Boiler Water Treatment in Marine Boilers - ShipFever

Chemicals Used in Boiler Water Treatment. Various set of chemicals are used for boiler water treatment. Oxygen scavenger such as hydrazine, carbohydrazide, sodium sulphate and tannin is used to remove the dissolved oxygen in the boiler water. This prevent boiler corrosion by removing or reducing oxygen content in the system.
