淮南电厂粉煤灰的物质组成特征及其评价

Physiochemical Characteristics and Utilization of Coal Ash in Huainan Power Plant

利用XRF、XRD和ICP-MS等方法,对淮南电厂采集的20个粉煤灰样品的化学成分、矿物成分和微量元素的含量进行测试分析,并在分析的基础上,对淮南电厂粉煤灰中有害元素进行环境影响评价,并结合当前粉煤灰的利用情况,提出了合理的资源化利用途径。

In order to analyze the chemical composition of Huainan coal ash, 20 coal ashes were collected from Huainan Plants. The concentrations of trace elements in the collected samples were determined by ICP-OES and ICP-MS. The chemical compositions of the samples were determined by XRF. Based on these chemical compositions, mineral composition and trace elements content, to evaluate the harmful elements which influence on the environment, and combining with the current ash resource-oriented utili- zation, the reasonable channels to take advantage of coal wastes effectively were also presented in the current study.
