Abstract:
1. A method of drying high-water-content organic waste comprising the steps of: extracting only a part of combustion gas of which dust concentration is in a predetermined range from an exhaust gas passage, which runs from an outlet of a preheater cyclone other than a highest cyclone to a portion immediately below a material feed portion of another cyclone immediately above the cyclone; drying high-water-content organic waste of which water content is 40 mass percent or more by using said part of extracted combustion gas; returning the combustion gas to the exhaust gas passage; and discharging dried waste via a fluid passage fluidly separate and isolated from passage that extends between a preheater and a cement kiln.
