"Only Zhaoxian coal..." Zhang Yifu was thinking about it and had to re-released the knowledge of coal mixing that had been prepared for dust. He mentioned it to Lao Niu at the last meeting, but because the project was too large and the best coal supply was already available, he gave up. Now it seems that Lao Niu is blindly optimistic, or Zhang Yifu is far-sighted and has been prepared for hard work.

Coal mixing is a terrible thing. Zhang Yifu wanted to vomit just after seeing those formulas. Even though he still remembers some of the edges and corners in advanced mathematics, these formulas are still like oracle bone inscriptions.

Thank you for your hard work for your academic career, so I'd better get the results directly.

Although the calculation of coal mixing is very complicated, the principle is very simple. It is to mix secondary coal and good coal together to burn it, so that good coal can drive the combustion of secondary coal. Of course, one plus one is impossible than two. This method is just to give the secondary coal a little force.

For the word "powerful", Chinese and foreign experts have worked hard for decades of research, calculation and experiment. Finally, today, this result can be brought directly by Zhang Yifu.

Specifically, there is no calculation result for Urum coal and Zhaoxian coal, but some people have obtained the results of matching 5,000 kcal and 4,000 kcal coal types ten years later. Compared with other factors such as boiler model, particle size, volatile content, etc., Zhang Yifu finally found a suitable practical result. Thanks to a power plant 18 years later, and to your scientific power coal mixing engineers.

According to that result, if the supply of high-quality coal is not considered, the 3:1 mixture of Urum coal and Zhaoxian coal is the most economical, but there is so much Urum coal at present. Based on many actual situations, from the many plans given by the research results, 1:4 mixture is the only choice for the Jibei Power Plant. Use a small amount of good coal to drive the secondary coal to burn fully, and try to improve the efficiency of the boiler and powdering system.

Since the data and results of senior experts are here, Zhang Yifu naturally has a clear idea.

"Maintain, please be qualified." He said, extinguishing the cigarette butts.

"What's the right thing?" Niu Dameng obviously didn't think about it at all.

"Make coal."

“How to match?”

“One to four.”

“…How did you know?”

"You really want to know how I know?"

"I really want to."

In desperation, Zhang Yifu asked for paper and pen and began to calculate in front of Niu Dameng. Of course, he did not do any calculations. He just copied the calculations of later generations.

Seeing those damn symbols, Niu Dameng's head exploded directly.

"Enough is enough..." Niu Dameng looked at something wrong and quickly stopped, "Yao... I am not questioning your theory, but there are too many factors to consider during the coal mixing process. You can't do it easily. Maybe it's not worth the effort."

"Don't worry, factory manager, let's continue to see that the slag-making characteristics and powder making consumption have also been taken into account. Look, I'll calculate it for you..."

Niu Dameng looked at it for another two minutes and was completely dizzy.

"Okay...Okay..." He said repeatedly, "Coal mixing... After all, it is a big project, and we have to apply to our superiors for early supply of coal. And this theoretically valid thing may not be true. Yifu, let's seek stability this time."

"Manager, you can practice it first," Zhang Yifu said immediately. "The model of Unit 3 and 4 is exactly the same as the production period, and the boiler is also equipped with the same configuration. We will know after a week of experimenting!"

"..." Niu Dameng looked at Zhang Yifu, and this time he really didn't know where he got his confidence and confidence.

In this era, coal mixing was usually caused by the inability to burn inferior coal and was brought with it with good coal. The theory about coal mixing was just a prototype. As the director of Niu Dameng Niu, who was unable to solve quadratic equations, he naturally could not understand this magical process and had no mentality. In short, he did not believe that coal mixing would improve the efficiency.

"Yifu, even if it's just a test, the workload is very large. I have to adjust a lot of things. I'm afraid the fuel workshop can't stand it." Niu Dameng still wanted to reject this proposal and continued, "Besides, this is something that is done by a doctorate and master in the Academy of Electrical Sciences. Our power plant cannot afford it..."

"Our power plant is the first power plant in the country to build." Zhang Yifu directly threw out Niu Dameng's favorite thing, the cake that has been tried and tested. "The factory director, it's really not that troublesome to test two units for a week, and Fu Bo just said that he would support whatever he asked him to do."

"Oh?" Niu Dameng was shocked, "Can Fu Bo say this?"

In his eyes, Wang Zhenhua is an old stubborn person, and Fu Bo is a little stubborn person. These two are probably the two who are most comfortable in the factory. Why did they suddenly take the initiative to find work?

"It's because the enthusiasm of the entire factory has been rising recently, and Fu Bo doesn't want to fall behind."

"That's right, this kid also knows that he has made progress." Niu Dameng nodded quite satisfied, but he still didn't let go of the matter of coal mixing.

What to do if you can't make up your mind?

Let others make up their minds.

"Let's do it." Niu Dameng waved his arm, "You go and talk about this to Lao Duan. He can understand the formula. If he nods, you can make a report and ask him to sign it. I will agree to the test."

So, it is not that difficult to be a leader. All disgusting things are just to be honest people like Duan Youwei.

A few minutes later, at the old desk, Zhang Yifu started painting cats again.

But Lao Duan was also having a headache when he saw these ghosts. It was really hard for Lao Duan to understand the difficulty of his master's thesis more than ten years later.

But Lao Duan was embarrassed to admit this. After all, he was an academic, not a rough one.

So he had nodded frequently.

"Well, that's how it is calculated."

"Is this outlet temperature okay?"

"No, not bad, should we use a calculator here?"

"Okay... OK."

In the end, Lao Duan was also timid, and like Lao Niu, he waved his arms with annoyance: "If it does not affect safety or production, then try it. You can report it, I will sign it! Isn't it okay for me to sign it!"

This situation simply turned into Zhang Yifu urging the two leaders to work. If he hadn't had all the brilliant achievements first, no leader would have been able to stand this.

Starting a report, following the process, signing, writing plans, and having a meeting, Zhang Yifu was enriched again this week.

But the coal mixing matter is too rude and stingy. Everyone can only be timid and do whatever you ask me to do. I can't help too much. This time, even Duan Youwei can't say anything.

There is no way. Even in this era, coal mixing is a magical thing.

The Americans have many resources and don’t have to worry about it. Their coal distribution is mainly to reduce sulfide emissions, so that they can overcome the environmental protection indicators stipulated by various associations.

Little daily resources are small and you have to import them. The main purpose of mixing coal is to save money, save transportation costs, save energy, and save life.

The main reason for the European coal distribution is that the power plant equipment is too old and the update speed is extremely outrageous. It cannot carry secondary coal, so it is a last resort.

Therefore, except for Japan, where there are few lands and people, there is actually no academic term "power coal mixing" in other developed regions, just to solve the troubles in front of them.

In the future, power coal mixing will become a science, with specialized research aimed at both environmentally friendly and economical. In this world, Zhang Yifu may become the big brother who promotes this discipline.

Even the field of fuel thermodynamics was involved, and Zhang Yifu felt that he couldn't do it and couldn't be busy.

Fortunately, he is now under one person and more than ten thousand people. Every word he says is treated as an imperial edict. Fu Bo, who is lazy, dares not delay at all. With the help of other workshops, he made preparations for the test in just a few days. Boilers No. 3 and 4 supply coal, No. 3 is the Zhaoxian coal that has just been sent, and No. 4 is the 4:1 mixed coal from Urum, Zhaoxian.

In fact, in the future, academic masters will develop a software to solve this problem. They just need to type in each parameter on the computer and wait for the result. But at present, Zhang Yifu has to directly take out the result and let others see it clearly, otherwise Niu Dameng would not dare to listen to everything if he believes in himself.

Starting the next Monday, the week-long coal supply test of Unit No. 3 and 4 was launched. Wen Tianming recorded the entire process and wrote copywriting and publicity materials. Zhang Yifu made a good plan. If this matter ended up, this experiment would be a role model and a benchmark. It would not be an exaggeration to publish a book for power plants across the country to learn.

Old cow, old cow, I've been worried about you, why are you so unsuccessful?

This kind of experiment is a long and boring process. The main thing is the boiler and fuel person. The recorded things are also handed over to Wen Tianming, and the rest is waiting for the results. On Monday night, Zhang Yifu could finally relax for a short time and make an appointment with Xiang Xiaofei to eat the familiar and delicious donkey hotpot.

Zhang Yifu has been too nervous recently. He followed the investigation team to Fengzhou, and had to use his brain and keep his strings tight. When he came back, he had to be tense, when facing Lao Niu, Lao Duan, Huang Hongbin and Fu Bo, and even when facing Niu Xiaozhuang, he had to be tense.

Only by being with an older girl can you relax and not think about the pros and cons of any word.

After a few sips of wine, he looked at Xiang Xiaofei and felt comfortable all over his body, comforting his bones, and then putting on the tiger dish...

Life is so beautiful.

If Xiang Xiaofei is not very energetic in this ghost place, she has to spur Lao Sun and his group of people, but she can't leave, which is a waste of youth. Originally, she should have pestered her brother to do this and that every day, but she knew that now was the most important time in her career. If the sky had not fallen, she would never dare to disturb Zhang Yifu.

This time, Zhang Yifu took the initiative to invite him to drink, and she was happy and comfortable.

"Hebei is really boring, I don't even have a friend."

"I told you that the leaders who went to Fengzhou were nonsense. I doubt how they came up!"

"I heard that Niu Xiaozhuang is going to get married?"

"It's been a long time since that girl is still hanging this kid. You can listen to me and finish Fengzhou affairs first, and a sarcastic director came to the department..."
