摘要(Abstract)：

为比较新疆地区典型高碱煤和高氯煤在燃烧条件下颗粒物生成特性，采用三段式高温沉降炉系统开展在空气气氛下燃烧准东煤和沙尔湖煤的实验，分析燃烧后颗粒物特征。采用Dekati低压撞击器（Dekati low pressure impactor+,DLPI+）进行了颗粒物的分级收集，对其质量粒径分布、元素分布特性以及颗粒物微观形貌进行了讨论分析。结果表明：2种煤样燃烧生成的颗粒物均呈现双模态分布，沙尔湖煤的细颗粒物产率明显高于准东煤；细模态颗粒物的主要成分是Na和Cl，准东煤与沙尔湖煤产生的PM_(10)中的Cl占原煤中Cl质量的11.8%和28.9%,Na占煤灰中Na质量的2.66%和7.53%；高含量的碱金属和Cl会促进细颗粒物生成，沙尔湖原煤中的Cl大量迁徙进入颗粒物中，对细模态颗粒的生成贡献较大。
