Boiler Abrasion-Resistant Coating

What is boiler abrasion-resistant spray, and what role does adding an abrasion-resistant coating to the boiler surface during use play?

The working principle of a boiler during regular operation is to run under high temperature and pressure, during which it experiences a certain degree of corrosion and wear. The heating surface of the boiler (such as water-cooled walls, economizers, etc.) is long-term subjected to the abrasion of ash particles carried by high-temperature flue gases. Without protection, this can lead to wall thinning or even pipe bursts. Pipe bursts caused by wear can result in unplanned shutdowns, severely affecting the safety and production of power plants. Anti-wear measures can extend the life of the boiler, reduce maintenance costs, and minimize downtime losses. Boiler surface coating involves applying a protective layer to the boiler, isolating the metal from corrosive agents and thereby protecting the boiler to extend its lifespan.

The boiler abrasion-resistant spray coating offers multiple anti-abrasion solutions based on different wear mechanisms. The coating surface boasts sufficient hardness, resistant to erosion wear. High bonding strength ensures thorough fusion with the base material, preventing flaking and peeling. Its coefficient of thermal expansion is close to that of the base material, preventing peeling and cracking during temperature changes such as heating or shutdown. High thermal conductivity does not interfere with the boiler's heat collection.
