    The operating parameters of the boiler systems (pressure, temperature) are very important in determining how much inhibitor is required to maintain an acceptable corrosion rate level (less than 1.0 mpy). In low to moderate pressure industrial boiler systems, an initial feedwater inhibitor dosage of 100-500 mg/L (ppm) is recommended [23].

Too much hydrazine is wasteful and costly; too little hydrazine will result in higher amounts of dissolved oxygen passing into the boiler, causing corrosion, and inhibiting the formation of magnetite. Typically, the most effective dosage of hydrazine is 3:1 parts hydrazine to the expected level of dissolved oxygen.
