| 摘 要： | 介绍了煤燃烧过程中NOx生成机理和电站锅炉采用低NOx燃烧技术.通过对某电厂670 t/h锅炉进行炉膛出口氧量、一次风速、二次风配风方式、燃烧器上、下组的给粉方式、一次风煤粉浓淡比等对NOx排放量、飞灰可燃物含量和锅炉再热蒸汽温度的影响规律的试验研究.得出水平浓淡风煤粉燃烧技术能降低NOx排放量,确定了给出锅炉优化运行方式.试验结果表明燃烧优化调整是提高锅炉运行的经济性和降低NOx排放量的有效方法. |
| 关 键 词： | NOx 低NOx燃烧技术 燃烧优化 |

| Abstract: | The mechanism of NO_(x) formation during coal combustion and Low-NO_(x) combustion technology adopted by utility boiler are introduced.The experimental research on a 670 t/h boiler is carried out in view of the influences of furnace outlet oxygen,primary air velocity,secondary air distribution,coal feeding for burner groups,primary air/coal ratio etc.on NO_(x) emission,combustibles in fly ash and reheated steam temperature,it can be known that horizontal bias coal/air combustion technology can reduce NO_(x) emission remarkably,and optimal operation mode of boiler is determined.The results show that combustion optimization is an effective way to improve economy of boiler operation and reduce NO_(x) emission. |
| Keywords: | NO_(x) low-NO_(x) combustion technology combustion optimization |
