| 摘 要： | 托电#1机严重积盐之后,在#2机组大修前的半年里将炉水的低磷酸盐处理工况改为AVT(O)工况,使得蒸汽携带至汽机的盐分大大减少,叶片上的积盐减少、剥离,所以#2机大修时的积盐量明显小于#1机;但#2机低压叶片和隔板的腐蚀比#1机严重,通过向炉水中加入适量氢氧化钠,提高蒸汽携带至汽机的盐分中碱性成分所占的比例,从而抑制了氯离子对汽机的腐蚀。

| Abstract: | After the serious salt deposit occurred in the unit No.1 of the Tuoketuo Power Generation Co.,Ltd,the low phosphate treatment mode was changed to all volatile treatment(AVT(o)) mode in the boiler of unit No.2 during half a year before its overhaul,the salinity brought into the turbine by steam was decreased greatly,the salt deposit in the blades was decreased and separated.So it has been founded in the overhaul the salt deposit of the unit No.2 was obviously less than that of the unit No.1.However,the corro... |
