The boiler heating system is not a complicated thing, its essence is to heat the water, and then transmit the heat energy to the room through pipes, and then spread it out by the radiator. The carrier of thermal energy can be water or water vapor. Roland uses the latter because the upper limit of the steam temperature is higher and it is more convenient to circulate. As long as the boiler is continuously fired, the steam pressure generated will automatically fill every corner of the pipe with tiny high-temperature water droplets, even without the need for a pump.
Of course, water vapor heating is not without its shortcomings. The pipeline is always in a high-pressure environment. If the interface is not strong, it is easy to leak or even explode. As long as two or three hundred degrees of high-pressure steam is exposed, the skin will be cracked, so the installation quality is higher. Ana'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 set up an automatic pressure reducing valve on the boiler. Its 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 reduce the exhaust gas.
The last insurance was at the connection between the boiler and the two main heating pipes. He asked Anna to carve several grooves around the copper pipe to reduce its strength, similar to a soda can. Even when 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 in operation, the scene in the castle changed completely.
The heavy and thick winter clothes were gone, and the witches put on their autumn singles again. Seeing the colorful girls chatting and laughing in front of him Yan Yan, Roland felt that his work motivation had increased by five percentage points.
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 Region.
That is to realize the artificial synthesis of ammonia gas and reduce the dependence on saltpeter, thereby raising the production of chemical explosives to a whole new level, so that it can meet the requirements of automatic fire weapons.
If this can be achieved by the end of winter, it will undoubtedly give a heavy bargaining chip to the planned spring offensive.
Roland called Camer Strell and Agatha to the office.
"How have you been working together these days?" he asked with a smile. One of them is the chief alchemist of Border Town. Apart from his incomparable love for alchemy, he hardly cares about the feelings and opinions of others. One came from the witch kingdom 400 years ago, and had the pride of being a member of the highest research institute Quest Club. Roland is also often worried about whether they will have a dispute, but whether it is nitrification gunpowder or synthetic ammonia, the two must work together, so he still has to ask about the situation first. If there is a disagreement, he can only mediate.
"Very good," Roland was slightly surprised by Kemo's first sentence, "Miss Agatha's ability is very helpful for chemical experiments. Now I have found the stable synthesis temperature of nitroglycerin, which is prepared in the laboratory. No problem, the possibility of further testing the industrial method... Suffice to say, none of this would be possible without the ice cup. Oh, I didn't notify you because I was too busy with work." He paused, "By the way, if you I want to ask about this, can I go back to the lab now, I still have a lot of things 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 Club. Our cooperation is currently very happy. If it is put into Taquila, he will definitely be absorbed by the Federation. "
Are straight people and straight people easier to get along with? It seems that he is worried for a while, and why does the chief alchemist have a better attitude towards witches than himself? It's so sad... Roland cleared his throat after slandering in his heart, "Since that's the case, I'm relieved. I asked you to come because there is a new study for you."
Hearing the word "research", Kaimo immediately came to the spirit, "Please speak."
"I said before that there are many different gases in the air, and now is the time to use them." Roland recounted his thoughts roughly, "According to the records of Elementary Chemistry, oxygen and nitrogen occupy the air Now I need to separate the two gases for chemical production.”
Kemmer thought for a moment and replied, "You mean, use their different properties...such as different boiling points and melting points to separate?"
"That's right," Roland nodded approvingly, "Condense the air and then heat it 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 much lower than the freezing point, with the current temperature It is difficult to do it by conventional means, so it must be achieved with the help of Agatha's ability."
"Turn air into liquid," Kemmer grinned, stroking his beard. "That sounds very interesting."
"If the temperature is lowered further, they can even become solid, like ice cubes," Roland smiled. This is definitely a scene that contemporary alchemists have never imagined. The premise that the seemingly illusory gas can be held in the hand is to take antifreeze measures.
Agatha wondered, "I also read some of that book, but when I froze the air, I didn't see it solidifying into multiple gases."
"Because they don't form layers when mixed together, it's hard to tell with the naked eye," Roland explained. "The first thing that gets eliminated is carbon dioxide, which has a relatively high freezing point, but is very low in air, so You won't even notice the tiny particles that solidify. Then there's oxygen and nitrogen, which blend perfectly into each other and have a pale blue color that looks like a pure substance if you don't separate it. In fact , liquid nitrogen should be colorless."
"what should we do?"
"Prepare the fractionation vessel first," the prince said with the corners of his mouth raised. "This is a big project."
There is no doubt that Agatha alone is not enough. Glass is easily broken in repeated changes in temperature, so containers for liquid air can only be made of all-steel shells. This is not difficult for Anna, but the fully enclosed shell will make it impossible to observe the change of liquid air when heating up, so it is necessary to use Sylvie's magic eye to observe the scene inside through the container, and then let Aige Sha recorded the specific amount of magic power consumed when the liquid nitrogen was boiling, so as to obtain the temperature parameters for stable production.
This preparation took three days.
When the container was completed, Roland visited the chemical laboratory to guide the town to conduct the first test of oxygen and nitrogen separation.
