No oxygen is entering the boiler with the feed water when hydrazine is present in the water.
The objective is to maintain a hydrazine residual between 0.05-0.2 ppm depending on operating pressure and boiler designe. Actual consumption is determined under operating conditions. A normal dosage is approximately 1 ltr. per day, depending of system layout.
Hydrazine is a convenient reductant because the by-products are typically nitrogen gas and water. Thus, it is used as an ANTIOXIDANT, an oxygen scavenger, and a corrosion inhibitor in water boilers and heating systems.
Hydrazine is mainly used as a foaming agent in preparing polymer foams.
No oxygen is entering the boiler with the feed water when hydrazine is present in the water.
Hydrazine is used as an oxygen scavenger for high pressure boilers in power plants and other industries to reduce corrosion of metal pipes and fittings. To test for hydrazine level in boiler we have simple Method, in which simply any non technical person even can perform the test. It is used mostly for the determination of small amounts of hydrazine in boiler feedwater. There are no common interferences. : http://rxmarine.com/hydrazine-test-kit
