Daming Military Empire

Chapter 573 Diesel and Kerosene

After visiting the third floor, Zhu Cijiong was full of expectations, because the extract on the third floor was already in liquid state, and the next step should be fuel, which is the focus of future development. If there is fuel, there is hope for internal combustion engines. With the internal combustion engine, the speed of trains and ships will be greatly improved, and cars will no longer be a dream!
With excitement, Zhu Cijiong quickly climbed up the steps leading to the fourth floor. He couldn't wait to see if Song Yingxing had really refined diesel, kerosene, and gasoline.

The temperature on the fourth floor is a little lower than that on the third floor, and it has dropped to a level that ordinary people can bear, and the air is still full of humidity.

This floor looks similar to the first three floors from the outside. There is still a blast furnace in the middle, unlike a blast furnace, and the room is not like a giant room. There is also an opening like a door opening leading into it, and there are also two people standing beside the opening. It seems that this outer layer It's just for heat insulation, Song Yingxing didn't put too much thought into it, so they all look the same.

So what's it like inside?Zhu Cijiong poked his head into the doorway curiously and saw that it was still a huge iron pot. However, this iron pot was already a bit like a common boiler, but it was much bigger.

After feeling the humidity in the air, Zhu Cijiong turned around and asked, "Is this layer heated by steam?"

Song Yingxing nodded and said: "Yes, your majesty, because at the beginning, the things refined at several temperatures were too easy to catch fire. After many experiments, Wei Chen felt that it was safer to heat with steam, so he heated them with oil storage tanks and coal. A steam pot was added between the fires, and the coal fire was used to heat the steam first, and then the steam was used to heat the oil."

Sure enough, fuel is flammable and explosive. It is too dangerous to heat it directly with fire. The steam in the interlayer is safe. From Song Yingxing's description, from this layer, the fuel should be extracted. Zhu Cijiong can't wait He said: "What about the things extracted from this layer? Take a look."

Song Yingxing heard the words, and quickly asked the person on duty on this floor to go to the storage room to get it.

Soon, the guard on this floor brought over an iron bucket, the contents of which were obviously liquid, and should be fuel.

Zhu Cijiong took a closer look, and found that the gray was blackish, a bit like heavy oil. He dipped a little more, put it in front of his nose and smelled it carefully, and it turned out to be the smell of diesel!
He understood that it should be a mixture of heavy oil and diesel.

Heavy oil is generally used on large generator sets and large ocean-going ships, and it needs to be heated before it can be used, while diesel oil can be used on ordinary trains, cars and small ships, and can be used at room temperature. There is a difference between these two types of oil. How to explain it?
Looking at Song Yingxing's eager eyes, Zhu Cijiong sorted out his thoughts, and then pointed out: "This oil is not pure, so it must be separated into two kinds of oils, one is slightly yellow, transparent oil like vegetable oil , is called diesel oil, and the rest is slightly black, and the sticky one is called heavy oil. You can send diesel oil directly to Wang Zheng to let him study new car power. For heavy oil, you send it to Xu Fuyuan and Xia Yunyi to see if they have it. way to make a bigger generator."

Hearing this, Song Yingxing was so excited that he finally understood the purpose of the emperor asking him to study oil refining. These things are so useful when extracted, they are just like steam engines. They are the foundation of other industries. Being able to engage in such important Research is simply a great honor, he nodded heavily and said: "I understand."

Zhu Cijiong nodded, stepped up the steps first, and walked to the fifth floor.

Before reaching the fifth floor, a strong smell of kerosene came over us.

Kerosene, definitely kerosene, Zhu Cijiong couldn't help speeding up his pace to the fifth floor.

The temperature on the fifth floor was much lower than that on the fourth floor, and the air was still humid. Needless to say, Song Yingxing used steam heating again.

Needless to say, the shape in the middle of the fifth floor is the same as that of the first four floors, but there is a big difference inside, except for a large iron can, there is a small iron can connected to the big iron can with a pipe. The height difference feels like distilled wine.

This time, Zhu Cijiong felt that the temperature inside was not very high, so he really wanted to go in and have a look, but just as he was about to go in, the two people at the first door stretched out their hands to stop him, and looked at Song Yingxing in embarrassment.

Seeing this, Jin Yiwei and Dongchang masters on both sides pressed their hands to the handle of the knife one after another. As long as the emperor speaks, they will kill people!
Zhu Cijiong looked back at Song Yingxing inexplicably, couldn't he just go in here?

Song Yingxing didn't know if it was hot or something, a big pile burst out on his forehead, he explained in panic: "The emperor calms down, it's very dangerous inside, my minister has stipulated that those who have not been trained are not allowed to enter."

Hearing this, Zhu Cijiong immediately shrank back, not because he was afraid of danger, but mainly because he wanted to abide by the regulations of the experimental field. He knew that many experiments were very dangerous. If he didn’t follow the regulations, he would lose his life, or even destroy the entire experiment. field is possible.

However, he really couldn't see any danger here, so he couldn't help asking curiously: "Isn't this a hot spot, what danger is there?"

Seeing that the emperor retracted, Song Yingxing sighed, and carefully explained: "Your Majesty, it is indeed very dangerous inside, because the steam inside is not ordinary steam. When the experiment was refining oil, direct heating happened several times. The accident burned several people, so we thought about using steam to heat the oil first. However, after many experiments, we found that if we opened the steam to burn, the temperature could not go up, so we sealed the steam and continued. Burn, the temperature can rise."

Zhu Cijiong didn't understand anymore. Isn't it because the temperature is higher? He asked puzzledly: "Isn't it going to be fine if you don't touch it? Are there other dangers?"

Song Yingxing nodded in fear and said: "Yes, when I first started experimenting with sealing and heating steam, the jar was not sealed, and the steam sprayed out from a crack after heating for a while, directly breaking a person's hand! So Only then did Wei Chen stipulate that idlers and others are not allowed to enter the place where the steam is sealed and heated."

Zhu Cijiong was taken aback when he heard the words, and only now did he realize that it was high-pressure steam, and that thing was indeed dangerous, so he nodded and said, "Well, you are doing the right thing, I won't go in, put the Take a look at the things extracted from this layer."

Song Yingxing heard the words and ordered that the guards on this floor will soon bring a porcelain jar, which looks like a jar for wine!
Zhu Cijiong asked in surprise: "Is this to prevent volatilization?"

Song Yingxing was also quite surprised when he heard the words: "Volatilization? The emperor's words are wonderful. Indeed, if you open it up, a lot of it will go down in a few days. It should be volatilization, that's why I let people use wine. The jar is sealed."

Hearing this, Zhu Cijiong nodded, stepped forward and removed the sandbags pressed from the jar, and smelled it lightly. It was indeed kerosene, and the kerosene inside was relatively clear.
