I'm a marquis in Datang

When it is no longer in use, the bottom vent only needs to be covered with a cover. The briquette lacks air to enter, the oxygen content is reduced, and the combustion speed is greatly slowed down, which can play a closed role.

Such a briquette cooker may have a hole in the center for accommodating a briquette.It can also be double-holed or triple-holed to accommodate multiple briquettes to form different firepower for combustion.

There are different classifications in Du Qi's design drawings.

After Tang Zhongsheng looked at it, he said: "Your Highness, this is very simple, not complicated. After all, such a shape is like making a mold. We can finish it tomorrow at the latest. After the stove is dried, we will deliver it. "

Du Qidao: "I am waiting for your good news. When the time comes, I will demonstrate the use of briquettes. The appearance of this briquette stove is a good thing."

Tang Zhongsheng and Wang Wenkai were confused and didn't understand much, so they could only take one step at a time.They completed Du Qi's arrangement first, and the follow-up experiments will be done after the production is completed.

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

Du Qi had a smile on his face.

The appearance of coal stone is equal to a beginning of resource utilization.Although this is the most common use of resources, as long as many things have a little influence, they will gradually be extended, and more and more things will be extended.

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

Early in the morning, Tang Zhongsheng and Wang Wenkai came and brought a briquette stove.This briquette stove is directly made of three-hole briquettes, and the inner tank of the stove contains two layers of briquettes, a total of six briquettes.

Du Qi looked at the stove that was delivered, and ordered people to invite Liu Zhengxi, Guo Xiaozheng, Jin Wuque, Yu Deshui, Yuan Yin, and Yi Fusheng to come, and at the same time asked Liu Jian to set fire to the briquettes that had dried up last night.

It is also easy to ignite the briquettes, and the three briquettes are at the bottom.

This is ignited.

And put it on the iron bar, it can contact the air and continue to burn.Because the bottom is a [-]-degree corner hole, which is the ventilation hole under the briquette stove, and it is also a closed hole.

s position.The briquettes below are burning, and three briquettes are placed on the upper layer, and a total of six briquettes are in the briquette stove.

The briquettes were burning slowly, the heat gathered, and the fire gradually became stronger.

But Du Qi couldn't wait any longer. After asking Liu Jian to take an iron pot and put it on it, and filled it with water, Du Qi asked Liu Jian to take a cattail fan and keep fanning it in at the ventilation hole.

As the cold wind blows in, the bottom layer of briquettes burns rapidly.As the firepower increased, the lower layer of briquettes quickly turned red, releasing fierce heat, and even the upper layer of briquettes began to ignite.

The firepower is getting stronger and stronger.

Not long after, Liu Zhengxi, Guo Xiaozheng and others entered together.The six of them 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.

The six of them looked at Du Qi together, especially when they saw Tang Zhongsheng and the others, and also saw the briquette stove, all of them had strange expressions.

What's happening here?

Liu Zhengxi knew Du Qi's temperament, especially Du Qi was good at making new things.He knew that there were craftsmen, so it must be Du Qi's guidance to make new objects.

Liu Zhengxi said: "Your Highness called us together because of the

What's new? "

Du Qidao: "There is indeed a new item that can be used to boil water, cook rice, and cook."

While talking, Du Qi squatted down and looked into the briquette stove through the gap under the iron pot.Under the iron pot, the flames were already blazing, and the firepower of the upper and lower floors was already very strong.

Frying and cooking are all possible.

Everyone is puzzled.

Can't figure out what's going on.

Du Qi didn't explain too much, and directly ordered: "Liu Jian, bring your various utensils and cook whatever you want. Even though it's cold winter, it can still be operated."

"Yes!"

Liu Jian responded immediately.

He also wanted to try the firepower, after all, the briquette stove was also good.

Du Qi's eyes are full of anticipation, because Liu Jian's demonstration will make everyone realize the benefits of the briquette stove and the convenience of the briquette stove.With a briquette stove, as long as you are willing to spend a little money, whether it is boiling water, cooking, or cooking, it will become more convenient.

Chapter 750

Dismal management

Liu Jian's wok is special.The iron pot that was previously placed on the briquettes was not suitable.So he replaced a frying pan, and the frying pan rested on the briquette stove. Not to mention, the size of the briquette stove was just right.

A pot was placed on it, and as the heat surged up, the bottom of the pot quickly boiled, and green smoke rose from the country.

Drops of water on the bottom of the pot dissipate quickly.

Liu Jian followed the order of his cooking, skillfully poured oil, and started frying eggs. This is the simplest step of fried rice with eggs.

For Liu Jian, at his level, it is not only the understanding of the procedure, but also the control of the oil temperature and the size of the fire, all of which Liu Jian cares about.

As soon as he started doing his own thing, he was immersed in it, forgetting about things and me.

Egg fried rice is out of the pan, full of aroma.

Only then did Liu Jian come to his senses. He looked at Du Qi with a smile on his face, and said, "Your Highness, this briquette stove is really useful. It's even better than a firewood stove."

"Because when the briquette stove burns, there is no smog, and it won't smoke people. And the firepower is enough, cooking is no problem at all. Even the rhythm of cooking will not be affected, so cooking and boiling water will also be unaffected. "

Liu Jian said: "Your new gadget is really easy to use."

Du Qi smiled and said, "Now you understand."

"Understood!"

Liu Jian nodded hurriedly.

He looked at the briquette stove with liking in his eyes, because it was so convenient for him.According to this situation, he doesn't need anyone's assistance to cook, even if he can do it himself.

As usual, because the fire in the firewood stove needs to be controlled, he can't do it by himself. He needs someone to light the fire, and the fire must be well controlled, so it's not easy.

Now with honeycomb stoves, everything is much easier.

This is good stuff!

Jin Wuque was born as a businessman and had an extremely sensitive eye.The benefits of this briquette can be seen at a glance.He said, "Your Highness, what exactly is this?"

Everyone looked at Du Qi with doubts in their eyes.

After all, Du Qi never explained.

Du Qi said: "The stove on the outside is called honeycomb coal stove. The one burning inside is called honeycomb coal because it resembles a honeycomb and has holes."

Jin Wuque said: "What is the cost of this briquette stove, and what about the cost of briquette?"
