I’m Marquis in Great Tang

The next day, early morning.

When Du Qi got up from Li Yanyun’s bed, the snow was flying outside the window, and it was already white. By this time, he had already arrived, and Li Yanyun had already left.

Du Qi got up to wash and eat breakfast before going to the study at a moderate pace.

In the study, Du Qi handles today’s government affairs. Within a short period of time, various government affairs were arranged. After all, it is now the Land of a Province in Yizhou, with only three counties, Yiwu, Rouyuan, and Nazhan. The area is a bit bigger, so it doesn’t take much effort.

All aspects are progressing in an orderly manner.

Everything is not difficult.

Du Qi’s main task is to extract some useful books from the memory in his mind when he is free, and put them on the bookshelf in the study for later use.

Time is passing by.

It’s almost noon.

At this time, Liu Jian entered and reported that Tang Zhongsheng and Wang Wenkai had come together. Du Qi immediately ordered the two of them to enter. At this moment, Du Qi’s face showed an expression of expectation.

When Du Qi met the two yesterday, he gave them the mold of the manufacturer Hexagonal Household Coal Briquette. One day passed, and the two estimated that they had already made a mold.

With molds, Hexagonal Household Coal Briquette can be manufactured, and you can get rid of the current coal burning method. Under the premise of underdeveloped technology, the combustion of Hexagonal Household Coal Briquette is cheaper.

Not long after, Tang Zhongsheng and Wang Wenkai entered together. In Tang Zhongsheng’s hands, he also carried a Hexagonal Household Coal Briquette manufacturer mold. After the two paid respect to Du Qi, Tang Zhongsheng immediately handed over the mold and said, “His Royal Highness, this is according to your instructions. The Hexagonal Household Coal Briquette mold manufactured by the manufacturer has been completed. Please check it out.”

Du Qi stood up and carried the Hexagonal Household Coal Briquette manufacture mold on the desk. Without delay, he called the craftsman at the house and asked the craftsman to send coal stone and some yellow mud. In addition, he added A little bit of charcoal powder.

This is preparation for manufacturing.

The mixing ratio is about 80% of coal rock, about 19% of yellow mud, and the remaining proportion is given to charcoal powder. All the raw materials were prepared properly, Du Qi asked the craftsmen to mix according to the proportion, and then added water to make the coal powder become muddy.

This step is completed, Du Qi let the craftsman use the mold to solidify and shape.

One Hexagonal Household Coal Briquette ball is formed and placed on the ground. Now that the weather is cold and heavy snow is flying, it is almost impossible to leave the briquettes hard.

Du Qi directly ordered the craftsman to transfer all the briquettes that have been formed into the room. Because there is coal burning, the temperature in the room is high, and it can dry hard in the shortest time.

Du Qi let the craftsman simply manufacture after a batch, let the craftsman go down.

Tang Zhongsheng looked towards Du Qi and asked: “His Royal Highness, where is the value of Hexagonal Household Coal Briquette?”

Du Qi said: “Wait for Hexagonal Household Coal Briquette to harden Later, you will know. Come, you have one more thing now, you have to manufacture a Hexagonal Household Coal Briquette stove, which is conducive to burning and cooking.”

Immediately, Du Qi turned around. Back to the study, he gave Tang Zhongsheng and Wang Wenkai the design drawings of the Hexagonal Household Coal Briquette stove.

The Hexagonal Household Coal Briquette stove is actually very simple.

It is roughly cylindrical, wide at the top and narrow at the bottom, with the burning briquettes suspended in the center liner above. Below the briquettes is an iron bar block so that Hexagonal Household Coal Briquette can burn in the center of the Hexagonal Household Coal Briquette stove, and it is also conducive to ventilation to promote the combustion of Hexagonal Household Coal Briquette.

When it is no longer in use, the bottom vent only needs to be covered with a lid. The Hexagonal Household Coal Briquette lacks air to enter, and the oxygen content is reduced, and the combustion speed is greatly slowed down. Play a closed role.

Such a Hexagonal Household Coal Briquette cooktop can have a hole in the center to accommodate a Hexagonal Household Coal Briquette. It can also be two-hole or three-hole, to accommodate multiple Hexagonal Household Coal Briquette to form different firepower combustion.

Du Qi’s design drawings have different classifications.

After reading this, Tang Zhongsheng said, “His Royal Highness, this is very simple and not complicated. After all, such a shape is equivalent to making a mold. We can finish it tomorrow at the latest. The stove is dried. Later, we will send it.”

Du Qi said: “This king is waiting for your good news. When the time comes, he will demonstrate the use of Hexagonal Household Coal Briquette. This Hexagonal Household Coal Briquette cooker It’s a good thing to appear.”

Tang Zhongsheng and Wang Wenkai heard it in the mist, and they didn’t understand them well, so they could only take one step at a time. They first complete the arrangement of Du Qi and follow-up tests, and wait until the manufacturing is completed.

After the two left, Du Qi also returned to the study.

Du Qi has a smile on his face.

The emergence of coal is equal to the beginning of resource utilization. Although this is the most common use of resources, many things, as long as they have a little impact, will gradually extend, thereby extending more and more things.

Du Qi was reading at the mansion, and it was 2nd day in a blink of an eye.

Early in the morning, Tang Zhongsheng and Wang Wenkai came and brought the Hexagonal Household Coal Briquette stove. This Hexagonal Household Coal Briquette stove is a three-hole Hexagonal Household Coal Briquette directly manufactured, and the inner bladder of the stove accommodates two layers of Hexagonal Household Coal Briquette, a total of six Hexagonal Household Coal Briquettes.

Du Qi looked at the stove sent, while instructing people to invite Liu Zhengxi, Guo Xiaozheng, Jin Wuque, Yu Deshui, Yuan Yin and Yi Fusheng to come, while letting Liu Jian catch fire and ignite yesterday Hexagonal Household Coal Briquette, which has dried hard at night.

The ignition of the Hexagonal Household Coal Briquette is also easy. Three Hexagonal Household Coal Briquettes are on the bottom.

This is ignited.

And rest on the iron bar, can contact the air to continue burning. Because the bottom is a 90-degree corner hole, which is the vent below the Hexagonal Household Coal Briquette stove, and it is also the location of the closed vent. The Hexagonal Household Coal Briquette is burning at the bottom, and three Hexagonal Household Coal Briquettes are placed on the upper layer. A total of six Hexagonal Household Coal Briquettes are in the Hexagonal Household Coal Briquette cooker.

The Hexagonal Household Coal Briquette burned slowly, the heat gathered, and the fire gradually became vigorous.

Du Qi couldn’t wait. After asking Liu Jian to take a wok and put it on it, after it was filled with water, Du Qi asked Liu Jian to take a fan and place it on the air vent. , The constant fan wind in.

As the cold wind blows in, the bottom layer of Hexagonal Household Coal Briquette burns quickly. With increased firepower, the Hexagonal Household Coal Briquette on the lower layer quickly turned red, releasing fierce heat, and even the Hexagonal Household Coal Briquette on the upper layer began to ignite.

Firepower has become more and more prosperous.

Not long, Liu Zhengxi, Guo Xiaozheng and the others entered together. The six people arrived in the backyard. Although the wind and snow are heavy now, they are fine in the house and will not be affected by the wind and snow.

Six people looked towards Du Qi, especially when they saw Tang Zhongsheng and the others there, and also saw the Hexagonal Household Coal Briquette stove, they all looked strange.

What’s the situation?

Liu Zhengxi knows Du Qi’s disposition, especially knows that Du Qi is good at making some new things. He knows that there are craftsmen, so it must be Du Qi’s guide to create new objects.

Liu Zhengxi opened the mouth and said: “His Royal Highness called us together because what new item has been researched out?”

Du Qi said: “There is indeed a new item. It can be used to boil water, cook rice, and cook.”

While talking, Du Qi squatted down through the gap under the iron pan and looked into the Hexagonal Household Coal Briquette stove. Under the iron pan, the flames were already burning, and the firepower of the upper and lower levels was not weak.

Frying and cooking are all possible.

Everyone is puzzled.

Can’t figure out what is happening.

Du Qi didn’t give too much explanation, he was directly instructed: “Liu Jian, bring your various utensils and fry a dish at will. Although it is cold winter, it is still operable.”

“Yes!”

Liu Jian responded immediately.

He also wants to try firepower. After all, this Hexagonal Household Coal Briquette cooktop is also good.

Du Qi’s eyes are full of expectations, because the following Liu Jian demonstration will make everyone realize the benefits of the Hexagonal Household Coal Briquette stove and the convenience of the Hexagonal Household Coal Briquette stove. There is a Hexagonal Household Coal Briquette stove, as long as you are willing to spend a small amount of money, whether it is boiling water, cooking rice, or stir-frying, it can become more convenient.
