1. a use makes the method for the equipment of at least one oxide circulation therein, described at least one oxide is at two reactors (1,4) in one in, be reduced then at described two reactors (1,4) oxidized in another in, this equipment comprises:

  • for the reactor (1) of reduced oxide, the solid fuel being grated (E1) and oxide (E2) enter this reactor for reduced oxide (1);

    Receive the more inefficient separator (2) from the entrained solids of the described reactor for reduced oxide (1), described more inefficient separator (2) is for isolating oxide (E2) from described entrained solids, the top stream of the solid in the fine particle exit of described more inefficient separator (2) is recycled in greater efficiency separator (6), to isolate solid and solid is introduced to the described reactor (1) for reduced oxide again from gas;

    Carbon separation unit (3), the exit of more inefficient separator (2) described in this carbon separation unit is arranged on, to send into the reactor (4) for making oxide oxidation for the reactor (1) of reduced oxide and by oxide described in carbonaceous particles is sent into;

    And receive from described for making the separator (5) of entrained solids of reactor (4) of oxide oxidation, the method is characterized in that, described in the average particulate diameter of the solid fuel (E1) that enters be controlled so as to than the average particulate diameter of the described oxide entering (E2) to twice when young.
