With mud added to this, can it really be burned? "
Li Yuanji knew that coal could be burned, but he also knew that mud could not be burned. Therefore, he did not know whether coal and mud could be burned when mixed together.
"It can be burned, but since it's just done, there's still a lot of moisture in it and it's very smoky."
Li Yuanji didn't care about this, he just wanted to see how popular this thing was.
Two guards were called and they lit the fire below with a firewood stand. Tang Ping held the honeycomb briquettes with an iron tong. After a while, black smoke began to rise.
"Burned!"
"It's really on fire!"
There were a lot of people gathered here today, because the proprietor said he was making fire things for everyone, so naturally they all came to take a look.
Although the briquettes were very smoky, it could be seen that there were already flames.
Tang Ping asked someone to bring over the briquette stove that had been prepared in advance.
This stove is simple to make. It has an air inlet at the bottom and a small sliding door. The flame can be controlled by controlling the size of the air inlet.
There is a two-layer iron grid on top, which is exactly the size of a piece of briquettes. When the briquettes are placed on it, it will be filled up.
Tang Ping brought a kettle himself, asked someone to fill it with water and put it on the stove.
Everyone looked at the stove quietly, but after more than ten minutes, the whistle on the spout still made a sharp sound.
"The water is boiling!"
"It's really open, it's burning so fast!"
"Yes, such a small piece of coal can burn so fast."
"How long can this piece of coal burn?" Li Yuanji waved his hand and fanned the smoke. The smoke was indeed quite strong.
"If the air outlets below are fully opened and the wind is strong, it can burn for more than an hour." Tang Ping also estimated based on experience: "If there is no wind, let it simmer down slowly, it can last for an hour."
As he spoke, he used iron pliers to open the small door where the coal was placed, and pointed inside: "The top one is almost finished burning, so put the lower one, and then put a new coal cake on the top one and continue burning."
He took out the coal and carried it with the handle that came with the stove: "Bring two pieces of coal, it's about the same size. It's easy to carry anywhere."
"This stuff is awesome!"
"Thanks for being our proprietor!"
"Just fan the cigarette with a small fan and it will make the fire burn bigger."
"No

Well, from now on we can just lift the stove to the edge of the stadium and cook food. If we cook it in front of those people, they will feel more at ease while eating. "
Seeing Tang Ping's demonstration, all the people in Shanghe Village became excited. With this thing, they even save the time of going to the mountains to chop firewood, and they can do many other things.
"But I have to say something!" Tang Ping suddenly became serious: "You cannot bake food directly on the fire of this stove. The smoke is poisonous, so you absolutely cannot burn it in a closed room. Do you understand? Otherwise, people will die. of."
Seeing Tang Ping's solemn words, everyone nodded. The villagers in Shanghe Village knew that there were two things Tang Ping cared about most, one was the children in the village, and the other was safety.
"Third uncle, when you want to sell this stove, you must make it clear that it must not be used in the room."
It's okay that the weather is warm now, but Tang Ping is afraid that when it gets cold, some people will use the stove for heating at home while sleeping, and that will cause big trouble.
Of course Tang Ping could add a flue at the back and seal it a little tighter so that the burning smoke can be discharged through the flue.
But with the current level of forging, it is not easy to make a thin iron sheet for the flue. In the end, the cost of the stove will be increased a lot, which defeats his original intention of building the stove in the first place.
Of course, Li Yuanji knew that what Tang Ping said was right, and nodded in agreement.
Starting from today, coal will gradually be transported from the mine and then pressed into briquettes here.
It would be cheaper for people in Shanghe Village to buy here. Tang Ping had calculated that compared with burning with coal and chopping firewood, it would be much cheaper if the time cost was included.
As for the excess briquettes, of course they were sold to Chang'an City. They were not used by wealthy families, but they were definitely suitable for ordinary people.
When the time comes, there will be a briquette shop in Chang'an City, which will sell both coal and stoves. If people want to make it cheaper, they can spend some time and effort to buy briquettes in Shanghe Village.
Tang Ping and Li Yuanji didn't care who tried to imitate and sell this stove. Anyway, a stove can be used for a long time after being bought, and the main money making is from the briquettes.
Others cannot buy coal, and are not afraid of being robbed of their business, so they can continue to do so for a long time.
And there is no need to advertise this thing at all. Wang Tieniu built a batch of briquette stoves for the villagers, and the villagers of Shanghe Village carried them to the edge of the stadium.
(This chapter is not finished, please turn the page)
Those watching the game and other people who came to sell food nearby saw it.
The first people to place orders are those people who come from other places to sell food. As long as they buy this stove, they can also cook food outside the stadium, thus narrowing the gap with the villagers in Shanghe Village.
Tang Ping didn't have any objections to this. Although Shanghe Village was his territory, it wouldn't hurt them if someone competed with them.
To be honest, the residents of Shanghe Village do not rely on selling these food to live, but just to subsidize some household expenses.
Soon, many people in Chang'an discovered the benefits of this kind of coal stove. If you only cook at home, you can close the stove after finishing cooking at noon, and you can still use it when you open it at night. It only takes one piece of coal a day, including buying firewood. Not much different.
Some people are more frugal. After cooking at noon, they put out the fire immediately and wait until evening to light it again. A piece of coal can last two days.
Of course, this will definitely affect the livelihood of the people who sell firewood and carbon, but Li Yuanji quickly called these people over.
It takes people to transport coal from the coal mine to Chang'an, and it also takes people to make coal slime and press honeycomb briquettes in Chang'an.
There were still more, so he simply threw them away and built a road from the mine to Chang'an. The materials used to build the road were cinders after burning.
Those who are buying briquettes can buy new briquettes at a cheaper price if they take the burned briquettes to the coal store.
All these burned coal cakes are crushed and used to pave roads. This kind of road is paved quickly and is much easier to use than dirt roads. At least when it rains, it will not become muddy.
In the end, all the coal produced in this small mine was taken away by Li Yuanji before it was enough for the consumption of the people of Chang'an.
Of course, it was not that there were no ministers in the court who expressed their opinions, saying that this was King Zhao using the country's assets to make money.
But when the Ministry of Industry took out the sales form, this voice became much quieter.
Because Li Yuanji's price for buying coal is higher than that of official kilns and metallurgical factories.
Then, after the Ministry of Civil Affairs took out the tax payment records of the briquette store, no one made an issue with it at all.
It is equivalent to the coal mine output that could only be sold for 100,000 yuan. Now with taxes, King Zhao gave him 110,000 to 20,000 yuan.
It can be regarded as generating revenue for the national treasury.
