2005年中国燃煤大气锑排放清单

采用基于燃料消耗的排放因子法,按照经济部门(电力、工业、生活消费及其他)、燃料类型(原煤、洗煤、焦炭、型煤)、燃烧方式(层燃炉、煤粉炉、流化床锅炉等)和除尘脱硫设施(机械式除尘器、湿式除尘器、电除尘器、袋式除尘器等)等将燃煤排放源进行分类,根据各省、市、自治区不同排放源类型的煤炭消耗量及平均锑含量,建立了2005年中国燃煤大气锑排放清单.结果表明,2005年中国燃煤导致的大气锑排放总量约为530.86t,排放量超过30t的省份依次为贵州(49.28t)、湖南(45.96t)、河北(37.36t)、山东(35.12t)、安徽(30.92t),表明中国燃煤大气锑排放主要集中在中东部地区.大部分排放来自工业和电力部门,分别占排放总量的47.2%和39.9%.

Atmospheric antimony emission inventories from coal combustion in China in 2005

The inventories of atmospheric antimony (Sb) emissions from coal combustion in China were compiled for the year 2005 utilizing the emission factor method based on provincial coal consumption and average Sb concentration in feed coal. Sb emission sources were categorized by economic sectors (power, industry, residential use, and others), fuel types (raw coal, washed coal, coke, and briquettes), combustion technologies (stoke, PC bolier, fluidized bolier) and pollution control equipments (cyclone, wet scrubber, ESP, fabric filter,etc.). The total atmospheric Sb emissions from coal burning were evaluated at 530.86t, in which Guizhou province had the heaviest emissions (49.28t), followed by Hunan (45.96t), Hebei (37.36t), Shandong (35.12t), and Anhui (30.92t), suggesting that the east and central China dominance of Sb emission. As for the sectoral contribution, approximately 47.2% of the total Sb emissions came from industry sector, and 39.9% from thermal power generation.
