摘要
Provided are fuel feed means 3, an air separation unit 6,air feed means 7, a combustion furnace 11 with a burner 9 for combustion, an exhaust gas line 14 for leading an exhaust gas from the combustion furnace 11 to outside of the combustion furnace 11, exhaust gas treatment means 20a and 20b included in the exhaust gas line 14, and a recirculation line 15 for circulating a portion of the exhaust gas at least exhaust gas treatment means 20a and 20b for recirculation of a portion of the exhaust gas at least dust-removed by the exhaust gas treatment means 20a and 20b to the burner. Further provided are exhaust gas capture means 18 for taking out carbon dioxide gas from a remaining non-recirculating exhaust gas, and carbon dioxide gas feed means 33, 40 and 46 for introducing carbon dioxide gas to equipments 10, 20a and 20b of the oxyfuel combustion boiler facility.
