What is the primary role of hydrazine in boiler water treatment?

The primary role of hydrazine in boiler water treatment is to prevent oxidation. In boiler systems, the presence of oxygen can lead to corrosion of metal components, which can significantly damage the boiler and reduce its efficiency and lifespan. Hydrazine serves as an oxygen scavenger, meaning it chemically reacts with dissolved oxygen in the water to remove it. This reaction effectively protects the boiler system from oxidative damage.

By using hydrazine, operators can maintain the integrity of the system and ensure that it operates efficiently, minimizing the risk of costly repairs and downtime. This is crucial in marine engineering and power generation where maintaining high-pressure steam systems is vital for performance and safety.
