燃煤电厂烟气中汞控制技术研究

介绍了溶解法、吸附法、化学法和鳌合法等4种燃煤电厂烟气脱汞技术。从机理上分析了烟气脱汞技术的工艺过程,对脱汞技术的进一步开发和工业化进程具有促进作用。     

粉煤灰中氨氮的测定方法研究

从浸提、干扰去除和显色3个方面对纳氏试剂分光光度法进行优化改进,建立了一种用于粉煤灰中氨氮测定的适宜方法,并利用浸提完全度和精密度实验对该方法了进行了评价。优化后的方法为:按固液比1∶10加入0.05 mol/L H_2SO_4振荡浸提30 min,再加入1.5 mL酒石酸钾钠溶液(500 g/L)和1.5 mL NaOH溶液(5 mol/L)去除金属离子干扰,最后加入1.5 mL纳氏试剂进行显色。粉煤灰浸提后残渣的蒸馏液中未检测出氨氮,说明浸提效果较为完全。同一样品的8次平行测定结果的相对标准偏差为6.10%,说明该方法稳定可靠。     

便携式烟气分析系统在燃煤电厂CEMS比对监测中的应用
