Boiler heating systems are not complicated things. The essence is to heat boiling water, then transport heat energy to the room through pipes, and then diffuse it by the radiator.
The carrier of thermal energy can be water or water vapor. The reason why Roland uses the latter is that the steam temperature upper limit is higher and it is more convenient to cycle.
As long as the boiler is constantly burned, the steam pressure generated will automatically fill every corner of the pipeline with tiny high-temperature water droplets, and even a water pump is not needed.
Of course, water vapor heating is not without its shortcomings. The pipeline is always in a high-pressure environment. If the interface is not firm, it is easy to cause leakage or even explosion. As long as two or three hundred degrees of high-pressure steam is reached, it will be broken, so the installation quality requirements are higher.
Anna's black wire welding can ensure the strength of the interface, and coupled with Soloya's coating, this disadvantage 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 the centrifugal speed 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 exhaust the gas to reduce pressure.
The last safety line was located at the connection between the boiler and the two main heating pipes, and 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 normally, an explosion will occur in the boiler room without endangering the people in the room.
When the heating system was running, the scene in the castle was completely changed.
The heavy and thick winter clothes disappeared, and the witches changed into autumn clothes again. Looking at the colorful girls talking and laughing in front of them, Roland felt that his motivation for work had increased by five percentage points.
Of course, these facilities are all auxiliary equipment built to enjoy, or to create a better working environment.
What we need to do next is an important project that concerns the future of the Western Region.
That is to realize artificial synthesis of ammonia, reduce dependence on saltpeter, and thus bring the production of chemical explosives to a whole new level, so that it can meet the requirements required for automatic shooting of weapons.
If this goal can be achieved before the end of winter, it will undoubtedly put a heavy bargaining chip on the planned spring offensive.
Roland called Kemostrier and Agsha to the office.
How have you been working together these days?he asked with a smile.
One is the chief alchemist in Border Town. Apart from his extremely passionate love for alchemy, he almost cares about other people's feelings and opinions.
One person comes from the Witch Kingdom four hundred years ago. He has the pride of being a member of the Discovery Society of the highest research institution. Both of them are straightforward. Putting them together is like a gunpowder barrel that is about to explode.
Roland was also often worried about whether they would have a dispute, but both of them had to work together for both nitrifying gunpowder and synthetic ammonia, so he still had to ask about the situation first. If there was no harmony, he could only mediate.
Very good. The first sentence of Kaimo surprised Roland. Miss Aegas's ability is very helpful to chemical testing. Now I have found the stable synthesis temperature of nitrified*glycerol. There is no problem with the laboratory making. We are further testing the possibility of industrial production... It can be said that without the ice cup, none of this can be achieved.Oh, because I was too busy with work, I didn’t inform you.He paused, and by the way, if you want to inquire about this, can you let me go back to the lab now? I still have a lot to do.
Uh...is that true?Roland looked at Agesha, who nodded.
Mr. Kaimo's knowledge is indeed different from that of ordinary people, especially his understanding of elements, which is quite similar to the exploration of secrets.Our cooperation is very pleasant at present. If it is put in Tachila, he will inevitably be absorbed by the Federation.
Is it easier to get along with straight-minded people?
It seems that I was worried about it, and why did the chief alchemist have a better attitude towards the witch than to me?
It was so sad... Roland cleared his throat after whining in his heart. Since that's the case, I'm relieved.I'm asking you to come, there is a new study to give to you.
Hearing the word research, Kaimo immediately felt spirited, please say.
I have said before that there are many different gases in the air, and now it is time to use them.Roland briefly explained his thoughts. According to the records of "Elementary Chemistry", oxygen and nitrogen account for 99% of the components in the air. Now I need to separate these two gases for chemical production.
Kemo thought for a moment and replied, "You mean, use their different characteristics...such as different boiling and melting points to separate?"
That's right, Roland nodded in praise, condensed the air and then heated up the temperature. The boiling point of nitrogen should be lower than oxygen, so it will be distilled out of the liquid first. Since this temperature is far lower than the freezing point, it is difficult to achieve with current conventional means, so it must be achieved with the help of Agsha's ability.
Turning the air into liquid, Kaimo grinned while touching his beard, which sounded very interesting.
If the temperature is lowered further, they can even turn into solids, like ice, Roland smiled.
This is definitely a scene that contemporary alchemists have never imagined. The seemingly illusory gas can be held in the hands of the prerequisite is to take anti-freeze measures.
Aegas wondered, I read some of the book, but when I freeze the air, I didn't see it solidifying into multiple gases.
Because they don't have layering when they are mixed together, it's hard to tell with the naked eye, Roland explained that the first thing that was excluded is carbon dioxide, which has relatively the highest freezing point, but has extremely low content in the air, so you won't even notice the fine particles it solidifies.Next is oxygen and nitrogen, which can blend perfectly and appear light blue. If not separated, it looks like a pure substance.In fact, liquid nitrogen should be colorless.
What should we do?
First prepare the fractionation container, the prince raised his mouth and said, "This is a big project."
There is no doubt that Agesha alone is not enough.
Glass is prone to shattering during repeated temperature changes, so the container that holds 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 change in liquid emptying when the temperature rises. Therefore, it is also necessary to use Sylvie's magic eye to observe the scene inside through the container, and then let Agesha record the specific amount of magic consumed when the liquid nitrogen boils to obtain the temperature parameters of stable production.
This preparation lasted for three days.
When the container was manufactured, Roland visited the chemistry laboratory and guided the town to conduct the first test of oxygen and nitrogen separation.
