Description

HYDRAZINE is an oxygen scavenger for HP boilers.  HYDRAZINE reacts with the oxide film on steel surfaces in a boiler system to form a magnetite layer, which gives metal protection. This "passivataion" technique is useful for pre-treatment of new boiler plant and for protection of boilers during idle and storage periods. HYDRAZINE may be used in all sizes and types of boilers but is particularly suited for use at high pressure where oxygen corrosion becomes rapid and where metallic corrosion products can quickly lead to overheating and failure of generating tubes.

Application Description

HYDRAZINE can be fed neat or in any convenient dilution. Dilution should be carried out using condensate or deaerated water. Initial dosage for untreated system is 100mls per ton of water. Dosage will be increased or reduced in accordance with result of HYDRAZINE test. Generally daily dosage of 1lt. for a boiler 10 tons of water capacity will keep the recommended value.
