Release that Witch

The boiler heating system is not a complicated thing. The essence is to heat the boiling water, then transfer the heat to the room through the pipeline, and then spread out by the radiator. The carrier of thermal energy can be water or water vapor. Roland uses the latter because the upper limit of steam temperature is higher and it is more convenient to circulate. As long as the boiler is kept burning, the steam pressure generated will automatically fill the small high temperature water droplets in every corner of the pipeline, even the pump is not needed.

Of course, steam heating is not without its shortcomings. The pipeline is always in a high-pressure environment. If the interface is not strong, it will easily leak or even explode. The high-pressure steam of two or three Baidus is only open to the skin, so the installation quality is higher. Anna's black wire welding can guarantee the strength of the interface, plus the coating of Soroya, this shortcoming can be reduced to a minimum.

At the same time, Roland also installed an automatic pressure reducing valve on the boiler. The mechanical principle is the same as that of 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 and decompress the exhaust gas.

The last piece of insurance was located at the junction of the boiler and the two main heating pipes. He asked Anna to engrave a number of grooves around the copper tube to reduce its strength, similar to a can. Even if the pressure valve does not open properly, the explosion will occur in the boiler room without harming the people in the room.

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

The heavy and heavy winter clothes disappeared, and the witches changed into the singles in the fall. Looking at the colorful girls talking and laughing in front of them, Roland felt that his work motivation had risen by five percentage points.

Of course, these facilities are all used to enjoy, or to build, an auxiliary device to create a better working environment.

What is to be done next is an important project related to the future of the West.

That is to achieve the artificial synthesis of ammonia, reduce the dependence on saltpeter, so that the production of chemical explosives is mentioned to a new height, so that it can meet the requirements of automatic shooting weapons.

If you can achieve this goal before the end of the winter, it will undoubtedly put a heavy bargaining chip on the planned spring offensive.

Roland called Camo Spoel and Ai Gesha to the office.

"How are you working together these days?" he asked with a smile. One person is the chief alchemist of Bianbu Town. Apart from the incomparable love of alchemy, he almost does not care about the feelings and opinions of others. One person is from the Witch Kingdom four hundred years ago. He has the pride of being a member of the highest research institution. Both of them are straight-forward. Putting together is like a gunpowder barrel. Roland is also often worried that they will have a dispute, but whether it is nitrifying gunpowder or synthetic ammonia, they must cooperate with each other, so they still have to ask the situation first. If they don't, they can only mediate.

“Very good,” Camo’s first sentence made Roland slightly surprised. “Miss Aisha’s ability has helped tremendously in chemical experiments. Now I have found a stable synthesis temperature for nitrification* glycerol, laboratory preparation. There is no problem, the possibility of further testing the industrial system is being tested... It can be said that there is no ice cup, and this can't be realized. Hey, because the work is too busy, I have not notified you." He paused, "by the way, if You want to ask this, can you let me go back to the lab now? I still have a lot to do."

Hey... is that the case? Roland looked at Ai Gesha, who nodded.

"Mr. Kaimo's knowledge is indeed different from ordinary people, especially the recognition of elements. It is quite similar to the Quest. Our cooperation is very enjoyable now. If you put it in Takira, he will certainly be absorbed by the Federation. ”

Is it straightforward to be more straightforward with straight sons? It seems that I am worried about one, and why is the chief alchemist's attitude towards the witch better than himself? It was simply sad... After Roland had a belly in his heart, he cleared his throat. "In this case, I am relieved. Call you, there is a new study to be handed over to you."

Upon hearing the word research, Camo immediately came to the spirit, "Please say."

"Before I said that there are many different kinds of gases in the air, and now is the time to use them." Roland summed up his thoughts. "According to "Elementary Chemistry," oxygen and nitrogen occupy the air. 99% of the ingredients, now I need to separate the two gases for chemical production."

Camo thought for a moment and replied, "What do you mean by using their different characteristics... for example, the difference between boiling point and melting point?"

“Yes,” Roland nodded with approval. “The air is condensed and then warmed up. The boiling point of nitrogen is lower than that of oxygen, so it will be fractionated from the liquid first. Since this temperature is far below the freezing point, the current Conventional means are difficult to do, so it must be done with the help of Aegis."

“Put the air into a liquid,” Kemo groaned with a beard. “It sounds very interesting.”

"If you lower the temperature further, they can even turn into solids, like ice," Roland smiled. This is definitely a scene that contemporary alchemists have never imagined. The seemingly imaginary gas can be held in the hand. The premise is to do antifreeze measures.

Ai Gesha wondered, "I also read some of the book, but when I freeze the air, I don't see it solidify into a variety of gases."

"Because they don't stratify when they are mixed together, it's hard to discern them with the naked eye," Roland explained. "The first thing that was ruled out was carbon dioxide, which has the highest freezing point, but the air content is extremely low, so You won't even notice the fine particles that solidify. The next step is oxygen and nitrogen, which blend perfectly together and appear light blue. If left unseparated, it looks like a pure substance. In fact Liquid nitrogen should be colorless."

"what should we do?"

“First prepare the fractionation vessel,” the prince tilted his mouth. “This is a big project.”

There is no doubt that it is not enough to rely on Aisha alone. The glass is prone to chipping during repeated changes in temperature, so containers containing liquid air can only be used in all-steel housings. This is not a difficult thing for Anna. The fully enclosed outer casing will not allow the change of liquid air to be observed when the temperature rises. Therefore, it is necessary to use the eye of the magical force of Sylvie to observe the inside of the container through the container, and then let the love Shake recorded the specific component of the magical consumption of liquid nitrogen boiling in order to obtain stable temperature parameters.

This preparation lasted for three days.

When the container was manufactured, Roland visited the chemical laboratory to instruct the town to conduct the first oxygen-nitrogen separation test.
