Boiler deoxidizers are used to remove oxygen from boiler water to prevent corrosion and oxidation of the boiler. The following are several common boiler deoxidizers:
Sulfate based deoxidizers: Sulfate based deoxidizers typically contain components such as sulfite or sodium sulfite, which can react with oxygen to form insoluble sulfate precipitates, thereby removing oxygen from water. Sulfate based deoxidizers have high deoxygenation efficiency and relatively low cost.
Polymer adsorbent: Polymer adsorbent is generally a water-soluble polymer that can reduce the oxygen concentration in water by adsorbing oxygen molecules. This deoxidizer forms a protective film in boiler water, which can reduce the corrosive effect of oxygen on metal surfaces.
Foaming agent: Foaming agent can isolate oxygen and reduce oxygen concentration by generating a large number of tiny foam in boiler water. Foaming agents are generally made of organic compounds and have good deoxygenation effects.
High temperature chemical deoxidizer: High temperature chemical deoxidizer is usually added during boiler operation to remove oxygen by reacting with oxygen in water. These deoxidizers can work stably under high temperature conditions and have good deoxygenation effects.
It is necessary to select appropriate deoxidizers based on the specific situation and requirements of the boiler, and follow relevant usage methods and recommendations. In addition, when using deoxidizers, attention should be paid to dosing according to the dosage and operating requirements, and regular monitoring of water quality and inspection of boiler corrosion.
