An optimum combination scheme was determined, of which the deflector opening of top mill separator was "6", oxygen content at outlet of economizer 3.
为此确定了一套最优组合方案：上层磨煤机分离器折向门开度为“6”，省煤器出口氧量为3。

The important causes include unsuitable proportion of composite firing, proportion of staged air is to excess, lower furnace temperature and lower oxygen value in furnace outlet.
出现这些问题的原因主要是掺烧比例不当、分级送风比例过大、炉膛温度偏低、炉内整体氧量偏低。
