| 摘 要： | 以2台600 MW超临界机组前后墙布置燃烧器的锅炉为研究对象,采用现场燃烧调整试验方法,进行了氧量、燃烧结构参数(包括一次风速、中心风量、二、三次风风量和二次风旋流强度等)、磨煤机运行组合方式、燃尽风量、煤质变化等运行条件对锅炉NOx排放特性影响的试验研究;采用统计分析方法对各种影响因素进行了定量分析和比较.结果表明:锅炉的运行氧量、磨煤机组合投运方式变化、燃尽风量是影响锅炉NOx排放浓度的主要因素,煤质的变化也不可忽视,经比较,燃烧器结构参数变化的影响较小;通过对主要因素的控制,可以显著降低锅炉NOx排放浓度,同时实现高锅炉效率. |

| Abstract: | Experimental study was carried out on two sets of 600MW supercritical boiler with burners arranged in front and back walls.By use of combustion tuning experimental method,the influence of boiler operational conditions on the characteristics of NO_x emission were studied,such as oxygen content,burner structural parameters(including primary air velocity,central air flow rate,secondary and tertiary air flow rate and swirling intensity of secondary air,etc.),combination modes of mills,over fired air(OFA) flow r... |
| Keywords: | supercritical boiler front and back wall fired burner low NO_x emission influence factors |
