| 摘 要： | 对某电厂670 t/h锅炉采用一次风出口燃料分级、下部主燃区空气径向分级和炉膛轴向空气分级技术改造后,通过进行炉膛出口氧量、二次风配风方式、SOFA燃尽风量等对NOx排放浓度的影响规律的优化试验研究,可以大幅度降低NOx排放量。NOx排放浓度由525.3 mg/m3降低到287 mg/m3,脱硝效率达40%以上。 |

| Abstract: | After 670 t/h boiler adopting the technologies of primary air outlet fuel grading,the primary zone in the low part air radial grading and hearth axial air grading,the optimal experimental research is carried out in view of the influences of hearth outlet oxygen,secondary air distribution,SOFA air burn etc.on NOx emission,it can reduce NOx emission remarkably.NOx emission is reduced to 287 mg/m3 from 525.3 mg/m3,the de-NOx ratio is about 40%. |
