In view of the characteristics of the furnace structure and design data, the circulating fluidized bed boiler has extremely poor operating conditions at the heating surface such as the water wall after it is put into operation, and has been subjected to uneven erosion, wear and tear of rapid high temperature and high dusty flue gas for a long time Corrosion, it is more likely to be thinned by severe abrasion, and it is more likely to cause leakage and pipe burst problems. In order to ensure the safe, stable and economical operation of the boiler, the selection of protective measures is extremely important. According to the prevention status of power plants all over the country, the details of CFB boiler operation, process data and failure mechanism, combined with our company's long-term practical engineering construction experience in this field, carefully analyzed by our company's engineering and technical personnel, the prevention of this position. The scheme has been technically designed, and the water-cooled wall anti-abrasion spraying can be used to carry out prevention and achieve good results, and the service life of the equipment can be greatly extended.

    In the application of large boilers, the water wall is the heating surface arranged on the inner wall surface of the furnace for key water cooling, and is also the key evaporative heating surface of the boiler. The operation of the boiler will cause gas, and the chemical substances in it will inevitably cause corresponding corrosion to the water-cooled wall tube, which will reduce the reasonable carrying capacity of the boiler, reduce the safety of the boiler operation, and also affect the normal operation of the boiler at any time. Therefore, the anti-wear spraying of the boiler water wall is of great significance to the safe use of large boilers.
