The boiler wear-resistant castable is a functional material for adjusting the internal temperature of the circulating fluidized bed boiler, improving the economic operation capacity of the fluidized bed boiler, and optimizing the internal structure of the circulating fluidized bed boiler. It is necessary for the installation and overhaul of the circulating fluidized bed boiler. The key link of importance, the construction of boiler wear-resistant castables is directly related to the stable operation of fluidized bed boilers. The various problems of boiler wear-resistant castables can also cause friction and loss in circulating fluidized bed boilers, resulting in circulating fluidization. Safety problems and economic operation problems of bed boilers.
In the overhaul process of boiler wear-resistant castables, if there is insufficient temperature, frequent start and stop, etc., the peeling and falling off of the wear-resistant castable of the boiler will occur, which will not only cause the boiler to lose the protection of the wear-resistant castable, but also affect the circulation flow. The whole of the chemical bed boiler. During overhaul, if the boiler wear-resistant castable project does not follow the necessary techniques and indicators, it will cause the boiler wear-resistant castable to crack and detach.
During the pouring process of the wear-resistant castable of the boiler, loosening and detachment of the nails occur, and the fixing and connecting functions of the nails cannot be exerted, and the vibration of the wear-resistant castable of the boiler may occur, which may also cause excessive wear. In the secondary pouring of the boiler wear-resistant castable, if the secondary treatment is not carried out, the wear-resistant castable of the boiler will fall off during operation, which will bring huge safety hazards to the normal operation of the circulating fluidized bed boiler. Dongyang refractory material This construction site is a cyclone separator and an economizer, which is responsible for the anti-wear measures of the refractory part. Under the coordination of Manager Guo of the Construction Department, the task was successfully completed, and both the owner and the supervision unit gave praise.
