Oil and gas boilers have the advantages of small floor space, convenient operation and high efficiency. They are widely used in various industries and constantly bring benefits to enterprises. However, during the usage process, the boiler may suffer from corrosion due to factors such as water quality. After corrosion occurs in a boiler, not only does the effective thickness of the metal become thinner, but also the boiler's pressure-bearing capacity is reduced and its service life is shortened. Therefore, it is very important to find out the causes of corrosion and effectively prevent the occurrence of corrosion phenomena.

The reasons for the corrosion phenomenon in oil and gas boilers are as follows:

1. After the fuel is burned, the boiler will produce a large amount of flue gas. The water vapor in the flue gas condenses upon contact with the low-temperature wall surface, and the resulting condensate water can severely corrode the metal surface. Therefore, we should try to reduce the moisture content in the flue gas or increase the temperature of the tube wall of the heating surface to be higher than the dew point temperature.

2. Long-term use of boilers can lead to the formation of scale, which in turn can cause corrosion of metals. Especially, some substances can cause severe corrosion to the heating surface of boilers under high-temperature and high-concentration conditions, such as NaOH, etc. Therefore, we should try our best to prevent the formation of scale or clean it regularly to avoid the occurrence of corrosion.

3. After the boilers stop running, some are filled with softened water while others are exposed to the atmosphere, lacking necessary maintenance. Therefore, we should maintain the boiler regularly.

As important equipment providing power or thermal energy for enterprise production, the operation of oil and gas boilers directly affects the normal operation of the entire production process. Therefore, it is very important to understand the causes of common faults and the preventive measures. This article briefly explains the causes of corrosion phenomena, hoping to be helpful to your work.
