蒸汽鍋爐易被腐蝕的地方

蒸汽鍋爐停用后有些部位仍然泡在說中的話,水汽經過不斷的蒸發,會使得水汽系統產生大量的濕氣,導致鍋爐產生腐蝕現象。鍋爐使用企業對于鍋爐的很多部位都了如指掌,但是蒸汽鍋爐主要發生腐蝕的部位有哪些呢?
   
1、鍋爐的省煤器部位,在運行中其入口的地方都非常容易腐蝕,停爐后的省煤器就會更容易受到腐蝕了。
Economizer parts of the boiler in operation where its entrance are very susceptible to corrosion, economizer after shutdown would be more susceptible to corrosion up. 
2、在水冷壁運行的時候由于除氧效果不佳,它的汽包和下降管是十分容易腐蝕的。在運行時就易腐蝕,在停爐后水冷壁汽包的側邊尤其嚴重。
Wall run when the results are poor due to oxygen, it's drum and drop tube is very easy to corrosion. At runtime on perishable, in the sides of the drum after the shutdown Wall is particularly serious.  
3、在蒸汽鍋爐的立式過熱器的彎頭地方,因為長期放在水中,積水除不干凈也導致了它腐蝕加快。
In the vertical steam boiler superheater elbow place, because the long-term on the water, the water is not clean in addition it has also led to erosion accelerated.   
4、再熱器和立式過熱器一樣,都是彎頭部位浸沒在水中受到腐蝕。
Vertical superheater and reheater unit, are immersed in the water by the elbow portion of the corrosion.
