The fourth volume of the sharp blade out of the sheath Shenzhou moves

The two pots of charcoal were baked warmly, the little yellow mutton was delicious, the wine was good, and Huang Sen's eyelids were fighting, and he was about to lie on the table and take a nap.

"Master, master......"

Suddenly, the shouts of the officials came from the front, Huang Sen slammed his head, slammed his head on the table, the wine suddenly sobered up half, touched his head and shouted angrily:

"What are you shouting about the poverty of the New Year, howling and mourning......"

"It's messed up, it's messed up...... Xitong Pawnshop and Drunken Red Mansion were smashed, Boss Zhou was taken captive, and his life and death are unknown......

The green buildings, restaurants, and teahouses in the city should levy business licenses, saying that it was an order issued by the yamen of the Fuzhou prefect, and that a public security department should be established, which was presided over by Chen Bantou......"

"Who's ......?"

As soon as the words came out, Huang Sen suddenly came to his senses, waved his hand and let the official out, stunned.

After a while, the warm sedan chair in the house came out of the side door and hurried towards the residence of the political envoy.

Similarly, when Li Xiang got the information, he wanted to report it as soon as possible, but was told by the Governor's Mansion that Governor Qin and the three wives were in the Smelting Bureau.

If it were someone else, it would be very strange, how could the dignified governors of the two provinces take their wives to such a dirty place on the occasion of the Spring Festival, when they have nothing to do with their full meals?

Only Li wanted to know that the Smelting Bureau was Qin Du's treasure.

Not to mention anything else, I don't know how many times I personally accompanied him, and with some incomprehensible drawings drawn by Qin Du, he stayed for several hours.

Don't say it, the Smelting Bureau must have results today, and Governor Qin will take his wife to inspect it.

You must know that Governor Qin has an order, no matter when and where, as long as the craftsmen of the Smelting Bureau make things on the drawings, they must tell him as soon as possible.

When Li Xiang went over, the smelting bureau was very lively, and several adults in the attendant room were also accompanied.

What surprised him was that in some simple sheds outside the construction site, there were some briquettes made of strange shapes, cylindrical shapes, with evenly distributed holes in the middle.

And on the side where there is only a wall on three sides, such things are stacked high, at least tens of thousands.

Outside the open space, a coal stove was placed there, and everyone gathered around Chen Meichun to see how to use it.

Put the soft hay at the bottom of the stove, take out the fire fold and blow it vigorously, first ignite the hay, and then put the coarser dry wood, which is no different from the previous stove fire.

When there is a bottom fire in the stove, Chen Meichun picks up a briquette with fire tongs and puts it into the stove, the special coal stove is also cylindrical, with a slightly larger aperture than the briquette, just enough to allow a briquette to be put in.

Everyone watched very seriously and curiously.

Qin Governor summoned everyone over for the New Year, saying that there were good things for them to see, and even said that they wanted to change nature, change the environment, and ...... In short, it's very mysterious.

Where did I think that when I came over, it turned out to be the use of loose coal, which made everyone's hearts rise, Qin Du was playing with them.

However, he is the boss, he has the final say in everything, and everyone is helpless.

Under Chen Meichun's operation, it didn't take long for a moment to see flames coming out of the holes in the briquettes, and the briquettes began to emit blue flames.

The depth of the coal stove is just enough for two briquettes, and when the first one burns, Chen Meichun puts the other one in and aligns the holes of the two briquettes with fire tongs.

The crowd saw flames emerge from one of the briquette holes below, licking towards the second briquette hole.

The top of the coal stove is designed as a ring of protrusions, just enough to sit on a kettle or pot.

Chen Meichun filled a copper kettle with water, put it on the stove, and after about a stick of incense, he heard a booming sound and white smoke coming out of the spout.

"The water is boiling! It's so fast! Qi Wanru clapped her palms happily and cheered.

"Madam, this thing designed by Qin Du is called a honeycomb stove, and the briquettes are called honeycomb coal, a briquette can be burned for nearly an hour, and there is no problem in cooking a meal.

When not in use, seal the top with an iron sheet, and then block the air inlet below with a wooden plug, so that it will not burn again. ”

Chen Meichun took the copper kettle off it and demonstrated it to everyone.

Looking at the fire burning in the hearth, Hong Dixin next to him asked suspiciously, "Chen Zhongyu is exaggerating, right?" How could this burn for that long? ”

"Your Excellency, may I see?" Chen Meichun squatted down, stretched out her hand and inserted a small piece of iron on the honeycomb stove, and the fire in the furnace dimmed.

"My lords, this is the damper, as long as you close this damper, the fire will be reduced.

Put a fresh honeycomb medium in at night, close the damper, and get up early the next morning, the fire can still burn. At this time, you only need to open the damper, and then replace it with a new coal, and in a very short time, the fire will burn very strongly. ”

"That's it!" Everyone suddenly realized, and then thought that this was designed by Qin Du himself, and looked at Qin Haoming with a somewhat different vision.

"That's pretty good." Squatting there, Hong Dixin fiddled with the damper up and down, looking at the fire from time to time, as if he was thinking about something.

"It's all worthless loose cinders, lump coal has been transported away, and not many people pay attention to these ordinary loose coals.

Basically, the people still cut down firewood and trees for heating, and those who have money burn charcoal. Because of the coal thing, it still smells good when burned, and these loose coals are really difficult to clean up.

In addition, it smells when burned, and it can poison people in a closed house in winter.

Now that Qin Du designed it this way, an extra layer was added to the outside of the furnace, and water was filled inside, so that it could be used for two purposes.

First, these water vapors come out, which can neutralize the smell of burning coal. Second, if you have such a stove at home, you can have hot water at any time in winter.

If the fire is turned on completely, the water inside will boil quickly. ”

"There's a lot of good use." Yan Yingyuan admired, "Will it still poison people?"

"Yuan Heng, in fact, when this furnace is completely burning, there will be no such thing as poisoning people. But when it comes to closing the damper, it's still a bit dangerous.

So after closing the damper, try not to put it in the house.

If it must be placed in the house, it is best to put it in a ventilated place, although there is water vapor and some poisonous gas, but there is still carbon monoxide overflow. ”

When it comes to this question, Chen Meichun can't answer it, but Qin Haoming rubs his hands on the side to popularize common sense for everyone.

"But despite this disadvantage, it is negligible compared to his benefits." Xu Jie interjected on the side, then touched his head and wondered: "It's just, Qin Du, what is this carbon oxide?" ”

Ah, I really want to explain it to them, and I can't tell you next year.

"A poison gas from coal." Qin Haoming said lightly, and then turned his head to everyone and said, "Everyone must be very curious, this governor said that it is a treasure."

And during this Spring Festival, call the big guys out of their homes, do you think it's a bit exaggerated? ”

Qin Haoming said it interestingly, and when he said the word big guy from his mouth, many people present laughed embarrassedly.

"Qin Du, are these things made of cinders?"

After laughing, Hong Dixin asked.

"Of course, each briquette is also mixed with 20 percent clay." Qin Haoming nodded affirmatively, and began to break the news.
