PROBLEM TO BE SOLVED: To provide a manufacturing method of a solid fuel that utilizes woody biomass as a raw material, has high material yield and heat quantity yield, has crushability equal to coal, and can be used as fuel of a pulverized coal boiler by mixing with coal and crushing the mixture.SOLUTION: A solid fuel is manufactured by densifying woody biomass ground product whose size is 5-60 mm to a packing density (measured according to JIS K 2151-6 "apparent density testing method") of 0.5 g/cm, and calcinating under a condition that an oxygen concentration is lower than 10%, and a temperature is 170-350°C. |
