NOVELTY - A manufacturing apparatus of semi-carbonized fuel of biomass has a drying apparatus (10) for heating and drying biomass (1), thermal decomposition apparatus (11) for thermally decomposing the dried biomass (2), and a combustion apparatus (13). Combustion exhaust gas (6) generated in combustion apparatus is supplied and mixed with biomass directly, and biomass is thermally decomposed. Mixture (7) of emitted thermal decomposition gas and combustion exhaust gas (6a) used for heating is supplied to combustion apparatus. The combustion air (8) is supplied to combustion apparatus.    USE - Apparatus for manufacturing semi-carbonized fuel of biomass used as fuel for electric power generation system (claimed).    ADVANTAGE - The apparatus efficiently enables manufacture of semi-carbonized fuel without requiring external heat source. The adhesion of tar and condensed water to pipe is prevented.    DETAILED DESCRIPTION - A manufacturing apparatus of semi-carbonized fuel of biomass has a drying apparatus for heating and drying biomass, a thermal decomposition apparatus for thermally decomposing the dried biomass, and a combustion apparatus for supplying heat to drying apparatus and decomposition apparatus. The combustion exhaust gas generated in combustion apparatus is supplied and mixed with biomass directly, and biomass is heated and thermally decomposed. The mixture of emitted thermal decomposition gas and combustion exhaust gas used for heating is supplied to combustion apparatus. The combustion air is supplied to combustion apparatus, and mixture of gas is combusted to generate combustion exhaust gas. An INDEPENDENT CLAIM is included for manufacture of semi-carbonized fuel. The oxygen concentration of combustion exhaust gas used by thermal decomposition process is set lower than the oxygen concentration of combustion exhaust gas used by drying process.
