In modern rural areas, almost every household has a biogas digester. As long as there are sufficient raw materials in the biogas digester, it can basically provide the fuel used by a family of three to five people for cooking every day.

With current industrial technology, it is naturally impossible to make a biogas stove, but you can still try biogas lamps.

At present, if you want to make a biogas lamp, the first thing to solve is the problem of the air pipe.

The function of the air guide pipe is mainly to transport the biogas generated in the biogas digester. Therefore, the air guide pipe must be resistant to high temperatures and anti-corrosion. It can be said that the biogas pipe is the lifeblood of the biogas digester.

If the materials are improperly selected, accidents such as leakage and breakage may easily occur.

Therefore, it is best to use seamless steel pipes for air ducts.

This is also the reason why she refused to try it at first, because with current technology, it is simply impossible to create seamless steel pipes.

She just wanted Xiaohu to give it a try, maybe he could succeed?

After hearing Lu Yunluo's plan, Xiaohu was silent for a long time, and finally took Lu Yunluo to the northwest side of Donglan College. This place was an open space when Lu Yunluo planned it, but now there is a glass house here.

Lu Yunluo took a closer look and saw that various off-season vegetables had been planted in the glass house.

Isn't this the glass sunroom she wants to build in Leng Gong?

These old men and students can do it!

Everyone knows that greenhouses are used to grow vegetables in winter!

"Sister, look, is this the biogas lamp you are talking about?"

Xiaohu turned on the switch, and the lampshade hanging high in the glass room lit up.

Lu Yunluo was stunned!

"This is one of the graduation works of the last class of Zhou students. It's a pity that he prepared for two years and finally only made this biogas lamp. The biogas stove in the book was not made after all."

Xiaohu's tone was a little regretful.

I heard from a junior student that if biogas stoves can be made, it will be more convenient for people to cook in the future.

Lu Yunluo:......

Well, she almost forgot that the students at Donglan College are all geniuses with high IQs!

It’s not too much to make a biogas lamp according to the drawings in the book, right?

However, Lu Yunluo was still very curious about how Junior Zhou did it. You must know that apart from seamless steel pipes, biogas lamps are also difficult to make.

Whether it is the nozzle of the biogas lamp or the gauze cover that needs to be soaked in thorium nitrate, there is a certain degree of difficulty.

In particular, thorium nitrate must be extracted from a mineral called monazite, which is the key to the ability of biogas lamps to glow at high temperatures.

Xiaohu answered Lu Yunluo's question patiently.

The first is the problem of seamless steel pipes. Although it is true that current industrial technology cannot make seamless steel pipes at one time, welding technology can be used to join them. For example, two separate parts of the main body can be connected to each other through two or more castings.

Together.

Although the efficiency is a bit slower, a seamless welded steel pipe can still be obtained.

It's no wonder that Lu Yunluo doesn't know this welding method, after all, she is not really engaged in this industry.

Once the seamless steel pipe is solved, the problem of the air guide pipe will naturally be solved.

As for how to extract thorium nitrate, I heard from Xiaohu that Junior Zhou had to conduct countless experiments before he succeeded. Now that he has graduated, he has been staying in the laboratory of Donglan College and refuses to leave.

Lu Yunluo couldn't help but sigh at how powerful this junior classmate Zhou was, and guessed that this junior classmate Zhou might have some talent in chemistry.

When he was telling Xiaohu that he would take her to meet this junior student later, a tall and thin male student of fifteen or sixteen years old passed by not far away, walking towards here with a bucket in his hand.

After seeing Xiaohu, he said hello very politely.
