Hu Changan ignored everyone's doubts and just ordered people to raise the two stoves at the same time.
One side is heated with charcoal, while the other side is heated with coal.
On the other side of the charcoal, a raging fire suddenly rose.
On the other hand, on the coal side, there was just a little bit of red inside, but no flames at all.
When everyone saw this, they couldn't help but murmur.
"Why is this coal burning without fire? It seems that the coal provided by Mr. Hu is not very good."
"Can it burn without fire? Isn't this Mr. Hu going crazy?"
"Although I am very impressed with Mr. Hu's operation last time, this time he is simply betting on our Ministry of Industry. This kind of thing can't even light a fire, and he claims it can be used like charcoal. It's simply ridiculous."
However, Hu Changan looked like an old god was present and just looked at the two stoves calmly.
Seeing that it was almost burning, Hu Changan randomly ordered someone to test the temperature on both sides.
When the man saw this, he was also very disapproving.
Do you still need to try this kind of thing? Anyone with a little bit of eyes can see it.
But now Hu Changan is the one in charge of this workshop after all, and his words cannot be violated in public.
So the man had to pretend to reach out to the two stoves, ready to test the temperature.
However, with this casual inspection, he was shocked.
The man tried it back and forth a few times without believing in evil, and then he said tremblingly: "Everyone, it seems that the temperature of the furnace burning coal is relatively high."
What?
Everyone immediately went into a rage.
The open flame wasn't even lit, but it was said that the temperature of coal was higher than that of charcoal?
I'm afraid that man was too eager to please Hu Chang'an, so he dared to tell lies with his eyes open?
Ma Shi was the first to not believe it. He rolled up his sleeves and walked to the two stoves, carefully feeling the temperature of the two stoves.
The stove burning charcoal was at a temperature he was familiar with, which was normal.
After all, Ma Shi is an old craftsman who has been working for decades. He knows very well what kind of temperature charcoal can produce when burning.
However, when he walked to the stove burning coal, his eyes widened in surprise.
The temperature does seem to be higher than that of the charcoal side?!
Ma Shi walked back and forth between the two stoves several times, and finally determined a fact.
Burning coal really is hotter than burning charcoal!
Ma Shi was stunned for a moment, and then shouted to everyone in surprise: "I've tried it, and the burning coal is really hot!"
This sound was like boiling water being poured into hot oil, completely frying the pot.
They don't have to believe the first person's words, but Ma Shi is a highly respected senior and there is no way he could lie!
Everyone was so shocked that they forgot even the most basic etiquette, and gathered around with a roar, carefully feeling the temperature of the two stoves.
At this time, facts speak louder than words, it is really that the furnace burning coal has a higher temperature!
Everyone couldn't help but feel a little hot.
This time, I'm afraid they are judging a gentleman with a villain's heart.
Who is Hu Changan? He is a rising star who is even more powerful than the old-timers like them, an absolute master of iron-making.
How could he promote bad things just because of a small grudge?
Facts have proved that as long as Hu Changan comes up with something, it is a good thing!
Everyone's admiration for Hu Changan couldn't help but deepen.
Looking at the fiery eyes of these craftsmen, Hu Changan also smiled slightly.
These craftsmen are quite simple. As long as they can come up with more advanced technology, they will be completely convinced by you!
Unlike the intrigues in the court, this made Hu Changan feel very relaxed.
Just when everyone was shocked, Ma Shi suddenly asked: "Shilang Hu, I wonder what the special substance you used on the day of the competition was. Is it this kind of mineral?"
As an old craftsman who was obsessed with iron-making, Ma Shi went to Hu Chang'an in private on the day he was defeated by Hu Chang'an and asked him for the secret recipe of iron-making.
However, Hu Changan just smiled at him at that time and said that it was not time yet and it was not convenient to reveal the specific information about that kind of ore to him.
Now when Hu Changan took out this new ore, Ma Shi immediately reacted.
Could this be the new mineral that Hu Changan mentioned at that time?
"Yes, the coke I placed in the furnace last time was formed by burning coal." Hu Changan smiled slightly and generously acknowledged Ma Shi's words.
Ma Shi was overjoyed when he heard this: "Shilang Hu, this new ore is simply a treasure for iron-making! It can be used as fuel and can be put into the furnace as a raw material for iron-making. One material has multiple uses!"
Looking at the burning coal, Ma Shi seemed to have seen a peerless beauty: "Shilang Hu, I wonder if the residue after burning coal can be directly thrown into the furnace as raw material for iron-making?"
When Hu Changan heard this, he smiled slightly: "Mr. Ma, your idea is very good, but it cannot be realized."
"When coal burns in the air, it combines with a type of particle in the air."
"Since coal has been combined with one type of particle, it naturally cannot combine with another type of particle during the iron-making process."
"So, coal burned in the air cannot speed up the progress of iron-making."
"But when coal burns in isolation from the air, it can no longer combine with the particles in the air. Only in this way can we obtain the pure reducing agent, which is the coke I put in the furnace last time."
"So when making coke, we have to let the coal burn without air."
"As long as the coal is placed in a small can that is insulated from the air when burning, this problem can be solved very well."
After hearing this, Ma Shi couldn't help but marveled: "Shilang Hu, I still think too simply! In the future, everything in my ironmaking workshop will depend on your care!"
When Hu Changan heard this, he also smiled modestly and said: "Everyone, there is no need to belittle yourselves. We are all the same people. As long as you master the physical and chemical knowledge I provided, you will definitely be able to improve the ironmaking process as easily as me in the future."
"Even my experience is not as good as yours. If you learn the knowledge I provide, you will definitely be better than me in the future!"
Everyone listened to Hu Changan's solemn words and couldn't help but breathe quickly.
Although they do not understand what physics and chemistry Hu Changan is talking about for the time being, this does not prevent them from thinking about the future.
Is it possible that one day in the future, they will be able to control the situation like Hu Shilang and directly double the iron output of the workshop while talking and laughing?
If this were true, that would be great!
Among them, Ma Shi was so moved that he almost burst into tears.
As a man who has been practicing hard all his life, how much he wants to learn the skills Hu Changan mentioned in his lifetime!
If you hear the truth in the morning, you will die in the evening! This chapter has been completed!
