Document Type and Number:
WIPO Patent Application WO/2020/184699
Kind Code:
A1
Abstract:
The present invention provides a method for producing a solid fuel that has improved water resistance, has a woody biomass as a feedstock material, is as pulverizable as coal, and can be mixed with coal and pulverized for use as a fuel for a pulverized-coal boiler. A solid fuel is produced by a method that includes: drying a pulverized woody biomass having a water content of 30-60% and a size of 5-50 mm to a water content of 25% or less at a material temperature of 45-90°C, and calcining at an oxygen concentration of 10% or less and a material temperature of 250-350°C; and forming a molded product having a bulk density (measured by the "Bulk Density Test Method" of JIS K-2151-6) of 500 kg/m3 or higher after pulverizing the resultant calcined product to a size of 10 mm or less.
