摘　　要：2017年11月—2018年3月是沈阳市冬季采暖期,这5个月污染天数为38 d,平均每月为7.6 d,2017年4月—10月非采暖期的污染天数为31 d,平均每月只有4.4 d,可见冬季供暖燃煤燃烧排放是造成沈阳市大气污染的主要原因。通过对10个较大供暖单位的28个热源厂,84台锅炉,44个排放出口的TSP,SO2,NOX的采集,分析采暖期沈阳市燃煤燃烧排放的特点及其对空气质量的影响,并提出了改进意见,对改善沈阳市冬季空气质量有着借鉴的意义。Nov. 2017-Mar. 2018 is the winter heating period in Shenyang. The number of polluted days in the 5 months is 38 days, the average month is 7.6 days, and the number of non heating days in Apr. 2017 to Oct. 2017 is 31 days, and the average month is only 4.4 days. It can be seen that heating coal burning emission in winter is the main cause of air pollution in Shenyang. Through collecting 28 heat source plants of 10 large heating units, 84 boilers and 44 emission exits TSP, S02 and NOx, this paper clarifies the characteristics of coal burning emission in Shenyang and the influence on air quality during the heating period, and puts forward some suggestions for improvement, which is of reference meaning to improving the air quality in winter in Shenyang.
