[0002] In a circulating fluidized bed boiler and a combustion chamber, the wind cap is one of the key components. It is installed on the air distribution plate, and the main function is to uniformly send the fluidized combustion air into the furnace to ensure that the coal powder in the furnace can be burned in a boiling state. If the wind cap is worn or damaged, it will cause uneven air distribution of the boiler, and further cause serious impact on the operation of the boiler and its furnace wall, etc. Therefore, the performance of the wind cap is crucial to the fluidization quality and safe and stable operation of the circulating fluidized bed boiler.
