You should know that the difference between unplanned shutdown and planned shutdown is huge. Except for the planned shutdown arranged by the dispatching, all fault shutdowns, emergency shutdowns, and temporary shutdowns are all classified as non-count stops. The non-count stops of units are one of the safety production indicators. The Electric Power Bureau of the Electric Power Bureau evaluates each power plant according to annual assessments

Zhao Wenyuan sold such a big face and completed such a special process, which was a perfect end to the end, so Zhang Yifu naturally wanted to thank him.

"Director Zhao, preliminary judgment, boiler abnormalities may be related to the change of coal types. Recently, Zhaoxian coal was suddenly adopted, and slag may occur due to boiler and auxiliary machine design standards. We will use the maintenance time to carefully investigate and test it."

"Well, there is no way. The problem with the Inner Mongolia coal mine is not available in North China." Zhao Wenyuan said in a deep voice, "Okay, go and do your job quickly, the bureau is waiting for your report."

"good."

The two of them did not exchange too much greetings, so they were left behind. It must be because both sides were in front of the people in the room, so it was hard to say much.

Zhang Yifu put down the phone and rushed to the squad leader and said, "Please inform the maintenance workshop and electrical workshop, and inform Wang Zhenhua and Fang Hao of the situation. Unit No. 3 will start today and enter the annual inspection."

"……………Okay…” The squad leader was impressed by this courage. Daming was here, and at most it was like this.

After the dust settled, Wang Xiaohua came up and asked, "What's the matter? It's so serious?"

"Wait, I'll go to the boiler first." Zhang Yifu raised his arm and did not give her a chance to get close to him, so he pulled Fu Bo away in a hurry.

"..." Wang Xiaohua was alone and kept stomping her feet, which was so aggrieved.

The young duty officer next to him smiled and said, "Xiaohua, can't you post it anymore?"

"You're looking for death!" Wang Xiaohua wanted to strangle this little bastard to death.

"Okay, okay." Ye Qingqing hurriedly stepped forward and pulled Wang Xiaohua over. There was no choice but to persuade him.

After fermenting for so long, the story of factory flowers posting Zhang Yifu has basically been known. Of course, this is definitely not a rumor created by Zhang Yifu. It is just a matter of Wang Xiaohua's own propaganda.

But we, Zhang Yifu, is a grassroots cadre who focuses on influence. He follows the truth that "love without marriage is just a hooligan" as mentioned by **, and will never mess with relationships between men and women.

Of course, in the eyes of ordinary people, it is simply that Zhang Yifu looks down on Wang Xiaohua.

Where does this give the factory flowers dignity?

Zhang Yifu had no choice but to mess with relationships between men and women, who wouldn't want to? Unfortunately, the power plant is a serious place, with thousands of eyes staring at him, and he couldn't afford it. Rabbits must not be able to eat grass by their nests and can only wait for the opportunity to go out to hunt.

Back to the boiler of Unit 3, Huang Hongbin and Wen Tianming were here to be on high alert.

The shutdown of the power plant is a major event that alarms the entire factory. It is not as simple as pulling a gate. Pulling the gate and tripping is a matter of necessity in an emergency. It not only damages the unit equipment, but also has endless safety hazards.

Normal shutdown operation requires the preparation of shutdown and the sliding parameters to be adjusted. This shutdown and that shutdown is carried out step by step, and it is finally turned off one level after another to ensure safety and equipment integrity.

Even though this time it was almost an emergency shutdown, the boiler still waited for more than ten minutes before it could be operated.

This terrifying and huge big guy, the old guy, can't stop just by just stopping.

Under Huang Hongbin's personal command, the first thing to do was to reduce the heat supply, stop coal and air supply, and slow down the wind. Zhang Yifu was also watching strongly on the side, witnessing this moment. The power plant he was in in his previous life was basically completed by automation, and he had not experienced this scene with his own eyes.

As the fuel supply is stopped, the noise and vibration of the coal supply pipeline gradually decrease and eventually stops, but the induced air fan is still working and the slag discharge is still in progress. It is necessary to ensure that the smoke and ash inside can be sent out.

It took about half an hour to confirm that the fuel was basically burned out. Although the subsequent slag discharge is still in progress and the circulating water system has not stopped, the further ventilation will take six hours to open. The boiler is basically in danger. The only thing left to pay attention to is to prevent the boiler from cooling sharply. If such a big guy cools too quickly, resulting in serious abnormalities in pressure and material, the degree of damage to the equipment will not be less than that of an explosion.

At this point, this large metal mass that had been working continuously for nearly a year has slowly faded out. Although the furnace cannot be seen, the process can still be felt, which makes people feel an inexplicable feeling.

But at this point, the danger was gone. Huang Hongbin finally breathed a sigh of relief and sat back on the chair.

"Yao... Thank you this time." The unshaven director didn't care about the rules and took off his hat briefly in the duty room to cool his head down.

"Safety is more important than Mount Tai." Zhang Yifu looked at the extinguished furnace and wanted to get in and see what it was like. Of course, it was just thinking about it. His body might have been smoked into carbon-based compounds just as soon as he approached the vent.

At this moment, Fu Bo came out of nowhere and walked into the duty room and said, "Oh! The shutdown has been completed! Something happened in the coal warehouse just now, so I went to deal with it."

Zhang Yifu and Huang Hongbin looked at each other, and they couldn't laugh or cry, and they couldn't say anything.

Soon, Wang Zhenhua also came to this duty room and expressed deep confusion about what was happening in front of him: "Director Huang, what is the situation, temporary maintenance?"

"It might have been a failure and shut down, but it was fought for by Yifu to make an inspection." Huang Hongbin smiled bitterly.

"Oh, that's OK! Don't make a malfunction!" There are many problems with the subsequent maintenance, so naturally Wang Zhenhua is going to take action. He thought that the annual inspection would have to wait for another ten days and half a month. This time, a new situation suddenly appeared, and he had to mobilize his troops immediately. "Yifu, it seems that the maintenance is about to start tonight?"

"Well, not only maintenance, but also many places to be renovated, including the motor. When something happened suddenly, we can only plan ahead and have a temporary meeting in the afternoon." Zhang Yifu said embarrassedly, "Old Wang, thank you again."

"Hi, I'll get it sooner or later. Have you notified other workshops?" Wang Zhenhua's mentality has already been corrected, and he doesn't feel that he is suffering at this time. "In the standard-to-compliance plan, many renovations require other workshops, and the work team cooperates with him."

"Well, I will talk about it in the afternoon." Zhang Yifu looked at the boiler and said, "Now we have to figure out whether it is scorched."

"Yes, make sure the scorch is clear." Huang Hongbin now has extremely hope that scorch is scorched, so that everything will be explained. If you can't find the scorch in the remaining coal slag in the furnace, it will become an unknown problem and will be endless!

Each boiler has a special slag discharge pipeline. The burned cinder will be sent to a unified slag discharge yard through the pipeline. As a few people said, they would leave the factory and walk towards the slag discharge yard to see what the coal in Zhaoxian burned.

At this moment, the squad leader ran over again: "Director, it seems that the slag has not been discharged, the slag has been produced too little, and the temperature in the furnace drops very slowly."

"What? Is it blocked?" Huang Hongbin was shocked. At this time, he was not worried or nervous, but happy.

"Ah... it's blocked..." The squad leader could not understand why the director was so excited and happy.

"Cooling! It's about scorching!" Huang Hongbin slapped his palms and sat back on the chair. "The volume of scorching may not be large and did not cause fire extinguishing, but it was enough to block the slag discharge outlet! Fortunately, it was found in time, otherwise it would be congested after a long period of blockage and the cinder slag was congested, and the lightest failure was to extinguish the fire, which was a little more serious... the consequences were unimaginable!"

Huang Hongbin was excited to confirm the problem, but it was a damn scum, but soon, he was afraid that he would be on the back again. This time, it was really lucky. Fortunately, it was shut down in time and decisively. If he dragged it for another two hours, it would not be a normal shutdown. It was likely that it was a direct fault and tripped...

Just as something happened in Fengzhou, an accident occurred in northern Jilin?

Meet the standards? Haha.

Thinking about brewing for many years, the last wave of charges that had just begun to meet the standards were almost ruined by the boiler, Huang Hongbin was sweating again.

Zhang Yifu himself was not much better, and he was sweating coldly.

Originally, the coal-changing slag, scorching, tripping, and other things had nothing to do with him, but he caught up with the coal mixing test he arranged. Fortunately, nothing happened now, so he could check and analyze it carefully. If the shutdown was directly blown up or down, he would have arranged to start Zhaoxian coal in advance for the test. Then there would be no one to argue!

But now on the contrary, he and Huang Hongbin were keen enough to extinguish him when the danger first arose. He was foresighted and eliminated hidden dangers before officially launching Zhaoxian coal!

One in the sky and the other underground.

Thank you, Dad, for your repeated encouragement, we have become a man as stable as Mount Tai!

…………

Since the boiler was basically extinguished at this time, it was impossible to detect the situation in the furnace. At least 6 hours of cooling naturally, everyone was not in a hurry after a false alarm and naturally concentrated in the conference room. Since the maintenance incident happened suddenly, many work had to be discussed in advance.

In fact, most of the equipment and main pipelines of the power plant are incomprehensible during operation, let alone the transformation, and only in this kind of major inspection once a year can there be a chance to take action.

Fortunately, the working group of the Standards Office has been preparing for the future. It made a renovation plan during the maintenance period two weeks ago and could start construction at any time, otherwise it would really waste a lot of valuable time.
