在热态燃煤试验炉上，利用OHM法、氢化物发生-电感耦合等离子体原子发射光谱（ HG-ICP-AES）法，研究了原煤燃烧气态单质Hg（ Hg0）、气态二价Hg（ Hg2＋）及颗粒态Hg（ Hgp ）分布特性，废水中Cl与Na浓度、烟气中SO2与NO对Hg0的氧化影响。结果表明，试验燃煤F、Cl浓度低，1＃和2＃燃煤烟气中Hg0占输入总Hg（ HgT ）比例分别为68.3％和80.6％，而Hg2＋比例仅占22.2％和13.1％；在烟气中喷射丙烯酸钠和萘磺酸钠废水的液气比为0.028 L/m3时，1＃和2＃燃煤烟气Hg2＋所占比例分别达到80％和75％以上，而HgP 的比例变化不显著；当喷射废水液气比为0.028 L/m3时，1＃和2＃燃煤烟气的SO2浓度下降11.4％～15.7％和12.2％～17.7％，促进了Cl对Hg0的氧化；而NO对Hg0的氧化不显著。

The Hg0 , Hg2+and Hg p distribution of coal-fired flue gas was investigated by the OHM and hydride generation-inductively coupled plasma atomic emission spectrometry ( HG-ICP-AES ) method.The impacts of chlorine and sodium content of wastewater and SO 2 and NO concentration of flue gas on Hg 0 oxidation were tested on the coal-fired test furnace in hot state .The results showed that the ferrous and chlorine content in the test coal was low and the ratio of Hg0 to HgT was 68.3%and 80.6%for coal-fired flue gas 1# and 2# respectively, while Hg2+ratio was only 22 .2% and 13 .1% respectively .When the sodium acrylate and naphthalene sulfonate wastewater liquid to flue gas ratio was 0.028 L/m3 , the Hg2+ratio reached higher than 80%and 75%in coal-fired flue gas 1#and 2# respectively .While , there were no significance variations for Hg p ratio in flue gas .When the wastewater liquid to flue gas ratio was 0.028 L/m3 , the SO2 concentration decreased by 11.4%-15.7% and 12.2%-17.7%for coal-fired flue gas 1#and 2#respectively , which accelerated Hg 0 oxidation .There was no significant effect of NO in flue gas on Hg0 oxidation.
