摘要
综述在循环流化床(CFB)燃烧条件下关于NOX生成和分解机理的理论和实验研究结果。实验确定在CFB燃烧温度区域NO在KRUPP焦碳表面进行还原反应的反应动力系数,同时针对CO促进NO在焦碳表面的还原反应进行专项实验,结合实验结果分析CO参与NO与焦碳的反应机理。
This paper describes the mechanism of NOx formation and destruction with laboratory studies. The main aim of the experiment is to determine kinetic expressions describing NO reduction on KRUPP char under conditions relevant to combustion applications. An experimental study of heterogeneous KRUPP char combustion and NO reduction reaction over char has been conducted, the NO-KRUPP char reduction reaction rate constant β can be calculated . Experiments also investigate the enhancement of NO reduction by char in presence of CO, the results are well agree with the relevant mechanisms.
