PROCESS FOR PRODUCING CARBONIZED FUEL

PROBLEM TO BE SOLVED: To provide a process for producing a carbonized fuel, which is carbon neutral but can be a substitute for fossil fuel, from a biomass with high water content such as sewage sludge disposal of which is conventionally troublesome and a biomass with low water content, and to provide a device suitable to conduct the process. SOLUTION: The process for producing the carbonized fuel includes a first carbonization step of dry distillation of a biomass with low water content 1 to obtain a first step carbonization fuel 4 and a dry distillation gas 3; a drying step of drying a biomass with high water content 5 by means of heat of a high temperature combustion exhaust gas generated by combustion of the dry distillation gas 3 in the first carbonization step to obtain a dry biomass 6; and a second carbonization step of dry distillation of the dry biomass 6 generated in the drying step to obtain a second step carbonization fuel 7.
