Analysis of boiler deaerator principles and effects

Деоксидант котла-It is a chemical agent used by boilers to remove oxygen from water, reduce the oxygen content in water, and achieve the effects of prolonging boiler life, improving thermal efficiency, and reducing boiler corrosion. The principle and effect of boiler deaerator will be analyzed below.

One policy analysis

Soluble oxygen: Soluble oxygen in boiler water is one of the main causes of boiler corrosion and oxidation deposition. The active substances in boiler deoxidizers can react with oxygen to form insoluble oxides, effectively reducing the dissolved oxygen content in water.

Diaphragm separation effect: The active substances in the boiler deoxidizer can form a dense film, preventing oxygen from entering the boiler system from the water. This film effectively isolates the contact between water and oxygen, reducing the negative impact of oxygen on boiler corrosion and oxide deposition.

Chemical reduction: A portion of the active substances in boiler deoxidizers have reducing properties and can react chemically with oxygen to reduce it to harmless substances.

Catalyst: Active substanceOxygen exhaust boilerIt can catalyze the reduction reaction of oxygen in water, accelerate the consumption of oxygen, and thus reduce the oxygen content in the boiler system.

II. Impact analysis

Extending the service life of boilers: Due to the effective reduction of oxygen content in water by boiler deaerators, corrosion and oxide deposition can be reduced, thereby extending the service life of boilers. High oxygen content can cause metal components such as pipes, equipment, and chimneys in boilers to be corroded by oxygen, greatly reducing the service life of the boiler. After use, the deaerator can effectively reduce the corrosion of oxygen on the metal and extend the service life of the boiler.

Improving thermal efficiency: Boiler deaerator can reduce the oxygen content in water, prevent metal oxide deposition from affecting heat conduction, and thus improve the thermal efficiency of the boiler. Oxygen reacts with metals at high temperatures to form oxides, generating thermal resistance and reducing thermal conductivity efficiency. The use of antioxidants can reduce the formation of oxides, improve thermal conductivity, and thus enhance the thermal efficiency of boilers.

Reduce boiler corrosion: Deoxidizers can lower the oxygen content in water and reduce the oxygen corrosion of metals. The chemical reaction between oxygen and metal surface forms an oxide layer, leading to metal corrosion. The use of deoxidizers can effectively reduce oxygen contact, reduce corrosion, and protect boiler metal components.

Preventing boiler scale: The active substances in the oxidant can combine with solid ions in the water to prevent the formation of scale. Punishment is formed by the crystallization of solid ions such as calcium and magnesium ions in water at high temperatures, leading to the formation of scale on the inner walls of pipelines and boiler equipment, which reduces heat transfer efficiency. The use of antioxidants can combine solid ions with active substances, prevent scale formation, and maintain the thermal conductivity of boilers.
