Zusammenfassung: | A COMBUSTION SYSTEM (1) CAPABLE OF DECREASING NITROGEN OXIDE DISCHARGED FROM EXHAUST GAS IS PROVIDED. THE COMBUSTION SYSTEM (1) INCLUDES: A COMBUSTION FURNACE (2) HAVING A BURNER UNIT (2A) FOR SUPPLYING FUEL AND COMBUSTION OXYGEN TO THE INSIDE OF THE FURNACE, A REDUCTION ZONE FORMED ON A DOWNSTREAM SIDE OF THE BURNER UNIT (2A) FOR COMBUSTING THE FUEL, AND A COMBUSTION OXYGEN SUPPLY PORT (2B) FOR SUPPLYING COMBUSTION OXYGEN (21) SO THAT UNBURNED FUEL WHICH HAS PASSED THE REDUCTION ZONE COMPLETELY COMBUSTS; AND A SMOKE REMOVAL DEVICE (9) FOR REMOVING SMOKE IN THE EXHAUST GAS DISCHARGED FROM THE COMBUSTION FURNACE (2). PART OF EXHAUST GAS (22) DIVERGING FROM BETWEEN THE COMBUSTION FURNACE (2) AND THE SMOKE REMOVAL DEVICE (9) IS INTRODUCED TO THE BURNER UNIT (2A), WHILE PART OF EXHAUST GAS (23) DIVERGING FROM A DOWNSTREAM SIDE OF THE SMOKE REMOVAL DEVICE (9) IS INTRODUCED TO THE COMBUSTION OXYGEN SUPPLY PORT (2B). |
