沙角C电厂#2锅炉氧量补偿控制策略的改进

Improvement of oxygen compensation control strategy for boiler No.2 in Shajiao C Power Plant

沙角C电厂#2锅炉原氧量补偿控制策略不能适应负荷及煤种的变化,造成风机负荷加重,提出了一种根据煤种、磨煤机组合、升/降负荷进行氧量补偿的自适应控制方案,在实际应用中取得了很好的效果。

The original oxygen compensation control strategy for boiler No.2 in Shajiao C Power Plant can not adapt to the load variation and the coal grad variation,which increases the load of the fan.According to the coal grade,the mile combination and the load increasing or decreasing,a self-adoptive control scheme of oxygen compensation was put forward.In practical application of the scheme,favorable effect was obtained.
