"Boiler?"

Wang Tiehammer was blinded: "What is a boiler?" I've never heard of this thing. ”

In this private room, there are more than a dozen people, all of whom are technical masters who have a lot of experience in ironmaking and casting, and have designed many innovative and subversive iron processes.

These people are also very obscure about the concept of boilers.

"Dean Yan, what is the boiler for?"

"I've never seen it, this stove is not small, with five floors up and down, and the design is very cumbersome."

"There are also a lot of pipes, twisted and turned, up and down, seemingly ...... Is this thing boiling water? ”

……

Burst!

Boiling water?

Yan Qi Khan: "If you want to say that it boils water, that's fine, but boiling water is just his sideline, a small skill." ”

Wang Tiehammer scratched his head: "What is its main function?" ”

Yan Qi said: "Heating." ”

"Heating?"

Everyone was stunned.

This statement is too novel.

Wang Tiezhu was the most authoritative, observing the drawings for a long time, scratching his head: "Dean Yan, I really don't understand, how can boiling water be heated?" ”

Yan Qi explained: "Remember? In the summer, at night, jump into the pond to take a bath, the water is warm, why is the sun setting, the pool water is still hot? ”

Wang Tiehammer said: "Because water absorbs heat for a long time, it is not easy to get cold. ”

"Yes."

Yan Qi pointed to the boiler drawings: "Master Wang, everyone, come and see, the shape of this boiler is only a few differences from our ordinary stoves, ordinary stoves have stoves, stove barrels, or ondols made of stones. ”

"Here's the problem: Fireworks passing through chimneys or ondols emit heat. However, there is one point, although the stone kang and the iron stove can absorb heat, but it is very limited, most of the heat flies away from the chimney, the heat cannot be retained, the efficiency is low, how much coal has to be wasted? ”

Everyone nodded.

They are all insiders, and Yan Qi's words are a little clear for them.

Wang Tiezhu studied for a long time: "Dean Yan, the ordinary stove we use, just this principle, is indeed a waste of coal, but there is no better alternative." ”

Yan Qi pointed to the drawing: "The efficiency of this boiler is much higher than that of ordinary coal furnaces. ”

Wang Tiezhu was very interested: "Please Dean Yan to come and listen." ”

Yan Qi pointed to the topic in one sentence: "Because, this boiler does not burn smoke."

, but water. ”

"Boil water?"

You look at me, and I look at you, but you still don't understand.

Wang Tiehammer stared at the drawings and thought for a long time, and suddenly slapped the table: "Oh, that's right, boiling water is indeed better and lasts longer." ”

Yan Qi smiled: "It's still Master Wang's professional." ”

He pointed to the drawings and explained: "Guys, you see, the pipes are filled with water, and the heat from the boiler is transferred to the pipes, and the heat does not have a chance to escape from the chimney, but is absorbed by the water in the pipes. ”

"Water locks in a lot of heat and releases it slowly, so it doesn't withstand too much heat and is durable."

"At the end of the day, the advantage of this boiler is that it uses very little coal for sustainable, efficient heating."

Wang Tiehammer slapped the table and laughed: "That's right, it's this Li'er, Dean Yan, you are really amazing!" Even if I were to live for another hundred years, I would not be able to build such a boiler. ”

A group of people are gossiping, and they all come to hold stinky feet.

Yan Qi's face was stinky, his tail was cocked to the sky, and his mouth was still very modest: "Normal operation is just a little trick." ”

Everyone looked envious.

Especially Wang Tiehammer, looking at Yan Qi's eyes, with infinite admiration: I want this kind of little trick too, but unfortunately I don't!

……

In the following days, Yan Qi kept Master Wang busy in the horse farm.

Everyone is keeping it a secret.

No one knows what they're up to.

Even the professors and masters of other disciplines in the Gewu Academy didn't know what Wang Tiezhu was forging.

They thought that Wang Tiehammer was building the fence of the horse farm.

These days, Yan Qi went to the Ministry of Engineering in the morning to order something, and then came back to study the boiler with Wang Tiezhu's team.

In fact, the boiler drawn by Yan Qi is just the simplest design, and in the previous life, it belonged to the primary boiler.

However, in Dahua, it is a subversive existence.

Boiling water for heating is definitely a novelty.

Wang Tiehammer looked at the picture and spoke.

Although the forging technique is very high, the first time you forge this thing, you need to grope your way across the river, and it is not an overnight thing.

It's more than ten days when it's busy.

More than a dozen boilers were built.

They also looked at each one to see which design was more efficient and had a larger capacity.

Everything is going on in an orderly manner.

……

In the Ministry of Industry of Nuoda, a new round of crisis finally broke out.

Tian Heng, the deputy attendant of the Ministry of Works, has become the fat in Jiang Dongqu's mouth, and he wants to swallow it in one bite.

Morning.

Morning meeting.

Xia Ming, the secretary of the Ministry of Works, has always said that he was sick and absent and did not come to the morning meeting.

Jiang Dongqu covered the sky with one hand.

Xiong Fucai and Huang Zhikai, two vicious dogs, stood on Jiang Dongqu's left and right, straightened up, held their heads high, bared their teeth, and looked like they were about to bite.

Yan Qi winked at Tian Heng and whispered, "Lord Tian, you see, these two dogs are very energetic. ”

Tian Heng smiled reluctantly.

He didn't have the heart to joke.

He has already received the message.

Today, Jiang Dongqu is going to operate on him, who can be happy.

Tian Heng was stumbling melancholy, and Jiang Dongqu's eyes stared at him like a sword: "Deputy Squire Tian, I asked you to study the stove and increase heating, is there any progress?" ”

Tian Heng hesitated: "This ...... This ......"

Jiang Dongqu roared angrily: "What are you stammering? Ben Shirou asked you, has there been any progress on the issue of heating? ”

Tian Hengyi shuddered: "No...... There is no ......"

"What an incompetent."

Jiang Dongqu scolded directly: "I gave you twenty days, but you can't even do this little thing, do you have a problem with your brain, or do you take what I said as a deaf ear?" ”

Tian Hengdao: "Jiang Shilang, the reform of the stove is not a small problem, but a systemic problem, very big, very vast......"

Jiang Dongqu slapped the table: "What excuse are you looking for?" Isn't it just a broken stove, given 20 days, and you don't make any progress, which means that you are incompetent, you are derelict in your duties, and you are irresponsible. ”

"You said that you are wearing an official uniform and ranking first among the deputy waiters of the Ministry of Works, but you are so sloppy and procrastinating, is it a shame? An official like you, who eats and doesn't work, has the face to occupy the magpie's nest? ”

When Tian Heng heard this, his scalp was numb.

This is a serious statement.

It's broken.

Jiang Dongqu is going to kill me today, but it's not as simple as punishing me.

Sure enough.

Jiang Dongqu came behind him with a sentence that was neither yin nor yang: "Tian Heng, give you two choices, first, I will play Prime Minister Yang Cheng, wait for Prime Minister Yang Cheng's order, and forcibly drive you out of the Ministry of Industry; Second, if you want to make a face, get acquainted with each other and take the initiative to return to your hometown? Choose one of these two points. ”

As soon as these words came out, the Nuo Da Ministry of Engineering was quiet, and the needle drop could be heard.

Tian Heng's body trembled, and his face turned pale.

Hey, I really can't hide it.
