HCB Chapter 76 With the General, Shangqing Plays in Mud
Chapter 76 With the General, Shangqing Plays in Mud
It was snowing heavily outside, and inside the dilapidated house, enthusiasm was on fire.
The attendant Qin Feng ran back and forth several times, and usually came over a dozen jars of drunken fairy wine.
Veterans also came in and out, returning with pots of steaming stew.
Looking at the sporadic diced meat in the dish, Ying Yu knew that these veterans had spent a lot of money to entertain him.
The snow fell harder and harder, and the temperature in the house dropped significantly.
At this time, an old soldier came in with a brazier.
Looking at the smoky brazier, Ying Yu was slightly stunned.
He sniffed hard, and a familiar smell hit his face.
What is burning in this brazier is not charcoal, it seems... It seems to be coal.
Ying Yu was born in the Northeast, so he is no longer familiar with coal.
I remember when I was a child, he would gather around the stove in winter, not to keep warm, but to bake potato chips.
Thinking of this, Ying Yu couldn't calm down any longer, and quickly walked to the brazier, picked up a piece of black coal and asked:
"Where did this thing come from?"
Seeing this, the veteran thought that Ying Yu had choked on the smoke, and said in embarrassment:
"I can't afford to burn charcoal. The Shi Nie I picked up from the mountain... the smoke is a little bit thicker. My lord, please forgive me."
Ying Yu nodded. He remembered that coal first appeared during the Spring and Autumn Period and the Warring States Period.
The coal at this time was called Shi Nie, and its main function was to make ink.
As for its combustion characteristics, it has not been widely used.
"Which mountain did you pick this thing up from?"
After confirming that it was coal, Ying Yu's face suddenly showed excitement.
Being able to be picked up at will means that there is a coal mine with extremely high output nearby, and only Ying Yu knows what this means.
"Return...Master Hui, this thing is not easy to burn, no one wants it, and it can be seen everywhere in the mountains behind."
Seeing Ying Yu's expression was wrong, the veteran replied nervously.
Everywhere you can see, what a huge coal mine it must be.
The biggest difference between coal and charcoal is that coal has a higher density and more impurities!
Therefore, compared with charcoal, pure natural coal does not burn sufficiently, is easy to extinguish, and has relatively large smoke!
But if this coal is made into a honeycomb shape, it can solve the problem of burning!
The shape of the briquette is naturally needless to describe. The densely packed holes on it are equivalent to artificially opening a lot of ventilation holes for the coal, which increases the contact area with the air, so that the coal can be fully burned!
The coking process Daqin does not have the infrastructure and conditions!
But briquette is easy to make, and it is not simple, it is nothing more than using the principle of increasing the contact surface with the air to achieve a combustion-supporting effect!
Although honeycomb is useless except for heating and burning fire, it cannot be used for smelting!
But this is enough, the coal mines in this era have not been mined, they are all rich ore!
The price of charcoal and firewood is much higher than the price of coal that can be seen everywhere at this time!
People who freeze to death in Daqin every winter don’t know who they are. If the coal mines can be mined and made into briquettes and sold at a low price, it will be a great thing to benefit the world!
Even if the issue of heating is not considered, the wide application of briquettes can also reduce the living pressure of the people!
It is too simple to make briquettes. I can still vividly remember the childhood Ying Yu who beat briquettes when he was a child.
"My lord, what's wrong with this thing?"
Seeing Ying Yu holding Shi Nie in a daze, Meng Yi came over.
He also knows this Shi Nie, the young master is staring at this thing, is there anything strange about this Shi Nie?
"Get some dry soil and water!" Ying Yu suddenly ordered!
Qin Feng at the side immediately ran out when he saw this,
In the blink of an eye, dry soil, clear water, and Shi Nirvana are ready!
"Come! Break Shi Nie!" Following Ying Yu's order, Qin Feng immediately raised his hands.
He smashed Shi Nie with a stone, and then Ying Yu ordered the veterans to sift the loess finely with a dustpan!
The reason why loess is used is to shape the briquettes.
The quality of coal mines these days is nothing to say, there are not many impurities, and the main reason for incomplete combustion is that its density is too high and the contact surface with air is too small!
Honeycomb coal can effectively solve this problem!
In a short while, under the busyness of everyone, the stone nirvana powder was poured, and the loess was all finished!
"What do you do next, son?"
Qin Feng looked at Ying Yu anxiously, waiting for orders.
After a little thought, Ying Yu said, "Mix the stone powder and loess together!"
Qin Feng immediately started to act when he heard the words.
"Add water, why don't you stir it up if you don't add water."
As soon as these words came out, Qin Feng was stunned, and looked at Ying Yu dumbfounded:
"My lord, wouldn't it turn into mud if you add water?"
The rest of the people also nodded one after another, completely unaware of what Ying Yu was doing with this operation.
Seeing this, Ying Yu didn't bother to talk nonsense with them, so he did it himself.
He remembers the ratio of clear water, loess, and stone nirvana when making briquettes!
In the blink of an eye, a black lump of mud appeared in Ying Yu's hands.
Seeing that Ying Yu had done it himself, everyone quickly stepped forward to imitate it.
Meng Yi's whole face turned green.
Can anyone explain to Ben Shangqing what is going on?
A Daqin son with a great general, himself, Daqin Shangqing, and a group of veterans playing in the mud, if it gets out, this face is probably not acceptable.
After a while, more than a dozen briquettes of different shapes appeared in front of Ying Yu.
Ying Yu looked at the briquettes in front of him, and suddenly smiled, each of them has its own merits, competing for excellence.
But that doesn't matter.
What shape does it matter?Just enough holes!
Ying Yu looked at the strangely shaped briquettes in front of him and expressed his satisfaction.
In this way, the first batch of briquettes in Daqin was successfully born.
After that, it only needs to be manipulated, and this cheap and convenient briquette will quickly replace charcoal among the people.
After all, charcoal is still too expensive!
Compared with the expensive charcoal, the smell of briquette is not so good, and it is still easy for ordinary people to accept.
Honeycomb was finally finalized.
Although the shape is a bit weird, as long as there are enough holes, it will not affect its usability.
It's just that the briquettes that have just been produced are still relatively moist, so there is no way to burn them, otherwise the room will be full of smoke!
Ying Yu baked the briquettes around the brazier and waited quietly!
"My lord, what are you doing here?"
Wang Li finally couldn't hold back his curiosity and asked.
"Nature is a good thing."
Ying Yu said calmly, and then called the veterans to continue drinking.
