It looks pretty good.

The design of six feeding ports is easy to inlet and also facilitates evenly burning over the bottom of the pot.

This is very beneficial for burning.

The barrel-shaped design of the entire pot, as well as the height of only half a meter, is also to make the heat evenly, to make the coke well and thoroughly refined.

The design of the six-armed Nezha also plays a role. It doesn’t matter how much coal it saves, but the visual effect is very good.

Since a certain period of time, the surging flames in the combustion chamber have not stopped.

However, it takes a lot of time.

In modern industry, a kiln of cement only takes about half an hour to calcinate, but the coking starts in ten hours.

So, this burned until the next day.

After breakfast that day, when I came to see it again, the combustion chamber was much quieter.

The main reason is that it has been sprayed continuously for so long, and there is nothing to spray.

This also means that the kiln has been almost cooked, so water is prepared, fires are stopped, and materials are discharged.

The discharge port is on the side.

As the blocked earth and rocks moved away and the discharge port opened, the red coke instantly poured out with smoke.

"Stop it, all stand it!"

"Water, water, hurry!"

“…”

Simple and crude.

What kind of inert gas cooling, heat recovery, and if there is no such condition, just use water to nourish it.

In fact, even in modern society, many people are still using this cooling method.

Because it is simple enough and fast enough, the cooling effect can be achieved immediately.

But then again, it is not easy to produce the materials with this kind of earthen kiln design.

Is it more or less or less time?

When the water vapor was completely cooled down, I looked forward and saw that the coke obtained was quite uniform in size and was silver-gray.

Yongjia was also looking at it and asked, "Is it done?"

"It should be done." Chen Yuan nodded.

The dry distillation of coal includes low-temperature dry distillation, medium-temperature dry distillation, and high-temperature dry distillation. Only high-temperature dry distillation can produce coke silver-gray.

Coke used in the metallurgical industry is also obtained from high-temperature dry distillation.

After saying that, he ordered people to collect and load the truck. At the same time, seal the discharge port, open the feed port, continue to add and distillate.

He and Yongjia went to the blacksmith shop with the cart that transported the coke.

The blacksmith shop did not start construction today. Instead, because of the greeting in advance, the entire furnace was cleaned up.

"What should I do now?"

After being busy for so long, it was finally time to accept the results. At this moment, Yongjia couldn't help but feel a little excited.

Chen Yuanyi, but he was quite calm. He smiled and said, "I just changed the fuel, I will do whatever I want."

After saying that, he nodded to Lao Zhang and his son, indicating that he could start.

The father and son burned a small pile of flammable charcoal outside the furnace.

The charcoal is lit, transferred to the furnace, added more charcoal and blasted, and waited until it was completely ignited, spread out, one layer of coke, another layer of ore, alternately laying.

Until the entire furnace is full.

Then pull the bellows and blow the air.

The effect is still very significant.

As a special fuel for metallurgy, coke produced by high-temperature distillation will release more heat and bring higher temperatures when burned.

The direct consequence of this is that as the bellows push and pull, the originally dark furnace quickly turns red and the heat waves rise rapidly.

This shocked Lao Zhang, who had been fighting for a lifetime, and said: "Marty, why is this coke, so amazing?"

“Amazing?”

Chen Yuan didn't feel anything at all.

He knew that the speed and effect of this burning were better than the coal that was added with water and mud last time.

But, isn't that supposed?

If he couldn't even compare with the last time's effect, wouldn't he be so lonely?

Lao Zhang said, "It's amazing, this fire is too fierce. If nothing unexpected happens, this furnace of ore will be burned into water."

Burn into water and melt it.

At present, the current conditions are usually only a dedicated iron smelting blast furnace, a large amount of charcoal is used as fuel, and a large bellows can provide air supply and release energy.

For example, the small iron furnace in front of us can also smelite, but it is usually smelite.

It is just that iron ore is thrown in and melted into a big lump of iron and melted into water, which is impossible.

But the fact is that this furnace of iron ore was indeed burned.

As the bellows continue to pull, the fire becomes bigger and bigger and the heat wave becomes more and more violent.

In sight, the ore and coke in the furnace quickly turned from its original fiery red to burning eyes, and it was almost impossible to look directly at it. The entire material bed seemed to collapse, and its height was constantly decreasing.

At one moment, someone suddenly exclaimed: "Look, water is coming out from below."

Chen Yuan looked at it and said, "Damn it, it's really water, it's like a sticky water, like lava, and it's so red that it's white.

Yongjia was so excited that he grabbed his arm and said excitedly: "It's out of water, Chen Yuan, you see, it's out of water..."

"Yeah, I know, the problem is, we are not prepared for this!"

It was a bit unexpected.

I just wanted to remove sulfur so that the iron refined is not so crispy. I just burn it into molten iron, I never thought about it!

Moreover, the word "water" is really bad.

Especially when water comes out from below, I always feel strange when I hear it.

Yongjia's little face turned red: "When it comes out, it's water. What preparations are needed? Could it be that you can use a pot to continue?"

"What about that?"

"How did the bronze cauldron be cast? Isn't it because of the copper juice poured into the mold with something?"

After thinking about it, Chen Yuan was still not confused about the words and said seriously.

Yongjia thought: "That's right, it's actually the same. When copper ore is burned into water and copper juice, you can cast various bronze utensils. When iron ore is burned into water and iron juice, you can also cast various utensils.

But by comparison, copper ore is easy to burn into water, while iron ore is difficult to burn into water.

Then, in this case, wouldn’t we still have to build a special iron smelting furnace?”

It's indeed the same.

It is true that copper and iron are two different things. It is essentially the same thing.

When people in ancient times learned to smelify copper and cast bronze utensils, it meant that they actually learned to smelify iron.

However, because of the properties of matter itself, smelting iron is much more difficult than smelting copper.

Originally, Yongjia didn't think so much about it, so she wanted to build a small blacksmith shop, beat horseshoes, and make some farm tools. She was really bored and beat swords.

After all, this life without worries about food and clothing is really boring, so you have to have some fun.

Of course, it is too early to say this now.

In short, the iron ore has been burned, but how well the sulfur is removed, it is still unknown whether the iron refined is still crisp or not.

No matter how you have to wait until the final result comes out before talking.

Moreover, in modern blast furnace iron smelting, in addition to coke and iron ore, limestone is also required.

Limestone decomposes into calcium oxide and carbon dioxide at high temperatures, among which calcium oxide can further remove sulfur and some other impurities, while carbon dioxide can form carbon monoxide with carbon, thereby more effectively reducing the iron in iron ore.

This is just that I didn't expect it to be so indifferent.

If you know in advance, you can burn it, and limestone will definitely be arranged.
