Abstract:

A method for determining the amount of dissolved oxygen in the aqueous medium from a steam generator system that results from air leakage into the system above the water level in a condensor hotwell and that which results from air leakage below the water level in the condensor. Intentional injection of air above water level and intentional injection of air below water level are effected and resultant dissolved oxygen contents measured. The air leakage rate and dissolved oxygen contents at steady state operation are also measured. From these measurements, the amount of dissolved oxygen resulting from above and below water level are determined mathematically or graphically.
