　　The maintenance of the waste heat boiler is very important. A well-maintained waste heat boiler can increase its service life. Maybe many people will ask, why do we need to repair it?

　　Let's take a look below. After reading it, I believe you should know why the waste heat boiler needs maintenance.

　　Maintenance after shutting down the boiler is mainly to prevent the boiler from being corroded. When the boiler is closed, due to the absorption of moisture in the air, a water film is formed on the heating surface, and the oxygen in the water film reacts with iron to form rust. If the water in the boiler is not discharged after the boiler is turned off, or some parts of the boiler cannot be discharged completely, some metal surfaces are still soaked in water. Because a large amount of oxygen is dissolved in the air, the metal will also be corroded by dissolved oxygen.

　　After the corroded boiler is put into operation, the rust will intensify the corrosion at high temperature, expand the corrosion area, and the iron oxide will continue to peel off, resulting in the decrease of the strength of the steel pipe and the shortening of the life of the boiler. Stopping corrosion is one of the main forms of metal damage, and its damage is greater than work damage. Therefore, maintenance and shutdown of the boiler is an important measure to ensure the operation of the boiler. This is of great significance to avoid and slow down boiler corrosion and increase its service life.
