摘要: 对原煤、尾气和煤渣中多环芳烃进行了相关性测试。在模拟工业锅炉代表性燃烧条件下将烟煤和无烟煤样品在管式炉中燃烧,分别采用GCMS和HPLC法对原煤、尾气和煤渣中的多环芳烃种类和含量进行了定性和定量测定。通过在特定条件下某一煤种中多环芳烃种类、含量在燃前、燃后变化的相关性,探索煤中多环芳烃在燃烧过程中的衍变规律Abstract: The samples of bitumite and anthraeite were burned in the tubestove under the representative burning conditions used in the simulated industrial boiler. Identification and quantitative determination of PAHs in coals, burning tail gases and slags were carr
