Honeycomb briquet,biomass briquettes and bituminous coal from suburb of Beijing were chosen as testing samples to carry out combustion experiments. The characteristics of inorganic pollutant emission factors and VOCs emission factors released from the flue gas were studied. The results showed that under the condition of sufficient combustion, the average emission factors of SO from these three types of coal respectively were 1.50,1.91,1.62 kg·t;NO 0.420,0.901,2.20 kg·t;CO 22.4,37.3,87.3 kg·t. Combustion emission factors of gaseous pollutants for NO and CO were in the order of bituminous coal > biomass briquettes > honeycomb briquet. SO emission factors were in the order of biomass briquettes > bituminous coal > honeycomb briquet. The 2014 emissions inventory of the three civil coal combustion pollutants in Beijing was obtained. Bituminous coal emissions of SO was more than 5.5×10 tons,NO was more than 7.5×10 tons,CO was more than 290×10 tons. All these coal types released more kinds and higher concentrations of volatile organic compounds in ignition phase and damp down stage. VOCs emission factor was the highest during ignition phase, followed by damp down phase.
选取北京郊区的蜂窝煤、生物质型煤和烟煤作为测试样品进行燃烧实验。研究了烟气中无机污染物排放因子和挥发性有机物(VOCs)排放因子的特征。结果表明,在充分燃烧条件下,这三种煤的SO平均排放因子分别为1.50、1.91、1.62 kg·t;NO为0.420、0.901、2.20 kg·t;CO为22.4、37.3、87.3 kg·t。气态污染物NO和CO的燃烧排放因子顺序为烟煤>生物质型煤>蜂窝煤。SO排放因子顺序为生物质型煤>烟煤>蜂窝煤。得到了2014年北京市三种民用煤燃烧污染物的排放清单。烟煤的SO排放量超过5.5×10吨,NO超过7.5×10吨,CO超过290×10吨。所有这些煤种在点火阶段和熄火阶段释放的挥发性有机化合物种类更多、浓度更高。VOCs排放因子在点火阶段最高,其次是熄火阶段。
