Release that Witch - Chapter 379

[Chapter 377]

The boiler heating system is not a complicated thing. Its essence is to heat boiling water, then transport the heat energy to the room through pipes, and then diffuse it through the radiator.

The carrier of heat energy can be water or water vapor. The reason why Roland uses the latter is because the upper limit of steam temperature is higher and it is more convenient to circulate.

As long as the boiler is fired continuously, the steam pressure generated will automatically fill every corner of the pipeline with tiny high-temperature water droplets, even without a water pump.

Of course, steam heating is not without disadvantages. The pipeline is always in a high-pressure environment. If the connection is not strong, it is easy to leak or even explode. As long as the high-pressure steam of two or three hundred degrees hits, the skin will be torn. Therefore, the installation quality is higher.

Anna’s black wire welding can ensure the strength of the interface, and with Soraya’s coating, this shortcoming can undoubtedly be minimized.

At the same time, Roland also installed an automatic decompression valve on the boiler. Its mechanical principle is the same as the centrifugal governor on the steam engine. When the pressure in the furnace is too high, the high-speed rotating flywheel will pull up the valve to exhaust and decompress.

The last insurance is located where the boiler is connected to the two main heating pipes. He asked Anna to carve several grooves around the copper pipe to reduce its strength, similar to a can.

Even if the pressure valve fails to open properly, the explosion will occur in the boiler room without endangering the people in the room.

When the heating system was turned on, the scene in the castle changed completely.

The heavy and thick winter clothes disappeared, and the witches changed into autumn single clothes again. Seeing the colorful girls chatting and laughing in front of him, Roland felt that his work motivation had risen by five percentage points invisibly.

Of course, these facilities are for enjoyment, or auxiliary equipment built to create a better working environment.

The next thing to do is an important project related to the future of the Western Territory.

That is to realize the artificial synthesis of ammonia, reduce the dependence on saltpeter, and thus raise the production of chemical explosives to a new level, so that it can meet the requirements required by automatic shooting weapons.

If this goal can be achieved before the end of winter, it will undoubtedly give the planned spring offensive a heavy bargaining chip.

Roland called Kymer Struer and Agatha to the office.

“How are you working together these days?” he asked with a smile.

One is the chief alchemist of Border Town. Apart from his great love for alchemy, he hardly cares about other people’s feelings and opinions.

One came from the Kingdom of Witches four hundred years ago and had the pride of being a member of the highest research institution, the Quest Society. Both of them were straightforward, and together they were like a powder keg that could explode at the touch of a button.

Roland was also often worried about whether they would have a dispute, but whether it was nitrated gunpowder or synthetic ammonia, both of them had to work together, so he still had to ask about the situation first, and if there was a disagreement, he could only mediate.

“Very good,” Kaimo’s first words surprised Roland a little, “Miss Agatha’s ability is of great help to chemical experiments. Now I have found the stable synthesis temperature of nitroglycerin, which can be produced in the laboratory. There is no problem, and the possibility of industrial production is being further tested… It can be said that without ice cups, none of this can be realized. Oh, because I am too busy with work, I did not inform you.” He paused, “By the way, if You want to inquire about this, can you let me go back to the laboratory now, I still have a lot to do.”

Uh… is that so?

Roland looked at Agatha, who nodded.

“Mr. Kemo’s knowledge is indeed different from ordinary people, especially the cognition of elements, which is quite similar to the Quest Society. Our cooperation is very happy now. If it is placed in Taquila, he will definitely be absorbed by the Federation. ”

Could it be that straight-tempered and straight-tempered people are easier to get along with?

It seems that I was worried for nothing, and why did the chief alchemist treat witches better than himself?

It’s so sad… Roland cleared his throat after slandering in his heart, “Since that’s the case, I’m relieved. I called you here because there is a new study for you.”

Hearing the word research Kaymo immediately became energetic, “Please tell me.”

“I said before that there are many different gases in the air, and now is the time to use them.” Roland roughly explained his thoughts, “According to “Elementary Chemistry”, oxygen and nitrogen account for 99% of the air. Now I need to separate these two gases for chemical production.”

Kyle thought for a moment and replied, “You mean, use their different characteristics…such as different boiling points and melting points to separate?

” The boiling point is lower than that of oxygen, so it will be fractionated from the liquid first. Since this temperature is far lower than the freezing point, it is difficult to achieve it with current conventional methods, so it must be achieved with the help of Agatha’s ability.”

” Turning air into a liquid,” Kaimo stroked his beard and grinned, “sounds very interesting.”

“If the temperature is further lowered, they can even become solid, just like ice cubes,” Roland smiled.

This is definitely a scene that contemporary alchemists have never imagined. The seemingly illusory gas can also be held in the hand-provided that antifreeze measures are taken.

Agatha wondered, “I’ve also read some of that book, but when I froze the air, I didn’t see it solidify into a variety of gases.

” It’s hard to tell with the naked eye, UU Reading www.sonicmtl.com “Roland explained, “The first thing to be eliminated is carbon dioxide, which has the highest freezing point relatively, but its content in the air is extremely low, so you won’t even notice it freezes. The tiny particles that come out. The next thing is oxygen and nitrogen, which blend perfectly together and have a light blue color that, if not separated, looks like a pure substance. In fact, liquid nitrogen should be colorless ”

“What should we do?”

“Prepare the fractionation vessel first,” the prince said with the corners of his lips curled up, “This is a big project.”

There is no doubt that Agatha alone is not enough.

Glass is easy to break when the temperature changes repeatedly, so the container holding liquid air can only use an all-steel shell.

This is not a difficult task for Anna, but the fully enclosed shell will make it impossible to observe the changes in the liquid air when the temperature rises, so it is necessary to use Sylvie’s magic eye to observe the scene inside the container, and let Aegor Sha recorded the specific amount of magic power consumed when the liquid nitrogen boiled, in order to obtain the temperature parameters for stable production.

This preparation lasted three days.

When the container was manufactured, Roland visited the chemical laboratory in person to guide the town to carry out the first experiment of oxygen and nitrogen separation.
