| 摘 要： | 通过实验室试验和实际选煤厂收集的数据 ,研究了洗选处理对燃煤中大气有害物质 (HAPM )分布赋存特征的影响作用。测试数据表明HAPM倾向在煤样无机矿物质中富集。从实际选煤厂采集的数据也表明 :选矿工艺流程可显著降低煤中HAPM的丰度。降低煤样粒度上限可使无机矿物质解离更充分 ,结合相应先进分选工艺可使HAPM脱除率显著提高 ,成本低、技术成熟的洗选工艺可行之有效地脱除燃煤中HAPM物质。

| Abstract: | Influences of coal preparation on hazardous air pollution materials (HAPM) in terms of their distribution and occurring mode were studied on the basis of data from experiments and on-site coal preparation plants. The study showed that current coal preparation technologies could significantly reduce HAPM concentrations in coal, and hazardous trace elements removal could be improved by decreasing upper limit of the feeding granularity. |

| Keywords: | coal preparation HAMP distribution and occurring mode rate of removal |
