| 中文摘要: |
| 通过对SNCR技术中NOx还原的影响因素分析，选取合适的喷射点位置将喷枪分层布置，不同喷射单元喷射流量的动态分配及多支独特的PQ-O2喷枪的组合使用，实现SNCR技术中的还原剂分布场和NOx的浓度分布场一致，结合独有的“PID+趋势”控制方法可将窑尾系统的NOx排放浓度控制在100 mg/m3以下。 |
| 英文摘要: |
| Locate spray guns in layers at suitable spots determined through analyzing the factors affecting the reduction of NOx in SNCR technology. Realize the distribution of reductant in SNCR technology in accord with the distribution of the concentration of NOx through constantly adjusting the spraying flow of various spraying units as well as simultaneously using several unique PQ-O2 spray guns. With the combination of the unique “PID + tendency”control method, the emission concentration of NOx can be kept below 100 mg/m3 in the kiln inlet system. |
