The next day, early in the morning.
When Du Qi got up from Li Yanyun's bed, it was snowing heavily outside the window. It was already a vast expanse of white. It was almost nine o 'clock, and Li Yanyun had already left.
Du Qi got up, washed up, and had breakfast. Then he went to the study unhurriedly.
In the study, Du Qi was dealing with today's government affairs. In a short time, he arranged all the government affairs. After all, there were only three counties in Yizhou, Yiwu, Rouyuan, and Natoshi. The land was not that big, so it was not difficult.
All aspects were progressing in an orderly manner.
Everything was not difficult.
Du Qi's main task was to extract some useful books from his memory when he was free and put them on the bookshelf in the study for future use.
Time passed by little by little.
It was almost noon.
At this time, Liu Jian came in and reported that Tang Zhongsheng and Wang Wenkai had come together. Du Qi immediately ordered the two to enter. At this moment, Du Qi's face showed a look of expectation.
When Du Qi met the two yesterday, he gave them the mold for making honeycomb coal. A day later, the two estimated that the mold had been made.
With the mold, they could make honeycomb coal and get rid of the current way of burning coal. Under the premise that the technology was not developed, the burning of honeycomb coal was cheaper.
Not long after, Tang Zhongsheng and Wang Wenkai came in together. In Tang Zhongsheng's hand, there was a mold for making honeycomb coal. After the two of them greeted Du Qi, Tang Zhongsheng immediately handed over the mold and said, "Your Highness, this is the honeycomb coal mold made according to your instructions. It has been made. Your Highness, please check it."
Du Qi stood up and picked up the honeycomb briquette mold from the table. Without any delay, he called for the craftsmen in the fu and had them bring over some coal and yellow mud. Other than that, he also added a little bit of charcoal powder.
They were ready to make it.
The proportion of the mixture was about 80% coal, 19% yellow mud, and the remaining proportion was given to the charcoal powder. Once all the raw materials were prepared, Du Qi asked the craftsmen to mix them according to the ratio and add water to turn the coal powder into mud.
After this step was completed, Du Qi asked the craftsmen to solidify it into a mold.
One by one, honeycomb briquettes were formed and placed on the ground. The weather was cold and it was snowing heavily. It was almost impossible for the dust balls to harden outside.
Du Qi instructed the craftsmen to move all the briquettes into the room. Because of the burning coal, the temperature in the room was high, and it could dry and harden in the shortest amount of time.
After Du Qi had the craftsmen make a simple batch, he dismissed them.
Tang Zhongsheng looked at Du Qi and asked, "Your Highness, what is the value of honeycomb briquettes?"
Du Qi said, "When the honeycomb briquette hardens, you will know. Come, there's one more thing you need to do now. You need to make a honeycomb coal stove. Only then can it be used for cooking. "
Immediately, Du Qi turned back to the study and gave the honeycomb coal stove design to Tang Zhongsheng and Wang Wenkai.
The honeycomb coal stove was actually very simple.
It was roughly cylindrical in shape, wide at the top and narrow at the bottom. At the center of the top, burning briquettes were suspended in the air. Below the briquettes were iron bars to block the briquettes so that they could burn in the center of the stove. It was also good for ventilation to promote the combustion of the briquettes.
When they were no longer in use, they only needed to cover the vent at the bottom with a lid. Without air entering the briquettes, the oxygen content would decrease, and the combustion speed would be greatly reduced. It could also serve as a seal.
Such a honeycomb coal stove could have a hole in the center to hold a briquettes. It could also have two holes or three holes to hold multiple briquettes to form different firepower.
Du Qi's designs were all categorized into different categories.
After Tang Zhongsheng looked at it, he said, "Your Highness, this is very simple and not complicated. After all, such a shape is equivalent to making a mold. We will be able to complete it by tomorrow at the latest. After the stove is dried, we will send it over. "
Du Qi said, "I will wait for your good news. When the time comes, I will demonstrate the use of the honeycomb briquettes. The appearance of this honeycomb coal stove is a good thing. "
Tang Zhongsheng and Wang Wenkai were confused. They did not understand and could only take one step at a time. They would first complete Du Qi's arrangements. The follow-up experiments would be done after the production was completed.
After the two of them left, Du Qi also returned to the study.
Du Qi had a smile on his face.
The appearance of the briquettes was the beginning of the utilization of resources. Although this was the most ordinary utilization of resources, many things, as long as there was a little influence, would gradually expand, and thus extend more and more things.
Du Qi was reading in the residence. In the blink of an eye, it was the next day.
Early in the morning, Tang Zhongsheng and Wang Wenkai came and brought the honeycomb coal stove. This honeycomb coal stove was a three-hole honeycomb briquettes made directly. The interior of the stove contained two layers of honeycomb briquettes, a total of six honeycomb briquettes.
Du Qi looked at the stove that was sent over. He ordered someone to invite Liu Zhengxi, Guo Xiaozheng, Jin Wuque, Yu Deshui, Yuan Yin and Yi Fusheng over. At the same time, he asked Liu Jian to start a fire to ignite the honeycomb briquettes that had hardened last night.
It was easy to ignite the honeycomb briquettes. The three honeycomb briquettes were at the bottom layer.
This ignited the briquettes.
Moreover, when placed on a metal bar, they could continue to burn in the air. This was because there was a hole at a ninety degree angle at the bottom. It was the ventilation hole under the honeycomb coal stove. It was also the location of the ventilation hole. The honeycomb briquettes below burned. Three more honeycomb briquettes were placed on the top layer, a total of six honeycomb briquettes were placed in the stove.
The honeycomb briquettes burned slowly. As the heat gathered, the fire gradually grew stronger.
However, Du Qi could not wait any longer. He asked Liu Jian to place an iron pot on top of the stove. After filling the pot with water, Du Qi asked Liu Jian to take a cattail leaf fan. He placed it at the ventilation hole and continuously fanned the air into the stove.
As the cold wind blew in, the bottom layer of honeycomb briquettes burned rapidly. Under the increasing heat, the bottom layer of honeycomb briquettes quickly turned red, releasing a torrential heat. Even the top layer of honeycomb briquettes started to ignite.
The fire was getting stronger and stronger.
Not long after, Liu Zhengxi, Guo Xiaozheng and the others entered together. The six of them went to the backyard. Although the wind and snow were heavy, it was still fine in the house. They would not be affected by the wind and snow.
The six of them looked at Du Qi. When they saw Tang Zhongsheng and the others, as well as the honeycomb coal stove, they all had strange expressions on their faces.
What was going on?
Liu Zhengxi knew Du Qi's personality. He especially knew that Du Qi was good at making new things. He knew that there were craftsmen, so it must have been Du Qi's guidance to make new things.
Liu Zhengxi said, "Your Highness, did you call us here together because you've made a new item?"
Du Qi said, "There is indeed a new item that can be used to boil water, cook rice, and cook."
As he spoke, Du Qi squatted down and looked into the honeycomb coal stove through the gap under the iron pot. Under the iron pot, the flames were already burning fiercely. Under the burning of the two layers of firepower, it was not weak at all.
Cooking and cooking were all fine.
Everyone was puzzled.
They did not understand what was going on.
Du Qi did not explain too much. He directly ordered, "Liu Jian, bring your various utensils and cook a dish casually. Although it's winter now, it can still be used. "
"Yes!"
Liu Jian immediately agreed.
He also wanted to test the firepower. After all, this honeycomb coal stove was not bad.
Du Qi's eyes were full of anticipation. Liu Jian's demonstration would make everyone realize the benefits and convenience of the honeycomb coal stove. With the honeycomb coal stove, as long as one was willing to spend a little money, it could be used to boil water, cook rice, or cook.
