The Great Industrial Ming Dynasty Started from Beiping

Chapter 142 Coking by-products

"Crash."

At the end of the meeting, the audience burst into warm applause.

Amid the applause, Zhu Gaochi left the venue, and several clerks in the clerk room followed behind him, and people turned their eyes away from the gate.

"It's sputtering."

As people got up, the sound of tables and chairs being driven could be heard.

The military attache goes first.

Then came the shopkeepers, and finally the stewards.

The military households and military officers of the Yanshan Guards are very familiar with the factory, and the two sides have cooperated for a year, and there has been no barrier between them for a long time.

As for honor and inferiority.

The little prince doesn't talk about dignity, and the highest position present is only a thousand households. Who dares to talk about dignity in China Heavy Industries?
Power is what matters.

Qiu Fu pulled Zhou Shifeng past him, startled Zhou Shifeng, and Zhu Neng who was passing by saw him and stopped.

Qiu Fu ignored Zhu Neng, knowing that this kid was worried that he would bully others, but the person in front of him was the big shopkeeper of China Heavy Industries.

Even if you bully someone, it depends on your status.

"The chemical fertilizer said that it can increase the grain by more than one hundred catties per mu. Is this true?" Qiu Fu couldn't believe it.

"It's true." Seeing that Qiu Fu couldn't understand, Zhou Shifeng pointed out with a smile, "You treat chemical fertilizer as concentrated farm manure."

With such an explanation, Qiu Fu understood.

"Sell me some of this fertilizer."

Zhou Shifeng glanced at Zhu Neng, saw that everyone around him had finished walking, and whispered to the two of them: "The fertilizer production process is still being optimized, which is in the exploratory stage, and it will take some time before it can be put into production."

"However, as far as I know, this item should not be sold outside."

Hearing this, Qiu Fu didn't say anything anymore.

The little prince must be willing to not take out food, so he gave up his plan for chemical fertilizers.

"It should be treated as an internal benefit and distributed to outstanding workers."

"What about us?" Qiu Fu asked quickly.

Zhu Neng also took a step forward.

Zhou Shifeng showed a smile, and said with a smile: "The little prince is the most important military household, how can he forget the two, although there is no charter yet, but there is no need to worry."

That's true, the little prince never treats military households badly.

"I'm not greedy for the benefits of chemical fertilizers." Qiu Fu put Zhou Shifeng on his shoulders, and Zhou Shifeng shook his head helplessly.

He wasn't afraid of Qiu Fu, but he knew that Qiu Fu's character was like this, and it wasn't to make things difficult for him. To be precise, it was Qiu Fu's act of showing intimacy.

Seeing that nothing happened, Zhu Neng left.

When Zhu Neng's figure faded away, Qiu Fu smiled and said: "I'm a big boss, I speak straight to the point, brother Zhou, don't take offense, you are not a military household, you don't know our way."

"Wars will kill people. You must have trustworthy brothers. I have a group of brothers who can work hard. How can I be greedy for the profits of chemical fertilizers? It's just for my brothers."

Zhou Shifeng suddenly realized.

Whatever you do, you need someone to support you.

The same is true for him. The factory cannot run without a helper in charge.

Li Er's technology is not as good as Wang Ben's, and his position is not as good as Wang Ben's, but he still has an equal share with Wang Ben in the coke refinery.

What he relied on was a group of fellow villagers who supported him and did not discount his words in the slightest.

This has been the case since ancient times.

The cafeteria provided a wealth of food, but Zhu Gaochi did not participate.

Factories must not only provide benefits for workers, but also pursue efficiency.

It is not only a huge waste, but also a waste of time for the government to do one thing. This habit does not exist in China Heavy Industries.

Both military households and civilian households must reverse their concepts and accept the factory culture of China Heavy Industry.

People who were full left the factory in groups and came to the China Heavy Industry Station on the railway.

"Crack clap."

The railway carriage is parked at the station and has two carriages.

The red and green paint on the carriages looks bright and beautiful, and it is specially used for riding.

The carriages for bulk coal are primary colors, and the rest of the commodities are white.

Eye-catching colors are used so that people can see them from a long distance, and the bell on the driver's side reminds passers-by not to trespass on the railway.

People on the site, with the tickets provided by China Heavy Industry, can ride this carriage for free.

In the rectangular carriage, on both sides of the aisle, there are rows of fixed wooden chairs. There are five rows in total, with two people sitting in each row, and a total of four people on both sides.

There are 20 people in one train and 40 people in two trains.

After everyone was seated, the coachman rang the bell.

"Jingle Bell."

Everyone sat down one after another. Everyone present had ridden on a railway carriage, so they didn't make a fuss, but they still looked out of the window curiously.

The small station outside the window was no longer visible. On the side road, there were passers-by watching the railway curiously.

When encountering pedestrians who are close to the railway, if they do not turn back, the driver will ring the bell to remind them.

Pass a village.

The children in the village ran out one after another, yelled and yelled at the railway carriage from a distance, followed them for a while, and were thrown farther and farther away.

"I have ridden the railway carriage no less than ten times, but every time I ride it, it still surprises me." Zhang Fu, who was leaning against the window, sighed.

The military officer next to him didn't answer, he just closed his eyes and rested his mind, thinking he was asleep without knowing it.

The military attache in the railway engineering team, because of working together, has a tendency to cling to each other, but no one is willing to pester Zhang Fu.

Because this person is the son of Zhang Yu, the commander of the left guard.

Zhang Fu didn't take it seriously, he was used to it, just as the eldest son said, the environment changes people, and sooner or later he will also be Yanshanwei's own.

half a month later.

The land enclosure movement that started in the second half of last year has ended the first phase. Whether it is the railway project or the expansion of honeycomb coal, with the power of the Yan Palace, the plan has been perfectly achieved.

Next, the railway project only needs to be buried in road repairs, and honeycomb coal only needs to be fully produced.

In the next stage, Zhu Gaochi will let China Heavy Industry practice hard.

Wansan was in charge of the technical guidance of the Miyun division, so he was unable to take care of the R&D department in Beiping, so he resigned from the R&D department.

Wang Ben was promoted to be the chief steward of the R&D department, Xiao Jiu and Li Er were the stewards.

Wang Ben is in charge of checking the general direction, while Xiao Jiu and Li Er are in charge of the specific affairs of the R&D department.

There are already 30 craftsmen who have entered the R&D department to experiment with their own ideas, plus general workers and handymen, the scale is a department of [-] people.

However, Zhu Gaochi did not appoint a steward, and this department is full of craftsmen from top to bottom.

The R&D department is a flat department.

"During the coking process of coal, because the coal kiln and combustion are not separated, the dry distillation of coal produces gases such as gas and methane."

"These flammable, explosive and toxic gases are very dangerous."

Zhu Gaochi taught the craftsmen of the R&D department.

Because of the limitations of ancient technology, it was directly burned in coal kiln at the beginning of its birth to provide heat source for coking.

With the advancement of technology, in modern times, coal kilns and combustion chambers are completely isolated.

When the temperature is [-] degrees, the gas and methane can reach the maximum value, and then continue to raise the temperature to [-] degrees, perform a second high-temperature dry distillation, and use the recovery system to collect.

Therefore, in the eyes of later generations, the ancient coking technology wasted gas and methane, which is a great waste of resources.

But everything has two sides.

In Zhu Gaochi's view, under the conditions of ancient times, the technology that was backward in ancient times compared with later generations just met the needs of the times.

If these born gases are specially collected as in the later generations, the safety cannot be solved, and one explosion will cause heavy losses.

So collecting gas and methane, Zhu Gaochi did not have this idea.

The coking technology of the coke refinery leads to burning these gases into the coke kiln. Although these resources are wasted, the hidden safety problem is solved.

The advancement of technology is also accompanied by dangers. The steps must not be too large, but must be taken step by step.

Zhu Gaochi has a clear understanding of this, so the factories he set up have no qualitative development except for the scale.

Most of them are based on the technology of the ancients, expanding the scale, concentrating production operations, and using the advantages of large-scale production to crush the production efficiency of workshops and improve social productivity.

"In the process of coal coking, the gas produced, including flammable and explosive gases, although it has been burned, there will still be various residual gases."

"Ammonia and soot are among the gases."

"A small amount of ammonia gas and oil fume are discharged from the chimney directly above, and most of them are discharged from the air outlet above the side."

"Ammonia gas is easily soluble in water. The solubility of ammonia gas in water is very high. [-]% of water can dissolve [-]% of ammonia gas."

Everyone thought hard about what the little prince said was flammable and explosive.

They believe that the high temperature in coking is mainly due to the role of coke itself, but according to what the little prince said, the role of gas is not small.

As for the explosion.

Coking technology has been born for hundreds of years, but I have never heard of anyone's coke workshop ever exploding. The little prince said it was because of burning.

There are so many unseen things that the craftsmen are a little confused.

However, the young prince is like a godsend, pointing out a lot of theories, no one thinks he is talking nonsense.

Oil fume is heavier than air, and after cooling, it forms tar, which accounts for [-]% of the coal load. It is the same as kitchen range hoods in later generations, leaving a large amount of oil after cooling.

After the explanation, using the properties of these two gases, Zhu Gaochi, Xiao Jiu, and the craftsmen of the R&D Department fumbled for several days.

Under Zhu Gaochi's guidance, between the two coal kilns, fired bricks were used to form a flue at the tuyere of the coking coal.

Several openings are opened directly above one section of the flue so that the remaining gas mixed in can be discharged.

Between the two coal kilns, a hollow platform was built with bricks, on which a huge tin can was held.

One side is an iron pipe for water intake, and the other side is also an iron pipe for drainage.

Ammonia and oil fumes enter the iron pipe through the flue, and then enter the iron tank from the iron pipe. The water in the iron tank provides cooling.

Ammonia gas dissolves in water, and tar is formed after the oil fume cools. Tar is heavier than water and deposits at the bottom.

There is a water outlet on the top of the tin tank and an oil outlet on the bottom.

The water that comes out is ammonia, and the oil that comes out is tar.

According to the experiment, take ammonia water every half an hour and refill it with clean water.

Tar belongs to light tar, which is close to the specification of light diesel oil. After continuous distillation, diesel oil, kerosene and other products can be obtained according to different degrees.

Then from the coke kiln, coal black can be collected directly, and the bitumen obtained after the dry distillation of some oily matter.
