摘　　要：本文通过对稀释蒸汽发生器腐蚀管件、腐蚀垢物、腐蚀介质、介质沉积物等成分分析,表明了稀释蒸汽发生器腐蚀主要是由有机物的富集酸解富集造成pH下降引起的,为此指出平稳控制pH值和有机物量是防止腐蚀发生的主要途径。According to a detailed analysis of heat exchanged tube,product,medium,sediments of the dilution steam generating corroded,it was showed that the enrichment and decomposition of petroleum substances in diluted steam generating system caused corrosion by Increased the acidity.The stable monitor of pH value and petroleum substance amount is the main way to prevent corrosion occurring
