In fact, if it weren't for Fubin's chance to discover 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 anytime soon!

But now that he has a big coal mine at home, he can't just take the charcoal in it, but not the coal in it, right? What a waste of that!

You must know that the content of coal in coal mines accounts for the vast majority, and the kind of charcoal that can be directly used for less is still relatively small.

In line with the principle that waste is a great crime, Li Zexuan planned to make the modern coal stove with a hearth and honeycomb briquettes!

In modern times, on October 1, 1950, Guo Wende Family Industry Co., Ltd. was established to produce a new type of fuel developed by Guo Wende - honeycomb briquettes. In 1956, in the socialist transformation of capitalist industry and commerce, the large briquette processing industrial company founded by Guo Wende also changed from self-employed to state-owned, and honeycomb coal began to become popular all over the country!

It is recorded in the data of that year that it is necessary to shake the ashes and add coal several times a day to burn ordinary coal, and burning honeycomb coal does not need to make a fire every day, and there is no need to burn and shake the ashes frequently, so the annoying phenomenon of black smoke billowing furnace ashes is completely gone.

A family of five or six people generally needs more than 300 catties of ordinary coal every month, while it only needs more than 200 catties to burn honeycomb coal, and it also saves wood for coal introduction. As a result of the promotion of honeycomb coal in the capital in the first half of 1958, incomplete statistics in urban areas and some suburbs alone saved more than 7,000 tons of firewood and more than 70,000 tons of coal!

Therefore, just from the perspective of saving resources, Li Zexuan also feels that it is necessary to get out the honeycomb coal!

Although the consumption of mineral resources in this era is far less than that of modern times, you can save a little if you can save a little! You have to leave some resources for future generations, don't you? In fact, the main thing is that Li Zexuan is still thinking about his parents and family in his previous life, and he doesn't want to be more than a thousand years later, the era in which his family lives has no resources!

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

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

In terms of craftsmanship, there is nothing difficult.

The coke can be used as a reducing agent for refining the body!

Fauber laughed! In that case, I won't delay your work here! I'm not in a hurry about the furnace and mold, so let's come to the ironworks first~! ”

Hearing Fu Bo's praise, Li Zexuan was not proud, but felt a trace of sadness 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 the young master to make a few first! ”

Fauber nodded in response.

Li Zexuan didn't say anything more, he arched his hand towards Fu Bo, and walked out of the courtyard to the west.

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

"Hmmm! Of course there are! For example, Xiao Ningzi, that stupid person, is clumsy every time, and breaks several of my lenses.... Belch~! Mountain 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 Xiao Yu'er and Mo Lingwei in the hall on the first floor. After Mo Lingwei found out that he was coming, she hurriedly stopped the topic and said hello.

"Sir!"

Xiao Yu'er had a booklet on her lap and a pencil in her hand, but after hearing Mo Lingwei say that Li Zexuan was coming, she put the booklet on the chair and got up to greet her.

"Hmmm! What are you guys doing here~? ”

Li Zexuan answered and asked with a smile.

Mo Lingwei turned her head to look at Xiao Yu'er and replied, "Mountain Chief, I heard that there has been a big move here in the workshop recently, and I was curious, so I came over to take a look!" It doesn't matter if you can't help, if you can help, it's even better~! It's just that I didn't expect to meet Xiaoyu'er, so I chatted a few more words! ”

Li Zexuan couldn't help but say, "What? The Mohists also have research on ironmaking~? ”

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

Mo Lingwei said proudly: "Of course! There are a lot of records of iron smelting in the classics of the Mo family, and I have put forward a lot of suggestions for improvement in the blast furnace that Fu Bo is building now~! ”

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, and the Mohists made these things as easy as drinking water!

And not only in iron smelting, the Mo family is also quite researched in sword casting, and the Mo family giant's personal saber Mo Xue Sword is extremely famous in the entire Chinese history! So no matter what you say, it is impossible for the Mo family not to be proficient in the art of iron smelting.

"Hehe~! That's a lot of thanks to Miss Mo~! ”

Li Zexuan saw that Mo Lingwei said something serious, so he smiled politely.

Mo Lingwei waved her hand and said, "Hehe! You're welcome! I'm a member of the academy now, so I should do my part for the workshop! ”

Li Zexuan smiled, looked at Li Yu again, and without waiting for him to ask, Li Yu took the initiative to say: "Mountain Chief, I heard a few days ago that Sister Wei'er became a professor at Yanhuang Academy, and I happened to meet her today, so I thought about writing her deeds in the newspaper, which can be regarded as fighting for our daughter's family~!" Just now I was asking Sister Wei'er about the details of her making a telescope~! ”

Li Zexuan was stunned, and said in his heart, this little fish's thinking is quite trendy, isn't what she is doing now equivalent to those modern reporters interviewing celebrities and then using the interview content for news? This little girl really has the talent to be a reporter, and she will be self-taught~!

"Haha! I see! Then you can continue to talk, but Xiao Yu'er, you have to pay attention when you write the news, the production of the telescope is a secret of the academy and the imperial court, and any technical things cannot be mentioned in the newspaper, otherwise there will be big trouble~! ”

Li Zexuan does not object to Xiao Yu'er to set up a typical example of a Tang woman like Mo Lingwei, but in terms of principle, he must explain clearly to Li Yu in advance, because the technology of the telescope is too critical, and if it falls into the hands of the enemy, I don't know how much trouble it will bring to Datang!

"Hmmm! I see, sir! When the time comes, I will write out this news, and I will show you a look~! ”

Xiao Yu'er still knew the seriousness of the matter, and she hurriedly and solemnly replied when she heard the words.

"Okay!"

Li Zexuan nodded, looked at Mo Lingwei, and said, "Miss Mo, many of the things you know are related to the interests of Datang, so you have to be cautious in your words and deeds in the future, and you must not leak things that should not be leaked to others at will!" ”

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

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