Spraying technology other than boiler anti-wear spraying

       

Metal boiler spraying technology is a widely used technology in industry. With more and more power plants and paper mills adopting circulating fluidized bed boilers, the problem of water wall wear is becoming more and more prominent. Metal boiler spraying is also applied to the water wall of circulating fluidized bed boilers to prevent wear. The application of metal boiler spraying in the anti-wear of circulating fluidized bed boiler water wall is earlier, and good anti-wear effect has been achieved. However, with the increasingly serious and prominent wear of the water walls of circulating fluidized bed boilers in some enterprises, metal boiler spraying can no longer meet the anti-wear requirements of these enterprises. Metal boiler spraying mainly sprays metal wear-resistant materials on the surface of the water-cooled wall, but generally it will fail in about a year, and enterprises need to spray again every year or half a year. The loss of furnace shutdown is huge for enterprises. Overhauling and re-coating metal spraying for anti-wear also requires time, cost and financial resources. For water-cooled wall anti-wear, it is a temporary solution. Since metal spraying can only cure the wear of the water wall of the circulating fluidized bed boiler, is there any other technology that can completely cure the wear of the water wall?

The introduction of grille anti-wear spraying marks that the anti-wear of the water wall of the circulating fluidized bed boiler has entered a new era, from the traditional passive anti-wear to the current active anti-wear. The grid anti-abrasion spraying technology is only aimed at the wear of the water wall of the circulating fluidized bed boiler, and only deals with the wear and tear. Its advantage is that it can completely cure the wear problem of water cooling wall of various types of circulating fluidized bed boilers, and it can be used for a lifetime in one construction. Enterprises do not have to spend a lot of time and money every year on the anti-wear treatment of the water-cooled wall, which well guarantees the normal production and safe production of the enterprise.
