PROBLEM TO BE SOLVED: To provide a chemical loop type combustion device capable of easily coping with various operation modes while keeping a smooth flow condition of an oxygen carrier in an oxidizing tower and a reducing tower, thus convenience is significantly improved in being used as actual equipment.SOLUTION: In a chemical loop type combustion device A including an oxidizing tower 10 and a reducing tower 20, and constituted to allow an oxygen carrier to be circulated while receiving an oxidizing reaction by an oxidizer in the oxidizing tower and a reducing reaction by a reducer in the reducing tower, both of the oxidizing tower 10 and the reducing tower 20 are provided with exhaust gas recirculation lines 30, 40. The exhaust gas recirculation lines 30, 40 are provided with flow rate control means 32, 42 for controlling flow rates of exhaust gases flowing therein, and the reduction of a flow rate of an oxidizer gas or a reducer gas is replenished by recirculating an exhaust gas thereof. |
