Waste Heat Boiler Manufacturer: Maintenance of Waste Heat Boiler Is Very Important

The maintenance of waste heat boilers is very important. A well-maintained waste heat boiler can extend its service life. Perhaps many people are asking, why do waste heat boilers need maintenance? Let's take a look with the editor. After reading it, I believe you should know why waste heat boilers need maintenance.

The maintenance of the boiler after shutdown is mainly to prevent the boiler from being corroded. During the shutdown period, the heating surface absorbs moisture in the air to form a water film. The oxygen in the water film reacts chemically with iron to form rust. If the water in the boiler is not discharged after the boiler is shut down or the water in some parts cannot be drained, causing some metal surfaces to be moistened by water, the metal will also be corroded by dissolved oxygen because a lot of oxygen in the air is dissolved in the water.

After the corroded boiler is put into operation, the rust will increase the depth of corrosion at high temperature, expand the area of corrosion, and the iron oxide will continue to fall off, resulting in a decrease in the strength of the steel pipe, resulting in a shortened service life of the waste heat boiler. Inoperative corrosion is one of the most important forms of metal damage, and its harm is much greater than corrosion during operation. Therefore, doing a good job of shutdown maintenance is an important measure to ensure the safe operation of the boiler. It is of great significance to avoid and slow down the corrosion of the boiler and extend the service life of the boiler.
