摘　　要：某300MW燃煤锅炉低NOx燃烧改造后,对其进行燃烧优化调整试验。通过研究炉膛氧量、OFA风门开度和磨煤机组合方式对省煤器出口NOx排放浓度和锅炉效率的影响,得到较为合理的运行方案:锅炉在300MW负荷运行时,炉膛氧量控制在3.0%左右;OFA风门开度应在90%左右;建议采用BCDE磨煤机组合方式。The combustion optimization adjustment experiments were performed on a 300MW coal-fired boiler after low-NOx combustion retrofit. By studying on the effects of furnace oxygen amount, OFA damper opening degree and mill combination on NOx emissions of economizer outlet and boiler efficiency, the reasonable running modes are found： furnace oxygen amount should be controlled in about 3.0% when the boiler load is 300MW; OFA throttle opening degree is prefer-ably in about 90%; BCDE mill combination mode is suggested.
