With the improvement of the level of industrialization, the use of modern industrial boilers is becoming more and more extensive. During the operation of industrial boilers, it is not only required to efficiently complete energy conversion, but also to ensure their safety and reliability and reduce maintenance costs. However, oxygen and other impurities in the water during the operation of the boiler will bring corrosion, leakage and other safety hazards to the boiler, affecting its production efficiency and service life. In order to solve this problem, the boiler deaerator came into being.

so-called boiler deaerator, is a specially designed for the boiler and the removal of oxygen in the water equipment. It discharges the oxygen in the water by physical or chemical means, so as to achieve the effect of reducing boiler corrosion and leakage. So, what exactly is the working principle of the boiler deaerator?

we need to understand that oxygen is one of the main causes of boiler corrosion and leakage, and its presence will react with the metal structure to form oxides and accelerate the process of metal corrosion. Therefore, the removal of oxygen in water is an important measure to prevent boiler corrosion and leakage. The working principle of

boiler deaerator is divided into two categories: physical deaeration and chemical deaeration.

physical oxygen removal mainly uses physical methods to separate oxygen. Common methods include pressure change method, separation method, adsorption method and membrane method. Among them, the pressure change method is the most commonly used physical oxygen removal method, which dissolves the oxygen in the water into the gas by repeatedly contacting the water flow and the air flow, and then discharges the oxygen to achieve the purpose of oxygen removal.

chemical oxygen removal is the use of chemical reaction to remove oxygen, the main use of reducing agents (such as ferrous sulfate, sodium hypochlorite, etc.) to reduce the oxygen in the water to harmless water, so as to achieve the effect of oxygen removal.

No matter which method is adopted, the main purpose of the boiler deaerator is to remove oxygen in the water, reduce boiler corrosion and leakage problems, and protect the safe operation of the boiler. At the same time, deoxygenation can effectively improve the thermal efficiency of the boiler, reduce energy consumption and reduce operating costs, and is one of the indispensable key equipment for modern industrial boilers. Although there are many working principles of

boiler deaerator, no matter what method is used, its main purpose is to protect the safety of the boiler, extend its service life, and make it more efficient to complete the energy conversion. In the future industrial development, boiler deaerators will be more popular, providing better service for the production and development of industrial boilers.
