Jiang Yaodong said that this argument comes from the support of data. “In 2013, 380 million tons of coal were burned in the Beijing-Tianjin-Hebei region, 20% of which was loose-burned coal. However, the amount of sulfur dioxide emitted after combustion is basically the same as that of all large power plants. Beijing Winter Unit The concentration of carcinogens in PM2.5 is 25 times that of summer. What is the reason? In fact, it is mainly due to the influence of loose coal." Jiang Yaodong said. It is undoubtedly an important means to solve this contradiction by changing the bulk burning coal to concentrated combustion and increasing the proportion of coal power generation. In particular, it is necessary to vigorously develop large-capacity, high-parameter coal-fired thermal power units. According to Jiang Yaodong, the coal consumption of coal-fired power plants varies greatly. The coal consumption per kWh of a million kilowatt ultra-supercritical unit can be less than 300 grams, while some small thermal power units have to reach more than 400 grams. The pollution treatment capacity of large units is also better than that of small units, and even near zero emissions can be achieved. However, the problem now is: "Although the various aspects of these measures have already formed a consensus, the state has formulated relevant policies, but due to institutional reasons, the implementation is not smooth." Jiang Yaodong believes that "it is obvious that the unreasonable system is the extensive economy." Important reasons for development and extensive use of coal energy. In order to eliminate atmospheric haze, we must first solve the "institutional haze." In particular, he pointed out that despite the emergence of unconventional energy sources such as shale gas and combustible ice, coal is still the cheapest and safest source of energy. Based on the resource endowment, the status of coal as the main energy source in China will not change. The key now is how to clean and use coal efficiently. He suggested that at the national level, it is equally important to promote the clean and efficient use of coal and the development of clean energy. "As China's basic energy, coal must be revolutionary, but it is not "the life of the coal." It is not early to mention the "post-coal era", "de-coalization" is not desirable. The core of the revolution in the coal field is to promote the entire coal industry and the whole industry as a whole. Clean use of the chain." Jiang Yaodong pointed out.

Extensive use of coal is the main cause of haze
Lift governance haze, "coal" seems to be the first to be considered first of all to "suppress" the object. However, Jiang Yaodong, a member of the National Committee of the Chinese People's Political Consultative Conference and vice president of China University of Mining and Technology (Beijing), is "quenching" for coal: "I want to be the name of coal." Practically speaking, it is not the smog caused by coal, but the extensive use of coal is the cause of fog. One of the main reasons for cockroaches."
