【摘要】 研究了炉温、煤粉细度及燃烧中发生的化学反应对微量元素行为的影响．并用灰色关联法对影响微量元素在细微灰粒上富集的因素作了优势分析．同时建立了相对富集因子与灰粒粒径的函数关系，进一步定量描述了微量元素的富集行为．更多还原

【Abstract】 The effect of temperature and the size of pulverized coal and chemical reaction are researched.Moreover,a grey correlation method is used to analyze the key factors which affect the contents of trace elements in coal ash.The function relation between relative enrichment factor and the size of coal ash are established.So we can describe trace element enrichment behavior in fixed quantity.更多还原
