FIELD NOTE:
Carbohydrazide in BOILER means no oxygen is entering the boiler Carbohydrazide will help to decrease oxygen on HP, LP boiler. Carbohydrazid also called Carbodihydrazide, is a high performance oxygen scavenger which can be used in all types of boilers. Carbohydrazide is a white, water-soluble solid that decomposes upon melting point around 153°C.
Carbohydrazide is used as an oxygen scavenger for high pressure boilers in power plants and other industries to reduce corrosion of metal pipes and fittings.
Valuable Boiler Water Treatment Chemicals :
Hydrazine Hydrate (50 ~ 51% as N2H4) plays very important role for corrosion protection in boilers.

Carbohydrazide can be used as oxygen scrubber as direct replacement for Hydrazine in any boiler without the associated safety hazards and handling precautions. The product is based on volatile chemistry and so leaves no dissolved solids and minimal ammonia to the boiler system.
Carbohydrazide does provide outstanding protection from oxygen corrosion together with excellent feed water and boiler system passivation.Carbohydrazide reacts directly with oxygen. It helps prevent oxygen damage and continues to passivate metal surfaces during wet lay-up. Carbohydrazide can also be used as a curing agent for epoxide-type resins.
