<P>PROBLEM TO BE SOLVED: To provide a system that stably carries out carbonization/combustion/gas formation and has high thermal efficiency and generating efficiency even in the case of comprising not only woody biomass but also waste-based biomass such as municipal waste in a processing object. <P>SOLUTION: The biomass power generation system comprises a carbonization apparatus 2 that receives supply of exhaust gas discharged in the operation of a generator 6 and uses waste heat of the exhaust gas so as to thermally decompose and carbonize the biomass without using a subsidiary fuel in a state that waste-based biomass such as municipal waste, etc., is contained in fuel, a gasification furnace 3 that carries out combustion/gasification of carbonized char formed by the carbonization apparatus 2, modification of thermal decomposition gas containing tar volatilized during carbonization and melting/slag formation of ash in fuel and the generator 6 that is operated by using gas formed by the gasification furnace 3 as energy, generates electricity and supplies exhaust gas discharged during the operation as a heat source to the carbonization apparatus 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
