Title:
CEMENT CLINKER PRODUCTION SYSTEM
Document Type and Number:
Japanese Patent JP2022096064
Kind Code:
A
Abstract:
To provide a cement clinker production system capable of obtaining gas containing carbon dioxide gas of a high concentration by increasing a carbon dioxide gas concentration of a part of exhaust gas.SOLUTION: A cement clinker production system 1 includes: a cyclone type pre-heating device 2 for pre-heating a cement clinker raw material; a rotary kiln 3 for burning the pre-heated cement clinker raw material so as to obtain cement clinker; a calcining furnace 4 for accelerating decarbonation of the cement clinker raw material; a clinker cooler 5 for cooling the cement clinker; kiln exhaust gas discharge passages 6a to 6e for discharging exhaust gas generated in the rotary kiln 3; a combustion supporting gas supply device for supplying combustion supporting gas increased in an oxygen concentration compared to air; a combustion supporting gas supply passage 8 for guiding combustion supporting gas to the furnace; and a furnace exhaust gas discharge passage 9 for discharging exhaust gas generated in the calcining furnace 4 (limited to being different from the kiln exhaust gas discharge passage 6).SELECTED DRAWING: Figure 1
