THE METHOD FOR MANUFACTURING A REFUSE DERIVED FUEL FROM MUNICIPAL WASTE USING DUAL DRYING SYSTEM AND DUAL EXHAUSTING SYSTEM

PURPOSE: A domestic waste and buried waste-based solid fuel manufacturing method is provided to ensure the uniform quality of waste and to efficiently consume energy. CONSTITUTION: A domestic waste and buried waste-based solid fuel manufacturing method includes: a first classifying step for classifying waste; a first drying step for classifying combustible materials and drying the classified materials with hot water; a step for pulverizing the combustible materials; a step for measuring the moisture content of the pulverized combustible materials; a 2-A drying step for drying the combustible materials with water content more than 10% using heated air; a 2-B drying step for drying the combustible materials with water content more than 25% using heated air; and step for discharging linear pellet type RDF and fluff type RDF according to the moisture content of the dried combustible materials.
