摘要
燃煤烟气中NO和SO2的氧化对于提高其脱除效率和改良脱除产物有重要意义。基于大气化学的研究成果,本文提出了利用链式反应同步氧化烟气中NO和SO2的设想。阐述了该方法的反应机理,数值实验研究了在烟气条件下该链式反应发生的可能性以及反应温度对NO和SO2氧化率的影响,提出了利用低成本的添加剂引发链式反应的方法,并分析了选择添加剂的原则。
Oxidation of NO and SO2 in flue gas emitted from coal combustion has great importance on improving their removal rate and on modifying byproducts. Based on atmospheric chemistry research, a method was presented to simultaneously oxidize NO and SO2 in flue gas by chain reactions. Reaction mechanism of this method was described. Numerical simulation was developed to investigate the possibility of chain reactions' occurrence and reaction temperature's influence. Techniques to initiate chain reactions were discussed and low cost additive method was recommended. Principles for additive selection were given.
