.
Suddenly, everyone looked like they wanted to laugh but were afraid to laugh, not to mention how hard it was to hold it in.
I didn’t expect that this young master actually washed this black stuff into the water. Did he want to wash this black stuff white?
It's simply childish and ridiculous.
Hu Changan ignored everyone's strange looks.
Seeing that the time was almost up, Hu Changan took out the dustpan, took the wet coal on the top aside, pointed to the sand and gravel at the bottom and said to everyone: "Everyone, what we need is just a layer of black coal on the top.
s things."
"This thing is called coal, and it is an excellent fuel, whether it is used for home heating or industrial production, it is excellent."
"Freshly mined coal contains certain impurities such as dust and gangue."
"If used directly, it will not only cause the coal combustion efficiency to be greatly reduced, but also produce harmful substances during the combustion process, causing pollution to the environment."
"Through the water washing method, the dust in the raw coal can be effectively taken away, and the coal and gangue can be separated by shaking it up and down, thus obtaining relatively pure coal."
"There is a difference in the density of coal and gangue. If they are put together in running water and tossed up and down, the coal will float on the top and the gangue will sink below. In this way, the coal and gangue can be separated well.
"
Hu Changan also tried his best.
After all, there were no large-scale mechanical facilities in ancient times, and coal could only be initially purified through this primitive manual method.
After hearing what Hu Changan said, everyone felt a little confused.
This may sound reasonable, but how can you prove that it is true?
Everyone had only seen people cutting down firewood and using it as fuel, but they had never seen people using this black stuff as fuel.
Is this weird thing possible?
And is the washed coal really better than the unwashed coal?
Looking at the confused eyes of everyone, Hu Changan smiled slightly.
Hearing is false, seeing is believing. Now that I have some free time, let him show it to everyone.
The wind in Yingtian City in autumn was very strong, and soon the layer of wet coal washed out by the water showed signs of drying.
Hu Changan ordered the supervisor to bring a fire stick, took out a small pile of washed coal and unwashed coal, and lit them respectively.
At first, there was no movement between the two piles of coal.
But as time passed, everyone saw that the insides of the two piles of coal actually erupted with red light.
Someone came up curiously and wanted to touch it, and was immediately shocked by the heat.
Could this be fire?
Hu Changan looked at everyone's confused eyes, smiled, picked up a branch from the ground and put it into the black and red coal pile.
When the branch was pulled out, a flame suddenly appeared on the branch.
When everyone saw this, they couldn't help but be shocked.
Oh my god, it’s really fire!
This shows that this dark coal can indeed be used as a fuel!
Things that were not worth mentioning in the eyes of everyone now seem to shine brightly.
The young master is indeed amazing!
This kind of fuel was actually discovered by the young master first!
excellent!
Just as everyone was exchanging shocked looks, Hu Changan smiled again and said, "Take a closer look, what is the difference between these two fires?"
Everyone observed carefully for a moment and found the difference.
I saw that the smoke produced by the burning of the pile of unwashed coal was obviously relatively large.
Someone curiously came forward to smell it, and was immediately choked and coughed repeatedly.
Although the pile of washed coal also contained smoke, the smoke was obviously smaller than that of the unwashed pile.
Everyone looked at Hu Changan and couldn't help but marvel.
What is going on in the young master’s mind? How come he can even come up with such an awesome idea?
They didn't know that these things could be used as fuel, so the young master knew how to purify them.
As expected of a young master, he is better than these rough guys!
Those who had ridiculed Hu Changan before were so ashamed that they felt ashamed.
He couldn't understand what the young master was doing. He was simply too stupid.
A young master with such a great talent must have his own reasons for doing things!
Everyone looked at Hu Changan with shock and admiration.
Hu Changan smiled slightly and ordered someone to bring a sack of small dustpans and distributed them to everyone one by one: "Everyone, could you please wash the raw coal mined during the day into coal, then put it here to dry in the open air, and then put it in a frame and stack it
, I will send people to transport the coal away when the time comes."
In fact, Hu Changan wanted to make briquettes directly here, but the current steel production is too low to make briquette molds.
Hu Changan had no choice but to give priority to the Ministry of Industry and increase steel production first.
After listening to Hu Changan's words, everyone responded quickly.
After this experience, Hu Changan's image in their hearts grew taller and taller.
In the eyes of these workers, Hu Changan is simply the living version of Lu Ban.
After arranging the work on the coal side, Hu Changan left here with satisfaction.
With coal, the iron-making workshop of the Ministry of Industry can be put into operation! He will also go over to supervise it.
However, in the darkness, there is a pair of eyes, staring at this place.
...
Yingtian City, Li Shanchang Mansion.
After hearing the spies' report, Li Shanchang narrowed his eyes.
Good guy, I didn’t expect that before I could give Hu Changan a chance, Hu Changan would come to give me an excuse.
Recruiting villagers from nearby villages and distributing iron weapons to arm them is simply a complete rebellion.
Li Shanchang smiled slightly.
It seems that Hu Changan's good days may be coming to an end.
You must know that the first thing Zhu Yuanzhang hated was corrupt officials, and the second thing he hated was rebellion.
Who among the people sitting on the dragon's throne is not worried about the rebellion of his ministers?
Once the rebellion is successful, none of the previous royal family will be able to escape.
Those with better luck will be imprisoned until death.
Those who are less lucky will be executed directly.
If you are even less lucky, you may even be tortured to death.
Even if the rebellion fails, the people will be in ruins.
Therefore, no matter who is the ruler in the past dynasties, they must find ways to nip rebellion in the cradle.
Whether it is controlling the circulation of ironware among the people or prohibiting private casting of ironware, the purpose of piling up ironware is to prevent rebellion.
Once weapons and armor are found in a minister's home, no matter how powerful the minister is, he will be executed on the spot.
Even simply discovering weapons would be punishable by death, let alone directly recruiting villagers and giving them iron tools.
Li Shanchang had reasonable grounds to suspect that Hu Changan was secretly training his troops on the barren hills of Gaochun County.
Li Shanchang's eyes were cold.
Hu Changan, Hu Changan, there is a road to heaven but you don’t take it, and there is no door to hell but you come to it on your own.
Today is your death anniversary, Hu Changan! This chapter has been completed!
