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

  • be used for the reactor (1) of reduced oxide, the solid fuel (E1) and the oxide (E2) that are ground enter this reactor that is used for reduced oxide (1);

    Reception is from the more inefficient separator (2) of the entrained solids of the described reactor (1) that is used for reduced oxide, the top stream of the solid of described more inefficient separator (2) is recycled in the greater efficiency separator (6), so that isolate solid and solid is introduced the described reactor (1) that is used for reduced oxide again from gas;

    Carbon separation unit (3), this carbon separation unit are installed in the exit of described more inefficient separator (2), describedly are used for the reactor (1) of reduced oxide and oxide are sent into the reactor (4) that is used for making the oxide oxidation so that carbonaceous particles sent into;

    And receive separator (5) from the entrained solids of the described reactor (1) that is used to make the oxide oxidation, the method is characterized in that the average particulate diameter of the described solid fuel that enters (E1) is controlled so as to than the average particulate diameter of the described oxide that enters (E2) to twice when young.
