"Coal?" Hearing this new term, several elders, including Khan Erduo, showed puzzled expressions on their faces. Fortunately, with Tang Jin's previous series of operations, they clearly knew that the names of the same thing were sometimes completely different between the two sides, so they waited patiently for Tang Jin to explain.

Tang Jin didn't have any ink, and after talking a little about the characteristics of coal, everyone's faces showed a look of sudden realization, and Khan Erduo took the lead and said: "If we understand correctly, this thing you said is called flint by us." Are you going to use this for warmth? Although it does burn, and we used it to keep warm before, but then ......"

"Someone often disappears for some reason, right?" Tang Jin directly interrupted the other party. Hearing this, Khan Erduo was stunned for a moment, and then nodded approvingly, and did not delve into why Tang Jin knew this, anyway, now Tang Jin is basically equated with omniscient in her eyes.

"It's just that someone will die, because the burning coal will release a large amount of carbon monoxide, and this thing ...... after inhaling into the human body" As he was saying, Tang Jin suddenly realized something, looking at everyone's confused looks, obviously didn't understand what Tang Jin was talking about, smiled bitterly, spread his hands and said: "You can understand that this thing has produced a kind of poison, because the stove you used is wrong and the room is not ventilated, so it caused people to die inexplicably." ”

After explaining this, everyone suddenly showed a sudden realization, and then the second elder seemed to think of something, and looked at Tang Jin suspiciously: "His Royal Highness the Prince just said that there is a problem with the furnace we use, but His Highness knows how to make the correct stove. ”

"Of course, I'll go and draw the drawings later, get your blacksmiths ready to work, and collect as many coals as I can, and then smash them all for me, remember, literally. If you want to use coal for heating correctly, you have to change not only the furnace, but also the coal. Saying this, Tang Jin threw everyone away and went straight back to his residence.

The heating problem of the Khan Meng tribe is an absolute old problem, and if you want to completely change it, you have to change it from the root, that is, their housing, replace the house with a reinforced concrete structure, and then carry out central heating, which is in line with the standard of "solution" in Tang Jin's heart.

But there is obviously no time for him to toss these things at the moment, and it is now the end of February, which is the coldest day of the Khan Meng tribe. Obviously, it is impossible for him to complete such a huge project in a few days, so he can only settle for the next best thing, build a briquette stove first, and then improve it little by little after this winter.

"In the end, it's still useless." Tang Jin couldn't help but sigh, and then silently drew the drawings.

Briquette furnaces and briquette machines don't have much technical content

It only took a while for Tang Jin to draw it, and the blacksmith of Khan Meng was not considered to be covered, just glanced at the drawings, asked some specific parameters, and then started work directly, twenty or thirty blacksmiths started at the same time, relying on manpower to form the momentum of the assembly line, and it took less than an hour to prepare the first finished product, and the coal that Tang Jin needed was also sent over. Although coal will kill people, there are still survivors in the tribe, no matter how this is also a fuel, when it is really cold and there is no way, on the one hand, it is possible to be smoked to death, and fools know how to choose.

Looking at the pulverized coal in front of him, Tang Jin immediately commanded the two strong men to start tinkering with honeycomb coal, although he didn't mind doing dirty work, but when someone could do it for him, why not do it?

Under Tang Jin's command, a pile of pulverized coal soon turned into pieces of honeycomb coal. instructed a few people to move it out to dry, with the weather here, it could be dried in a day, and Tang Jin returned to his room irresponsibly after leaving drawings of chimneys, kettles and even aluminum alloy pots for a few blacksmiths.

The next day, in Tang Jin's room.

Compared with the humble days ago, there are a lot of things in Tang Jin's house today, the most eye-catching thing is the briquette stove that was just made yesterday, and the chimneys stacked aside, with little difference in length and thickness.

That's right, the first briquette stove Tang Jin chose to install in his room. On the one hand, this thing is made by himself, whether there is danger or not, he knows it himself, but others don't know, and it is most reassuring to let him go; Secondly...... He's cold, too! Although there is also a bonfire for heating in the house, not to mention whether that thing can be burned overnight, even if Tang Jin can, he doesn't dare to let him burn it overnight, otherwise it is unknown whether he can wake up the next day.

He set the stove and placed it directly in front of his bed to keep him warm, then he installed the chimney and protruded it through the hole in the roof, and finally took a few briquettes, filled it into the furnace, and threw a large ball of lit straw into it with the expectant eyes of the crowd.

As the straw slowly burned, the honeycomb coal also followed, and after a while, the entire tent became hot, and Tang Xu, who was wearing thicker, even had some bright beads of sweat on his forehead.

Seeing this, Tang Jin took out the kettle sent by the celebrity early in the morning, went to the door to fetch a pot of water, sat on the stove, and then directly took off his coat, wearing only a cotton suit, took the tea set on the side, and sat in front of the stove without care, fiddling with the tea set while roasting the fire, and waiting for the water to boil to make a cup of tea.

Seeing this, Han Erduo and the others opened their mouths a little worriedly, but finally swallowed the words that came to their mouths, seeing that Tang Jin's fearless posture was obviously not worried about the so-called toxins.

"Don't stand

Let's find a place to sit. Rest assured, some of the toxins produced by coal combustion are burned directly due to the shape of the briquettes, and the other part is also carried out with the chimney and directly neutralized by the air. As long as the chimney is not blocked and does not leak, you will have no problem burning for a year. Of course, Tang Jin knew what they were worried about, and although he was helpless, he couldn't help but explain.

Everyone was a little relieved when they heard this, although they didn't understand the principle very well, but what Tang Jin said didn't go wrong, he said that if it's okay, it should be fine.

Similarly, after knowing that the biggest drawback of coal had been solved, the minds of Khan Erduo and others immediately came alive. Although their tribe does not have many reserves of coal, there is an open-pit coal mine not far away, which they used to mine back then, and if they start to make briquette stoves now, although it is impossible to spread to the entire tribe before March, they can at least give it to some people who are not in good condition and cannot afford to heat their homes to help them survive this winter.

Thinking of this, several people couldn't do it and immediately said goodbye to Tang Jin, and then ordered one after another to be issued quickly. As a result, the masses of the Khan Mon tribe once erupted in full enthusiasm after the greenhouse, and everyone once again devoted themselves to the manufacture of briquette stoves and honeycomb coal.

Tang Jin didn't care about this. Although the briquette stove is only a transitional product, it is still very useful for the Khan tribe at this stage, and even if he wants to build a reinforced concrete house, it will take at least a year to do so. The heating in the middle still has to rely on the briquette stove, otherwise it will inevitably freeze to death, which is not what Tang Jin wants to see.

In addition, Tang Jin also made up his mind that he would not come up with new technology for at least three months, and even if he did, he would definitely have to find something related to glass, aluminum alloy, briquettes, etc., otherwise it would be cumbersome to add basic technology.

So, the next period of time can be said to be the most leisurely period of Tang Jin in the whole Khanmeng, every day like a janitor around a stove, boiling water on the stove, from time to time to pick up to add some water to his cup, suck two sips, spit out some tea foam, and then sit on the recliner and read the book leisurely. Similarly, because he was warm enough here, Tang Xu and the others basically spent the rest of their time here except for sleeping at night, and they couldn't leave.

In stark contrast, it was the entire Khan Meng tribe, because the two technologies that Tang Jin came up with were the most needed for them at the moment, especially the briquette stove, which was a life-saving thing, and the entire tribe completely entered the crazy mode, but everyone was tired and happy.

In the twelfth year of Tianyu, in mid-February, the Khan Meng tribe began its first step towards modernization, although ...... It's a bit crooked.
