Abrasion-resistant plastics for CFB boiler is an important refractory material, mainly including high-aluminum materials such as corundum. Corundum has the characteristics of high hardness and good wear resistance. Its high alumina content can effectively resist high temperature and wear. It is specially designed to resist the strong wear caused by the high-speed flow of materials in circulating fluidized bed boilers. During the operation of the boiler, the material continuously circulates and washes the furnace wall and other parts. Wear-resistant plastic can effectively reduce wear and extend the service life of the equipment. It is often used in the lining of circulating fluidized bed boilers, such as furnaces, cyclone separators, return feeders and other parts. These parts are greatly affected by harsh conditions such as material washing and high temperature, and wear-resistant plastic can play a good protective role.
