Claim 7:
8. The system according to claim 7, wherein during calcination in the fluidized bed, a bed height of a dense phase increases when U3>Ug>U1>U2, and the bed height increases until a thermal decomposition of Ca/Mg carbonate particles is completed; when the thermal decomposition of the Ca/Mg carbonate particles is completed, calcined Ca/Mg based oxide particles can be entrained and collected by increasing Ug, wherein U1 is the average minimum fluidization velocity of the Ca/Mg carbonate particles, U2 is an average minimum fluidization velocity of Ca/Mg oxide particles, U3 is an entrainment velocity of the Ca/Mg oxide particles, Ug is a fluidization velocity of an inlet fluidizing gas.
