I was a village chief in a primitive society

Chapter 547: There is the most important problem to overcome. (3 more please customize)

"Well, this is something to pay attention to."Su Bai said seriously, there are many people on the other side of the earth who died due to carbon monoxide poisoning.

So this is more dangerous, which is why he wants to create heating.

There is not much other than using fire pits for heating. In addition to its usefulness, the second issue is safety.

He doesn't want the entire Yong'an Building to die from poisoning, or else it will be bad if the sparks in the fire pit jump out and catch fire.

And what he thinks of using a boiler to generate heating is not A very difficult thing. On the other side of the earth, it is the same as boiling water at home.

It’s just that the water vapor of the boiled water is emitted casually, and the principle of heating is to transport all the water vapor to inside the room to achieve the heating effect.

The device Su Bai painted is to diffuse the heat energy into the room through those pipes, and then transport the warm air out through the louvered radiator. The heat energy carrier Su Bai chose is water vapor , that’s because its upper temperature limit is higher.

The most important thing is to facilitate recycling. In the primitive era, things that could be recycled were the king, because the conditions here are not as good as those on the earth, and you don’t have to worry about many things.

Anyway, as long as The boiler in the small house is always burning, and the steam pressure generated will make every tiny high-temperature water droplet fill all parts of the pipe, which can continuously provide heating. This is the most important thing. Of course, water vapor Heating is not without its shortcomings. The shortcomings are the welding between pipes, or the durability of the pipes.

If there is a problem with any of these two points, the pressure generated by the high temperature will cause the pipes to explode.

You must know that pipe explosions It’s no joke, as long as those ultra-high temperature water vapor touches the skin, your skin will split instantly, and the pain will be no less than an arrow piercing the flesh wall.

"Wu, according to what you said, you need to heat water and then have water vapor to keep warm. But this weather will make all those people freeze. It would be a waste of firewood to keep burning. Yanhua said doubtfully.

"This problem has been solved. It will be better to use kerosene nuts to burn it. During the whole snow and ice period, not many kerosene nuts will be used."Su Bai said.

By then, the heating system will be able to operate together with the water heater system. Anyway, the materials needed are the same.

"Yes, there is this good thing, Wu, but how do we get the boiling water vapor into the room?" Yanhua asked curiously.

Although the combustion problem was solved, she saw that the boilers on the drawing were all outside Yongan Building.

If the water vapor produced by combustion was then, wouldn't all the water vapor be outside Yongan Building? In such a room How come it's still warm? This is something that the horned lady can't figure out.

"You see these lines. Without these lines, there are pipes. The water vapor generated will enter the room along these pipes."Su Bai explained

"Wu, what materials are these pipes made of? Still using cement?"Yanhua looked at the drawing carefully.

She didn't know what material was best to use. She thought of many materials but none of them was suitable.

"This is a problem that needs to be overcome. We don’t have any ores now. If there are copper mines, these pipes can be made of copper."Su Bai said.

When he was thinking about building a heating system, he also considered the problem of pipelines. This is currently the most difficult problem to overcome. At present, the

Yanlong tribe does not have many copper mines, only a few, but Those were simply not enough to make pipes.

He thought of many kinds of materials but was rejected by himself, because there were many kinds of materials that could not be made.

Those materials were either easy to break or could not completely transport water vapor into the room. , in short, nothing is suitable.

"Copper mine? Wu, is this copper ore the same thing as iron ore?"Yanhua heard another new word

"They are all similar things, there is not much difference in essence, they all belong to the same type of ore."Su Bai explained.

He also thought that if these ores were available now, making weapons and making these pipelines would not be a problem.

"Wu, let us look for these ores, maybe we can find them."Yanhua suddenly became serious.

"Well, that's what I think too. Let's set out to find those ores tomorrow."Su Bai also became serious.

He thought that instead of just dreaming here, he might as well take action and look for it, and maybe he could find something.

"Wu, let me set out tomorrow, and I will definitely find these ores for you."Yanhua's red eyes are full of seriousness.

"Don’t worry about it now. I’ll make some plans tonight and I’ll arrange the personnel tomorrow."Su Bai said in a deep voice.

You can't be careless when there is heavy ice and snow. Everything must be carefully planned.

"Yes, I understand."Yan Hua said as if she didn't understand.

Sha Lan on the side had been thinking seriously. Looking at the drawing, he suddenly wondered:"Witch, if the water in this boiler boils very hard, will something happen? Problem?"

The cat-eared girl has seen boiling water before, because the fire was very strong at that time, and the boiling water kept splashing out.

The water-burning stove almost exploded at that time, and she still remembers the terrifying scene.

So when she saw this drawing, this idea suddenly came to her mind

"I have also taken your concerns into consideration."Su Bai didn't expect that the cat-eared lady would think about this, and continued to explain:"I won't let this happen."

"Wu, then this situation is really possible, right?"Sha Lan was a little shocked. She didn't expect that her worries were true.

"Well, at that time, I had someone create an automatic pressure reduction method. When the pressure in the furnace is too high, a high-speed rotating flywheel will open the valve, so that the pressure can be relieved. Su

Bai took a sip of water and continued to explain:"When there is no pressure in the boiler, there will be no explosion.""

He had thought of this from the beginning, because the problem of pressure must be a pressure reducing device.

"After that, I was still worried about the same incident as the last boiling water incident. Sha Lan said happily.

But the cat-eared girl also knew that she was worried in vain, because she had already thought about this kind of problem, how could the witch not think of it?

"I have to plan the ore search now, so you can go ahead and do your work."Su Bai said

"yes."The girls said in unison.........................................
