Chapter 225 Entering Xianyang again, what is a heated kang?
When the craftsmen learned the hot kang technology and successfully tested it, hundreds of people quickly integrated into Sanchuan County, with Luoyang as the center and began to radiate in all directions.
Moreover, building fire pits in people's homes does not require wages, and only requires taking care of the food. For a time, everyone looked forward to it.
Since it was an order from the county magistrate's office, the local elder's home was the first one. After a successful test, the villagers cheered and they clearly felt the warmth.
Therefore, villagers from all over the country felt the benefits, and naturally there were no obstacles. Instead, they helped each other, and the speed of building fire pits continued to accelerate.
Seven days later, the craftsmen built an iron furnace and then a chimney. These people were all highly sophisticated talents loaned out by Ying Gao from Shang Gongfang.
When Ying Gao saw the freshly baked stove, he was also amazed. Da Qin Shang Gong Workshop gathered all the skilled craftsmen in the world, and it really lived up to its reputation.
"Sir, it's ready!"
Glancing at Gongshu Qin, Ying Gao smiled widely: "Get a few people to carry it over, and let's try to see how it works!"
"promise."
Under Ying Gao's guidance, he connected the stove to the chimney and started lighting the fire.
After a while, the wood began to burn, and Ying Gao threw the coal that had just come out into it. He didn't know the difference between anthracite and bituminous coal, but this stove would tell him.
A quarter of an hour later, the coals burned and the shogunate became warm.
"Sir, this strategy is feasible!"
Gongshu Qin was overjoyed, his cheeks flushed with excitement: "In this way, the entire Qin Dynasty will lose many lives due to the cold."
"Um!"
Ying Gao nodded, glanced at Gong Shu Qin, and said: "But burning it like this is not an option. Not only is it very smokey, but it is also very expensive and cannot be used by ordinary people."
"Crush the coal into powder, then add wood chips, lime, loess, etc., mix it with water, and knead it into briquettes. You can test how to achieve the appropriate proportions!"
Speaking of this, Ying Gao looked at the thick smoke in the chimney, thought for a moment, and said: "By carbonizing this smoky coal, you can get a kind of coke, which is heat-resistant and has strong firepower, and can be used to forge bronze and iron.
."
"You are responsible for this matter. No one will leak the specific details, otherwise military law will be engaged-!"
"promise."
...........
The reason why Ying Gao did this was to be able to forge iron weapons on a large scale and then replace them with bronze weapons.
Great Qin is not only the Central Plains, but also has countless sea territories. In his lifetime, he doesn't know whether he will be able to destroy large ships and roam the oceans, but the seeds must be planted.
Everything went on the right track, and before I knew it, fifteen days had passed.
Wang Hu was training his troops, and Meng Liao was even more so.
In Sanchuan County, Ma Xing was in charge. At this time, Ying Gao was free. Lying in the shogunate, it was so warm that for a while, he was too lazy to move.
Briquettes are being produced continuously, and the whole Zhengzhou is busy. At this time, briquettes have also entered thousands of households, whether they are used for burning fire pits or not, and the sales volume continues to rise.
At this time, Ying Gao also realized that someone needed to run this business in order to maximize the benefits.
.........
In desperation, Ying Gao returned to Xianyang.
Although coal is not used, it is part of the mining industry, and the large-scale use of coal will inevitably bring about iron tools. At this time, he needs to ask Ying Zheng for instructions, and at the same time, he also needs to promote the heated kang technology to thousands of households.
By then, there will inevitably be a massive influx of money.
.........
"Tie Ying, you wait here, I can go on my own!"
When the weather turns cold, waiting on the horse racing field is already a difficult task. Tie Ying is just his guard, not his retainer. Sometimes, he needs to control the situation carefully.
"promise."
Approaching the Royal City, Tie Ying no longer worried about Ying Gao's safety. After all, the Xianyang Royal City was the most heavily guarded place in the world.
"My son, I pay my respects to my father. My father will be king for ten thousand years, and the Qin Dynasty will be for ten thousand years——!"
Entering the study, Ying Gao bowed solemnly and said.
"Um!"
Ying Zheng was not surprised by Ying Gao's appearance. He got the news the moment Ying Gao set foot in Xianyang City. However, he did not announce it.
Putting down the bamboo slips in his hands, Ying Zheng looked at Ying Gao, and after a while, he said: "You are not in the Jingxian camp, and you have not received the royal edict. Why did you suddenly return to Xianyang?"
Hearing this, Ying Gao's heart skipped a beat. He suppressed his thoughts and said to Ying Zheng, "Father, I have found a coal mine in Sanchuan County."
"And already mined, it can replace charcoal as a fuel!"
"After Gongshu Qin's research, he found that the coal can be used for heating, burning fires, and forging iron tools. Therefore, I came here to report to my father."
Hearing this, Ying Zheng's eyes burst out with extreme light, staring straight at Ying Gao, and said: "Is this true?"
At this moment, Ying Zheng was also shocked.
He naturally knows what kind of changes it will bring to Great Qin if what Ying Gao said is true. As a king, he naturally knows the current situation of Great Qin.
In the Qin Dynasty, bronze craftsmanship has reached an extreme level, and the weapons produced have even surpassed iron weapons. This is the reason why the three armies of the Qin Dynasty have never changed their equipment.
Various thoughts flashed through Ying Zheng's mind, and suddenly, his heart was full of expectations.
Facing Ying Zheng's expectant gaze, Ying Gao said word by word: "This is natural. I will never deceive my father. In Sanchuan County, I and Gongshu Qin have already conducted experiments."
"At the same time, the fire kang technology was developed in Sanchuan County and the stove was built. After testing, the results were good, but there is still room for improvement. This time when I came to Xianyang, I did not bring it."
"What is a fire bed?"
Regarding the stove, although he has never seen it, Ying Zheng can probably guess a thing or two, but he is really confused about the fire kang technology.
Ying Gao slightly cupped his hands towards Ying Zheng and said word by word: "The fire kang has a kang wall built with bluestone blocks. There is a flue in the kang wall, and it is covered with relatively flat stone slabs. The stone slabs
Cover it with mud and smooth it. After the mud dries, you can put a kang mat on it and use it."
"At the same time, the kang has a stove mouth and a smoke outlet. The stove mouth is used to burn firewood. When the smoke and heat generated by burning firewood pass through the wall of the kang room, it heats the stone slabs above to generate heat, causing the kang to generate heat. The smoke finally passes through the smoke outlet of the fire kang.
Expelled to the outside through the chimney.”
"Since the stove mouth and smoke outlet are outside, it will be safe even if you use thin coals to burn it!"
"This not only solves the problem of sitting and sleeping, but also dissipates heat through so many kang surfaces and maintains a higher indoor temperature."
