Abstract: Provided is cement burning apparatus 1 comprising a dryer 6 for drying high-water-content organic waste of which water content is 40 mass percent or more, in which combustion gas extracted from outlet portions or ceiling, portions of preheater cyclones 3A to 3D of a cement kiln 2 is fed to the dryer 6. As the dryer 6, a grinding-type flash dryer, which directly contacts the combustion gas G with the high-water-content organic waste W while grinding it, can be used. In addition, the apparatus 1 further comprises a coarse powder separator 12 for separating coarse powder from the combustion gas extracted from the range described above, and the combustion gas G from which dust is separated by the coarse powder separator 12 can be fed to the dryer 6, and the dust concentration of the gas fed to the dryer 6 may be adjusted to 0.05kg/Nm3 or more and 0.35kg/Nm3 or less.

Abstract: To provide a cement burning apparatus and a method of method of drying high-water-content organic waste capable of drying organic waste with high water content precluding the possibility of explosion; not incurring decreased thermal efficiency of a cement kiln; and more efficiently drying organic waste with high water content. The cement burning apparatus 1 comprises a dryer 6, to which combustion gas is fed from an exhaust gas passage, which runs from an outlet duct of a calciner 4 to an outlet duct of a preheater 3 of a cement kiln 2, for drying high-water-content organic waste of which water content is 40 mass percent or more. As the dryer 6, a grinding-type flash dryer, which directly contacts the combustion gas G with the organic waste W and dries the organic waste W while grinding it, can be used.

Abstract: To provide a cement burning apparatus and a method of drying high-water-content organic waste capable of reducing a danger of explosion at a facility for drying; avoiding decreased value of dried sludge as a fuel: and more efficiently drying high-water-content organic waste. The cement burning apparatus 1 comprises a dryer 6 for drying high-water-content organic waste of which water content is 40 mass percent or more, in which combustion gas extracted from outlet portions or ceiling portions of preheater cyclones 3A to 3D of a cement kiln 2 is fed to the dryer 6. As the dryer 6, a grinding-type flash dryer, which directly contacts the combustion gas G with the high-water-content organic waste W while grinding it, can be used.
