Circulating fluidized bed boiler water cooling wall wear problem

　　Circulating fluidized bed boiler is mainly used in thermal power industry, due to the characteristics of circulating fluidized bed boiler itself, its water-cooled wall wear problem has become a common problem, and has been plagued by major thermal power plants.

　　Circulating fluidized bed boiler water-cooled wall wear problem is a common problem, mainly because in the boiler operation of high-speed movement of material particles in the furnace chamber on the water-cooled wall constantly scouring and cutting, and eventually lead to water-cooled wall tube wear rupture burst tube. In particular, some power plants use a particularly poor quality of coal, so the boiler water-cooled wall wear will be more serious than the average boiler, the average 2-3 months will burst once. As long as the burst tube power plant will need to stop the furnace maintenance, which not only increases the cost of power plant maintenance, but also seriously affects the work plan of the power plant. So for power plants, there are technologies to completely solve the circulating fluidized bed boiler water-cooled wall wear problem for the power plant is a technological innovation.

　　Water-cooled wall wear has existed for many years, and there has never been a technology that can completely cure the water-cooled wall wear problem. Although spraying and other water-cooled wall anti-wear technology can solve the problem of water-cooled wall wear, but only to treat the symptoms but not the root cause. In order to completely cure the circulating fluidized bed boiler water-cooled wall wear problem, we introduced the grille anti-wear technology, by installing grille alloy plate on the water-cooled wall, avoiding the scouring and cutting of the water-cooled wall by the material particles moving at high speed in the furnace chamber, thus completely curing the water-cooled wall wear problem.

　　With the introduction of grating anti-wear technology, the water-cooled wall grating anti-wear technology has been a subversive innovation, from the previous passive anti-wear, to the current active anti-wear. From the previous treatment of the symptoms but not the root cause, to the present both the symptoms and the root cause. With the escort of the grille anti-wear, the power plant successfully and completely away from the circulating fluidized bed boiler water-cooled wall wear problem.
