deaeration ordinarily reduces oxygen to a residual of less than 0.04 mg/L. In a multistage deaerator, the amount of oxygen can be further reduced to 0.007 mg/L or less. Since the maximum oxygen content of higher pressure boilers should be between 0.005 and 0.007 ppm (as mg/L), both deaeration and chemical treatment are usually necessary.
