| 摘 要： | 在小型实验台上研究了NO对汞形态的影响。结果表明:在不含HC1气体的模拟烟气中,加入NO后转化率明显增加;较高浓度的NO会引起汞转化率下降但仍高于无NO的体系;随反应温度的升高汞的转化率逐渐降低;SO2的存在引起汞转化率升高。在含HC1的模拟烟气中,随反应温度的升高汞的转化率升高;SO2的存在引起汞转化率下降;NO的存在会提高汞的转化率。在一般烟气体系中, HC1可以促进汞的氧化;较高的O2浓度也可以促进汞的氧化。

| Abstract: | A bench-scale experimental is conducted to study effects of NO on the speciation distribution of mercury in coal-fired flue gases. The test method used here for mercury speciation was Ontario Hydro Method. The speciation distribution of mercury in different coal-fired flue gas systems was studied in typical constituent flue gas systems. The conclusions are as follows: In the coal-fired flue gas systems without HC1, the conversion ratio of Hg2 to total Hg will become lower with reaction temperature becoming higher; O2, NO and SO2 can slightly praise the conversion ratio of Hg2 to total Hg. In the coal-fired flue gas systems containing HC1, the conversion ratio of Hg2 to total Hg will become higher at elevated temperature; SO2 can decrease the conversion ratio of Hg2 to total Hg; HC1, NO, O2 can enhance oxidation of Hg vapor. |
