The hood falling off and the hood duct fracture of the circulating fluidized bed boiler are easy to lead to air chamber slag leakage and furnace shutdown accident,causing a certain impact on the overall operation of the boiler.This paper simulates the working process of the hood and analyzes the causes of the hood falling off and the hood duct fracture in detail.The numerical simulation results show that the cap installation method,primary wind pressure and furnace pressure significantly influence the cap force.The results provide some reference for the practice of hood selection and hood installation.
