PURPOSE: A biomass heat-treating method for combustion for increasing a thermal efficiency and a pellet manufacture method for combustion using the heat-treated biomass are provided to maximize a combustion efficiency due to moisture absorbed by the pallet during storage as physical-chemical characteristics of the pallet changes to hydrophobicity when a raw material for the pallet is heat-treated. CONSTITUTION: A biomass heat-treating method for combustion for increasing a thermal efficiency comprises steps of: supplying a lignocelluloses-based biomass to a heat-treating apparatus, increasing a temperature of the biomass in the heat-treating apparatus to from 60 deg. C to 500 deg. C to remove moisture by sequentially drying the biomass, removing a volatile organic compound, and hydrophobitizing by heat-treating the biomass. In the heat-treating apparatus, an exhaust gas is ejected to a biomass supply unit. The ejected exhaust gas is heated to have a temperature of 300 deg. C to 500 deg. C and supplied to a biomass outlet unit of the heat-treating apparatus after passing through a heat exchanger.
