电蒸汽锅炉哪些部位最易腐蚀?

在电蒸汽锅炉被关掉结束工作后,氧气可能会从没有密闭的地方钻进电蒸汽锅炉的汽水系统中,然后融合进锅炉,如果压力和温度在下降的话,那么这些氧气就会凝结成为水汽,然后使得锅炉的金属面受潮,从而导致水膜的产生。如果说,在蒸汽锅炉停用后,有些部位仍然泡在说中的话,然后水汽经过不断的蒸发,会使得汽水系统产生大量的湿气,从而让锅炉产生腐蚀现象。那么电蒸汽锅炉哪些部位最容易腐蚀呢?
1、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。
Reheater and superheater vertical, are immersed in water the elbow corrosion.  
2、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,更加不要说停炉后的省煤器了。
Economizer parts of the boiler in operation, where its entrance are very susceptible to corrosion, not to say more after the shutdown of the economizer.
3、在水冷壁运行的时候,它的除氧效果不佳,所以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。
When the water wall running its poor oxygen effect, so it's drum and fall are very susceptible to corrosion of pipes. At runtime on perishable after shutdown Wall sides of the drum is particularly serious.  
4、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,所以也导致了它腐蚀快。
In the vertical steam boiler superheater elbow place, because long-term on the water, in addition to water is not clean, it also led to its rapid corrosion.
