At ten o'clock in the morning, the launching ceremony of the No. 3 machine began. It is said that it is starting, in fact, it has already started, the thermal power unit starts from the complete cooling state, from the boiler ignition to the grid connection of the unit, it takes at least dozens of hours, it is impossible for so many people to spend a few days sitting here, so the No. 3 unit in northern Hebei has entered the start-up stage as early as three days ago, ignition, heating pipes, gas engine operation, grid connection has been completed, and what is to be performed in front of you is actually to raise the power to 100% rated value and fully burn this process.

In terms of environmental protection, it is also the data that the unit is running at full capacity to maximize pollution.

Under the order of the leaders of the power plant, all aspects of preparation were completed, and the unit began to increase its power.

This process is more obvious in the duty room, where the parameters continue to rise, but outside, people can only feel a slight increase in noise and a gradual increase in smoke exhaust.

Normally, there are two kinds of "chimneys" in the power plant that are smoking, one is a very tall smoke exhaust chimney with a height of more than 100 meters, where pollutants must be discharged to the air. There's also something that is hyperbolic in comparison, a volcano-like thing that is actually a cooling tower, and the water vapor emitted from the cooling tower looks much larger than a tall chimney, but it's completely harmless.

The presence of professionals are all professionals, the focus is naturally on the high chimney, after the dust removal and desulfurization transformation of the unit, a separate desulfurization tower has been added next to the chimney, the flue gas from the boiler needs to go through a complete set of desulfurization facilities before entering the chimney, at this time the desulfurization tower is also running at full speed, play its role.

At this time, at the top of the chimney, the smoke is thickening, indicating a lot of things.

Smoke can actually indicate many things visually, first of all, the color and the degree of turbidity. There is also a standard for this, a metric called "Ringelmann blackness" is used to measure this, mainly for soot, which will have a certain color performance at different concentrations, and in the era when environmental protection is not considered at all, the "thick black smoke" emitted from the chimney of the power plant. Not alarmist.

Slightly better than that, there is a certain degree of gray smoke, which is almost not allowed in Beijing-Tianjin-Hebei, but in the distance, small power plants are mixed, and this is occasionally the case.

In addition, the situation of green smoke and yellow smoke is mostly caused by the excess of a certain compound, which is not common, and is related to the type of coal and the combustion mode of the boiler. If the smoke is this color for a long time, you can report it.

At this time, the smoke coming out of the chimney of Unit 3 is thick white, extremely thick, and if you turn your head and compare it with the white smoke of other units, you will find that it is much thicker.

The young administrative cadre of the Provincial Environmental Protection Bureau frowned slightly and muttered in a low voice: "Why did you do desulfurization, and the smoke is thicker?"

It would be too unprofessional to ask this question. However, Niu Xiaozhuang, the head of the power plant's engineering who accompanied him, explained: "We use wet desulfurization, and the smoke discharged carries a lot of water vapor. It looks thick, but it's actually all water. ”

"Oh...... In short, it still depends on the test results. ”

"Yes, your people have already arranged the sampling and analysis equipment. Niu Xiaozhuang smiled and looked up at the chimney, Zhang Yifu, you seem to have done another thing.

Due to the fact that it was well prepared before. The unit soon entered the stage of full load and stable operation, and everyone got up and visited the desulfurization tower facilities as planned, but the environmental protection cadres did not plan to visit it closely, just take a look at it from afar. Although the safety factor is absolutely up to par, standing next to this kind of thing is always scary. Lin Lizheng specially beckoned Zhang Yifu to come over to explain the structure and technical principles of the desulfurization tower to the people of the Provincial Environmental Protection Bureau.

"You say it can reach 400?" said the deputy director of the provincial bureau, the deputy director of the provincial bureau, who came to the largest environmental protection cadre this time, showed a look of disbelief.

"Yes, 400mg per cubic meter, if the coal type is good, it can be lower. Zhang Yifu is full of confidence.

"Isn't this far below our standard?" said to the people around him with a light smile, "Is this the best standard required, that is, 1200? I remember that the national average is ......."

A person next to him quickly replied: "The average in the province is about 3,000." ”

"Yes!" The deputy director didn't pay attention to Zhang Yifu at all, and smiled at Lin Lizheng, "Mr. Lin, I have seen the support of our power industry and Beimo Company for the new standard, but the number 400 he said is just a vision, right?"

Lin Lizheng was slightly embarrassed, this obviously didn't treat Zhang Yifu as a person.

Come to think of it, environmental protection cadres, there must be a lot of companies that lick their faces every day, and in his eyes, Zhang Yifu is probably one of them, this attitude is used to it, and it can't be changed, not to mention Zhang Yifu's wild words.

"I still have confidence in Hengdian and our Jibei plant. Lin Lizheng led out Zhang Yifu again, "Come on, Mr. Zhang can introduce the technology to Director Fu again, their core technology is independently developed, and some key components are used by Siemens, according to European standards......"

"Hi. Director Fu waved his hand and smiled, "In these years, everyone claims to have an imported technology, right? ”

The people around echoed, saying that Director Fu was right.

Lin Lizheng shook his head at Zhang Yifu in extreme embarrassment, he didn't want to do this.

Zhang Yifu didn't care, waved his hand and smiled, and took the initiative to move to the back of the team, it seems that this Director Fu is quite unkind to see him.

The desulfurization tower is just a distant visit, and after a while, everyone came to the duty room, not to visit the power plant, but to monitor the monitoring workstation equipped by Hengdian is here.

From the trend point of view, the CEMS flue gas monitoring system will play an increasingly important role in the future, requiring continuous monitoring, flue gas analysis data directly into the computer and network, and even directly with the environmental protection department network, real-time transmission of data, to achieve seamless monitoring.

Now naturally can not do this step, although the constant power equipment retains these interfaces, but the current final form of expression, is just a monitoring workstation in the duty room. Zhang Yifu simply didn't go on it, and let the people from the power plant demonstrate.

Niu Xiaozhuang should be responsible for this link, he has been familiar with the operation of this workstation, under the watchful eye of the company's leaders and environmental protection leaders, familiar operation, called up the real-time flue gas analysis data.

As soon as the picture came out, everyone was shocked.

In my impression, these things should be a bunch of strange English, but now they are facing a Chinese interface! This is too surreal.

Let's take a look at the three core indicators.

Soot concentration: 212

Sulfur dioxide: 378

Ammonia oxide (nitrate): 1059 (to be continued......
