Chapter 404

Deep winter is the most difficult season in Yanjing and the north.

As soon as Zhou Xiao got off the plane, he saw a vast fog. The sky in the distance was gray and orange, and the air was choking.

Even wearing a mask, he felt that the air quality was very poor.

In recent years, Jiangcheng began to manage the environment with the assistance of the origin group, and the environment is getting better and better. From Jiangcheng with a very good environment to Yanjing with very poor air quality, Zhou Xiao felt that he was about to suffocate.

He even had a quarter of an hour to hope that he had transplanted chloromycetes, because the transplanted chloromycetes did not have to breathe such dirty air, and all kinds of small particle pollutants in the air did not have to enter the lungs.

For a time, Mo Li, who worked in Hainan Province, was not used to the air in Yanjing.

Hainan Province has a long coastline and a tropical monsoon climate, so the dirty air on the island can disperse quickly. In addition, there are very few industrial enterprises on the island, so the air quality is also very good.

Comparing the air quality between Yanjing and Hainan Province, Mo Li misses the days when he worked in Hainan Province.

The members of the organizing committee saw the expression of Zhou Xiao and his party very uncomfortable, and knew that they were uncomfortable because of the air in Yanjing.

The director of the Department hurriedly said: "Mr. Zhou, Mr. Wang, I'm really sorry. In winter, the North needs to warm up and burn coal. Although we have completed the transformation from coal to gas in Yanjing, many cities in the north still have to burn coal for heating. This coal burning has heavy pollution, and the air doesn't care which city you can go in and which city can't go in, None of the whole northern cities can be spared. "

The director's jokes amused the people. Zhou Xiao didn't want the director to be too embarrassed and said, "in fact, in winter, the weather conditions all over the country are similar. There's no way. In winter, we have to burn coal."

Yanjing's air quality is the worst in winter. On the one hand, Yanjing's population, car ownership and more polluting enterprises in surrounding cities lead to a large amount of polluting gas emissions.

The more important reason is that after winter, northern cities, including Yanjing, have high requirements for heating.

The central heating mode is adopted in the north, and most of them are coal-fired heating. Of course, the pollution is serious.

Why not use new energy?

No, it doesn't work,

Xia is a country with relatively poor energy per capita, especially oil and natural gas, which rely heavily on imports.

Many years ago, the northern cities of Xia State mentioned changing coal to gas, which means using natural gas to heat the boiler to generate heat, so as to facilitate people's heating, rather than using coal to heat the boiler.

The purpose of this is not that natural gas is cheaper, but because the pollution caused by burning coal for heating is very serious.

Xia is indeed a big coal producer, but most of the coal mines produced in Xia are not of high quality, and a large amount of PM2.5 and polluting gases will be released after combustion.

In recent years, as people have higher and higher requirements for the environment, especially for air quality, the quality of coal is also higher and higher when heating in the north.

Cheap domestic coal can not meet the emission requirements of most boiler plants, so it is required to change coal to gas.

The policy of coal to gas has been publicized and popularized for several years, but the effect is poor.

There are three main reasons.

One reason is that the price of natural gas is much higher than that of coal. The government can subsidize some, but most of it should be borne by the people. The winter in the north is very long. From the end of September of the first year to march of the second year, the resulting gas cost is very high.

Yanjing is the most economically and politically developed city in Xia, and the income of residents in the city is also very high. Therefore, it is welcome to change coal to gas.

But what about other northern cities outside Yanjing?

There are many small and medium-sized cities in the north. The residents of these cities have average income, great living pressure and far less income than the citizens of Yanjing.

Heating fee is related to ordinary people's livelihood and quality of life. A little price increase will cause people's dissatisfaction.

After changing coal to gas, the annual heating fee will increase significantly, which most people are unwilling to accept.

Therefore, after several years of promotion of the policy, except for Yanjing and other first tier cities in the north, many residents of second and third tier cities have not implemented it.

The second reason is that most of Xia's natural gas is imported from Russia.

The quantity of imported natural gas is limited. When the quantity of gas use increases sharply in winter, there will also be insufficient gas supply.

In winter in the north, it's often more than ten or twenty degrees below zero. Citizens don't want to stop heating all of a sudden.

The third reason is that many cities in the north have decades of heating history. Coal fired boilers for central heating are very common and the technology is very mature.

If we want to change the coal fired boiler to the natural gas fired boiler, the quantity is very large and the cost is very high.

Yanjing and other first tier cities can afford such transformation costs, but many third and fourth tier cities have low GDP and tight government finance, so it is very difficult for them to change coal to gas.

Based on the above reasons, five or six years after the introduction of the coal to gas policy, people have higher and higher requirements for living air quality, and the air quality will decline sharply in winter in the north.

In addition to the poor air quality caused by burning coal for heating, the power consumption in the north also surges in winter due to long lighting time and other reasons.

More than 90% of the electricity in northern cities comes from coal-fired power generation.

The surge in electricity consumption will lead to a surge in power generation and coal consumption. In this case, it is strange that the air in northern winter can be good.

This problem has plagued northern cities for many years.

The director of the Department came to meet Zhou Xiao in person this time. In addition to the arrangement of the organizing committee to show his respect for Zhou Xiao, the most important thing is to introduce Zhou Xiao and president Xu of North energy group (fictional) company.

Northern Energy Group Co., Ltd. is one of the largest energy group companies in Xia country.

The group is mainly engaged in the development and utilization of domestic energy and the import of foreign energy.

For example, in winter, northern Energy Group Co., Ltd. will mobilize coal resources from all over the country and even from overseas to supply heating enterprises in various cities in the north.

With the development of social and economic environment, northern citizens, including Yanjing, have higher and higher requirements for air environmental quality, but over the years, the northern winter environment has not changed.

More and more people in Yanjing are suffering from lung cancer. Lung cancer has become the disease with the highest mortality rate in Yanjing every year.

Changing the air quality in the North has become a top priority.

The ionizing bacteria of the origin group have performed well in Jiangcheng. The head of the northern energy group hopes to have a face-to-face interview with Zhou Xiao to see if ionizing bacteria can also be used to generate electricity in the north.

If 50% of the coal power in the North could be replaced by electric bacteria, the air in Yanjing in winter would not be so bad.

In the car, the director of the Department gently expressed this opinion to Zhou Xiao.

The director of the Department said: "at present, most of the electricity in Xia state, especially in the north, is coal power, and most of the boilers also burn coal. This time, Mr. Zhou can come to Yanjing, which is just able to point out the maze of energy and environmental protection issues in Yanjing."
