Three Kingdoms

  Chapter 546 Pushing Beyond Physics

   Coal is a booster for modern industry.

   It is not that coal is better than charcoal, but that coal has the convenience that charcoal does not have.

  Charcoal needs to be felled, then the kiln is closed and smoldered, and finally the wood can be carbonized into charcoal, but the coal can be used when it is dug out, and it is not limited by the growth of wood.

   When a large amount of energy is needed, the advantages of coal are more obvious.

  But coal also has a more serious problem, that is, there are many impurities, especially sulfur. Desulfurization, Fei Qian really doesn’t know much, but I still remember that there was a reaction of sulfur calcification in the middle school chemistry class, so it was just roughly washed with water, smashed and dried, and mixed with a small amount of lime. It was found that there was still a little As a result, at least when burning, there is no smell of sulfur dioxide anymore...

  Of course, this kind of desulfurization is still far from meeting the requirements of steelmaking, so to make good steel, charcoal is still used at this stage.

   But in other respects, coal as fuel can play a considerable role.

Fei Qian has a lot of things now, so he can only talk to Huang Dou, and then Huang Dou can only fiddle with it himself in order to keep it secret. I lost a lot of weight.

  Huang Chengyan took the tongs and smashed the burnt briquettes in the brazier to pieces, and then said: "With this thing alone, Huang Dou can score another feat! But..."

  Huang Chengyan didn't finish his sentence, but his actions just now fully expressed his concerns.

   Although this thing is good, it is not suitable for mass sales of finished products. As long as anyone can get the original, they will imitate it more or less. Although some subtle additions may not be noticed, if it is only used for ordinary heating, cooking, etc. use, then even without these additives, there is not much difference...

  The technical content is too low to form a threshold.

Fei Qian also agrees with this point, unless he can take down the entire Bingzhou, including Shangdang and Taiyuan, close the Taihang Eight Paths, and control the entire Shanxi coal mine production area, otherwise this kind of technology that is not difficult will soon spread out.

  However, what Fei Qian pays attention to is that because of the emergence of this small substitute for heating in industrial physics, it will promote the entire engineering technology...

Fei Qian said: "I don't intend to sell this, but we use it ourselves. There is a complete river from Yong'an to Beiqu. On both sides of this river, there are many suitable places to build large-scale Workshops, and the fuel for most workshops..."

   Fei Qian pointed to the briquettes.

   Iron and steel technology is still not as good as high-quality charcoal unless it pushes coal one step further and turns it into coking coal, and then develops desulfurization technology.

But other projects that do not worry about impurities such as sulfur and phosphorus, such as preliminary rough embryo cement, high-sulfur but more colorful glass, red brick or cinder brick, gray tile or colored tile, etc. But can be a strong foundation for these products...

   Not much else to say, if all the wood and charcoal originally used for kiln and brick making were saved and used for iron smelting, how much steel would be produced?

   Also, direct heating.

  Humans, livestock heating in winter, and plants, even cooperate with the glass industry to develop greenhouse vegetables...

  The Little Ice Age is approaching, and coal will provide excellent protection for Fiji's entire northern army and livestock!

   This small physical change often brings more possibilities and more room for development!

   Needless to say other things, just if there are a little green vegetables and green leaves in winter, this is actually the same as the meaning of auspiciousness for the ruler!

  In the Han Dynasty, colored glaze was still very valuable, and vegetables grown in colored glaze houses were simply priceless...

   And the source of all these lies in this small, black coal.

With coal, Feiqian can at least guarantee that during the next Little Ice Age, at least in cities and towns, there will be no loss of various personnel and livestock due to climate reasons. Lead to regional large-scale felling of trees.

   In fact, there is another aspect of consideration, Fei Qian did not tell Huang Chengyan.

In order to keep warm in history, in the era when there was no large-scale use of coal, everyone's eyes were fixed on the trees. Excessive felling of trees not only caused vegetation destruction, water and soil erosion, but more importantly, directly The entire ecological environment has been changed, and the yellow sand has eroded. In the end, isn’t that how the remains of many ancient cities in the northwest were produced in later generations?

  The sooner coal is used on a large scale, it is actually the protection of vegetation.

Fei Qian said: "The vast Luliang Mountains are full of smoky light. There are layers of black coal slurry, and there are green ore deposits everywhere. Coal, lime, iron ore, clay, etc. are all available, and you can get them by bowing your head. My son-in-law wants to live here. To build a large workshop, on the one hand, water power can be used, and on the other hand, coal can be used to make all kinds of military equipment and folk utensils, and to research and develop glazed tiles, tiles, farming tools, etc. Wait until it is re-standardized and established, and write books, so that craftsmen can also be like Confucius and Mencius, and pass it on to future generations..."

  However, Feiqian's description of Bingzhou's future overall planning is enough to attract Huang Chengyan. Huang Chengyan listened, his eyes became brighter and brighter, but his expression became more and more entangled. After pondering for a long time, he only said one sentence with difficulty and had to think about it, so he drove Fei Qian away.

this…

   What do you mean?

  Although Fei Qian felt that the change in style of painting was too sudden, it was hard to say anything. After all, he was an elder, so he had to get up and leave first.

  Huang Chengyan sat alone in the study, the expression on his face fluctuating.

  The Huang family has established a foothold in Jingxiang for a hundred years. Most of the craftsmen and industries are located near Jingxiang. It is indeed not an easy task to transfer people to Bingzhou for a while.

  The situation described by Fei Qian is a place that all craftsmen, including Huang Chengyan, yearn for. There are water conservancy, minerals, fuel, places, and officials like Fei Qian who absolutely support craftsmen's research...

If he could be twenty years younger, no, perhaps only ten years younger, Huang Chengyan would go to Bingzhou with Feiqian to see it with his own eyes. If it was true, he might relocate resolutely, but now, Huang Chengyan had a hard time making a choice.

  It's really difficult...

   Liu Bei: I am in charge of the power over the world, and you are in charge of beauty.

   …

   Zhuge Liang thought for a while and said: Do you like older ones or younger ones?

   …

   Liu Bei looked at Zhuge who was 20 years younger than himself, and said righteously: I always like younger ones...

   …

   Years later, Zhuge looked at Jiang Wei, who was twenty years younger than himself, and said: I also like younger ones...
