The role of the water-cooled wall of circulating fluidized bed boilers in power plants and the importance of water-cooled wall anti-wear

　　Circulating fluidized bed boiler is a kind of boiler, which is now commonly used in thermal power industry. Water-cooled wall is one of the important parts of circulating fluidized bed boiler, so what is the role of circulating fluidized bed boiler water-cooled wall? Why do power plants need to spend a lot of manpower and financial resources to solve the water-cooled wall wear problem during maintenance?

　　The water-cooled wall for circulating fluidized bed boilers is the main role of: 1, absorbing the combustion exotherm in the furnace, heating water into saturated steam. 2, protecting the furnace wall, simplifying the wall structure, reducing the weight of the wall. 3, cooling the flue gas to a suitable temperature, improving combustion, reducing pollutant emissions.

　　Seeing the above water-cooled wall for circulating fluidized bed boilers, you can understand why power plants spend a lot of material and material resources to solve the problem of preventing water-cooled wall wear. Once the water-cooled wall due to wear problems thinning will lead to rupture, leakage, burst tube, this time the power plant will need to stop the furnace maintenance, spend a lot of money and manpower to solve the problem of leakage burst tube, if the situation is poor may need to replace the new water-cooled wall tube, greatly affecting the economic efficiency of the power plant. This is why power plants now actively seek water-cooled wall anti-wear technology to completely eradicate the problem of water-cooled wall wear and prevent water-cooled wall wear problems.

　　Circulating fluidized bed boiler water-cooled wall under normal circumstances will also be thinning, thinning speed is particularly slow, any item will have a use cycle. But the water-cooled wall wear and tear is an abnormal loss, this needs to be solved. In order to completely solve the problem of water-cooled wall wear and prevent the water-cooled wall because of wear and tear to speed up the normal loss, water-cooled wall grille anti-wear technology is widely used and promoted. At present, the grating anti-wear technology is the only technology that can actively prevent and completely solve the water-cooled wall wear problem. With the practical application of grating anti-wear in major power plants, grating anti-wear technology has become the mainstream circulating fluidized bed boiler water-cooled wall anti-wear technology.
