摘要
氮氧化物是燃煤电站锅炉排放的大气污染物之一。在410 t/h锅炉上进行了NOx排放特性试验,试验得出锅炉过量空气系数、燃烬风比例、制粉系统投运方式、再燃燃料比例对锅炉效率和NOx排放的影响,为锅炉优化运行,降低NOx污染物排放提供参考依据。
One of the primary factors of atmosphere pollutants is NOx from coalplants. In this paper, the characteristics of NOx emission and control for 410 t/ boiler were reported. Excessive air, OFA damper percentage, state of pulverized ration systems operation, reburning coal percentage on NOx emission and comb red power coal-fired coal prepa- ustion efficiency have been investigated. The results show that NOx emission will increase with O2 in flue gas increases. The O2 in flue gas an optimum value of 2.7 %-3.2% for lower NOx release during coal combustion.
