摘要
通过观察众多电厂脱硫系统性能检测的数据发现,烟气经过石灰石-石膏脱硫系统后氮氧化物的浓度及其组成成分发生了如下变化:NO浓度下降,NO2浓度升高,NOX的浓度下降;NO的比例比脱硫前降低3%左右,同时NO2的比例升高。通过分析得出:产生这些变化的原因主要是由于NOX与脱硫浆液中的某些成分发生了化学反应以及NO的自身氧化等。
Through the observation of many power plant desulfurization system performance test data, we found that the concentration of nitrogen oxides and its composition has changed after limestone - gypsum flue gas desulfurization system. These changes mainly reflected in ： NO concentration dropped, NO2 concentration increased and the concentration of NOx declined ; NO reduced the ratio of around 3 percent, while the proportion of NO2 increasing. The reason for these changes is that NOx reacts With desulfurization serous and the oxidation of NO.
