摘　　要：为深入了解陕西省民用散煤燃烧烟气中气态污染物(CO、NOx、SO_2)的排放因子,选取陕西省居民家庭使用频率较高的块煤及蜂窝煤,利用自行设计的采样系统对燃烧烟气中的CO、NOx、SO_2排放因子进行实测研究。结果表明,在充分燃烧条件下,烟煤、无烟煤、蜂窝煤气态污染物CO排放因子分别为:64.1、38.4、35.1g/kg;NOx排放因子分别为:1.49、1.21、0.50g/kg;SO_2排放因子分别为:3.48、1.35、1.23g/kg。NOx排放因子大小顺序为:烟煤>蜂窝煤>无烟煤,CO、SO_2排放因子大小顺序为:烟煤>无烟煤>蜂窝煤。获得了2016年陕西省民用散煤的气态污染物排放清单;块煤CO、NOx、SO_2的排放量分别为13.13、0.346、0.61万t,贡献率均超过了85%;农村生活领域散煤三种气态污染物的排放量占陕西省生活领域散煤排放总量近80%。因此,农村地区散煤的治理是陕西省改善空气质量、加强大气污染治理工作的关键。In order to better understand the emission factors of gaseous pollutants（CO,NOx,SO2）from residential combustion of raw coal in Shaanxi Province,lump coal and honeycomb briquet with higher household frequency in Shaanxi Province were selected to measure the emission factors of CO,NOx,SO2 using a self-designed sampling collection system.The results showed that under the condition of sufficient combustion,the emission factors of CO from bituminous coal,anthracite coal and honeycomb briquet were 64.1,38.4,35.1 g/kg;NOx 1.49,1.21,0.50 g/kg;SO23.48,1.35,1.23 g/kg.Combustion emission factors of gaseous pollutants for NOx were in the order of bituminous coal〉honeycomb briquet〉anthracite coal,CO and SO2 emission factors were in the order of bituminous coal 〉 anthracite coal 〉honeycomb briquet.The2016 emissions inventory of the gaseous pollutants from residential combustion of raw coal in Shaanxi Province was obtained.Lump coal emissions of CO was 13.13×10^4 tons;NOx was 0.346×10^4 tons;SO2 was 0.61×10^4 tons.accounting for more than 85% of the total.The emissions of gaseous pollutants from rural areas accounted for nearly 80% of the total emissions of Shaanxi Province.Therefore,the management of residential raw coal in rural areas is the key to improving air quality and strengthening air pollution control in Shaanxi Province.
