壳牌煤气化中的平衡操作

为了保障装置的安全、稳定、长周期运行,通过在实际操作中对工况的调节与对系统的优化,讨论了阀门等设备故障、上下游系统波动等对气化炉压力、汽包压力、氮气/二氧化碳管网压力、煤粉管线流量平衡的影响,分析了气化炉压力、汽包压力、氮气/二氧化碳管网压力、煤粉管线流量失衡对生产的危害,并总结出保持气化炉压力、汽包压力、氮气/二氧化碳管网压力、煤粉管线流量平衡的方法,指出保持这些关键参数平衡对壳牌煤气化装置良好运行的重要意义。

Balance Operation in Shell Coal Gasification

In order to keep device operation safely,stably and chronically,by means of condition adjustment and system optimization in the actual operation,the effects of valves and other equipment fault,the upstream and downstream system fluctuation etc.on the balance of gasifier pressure,steam drum pressure,nitrogen/carbon dioxide pressure and pulverized coal flow were discussed.The imbalance harm to production was analyzed,a method to maintain the balance was summarized.It was pointed out that keeping these key parameters balance had the significance to the good operations of Shell coal gasification plants.
