摘　　要：面向燃煤烟气NOx控制领域,H_2O_2作为一种环境友好型处理工艺备受青睐。主要考察了喷入方式、氧化剂浓度、烟气参数等关键因素对NO氧化度的影响。研究发现,当顺流喷入、烟气量为6740 m3/h、氧化剂浓度为50%、喷射角度为120°时,NO氧化度最佳。与浓度为10%尿素溶液匹配时,NOx脱除效率可达到38.86%。The process of flue gas purification with H2O2 for nitrogen oxide abatement has become a resource - economical and environment- friendly technology. Influent factors, such as the way of spray, Oxidant concen- tration, flue gas parameters and so on, were studied. It is found that oxidation of NO optimal conditions are downstream, gas flow of 6740 m^3/h, the oxidation agent concentration of 50%, the ejection angle of 120°. With the urea solution of 10% under optimal conditions, NOx removal efficiency can reach 38.86%.
