Wear-resistant gunning material for circulating fluidized bed is an important refractory repair material specially used for circulating fluidized bed boilers. It usually contains high-aluminum materials, such as brown corundum, etc. It has high alumina content, high hardness, high temperature resistance, and strong wear resistance. It can effectively resist high temperature and material wear in circulating fluidized bed boilers. Construction by spraying and other methods does not require complex molds and support structures, and can quickly and efficiently repair worn parts, reducing boiler downtime and maintenance costs. Moreover, for some parts with complex shapes and narrow spaces, such as corners of water-cooled walls and pipe elbows, gunning materials can better adapt to and cover them. It is mainly used in areas with more severe wear in circulating fluidized bed boilers, such as the dense phase area of ​​the furnace, water-cooled walls, cyclone separators, return feeders, etc. These parts are prone to damage and shedding of lining materials due to long-term scouring and wear of materials. Wear-resistant gunning materials can be used to repair and reinforce them in time.
