Abstract: In order to support the in-depth control of fugitive particulate matter emissions in the coal yard of coal-fired power plants in Beijing-Tianjin-Hebei and surrounding areas, by taking the data collected from the year of 2017 as the baseline and the total suspended particulate (TSP) as the research objective, the temporal and spatial variation characteristics of fugitive particulate matter emissions from the coal yard of coal-fired power plants are explored. Based on relevant policies, two scenarios with different approaches are designed and their control effects are analyzed respectively, i.e., porous fences reconstruction and fully enclosed reconstruction. The results show that in 2017, there were 3 044.41 tons of fugitive particulate matter emitted from the coal yards in the above areas. Winter and spring seasons (from January to May) are the critical time period for the control of fugitive particulate matter emissions. With the approach of total enclosure reconstruction, the fugitive particulate matter emissions can be reduced by 98.33% from coal yards. From the perspective of improving the local environmental quality, emission control of the fugitive particulate matter in coal yards is more cost-effective than that of “colored plume” reduction. At last, it is suggested to attach significance to the control of fugitive particulate matter emission in the coal yard of regional coal-fired power plants. Also by seizing the critical period of environmental management, the fully enclosed reconstruction of coal yard should be carried out in an orderly and step-by-step manner.
