CEMENT CLINKER PRODUCTION SYSTEM AND CEMENT CLINKER PRODUCTION METHOD
Provided is a cement clinker producing system capable of providing a gas containing a carbon dioxide gas at a high concentration by increasing a carbon dioxide gas concentration for a part of an exhaust gas.A cement clinker producing system 1 includes a cyclone preheater 2, a rotary kiln 3, a calcination furnace 4, a clinker cooler 5, a kiln exhaust-gas discharge passages 6a to 6e, a combustion-supporting gas supply device 7, a combustion-supporting gas supply passage 8, and a calcination furnace exhaust-gas discharge passage 9 (that should be different from the kiln exhaust-gas discharge passage 6). The cyclone preheater 2 is configured to preheat a cement clinker raw material. The rotary kiln 3 is configured to burn the cement clinker raw material that has been preheated so as to provide cement clinker. The calcination furnace 4 is configured to promote decarbonation of the cement clinker raw material. The clinker cooler 5 is configured to cool the cement clinker. The kiln exhaust-gas discharge passages 6a to 6e are configured to discharge an exhaust gas generated in the rotary kiln 3. The combustion-supporting gas supply device 7 is configured to supply a combustion-supporting gas having a higher oxygen concentration than that of air. The combustion-supporting gas supply passage 8 is configured to guide the combustion-supporting gas to the calcination furnace 4. The calcination furnace exhaust-gas discharge passage 9 is configured to discharge a carbon dioxide gas-containing exhaust gas generated in the calcination furnace 4.
