Chapter 61

How long has it been? And it's only in this open environment that the fuel reaches such horrible temperatures.

It's almost comparable to the extreme temperature of charcoal burning in an ironmaking furnace! I believe that if you put it into the ironmaking furnace, and then increase the wind into it, I believe that this will definitely make the black iron melt.

Li Tiezhu bowed to Zhao Fengnian and said, "little Lord, this is called the burning of coal. The temperature is really high. I believe that we will be able to bring good news to the little Lord soon."

Zhao Fengnian listened to Li Tiezhu's words and nodded with satisfaction: "well, that's good. I'm looking forward to your good news! In addition, the coal mine can be sold after mining. You can discuss the price and order it again. It should be lower than charcoal, so that civilians can use it. "

After a pause, Zhao Fengnian continued: "well, I have a drawing that can be made of black iron to make a coal furnace, which can better utilize the heat of coal and prevent the gas generated from it from polluting the room."

With that, Zhao Fengnian took out a drawing from his arms, and Li Tiezhu, including Wang Mengtao and an Du, took a close look at it.

In fact, this is a common coal stove in Zhao Fengnian's previous life. The iron stove can lead the gas and smoke to the outdoor with a smoke pipe wrapped in iron sheet.

Zhao Fengnian didn't want to use this when he renovated the shop, but now it's very difficult to make pipes and seals. He can only build a flue as high as the furnace, which takes up space in the shop and is not beautiful.

However, if you use it at home, this kind of coal stove can be used. In this way, not only can the black iron workshop generate income, but also can promote coal so that there is more demand for coal.

"Remember that the outer wall of the furnace must be thick, and yellow mud should be applied inside, otherwise it may be burned!"

"In addition, the smoke pipe can be built-in or external, but attention must be paid to building a good flue, and the indoor air circulation should be often ensured. This, like charcoal, sometimes produces toxic gases."

"And its price should not be too high. To make it affordable for the common people, you can also make various types, use different materials, or make articles on the surface, such as surface grinding and polishing. I want to sell them to the nobles."

Having said this, Zhao Fengnian took out a drawing from his arms and handed it to Li Tiezhu. He continued, "in addition, there is also a drawing to be made by Mr. Li alone. The material is best made of copper, and this needs to be kept secret. We will send someone to deliver it to our house."

Several people listened to Zhao Fengnian's speech, feeling in their hearts, moved inexplicably, the little Lord is really kind-hearted people, even think of civilians everywhere.

All of them are civilians. They know the hardships of civilian life. At the same time, they are glad that there are good lords like Zhao family in the territory. They think so for them

"Yes, I will obey the order of the little Lord!"

Zhao Fengnian was startled by the voice of several people responding in unison. He looked strangely at the red faced and excited people.

But he didn't think much about it. Maybe it was baked by fire

"Well, it's getting late. I'm going to go back. I'm going to bother the Li family first. Brother Wang still has a lot of things to prepare. Maybe he can come and help you in two days."

Several people repeatedly said that it was their own duty, no trouble and so on. With the Li family's escort, the three got on the carriage and went back home.

Back in the territory, it is getting late. Wang Meng and Tao an are both busy with their own affairs. They have many tasks and are short of time. They need to use all their free time.

Although it will be very hard, they are all full of energy and work hard for the visible future. Not everyone can have it.
