| 内容記述 | With a view of elucidating the buffering effect of sodium phosphates in high temperature water, the dissociation constants of phosphoric acid are estimated by using of reported data and isocoulombic equation principle, and then pH of sodium phosphate solutions is calculated at boiler water temperature. The results indicated that in term of pH the sodium phosphate solutions were close to sodium hydroxide solution with temperature raising and the molar ratio of sodium to phosphate was not a significant factor in controlling pH of bulk water at boiler water temperature. This means that there is little need to perform the blow-down of boiler water and reinject di-sodium hydrogen phosphate, even though the hide-out occured, as long as the concentration of phosphate species in boiler water is kept above the lowest level for prevention of hardness ion precipitation. | |||||||||||||
