In fact, if Fu Bin hadn't accidentally discovered a coal mine in Yifang County last time, Li Zexuan would not have thought of engaging in briquettes.
At least he won't do it in a short time!
But now that he has a big coal mine at home, he can't just take the charcoal inside instead of the coal, right? What a waste!
You must know that coal accounts for the vast majority of coal content in coal mines, and there is still relatively little charcoal that can be directly used for burning.
Based on the principle that waste is a great crime, Li Zexuan planned to invent a modern coal stove with a furnace and briquettes!
In modern times, on October 1, 1950, Guo Wende Family Industrial Co., Ltd. was established to produce the new fuel developed by Guo Wende-large honeycomb briquettes. In 1956, during the socialist transformation of capitalist industry and commerce, the large coal briquette processing industrial cooperative founded by Guo Wende also transformed from individual operation to state-owned. Since then, briquettes have become popular all over the country!
It is recorded in the data of that year that when burning ordinary coal, you need to shake out the ashes and add coal several times a day, but when burning honeycomb briquettes, you don’t need to light the fire every day, and you don’t need to turn on the fire and shake out the ashes frequently, so the annoying phenomenon of billowing black smoke and flying ashes Just completely gone.
A family of five or six people usually needs more than 300 kilograms per month to burn ordinary coal, but only more than 200 kilograms to burn honeycomb briquettes, which also saves the wood used to draw the coal. As a result of the promotion of briquettes in the capital in the first half of 1958, based on incomplete statistics in urban areas and some suburbs alone, more than 7,000 tons of firewood and more than 70,000 tons of coal were saved!
So in terms of resource conservation alone, Li Zexuan also felt that it was necessary to get out the briquettes!
Although the consumption of mineral resources in this era is far less than in modern times, save what you can! You have to leave some resources for future generations, right? In fact, the main reason is that Li Zexuan still misses his parents and family in his previous life. He doesn't want to think that more than a thousand years later, his family's era will run out of resources!
In addition to using the raw coal dug out from the coal mine to make briquettes, Li Zexuan also plans to use part of the coal to make coke.
The so-called raw coal coking refers to a process in which coking coal is heated to about 1,000 degrees Celsius (high-temperature carbonization) in isolation from air, and then produces coke, coke oven gas and other coking chemical products through thermal decomposition and coking.
From a technical point of view, there is nothing difficult.
The coke can be used as a reducing agent to make iron!
"Uncle Fu is joking! In that case, I won't delay your work here! We're not in a hurry about the furnace and molds. Let's get to the ironworks first~!"
Hearing Uncle Fu's praise, Li Zexuan was not proud, but felt a little sad in his heart, maybe because he thought of his parents in his previous life!
"Okay! In fact, both of these things are not complicated. I will ask someone to help the young master make a few first!"
Fu Bo nodded in response.
Li Zexuan didn't say anything else. He bowed his hands to Uncle Fu and left the west courtyard.
"Sister Wei'er, did you encounter any difficulties when making the telescope~?"
"Yes! Of course I have encountered it! For example, that idiot Xiao Ningzi is so clumsy every time that he breaks several of my lenses... Uh~! Chief Shanzhang, are you here?"
Li Zexuan originally planned to go to the office building of the workshop to sit for a while, but he did not expect to meet Xiao Yu'er and Mo Lingwei in the lobby on the first floor. Listening to the questions and answers of these two people, it seemed that they had something else. After Mo Lingwei noticed that he was coming, she quickly stopped talking and said hello.
"gentlemen!"
Xiao Yu'er had a pamphlet on her lap and a pencil in her hand. After Mo Lingwei said that Li Zexuan was coming, she put the pamphlet on the chair, stood up and said hello.
"Hmm! What are you doing~?"
Li Zexuan responded and asked with a smile.
Mo Lingwei turned to look at Xiao Yu'er and replied: "Shan Chief, I heard that there has been a big move in the workshop recently, and I was curious, so I came over to take a look! It doesn't matter if I can't help. If I can help, It’s better if you’re busy~! But I didn’t expect to meet Xiao Yu’er, so we chatted a little more!”
Li Zexuan couldn't help but said: "What? The Mo family also has research on iron smelting~?"
He knew that the Mohists were good at building institutions, but he really didn't know that the Mohists had research on the art of iron-making.
Mo Lingwei said proudly: "Of course! There are many records of iron smelting in the Mohist classics. I even made a lot of suggestions for improvement of the blast furnace built by Uncle Fu~!"
During the Spring and Autumn Period and the Warring States Period, China mastered the technology of smelting iron from iron ore and making steel from iron. The Mohists made these things as easy as drinking water!
And not only in iron smelting, the Mohists also made considerable research in sword casting. The Mo Xuejian, the personal sword of the Mohist giant, was extremely famous throughout Chinese history! So no matter what, it is impossible for the Mohists not to be proficient in the art of iron smelting.
"Haha~! Then I have to thank Miss Mo~!"
Li Zexuan saw that Mo Lingwei was speaking seriously, so he smiled and said politely.
Mo Lingwei waved her hand and said, "Hee hee! You're welcome, Master! I'm now a member of the academy, so it's time for me to contribute to the workshop!"
Li Zexuan smiled and looked at Li Yu again. Without waiting for him to ask, Li Yu took the initiative and said: "Chief, I heard a few days ago that Sister Wei'er has become a professor at Yanhuang Academy. I happened to meet her today, so I thought Writing her deeds in the newspaper can be regarded as a relief for our daughter’s family~! Just now I was asking Sister Wei’er to learn the details of how she made the telescope~!”
Li Zexuan was startled, thinking that this little fish's ideas are quite new. Isn't what she is doing now equivalent to those modern reporters interviewing celebrities and then using the interview content to make news? This little girl really has the talent to be a reporter, she can teach herself without any teacher~!
"Haha! That's it! Then you can continue chatting, but Xiaoyu'er, you have to be more careful when writing news. The making of telescopes is a secret of the academy and the court. Any technical things cannot be mentioned in the newspaper, otherwise it will There will be big trouble~!”
Li Zexuan has no objection to Xiao Yu'er setting up a role model for Tang Dynasty women like Mo Lingwei, but he must explain the principle issues clearly to you, Li Yu, in advance, because the technology of the telescope is too critical. If it falls into the hands of the enemy, , I don’t know how much trouble it will bring to Datang!
"Yes! I understand, sir! When the time comes, I will write out the news, and I will show it to you to read again~!"
Xiao Yu'er still knew the seriousness of the matter, and she quickly and solemnly responded after hearing this.
"OK!"
Li Zexuan nodded, looked at Mo Lingwei, and said: "Miss Mo, many of the things you know are related to the interests of the Tang Dynasty, so you must be careful in your words and deeds in the future, and must not divulge things to others that should not be divulged at will. !”
Mo Lingwei stuck out her tongue and said, "I know, Chief! I don't go out of the academy very often, so I won't reveal secrets!"
"Well, that's the best! Let's talk, I'll go up first!"
