Influence of CO2 inleakage on the slight-alkalization of generator internal cooling water
文献摘要：
The slight-alkalization of generator internal cooling water(GICW)is widely used to inhibit the corrosion of hollow copper conductor and thereby ensure the safe operation of the generator.CO2 inleakage is increasingly identified as a potential security risk for GICW system.In this paper,the influence of CO2 inleakage on the slight-alkalization of GICW was theoretically discussed.Based on the equilibriums of the CO2-NaOH-H2O system,CO2 inleakage saturation was derived to quantify the amount of the dissolved CO2 in GICW.This parameter can be directly calculated with the measured conductivity and the[Na+]of GICW.The influence of CO2 inleakage on the slight-alkalization conditioning of GICW and the measure-ment of its water quality parameters were then analyzed.The more severe the inleakage,the narrower the water quality operation ranges of GICW,resulting in the more difficult the slight-alkalization condi-tioning of GICW.The temperature calibrations of the conductivity and the pH value of GICW show non-linear correlations with the amount of CO2 inleakage and the NaOH dosage.This study provides insights into the influence of CO2 inleakage on the slight-alkalization of GICW,which can serve as the theoretical basis for the actual slight-alkalization when CO2 inleakage occurs.
