【摘要】 为了科学评估京津冀区域燃煤发电行业特别排放限值和超低排放相关要求实施后的大气污染物减排效果,以行业调查数据为基础,建立了2013年和2015年京津冀区域燃煤发电行业大气污染物排放清单,分析了装机容量与SO₂、NO_x和烟尘排放量的时空耦合关系,讨论了国家相关政策和标准的实施效果。结果显示:区域内2015年燃煤机组装机容量与2013年相比略有下降,SO₂、NO_x和烟尘排放量分别下降75.95%、83.09%和71.20%,减排效果明显。2015年100 MW以下等级机组3种污染物排放总量位居各机组首位,建议通过多种合理方式压减小型燃煤发电机组数量和排放浓度。更多还原

【Abstract】 From 2013 to 2015,multiple policies and emission standards were implemented for coal-fired power generation industry in Beijing-Tianjin-Hebei Region in China to reduce the total air pollution emission. In order to evaluate the implementation effects of the policies and emission standards,a survey based emission inventory was established. Spatialtemporal relationships between installed capacity of coal-fired power generators and emissions of SO₂,NO_x ,and dust were analyzed. Results showed that,from 2013 to 2015,although total installed capacity decreased slightly,total emissions of SO₂、NO_x and dust dropped 75. 95%,83. 09% and 71. 20%. The remarkable decrease of total emissions indicated a great implementation effects. The generators with less than 100 MW installed capacity discharged the most pollutions. The suggestion was to reduce the installed capacity and emission concentration of generators with less than 100 MW.更多还原
