Calculating Boiler Chemical Requirements – Water

Jun 26, 2017 · D. Hydrazine Calculations. The theoretical dosage of hydrazine ( active) is 1 ppm per ppm of dissolved oxygen. Because of the explosive nature of pure hydrazine, it is available for industrial use in 35% active solutions. It, therefore, takes 3 ppm of 35% active hydrazine to neutralize 1 ppm of dissolved oxygen.

amount of hydrazine. 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.
