PROBLEM TO BE SOLVED: To provide a method for producing wood-derived fuel usable as fuel for a cement kiln by utilizing wood waste. SOLUTION: The wood-derived fuel production method comprises steps of (A) crushing wood by a crusher into crushed wood chips with 100 mm or shorter length, 10 mm or shorter width, and 5 mm or thinner thickness; (B) heating the wood chips for partial thermal decomposition at 200-300°C in a heating furnace so as to achieve 5-25 wt.% of weight decrease ratio; and (C) obtaining, as wood-derived fuel, a fragments of the partially thermally decomposed wood having a grain size of 1.5 mm or smaller by pulverizing the crushed wood after the heating treatment. As the heat source for the heating treatment in the step (B), waste heat of a cement production facility can be utilized. COPYRIGHT: (C)2004,JPO
