Grille anti-wear technology why can completely solve the cfb boiler water-cooled wall wear problems

　　Circulating fluidized bed boilers, also known as cfb boilers, are now more widely promoted and used in the thermal power industry. Its advantages are environmental protection, energy saving, cleanliness and low emission, and it is the boiler equipment of choice for thermal power plants at present. But for the use of cfb boiler power plants also have to face the problem of its water-cooled wall is easy to wear leading to leakage and burst tube occurrence, cfb boiler water-cooled wall is easy to be worn, seriously affecting the safety and economy of the boiler, if the power plant can not solve the problem of water-cooled wall wear in a timely manner will cause huge economic losses.

　　What are the main causes of cfb boiler water-cooled wall wear leaks!

　　cfb boiler water-cooled wall wear is caused by the high-speed movement of material particles in the furnace chamber on the water-cooled wall tube for a long time, the high-speed movement of material particles on the water-cooled wall of long-term scouring led to water-cooled wall wear, thinning, until the water-cooled wall burst tube leakage. Water-cooled wall wear leaks can be divided into.

　　1, the boiler chamber corners of the water-cooled wall because of irregular wear resulting in leaks burst pipe;

　　2, the top of the furnace chamber due to poor sealing leakage of ash resulting in leakage;

　　3, the dense phase area, the furnace chamber exit water-cooled wall laid refractory material off the water-cooled wall tube wear leakage;

　　4, the furnace exit near the back wall, side walls due to changes in the direction of the flue gas caused by water-cooled wall bias grinding leakage.

　　Through the study of cfb boiler water-cooled wall wear leakage, only the initiative can completely solve the problem of wear leakage. Therefore, the grille anti-wear technology was developed and widely promoted and applied. The technology book changed the traditional passive anti-wear and changed the passive into active. By installing alloy grating plates to form a mesh grating, the speed of material particles on the surface of the water-cooled wall is successfully and effectively reduced, blocking the formation of wall flow and successfully solving the problem of water-cooled wall wear in cfb boilers.
