How to prevent and cure the problems caused by water-cooled wall wear in circulating fluidized bed boilers

　　Circulating fluidized bed boiler water-cooled wall wear problem has become a relatively headache in the thermal power industry, and many expert institutions have conducted research and analysis on water-cooled wall wear. With the circulating fluidized bed boiler water-cooled wall wear problem seriously affects the regular production of power plants or enterprises, many circulating fluidized bed boiler water-cooled wall anti-wear technology has been born.

　　Previously, enterprises circulating fluidized bed boilers encounter water-cooled wall wear problems will generally use metal spraying to solve, metal spraying construction is relatively convenient, but the metal spraying anti-wear effect is limited, can not guarantee long-term water-cooled wall tube is not subject to wear. Metal spraying basically every year to re-spray once, can only treat the symptoms but not the root cause.

Grille anti-wear construction finished the overall effect

　　In order to thoroughly help enterprises solve the problems of circulating fluidized bed boilers, after the study of various circulating fluidized bed boilers, we found that the circulating fluidized bed boiler water cooling wall wear problem is common, which is due to the characteristics of the circulating fluidized bed boiler itself. The use of circulating fluidized bed boiler enterprises will participate in the burning of other impurities, circulating materials in the furnace chamber for high-speed movement, the water-cooled wall constantly impact and cutting, followed by the water-cooled wall thinning until the burst tube rupture.

　　Because the boiler as long as the work, the material movement will not stop, the scouring and cutting of the water-cooled wall will not stop. Metal spraying anti-wear just thicken and enhance the water-cooled wall scouring resistance, but still can not avoid the material attack on the water-cooled wall. For this reason, the water-cooled wall grille anti-wear was developed, through the alloy grille plate to block the material particles on the water-cooled wall scouring and cutting, so as to completely prevent and cure the water-cooled wall wear problems.
