    • 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. 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 0.05 kg/Nm3 or more and 0.35 kg/Nm3 or less.
    • 提供一种水泥燃烧装置和干燥能够降低设备的爆炸危险的高含水量有机废弃物的干燥方法; 避免干燥污泥作为燃料的价值降低:更有效地干燥高含水量的有机废物。 水泥燃烧装置1包括干燥器6,其用于干燥水含量为40质量%以上的高含水量有机废弃物,其中从水泥窑的预热器旋风器3A至3D的出口部分或天花板部分提取的燃烧气体 作为干燥机6,可以使用研磨型闪蒸干燥机,该粉碎干燥机在研磨时与高含水量的有机废弃物W直接接触燃烧气体G。 此外,装置1还包括粗粉分离器12,用于从上述范围提取的燃烧气体中分离粗粉末,并且由粗粉末分离器12分离灰尘的燃烧气体G可以供给到干燥器 可以将供给到干燥机6的气体的粉尘浓度调整为0.05kg / Nm 3以上且0.35kg / Nm 3以下。
