<P>PROBLEM TO BE SOLVED: To provide a method for producing biomass charcoal by which the yield of the biomass charcoal is efficiently improved when biomass charcoal is produced by carbonizing biomass by using a carbonization furnace 10 of a fluidized bed system, and to provide an apparatus for producing biomass charcoal used in the method. <P>SOLUTION: The method for producing biomass charcoal comprises carbonizing biomass into biomass charcoal by using a carbonization furnace 10 of a fluidized bed system, and then discharging the biomass charcoal from a bottom part of the carbonization furnace 10. In the method, tar 6 is adhered to the biomass and the biomass charcoal by separating and recovering the tar 6 from an exhaust gas 3 containing tar, which is generated when the biomass is carbonized and exhausted from the carbonization furnace 10, and then supplying at least a portion of the recovered tar 6 into the carbonization furnace 10. It is preferable that the recovered tar is blown together with hot air 5 into the carbonization furnace 10. <P>COPYRIGHT: (C)2011,JPO&INPIT |
