When the circulating fluidized bed boiler is overhauled, the stainless steel protective tile is used in the maintenance process of the boiler, which is located at the bottom 1.2m of the water wall tube. This protection effect is not very obvious. The protective tile often appears during use. Shedding phenomenon. It is recommended that when repairing the fluidized bed boiler, replace the original stainless steel cover with stainless steel wire, the material of which is 309, ϕ3.5mm, and the use of stainless steel wire has a better maintenance and protection effect.

The main function of the cyclone separator is to separate the fly ash and materials from the discharged flue gas. The cyclone separator completes this function by forming a high-speed airflow through high-speed rotation. If the cyclone separator has air leakage, the aerodynamic field inside the separator will change accordingly, and the efficiency of the separator will be reduced, which will eventually lead to an increase in the concentration of fly ash separated by the cyclone separator. The vertical well concentration will increase accordingly.
