What is the importance of ceramic spraying on boilers

Counts:9232023-07-25 15:44:00 Source: 河北中信防腐工程有限公司

When is it necessary to perform ceramic coating on boilers? Firstly, the scope of use of boilers is relatively special. The application fields are mainly between high-temperature applications, high corrosion, and high chemistry. With the continuous erosion of high temperature and other chemical components, especially when the boiler is operating at high temperature, the damage caused by high-temperature corrosion is more complex compared to other factors such as low-temperature corrosion, Over time, it can cause certain damage to the boiler. For coal-fired boilers, such as thermal oil boilers, to prevent high-temperature corrosion and fly ash coking in the convection section, measures such as reducing the furnace outlet smoke temperature and increasing the transverse pitch of the convection section inlet are often taken to prevent high-temperature corrosion. For straw fired boilers, to prevent high-temperature corrosion, the furnace outlet smoke temperature can be controlled not to be too high, So if we add a layer of anti-corrosion process to the inner wall of the boiler, it will greatly reduce damage in later use. Boiler ceramic spraying means that we add non ceramic spraying surface treatment to the boiler body. Spraying simply means spraying a dense protective film on the surface of the workpiece, which can isolate air and prevent rust; And different coatings will have corresponding chemical resistance, Climatology resistance, corrosion resistance, etc.
In the process of boiler ceramic spraying, we choose Thermal spraying, which can also be called surface modification technology spraying. Using DC driven plasma arc as the heat source, we heat ceramics, alloys, metals and other materials to the molten or semi molten state, and spray them at high speed to the pretreated workpiece surface to form a solid surface layer. After processing, the surface of the machine body can be wear-resistant and corrosion resistant, Including high-temperature oxidation resistance, etc.
