| 摘 要： | 在自行设计的一维煤粉燃烧试验台上,研究了烟气汞形态的分布特征,并分析了NaCl作为添加剂与煤混烧对汞形态分布的影响.结果表明:在试验煤种烟气中,气态汞是烟气汞最主要的排放形式,二价汞是气态汞的主要形式,飞灰中的汞含量比底渣中的汞舍量高;NaCl的添加使气态二价汞和单质汞占总汞的百分比都有不同程度的下降,而颗粒态汞的比例相应增加,但随着NaCl添加量的增加,颗粒态汞的增加量逐渐趋于平缓,单质汞的减少量也相应降低,趋势趋于平缓.

| Abstract: | Mercury speciation distribution features in flue gas were studied on an self-designed one-dimensional pulverized coal combustion test rig.And the influence of NaCl,being used as an additive into the coal combustion,on the mercury speciation distribution was analyzed.Results show that the gaseous state of mercury is of the overwhelming content in the emitted mercury for the test coal,and the bivalent mercury is of the major part in the gaseous mercury.In addition,the mercury content in fly ash is higher than... |
