In this study, a fluidized bed electrified calciner was designed, and various operating conditions were investigated by CPFD simulations. It was found that maintaining a constant fluidization velocity while increasing the temperature of hot cylinders or preheating the raw meal significantly enhances the calcination degree. Altering the fluidization velocity while keeping temperatures constant also greatly affects the calcination degree and particle entrainment. A fluidization velocity of 0.3 m/s appears to be optimal for the reactor, whereas 0.8 m/s resulted in complete entrainment of the bed. The maximum calcination degree achieved was 90% with preheated meal. The average meal residence time was found to be 24-26 s.
