自备电厂次中压发电锅炉水处理问题探讨

A Simple Discussion on Water Treatment of Sub-medium Preeure Power Boilers for Self-Supplied Power Plant

自备电厂次中压发电锅炉过热器经常发生爆管事故 ,其主要原因常与锅水水质不良 ,导致过热器内壁积附盐垢后产生局部蠕变变形 ,最终促使管壁爆破有关。本文结合上述原因的分析 ,对自备电厂次中压发电锅炉水处理问题提出了具体看法。

The main reason,which the accident of tube rupture on super heater often occurs in self-supplied power plant,is water-feed of bad quality.As the salt-dirt depositing in the tube of the super heater,the partial creep deformation takes place gradually and the tube burst in the end.In this paper,some practical measures on water treatment are given and the mentioned reason is analyzed.
