Air pollutant control and strategy in coal-fired power industry for promotion of China's emission reduction

摘要

Coal-fired power industry has always been the major power source in China.As coal-fired power industry consumes around a half of China's coal production,it is always thought to be a big air pollutant emission source.As more and more strict legislations in coal-fired power industry have been issued by the government,the emission performance in coal-fired power industry has been drastically reduced recently.Based on a brief review of the development of emission control in China's coal-fired power industry,the affecting mechanism among the development of installed capacities of emission control device,pollutant emission,and emission performances in coal-fired power industry is studied.According to a systematic study on the development of emissions of classified categories,the role of coal-fired power industry as a pollutant source is reevaluated.It is found that,coal-fired power industry has contributed the most to China's emission reduction,and the barycenter of air pollutant emission has been transformed to other high energy consumption industries,like heat,iron/steel,and cement.Then some development strategies are suggested,such as maintaining the current emission standard in coal-fired power industry;expending the coal-fired power emission standards to categories of heat generation and supply,nonmetallic mineral production and ferrous metals smelting and processing;and controlling other heavy metal by consulting the method of Hg control.
