In the depths of winter, it is the most difficult time in Yanjing and the north.

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

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

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

For a quarter of an hour, he wished that he had transplanted the green filament, because the transplanted green filament would not have to breathe such foul air, and the various small particles of pollutants in the air would not have to enter the lungs.

For a while, Mo Li, who worked in Hai Province, was very unaccustomed to the air of Yanjing.

Because of its long coastline and tropical monsoon climate, the air quality on the island is very good, as the air quality on the island is very good.

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

The members of the organizing committee saw that Zhou Xiao and his party had very uncomfortable expressions, and they also knew that they felt uncomfortable because of the air in Yanjing.

The director hurriedly said: "Mr. Zhou, Mr. Wang, I'm really sorry, in the winter, the north will be warmed, and coal will be burned as soon as it is heated, although we Yanjing has completed the conversion from coal to gas, but many cities in the north still have to rely on coal burning for heating, this coal burning, the pollution is heavy, and the air will not care which city you can get into, which city can not go in, and none of the entire northern cities can be spared." ”

The joke of the director of the department amused everyone, and Zhou Xiao didn't want the director of the department to be too embarrassed and said: "In fact, in winter, the weather conditions are similar all over the country, and there is no way, you have to burn coal in winter." ”

The air quality in Yanjing is the worst in winter, on the one hand, because Yanjing's population, car ownership and the large number of polluting enterprises in the surrounding cities lead to large emissions of polluting gases.

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

The north adopts the central heating model, and most of them are also coal-fired heating, which is of course seriously polluted.

Why not use new energy?

It's not that you don't use it, it's that you can't use it,

Xia is a country with relatively scarce per capita energy, especially oil and natural gas, and relies heavily on imports.

Many years ago, the northern cities of Xia Kingdom mentioned switching from coal to gas, which means that natural gas heating boilers are used to generate heat to facilitate the heating of the people, rather than using coal to heat boilers.

The reason for 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's requirements for the environment, especially air quality, have become higher and higher, and the quality of coal has become higher and higher in the north.

Cheap and cheap domestic coal cannot meet the emission requirements of most boiler plants, which is why coal is required to switch to gas.

The policy of switching from coal to gas has been publicized and promoted for several years, but the effect is not good.

There are three main reasons.

One is that the price of natural gas is much higher than that of coal, and the government can subsidize some of it, but most of it is still borne by the people, and the winter in the north is very long, from the end of September of the first year to March of the second year, and the resulting gas costs are 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, so it welcomes the conversion from coal to gas.

But what about other northern cities outside of Yanjing?

There are many small and medium-sized cities in the north, and the residents of these cities have average incomes, and the living pressure is very high, and the income is far less than that of Yanjing citizens.

Heating costs are related to the livelihood and quality of life of ordinary people, and a little increase in price will cause dissatisfaction among the people.

After the coal to gas, the annual heating bill will increase significantly, and most people are not willing to accept it.

As a result, a few years after the policy was promoted, residents of many second- and third-tier cities, with the exception of Yanjing and other first-tier cities in the north, did not implement it.

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

The amount of natural gas imported is limited, and there is a shortage of gas supply in the winter when the amount of gas used increases sharply.

In the winter in the north, it is more than 10 or 20 degrees below zero, and the citizens do not want to stop heating all of a sudden.

The third reason is that many cities in the north have been heating for decades, and coal-fired boilers for central heating are very common and the technology is very mature.

If you want to change a coal-fired boiler to a gas-fired boiler, this is a very large amount of work and very costly.

Tier-1 cities such as Yanjing can afford such renovations, but many third- and fourth-tier cities have low GDP and tight government finances, making it very difficult for them to switch from coal to gas.

Based on the above reasons, five or six years after the introduction of the coal-to-gas policy, and with people's higher and higher requirements for domestic air quality, the air quality in the north will drop sharply in winter.

In addition to the poor air quality caused by burning coal for heating, electricity consumption in the north also spikes in winter due to long lighting hours.

More than 90 percent 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, but also a surge in the use of coal, and it is no wonder that the air in the north is better in winter.

This problem has plagued northern cities for many years.

In addition to the arrangement of the organizing committee to show respect for Zhou Xiao, the most important thing is to introduce Zhou Xiao to Mr. Xu of the North Energy Group Company.

North Energy Group is one of the largest energy group companies in Xia.

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

For example, in winter, North 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 the social and economic environment, the citizens of the north, including Yanjing, have higher and higher requirements for air quality, but over the years, the environment in the northern winter has not changed.

There are more and more patients suffering from lung cancer in Yanjing, and 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 priority.

The ionization bacteria of the origin group have performed very well in Jiangcheng, and the person in charge of the North Energy Group hopes to have a face-to-face talk with Zhou Xiao to see if ionization bacteria can also be used in the north to generate electricity.

If 50 percent of the coal power in the north could be replaced with electricity, the air in Yanjing would not be as bad as it is in winter.

In the car, the director of the department euphemistically expressed this opinion to Zhou Xiao.

The director said: "At present, most of the electricity in Xia, especially in the north, is coal-fired power, and most of the boilers are also coal-burned. ”
