| Abstract: | The underground water whose hardness is 297.7 mg/L and alkalinity is 191.6 mg/L was used as make up water for circulating cooling water. When the enrichment factor was 4.0 ~ 4.2 and the pH value was 8.2 ~ 8.6, a formula mainly consisting of HEDP(5 mg/L), PBTCA(3 mg/L) and AA/HPA(10 mg/L) was used. The results of the operation on the site showed that the corrosion rate of the carbon steel tubes of the heat exchanger in the test was < 0.075 mm/a and the depositing rate was about 10 mcm. |
