摘　　要：本文研究了燃烧温度、燃烧气氛、煤粉细度和灰粒细度等因素与煤燃烧产生的细微粒子中部分重金属元素含量的关系,建立了灰粒中元素含量与备因素关系的模型,发现燃烧工况和灰粒细度与灰粒中元素的含量具有一定的相关关系.用模型对不同灰粒中的元素含量进行了预报,可用控制燃烧条件来减少重金属元素向大气的释放.In this paper, a regression model of relationship between four factors of combustion (temperature, atmosphere, sizes of coal power and ash particulates) and the contents of heavy metals in ash particulates released from coal combustion was indicated. The results showed that the circumstances of combustion and sizes of coal ash were correlated to the contents of heavy metals in ash. Furthermore,the model can be used to predict the contents of elements in different ash particulates. It can be applied to decrease the atmospheric pollution of the heavy metal by controlling the circumstances of combustion.
