摘要： 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.

摘要： Provided is a method of easily and efficiently removing radioactive cesium from a waste contaminated with radioactive cesium. The method of removing radioactive cesium includes a heating step of heating a waste contaminated with radioactive cesium and a CaO source and/or a MgO source at a temperature of from 1,200 to 1,350°C to volatilize the radioactive cesium in the waste. In the heating step, the kinds and the blending ratios of the waste, the CaO source, and the MgO source are set so that the masses of CaO, MgO, and SiO 2 satisfy the equation: (CaO+1.39×MgO)/SiO 2 )=1.0 to 2.5 (in the equation, CaO, MgO, and SiO 2 represent the mass of calcium in terms of an oxide, the mass of magnesium in terms of an oxide, and the mass of silicon in terms of an oxide, respectively).
