Anti-wear issues for boiler evaporation tubes
Thread Content
Which marine enthusiast uses the circulating fluidized bed boiler produced by Beijing Bawei? This boiler features a tower-style design and includes an additional set of evaporation tubes, which is one of the differences it has compared to domestic high-temperature separators. Let’s discuss what anti-wear measures can be taken for these evaporation tubes It is discussed from two aspects: 1) how to enhance wear resistance of the equipment, and 2) how to reduce wear during operation
Weld anti-wear fins (usually forged materials such as 16Mn) on the windward side of the heated surface, or apply anti-wear coatings； In terms of boiler operation, it is necessary to control the particle size of the fuel so as to minimize the amount of unburned solid particles in the gas reaching the group of evaporation tubes; meanwhile, the circulation rate of the flue gases also needs to be controlled.
Apply anti-wear putty in areas of the evaporation tube where wear is likely to occur!
Anti-wear sleeves can be added to the worn side of the evaporation tube, or anti-wear angle steel can be welded there. Additionally, during operation it is important to ensure 1) complete combustion of the fuel, with as little large-particle coal dust as possible. 2. Adjust the blast fan airflow appropriately.
