| 摘 要： | 利用ICP-AES光谱仪和TOC总碳分析仪对不同粒级下的飞灰颗粒进行了元素测定,对元素分布规律的形成原因进行了分析.分析结果表明:煤经旋流燃烧器燃烧而未经过除尘设备的飞灰中300目以下小颗粒含量较高.随着燃烧温度的升高,大颗粒的含碳量增加,小颗粒的含碳量减少,元素Al、Mg、Cr在各个粒级中含量变化不大,Ti、Ba、V在大于280目的小颗粒中含量有下降趋势,其他大部分痕量元素在大于300目的小颗粒中得到富集.

| Abstract: | Carbon and other thirteen metal elements in fly ash particles were divided into fourteen groups,and were analyzed with ICP-AES spectrometer and TOC analyzer.The investigation indicated that the quantity of particles(under 300 mesh) is the highest in the fly ash which came from whirl burner without dusting.The content of carbon in big-particles increased with increasing of temperature,reversing the small-particles.The content of Al,Mg and Cr maintained stable content in different sizes.Ti,Ba and V had the tr... |
