恩德炉洗涤除尘灰水阻垢处理总结

Sum-Up of Inhibition Treatment of Ash Water from Scrubbing of Dust Collector of Ende Gasifier

由于粉煤灰中碱性物的溶出及碳酸盐带入系统,导致除尘冷却水系统存在严重的结垢问题。通过使用阻垢剂,回水系统及恩德粉煤气化除尘装置结垢明显减轻,延长了气化装置及灰水系统安全稳定运行周期。

As alkalies in the coal dust ash dissolve out and carbonates are entrained into the system, serious scaling occurs in the cooling water system of the dust collector. By adding scale inhibitors, scaling decreases markedly in the return water system and the dust collector of the Ende pulverized coal gasifiel＇, and the safe and stable operation cycle is prolonged in the gasifer and the ash water system
