What are the hazards of insufficient fluidization air at the bottom of the return conveyor in a circulating fluidized bed boiler?
When the flow rate of air used for fluidization at the bottom of the regenerator is too low, the bed material inside the regenerator cannot be fluidized, which leads to blockages in the regenerator, abnormal material return, and difficulties in controlling the bed temperature and pressure.
