Service life of boiler after spraying

       Boiler spraying, thermal spraying, supersonic arc spraying, boiler heating surface anti-wear and anti-corrosion, boiler water wall anti-wear spray, deflector anti-wear, anti-wear plate installation, longitude and latitude anti-wear, grille anti-wear, CFB boiler anti-wear technology

The service life of the boiler after spraying generally has great advantages in terms of energy saving performance, combustion efficiency, fuel applicability, efficient desulfurization and comprehensive utilization of ash and slag due to the characteristics of the furnace structure and design parameters. As everyone knows, the damage of the heating surface of the CFB boiler is very serious. In the high temperature environment of the boiler, the damage is mainly due to the rapid erosion of the wall thickness by the boiling particulate medium. The raw material for the wall thickness is usually No. 20 boiler steel, with low surface hardness and poor oxidation resistance. It is difficult to withstand such damage for a long time. In view of such working conditions, the coating standard has anti-oxidation and anti-particle damage performance at high temperature, and has high bonding strength and deformation coordination ability with the substrate.

Service life of boiler after spraying:



The service life of sprayed 1mm thick coating is one year to one and a half years, and the service life is determined by the detailed working conditions. Smooth transition between coating and wall thickness, no boss phenomenon.



Boiler spraying range and standard:



When the water-cooled wall pipe is damaged greatly, and the wall thickness is less than 3mm, the pipe system should be replaced first, the local damage is relatively light, and the small parts can be ground after welding. The diaphragm installation of the diaphragm wall should be vertical and smooth. Only when the above standards are met can be sprayed.
