摘要: 采集了一台320 MW机组锅炉在三个过量空气系数下的飞灰样品，将采集的飞灰筛分为四个粒径，测定了各飞灰样品的含炭量；对各飞灰样品进行两种加热方式的热处理，利用LUMEX全自动测汞仪测定了处理前后各飞灰样品的汞含量。根据飞灰中汞随温度的释放规律确定了飞灰中汞的形态，对加热过程颗粒Hg释放动力学参数进行了计算。测试与分析结果表明，粒径小的灰颗粒中汞浓度较高；过量空气系数增加后，飞灰含碳量降低，但飞灰中汞随过量空气系数的变化随粒径的不同有所不同；飞灰中含汞化合物的主要形态为HgCl2和HgS，过量空气系数增加，飞灰中HgCl2比例减少，HgS比例增加，HgO与HgSO4的比例基本不变。停留时间是影响颗粒Hg生成的关键因素。过量空气系数越大，灰颗粒Hg释放的活化能就越大，大颗粒飞灰Hg释放活化能相对较大。
