To what extent does oxygen affect the service life of a boiler?

Deoxidizer-It is a chemical substance used for boiler water treatment, aimed at removing oxygen from water to prevent metal corrosion and deposition. The use of deoxidizers affects the service life of boilers and can extend their service life and effective operation. This article will provide a detailed introduction to the mechanism, advantages, and impact on the lifespan of boilers.

Firstly, let's take a look at the mechanism of action of antioxidants. When oxygen is present in the water, the metal surface of the boiler will be corroded and damaged by oxygen. Deoxidizer reacts with dissolved oxygen in water, converting it into harmless gas and eliminating it from the system. This chemical reaction helps to protect the metal materials of the boiler and reduce corrosion.

The use of antioxidants has a significant impact on the service life of boilers. Firstly, the deaerator can reduce the corrosion of the boiler. Corrosion of metal surfaces inside boilers is a common problem that can cause equipment damage and require frequent maintenance. Deoxidizers can effectively remove oxygen from water, reduce the corrosion rate of metal surfaces, and thus extend the service life of boilers.

Secondly, deoxidizers help prevent the formation of sediment. The soluble oxygen in boiler water can react with other substances to form sediment and scale. These sediments adhere to the heat transfer surfaces inside the boiler, reducing thermal conductivity and increasing energy consumption, leading to premature equipment failure. The use of deoxidizers can effectively reduce the concentration of dissolved oxygen in water, prevent sediment formation, maintain high thermal conductivity of boilers, and extend the service life of equipment.

Deoxidizers can also improve the thermal efficiency of boilers. During the operation of the boiler, oxygen in the water reacts with carbon dioxide produced during combustion to form acidic substances, increasing the content of carbon dioxide in the flue gas. This may result in boiler flue gas emissions exceeding environmental requirements and reducing combustion efficiency. The use of deoxidizers can effectively remove oxygen from water, reduce the formation of acidic substances, lower the carbon dioxide content in boiler flue gas, improve combustion efficiency, and save energy.

In addition, the deaerator can prevent corrosion and damage to boiler pipelines. The water and heat in the boiler can cause corrosion and erosion in the pipelines. When pipelines experience severe corrosion, problems such as water leakage and collapse may occur, leading to equipment failure and shutdown. In addition to using oxygen scavengers, timely cleaning and maintenance of pipelines are also important measures to reduce corrosion and extend equipment life.

Deoxidizers can also improve the stability of boilers. The oxygen in water can cause boiler overheating, bubble boiling and collapse, reducing the efficiency of boiler thermal energy conversion and making boiler operation unstable. The use of deoxidizers can effectively remove oxygen from water, reduce the formation of bubbles in boilers, and improve the stability and reliability of boiler operation.
