摘要
本文以三种典型煤为对象,测定了煤及灰中汞,砷,硒的浓度,了解了元素的挥发性.对钱家营褐煤进行了不同温度的燃烧实验.测定了在不同温度下燃烧灰中汞,砷,硒的含量变化.将所得实验结果与化学热力平衡分析工具F*A*C*T2.1模拟系统结果相比较.推测了其中可能发生的反应.
The concentration of mercury, arsenic and selenium in three typical coals and high temperature ash were determined. The behaviour of three elements during coal combustion were also investigated in different temperature. We also compare the result with that of chemical thermodynamic equilibrium calculation. According to above experiment data we suggest some potential mechanism involved.
