摘要: 分析了胜利石油管理局胜利发电厂一期2台670t/h煤粉锅炉NOx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NOx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,NOx排放质量浓度下降幅度达到了40%,降低锅炉NOx的排放,取得了明显的效果。

Abstract: The reasons of higher NOx 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 NOx 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 NOx emission reached to 40%, the obviously effect in reducing boiler NOx emission was gained.
