NOVELTY - Biomass charcoal (2) is obtained by carbonizing biomass (1) using a carbonization furnace (10). Air flow conveyance of biomass charcoal is carried out using exhaust gas (3) containing tar generated during carbonization and collected in a carbonized-material filling tank (21), and a filled layer (29) of biomass charcoal is formed in the tank. Tar is contacted with biomass charcoal when the exhaust gas passes in the lower portion from the upper portion of the filled layer. At least one portion of tar is adhered to the biomass charcoal.    USE - Manufacture of biomass charcoal for use as fuel.    ADVANTAGE - The method enables efficient manufacture of biomass charcoal having high calorific value, with high yield. Since tar is used effectively, burden of tar process is eased. Dry distillation product is lightened and waste-gas treatment is reduced. Recycling of biomass is accelerated and carbon-dioxide emission is reduced. The manufacturing apparatus has a simple structure.    DETAILED DESCRIPTION - Biomass charcoal is obtained by carbonizing biomass using a carbonization furnace of a fluidized-bed system. Air flow conveyance of biomass charcoal is carried out using exhaust gas containing tar generated during carbonization and discharged from the furnace and collected in a carbonized-material filling tank, and a filled layer of biomass charcoal is formed in the tank. Tar is contacted with biomass charcoal when the exhaust gas passes in the lower portion from the upper portion of the filled layer. At least one portion of tar is adhered to the biomass charcoal. An INDEPENDENT CLAIM is included for manufacturing apparatus of biomass charcoal, consisting of a carbonization furnace of fluidized-bed system, carbonized-material filling tank, a partial-combustion device (22) which burns the gas passing through the filling tank at excess air ratio of less than 1, and a gas flow path which supplied the gas emitted in combustion of the combustion device to the lower portion of the furnace.
