| 摘 要： | 分析了胜利石油管理局胜利发电厂一期2台670t／h煤粉锅炉NOx排放质量浓度较高的原因，介绍了^#2炉通过分级配风和分级送粉的优化燃烧调整试验，使锅炉NOx排放质量浓度大幅降低的过程。在喷燃器改造为“水平浓淡风煤粉燃烧器”后，再进行分级配风和分级送粉优化燃烧，NOx排放质量浓度下降幅度达到了40％，降低锅炉NOx的排放，取得了明显的效果。

| Abstract: | The reasons of higher NOx concentration emission of two 670 t/h pulverized coal fired boilers in Shengli Power Generation Plant of Shengli Petroleum Administration of phase 1 were analyzed. The process of dramatic reducing NOx concentration by optimizing combustion was introduced. After jet burner changing to ＂horizontal bias air combustion pulverized coal burner＂ , and then staging air and staging powder transfer to optimize combustion, the decreasing amplitude of concentration NOx emission reached to 40% , the obviously effect in reducing boiler NOx emission was gained. |
