Otaku Engineer in Great Tang Dynasty

In fact, if it wasn't for Fu Bin's accidental discovery of a coal mine in Yifang County last time, Li Zexuan would not have thought of engaging in honeycomb coal.

At least he won't do it any time soon!

But now that his family has a big coal mine, he can't just take the charcoal inside, but not the coal inside, right? What a waste!

It should be known that the content of coal in coal mines accounts for the vast majority, and the kind of charcoal that can be directly used for burning is still relatively small.

Based on the principle that waste is a great crime, Li Zexuan planned to fiddle with the modern coal stove with a hearth and honeycomb briquettes!

In modern times, on October 1, 1950, Guo Wende Family Industrial Society was established to produce a new type of fuel developed by Guo Wende - honeycomb-shaped briquettes. In 1956, in the socialist transformation of capitalist industry and commerce, the large coal briquettes processing industrial society founded by Guo Wende also changed from self-employed to state-owned, and honeycomb briquettes have been popular throughout the country since then!

It is recorded in the documents of that year that burning ordinary coal blocks requires shaking ashes and adding coal several times a day, while burning honeycomb briquettes does not need to be fired every day, and it does not need to be fired and shaken frequently, so the annoying phenomenon of black smoke billowing and flying ashes completely gone.

A family of five or six people generally needs more than 300 catties to burn ordinary coal blocks every month, but only 200 catties to burn honeycomb coal, which also saves the wood for coal. In the first half of 1958 in the capital, the result of the promotion of honeycomb coal was that only the incomplete statistics of urban areas and some suburban areas saved more than 7,000 tons of firewood and 70,000 tons of coal!

Therefore, from the perspective of saving resources, Li Zexuan also felt that it was necessary to get the briquettes out!

Although the consumption of mineral resources in this era is far less than that of modern times, it can save a little if you can save a little! Gotta keep 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 more than a thousand years from now, the era in which his family lives will have no resources!

In addition to using raw coal dug out of coal mines to make honeycomb, Li Zexuan also plans to use part of the coal to make coke.

The so-called raw coal coking refers to the process in which coking coal is heated to about 1,000 degrees Celsius (high temperature dry distillation) under the condition of isolated air, and coke, coke oven gas and other coking chemical products are produced through thermal decomposition and coking.

Technically, there is nothing difficult.

The trained coke can be used as a reducing agent to make iron!

"Uncle Fu is joking! That's the case, I won't delay your work here! The furnace and the mold are not in a hurry, let's come to the ironworks first~!"

Hearing Uncle Fu's praise, Li Zexuan was not complacent, but felt a little sad in his heart, perhaps because he thought of his parents in his previous life!

"That's fine! In fact, these two things are not complicated. I will ask someone to help the young master make a few first!"

Forber nodded.

Li Zexuan didn't say anything, he bowed his hands to Uncle Fu, and left the west yard.

"Sister Wei'er, did you encounter any difficulties when you were making the telescope~?"

"Yeah! Of course I have encountered it! For example, Xiao Ningzi's idiot, who is clumsy every time, has broken several of my lenses in total... uh~! Chief, are you here?"

Li Zexuan originally planned to go to the office building of the workshop to sit for a while, but he didn't expect to meet Xiaoyuer and Mo Lingwei in the lobby on the first floor. Hearing their questions and answers, it seemed to have a different meaning. After Mo Lingwei found him coming, she quickly stopped the topic and said hello.

"gentlemen!"

Xiaoyuer had a booklet on her lap and a pencil in her hand. After hearing Mo Lingwei say that Li Zexuan was coming, she put the booklet on the chair and stood up to say hello.

"Well! What are you doing~?"

Li Zexuan responded and asked with a smile.

Mo Lingwei turned her head and glanced at Xiao Yu'er, and replied, "Shan Chief, I heard that there is 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 you, if you can help It's even better if you're busy~! I just didn't expect to meet Xiao Yu'er, so we chatted a few more words!"

Li Zexuan couldn't help but said, "What? The Mo family also has researches on iron making~?"

He knew that the Mo family was good at building institutions, but he really didn't know that the Mo family still had research on the art of iron making.

Mo Lingwei said proudly: "Of course! There are many records of iron smelting in the ancient books of the Mo family. I have also suggested a lot of improvement suggestions for the blast furnace that Fu Bo is building now~!"

During the Spring and Autumn Period and the Warring States Period, China had 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, but also in the aspect of sword casting. So no matter what, it is impossible for the Mo family not to be proficient in the art of iron smelting.

"Haha~! Then I have to thank Miss Mo~!"

Seeing that Mo Lingwei said something serious, Li Zexuan smiled politely.

Mo Lingwei waved her hands and said, "Hee hee! You're welcome! I'm a member of the academy now, so I should contribute to the workshop!"

Li Zexuan smiled and looked at Li Yu again, without waiting for him to ask, Li Yu took the initiative to say: "Shan Chang, I heard that Sister Wei'er has become a professor of Yanhuang Academy a few days ago. I happened to meet her today, and I thought about it. Writing her deeds in the newspaper can be regarded as a fight for our daughter's family~! I was just asking Sister Weier about the details of her making a telescope~!"

Li Zexuan was stunned, thinking that this little fish's thoughts were quite trendy.

Isn't it the modern equivalent of journalists who interview celebrities and then use the interviews for news? This little girl really has the talent to be a reporter, she will learn without a teacher~!

"Haha! That's it! Then let's talk, but Xiaoyuer, you have to be careful when you write the news. The production of the telescope is a secret of the academy and the court. Any technical things cannot be mentioned in the newspapers, otherwise it will be There will be big trouble~!"

Li Zexuan has no objection to Xiaoyuer to set up a typical Tang Dynasty woman like Mo Lingwei, but he must explain to you Li Yu clearly 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!

"Yeah! I see, sir! I'll write the news at that time, and I'll show it to you to have a look~!"

Xiaoyuer still knew the seriousness of the matter, she heard the words quickly and solemnly replied.

"Row!"

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 cautious in your words and deeds in the future, and you must not disclose things that should not be disclosed to others at will. !"

Mo Lingwei stuck out her tongue and said, "Got it, Chief! I don't usually go out of the academy, so I won't reveal secrets!"

"Well, that's the best! Let's talk, I'll go up first!"
