蒸汽锅炉易被腐蚀的地方

蒸汽锅炉停用后有些部位仍然泡在说中的话,水汽经过不断的蒸发,会使得水汽系统产生大量的湿气,导致锅炉产生腐蚀现象。锅炉使用企业对于锅炉的很多部位都了如指掌,但是蒸汽锅炉主要发生腐蚀的部位有哪些呢?
   
1、锅炉的省煤器部位,在运行中其入口的地方都非常容易腐蚀,停炉后的省煤器就会更容易受到腐蚀了。
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、在水冷壁运行的时候由于除氧效果不佳,它的汽包和下降管是十分容易腐蚀的。在运行时就易腐蚀,在停炉后水冷壁汽包的侧边尤其严重。
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、在蒸汽锅炉的立式过热器的弯头地方,因为长期放在水中,积水除不干净也导致了它腐蚀加快。
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、再热器和立式过热器一样,都是弯头部位浸没在水中受到腐蚀。
Vertical superheater and reheater unit, are immersed in the water by the elbow portion of the corrosion.
