BIOMASS GASIFICATION POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a biomass gasification power generation system efficiently producing a fuel gas of methane, hydrogen or the like by gasifying biomass by supercritical water while efficiently utilizing energy, and supplying electric power generated by the obtained fuel gas.

SOLUTION: This biomass gasification power generation system comprises: a pretreatment device for preparing slurry of biomass; a reactor for gasifying a slurry member of biomass; a power generater for generating power while applying the produced gas produced by the reactor as a fuel; and a heater for heating the reactor by burning a part of the produced gas in a gas including oxygen. A system obtained by further providing the system with a preheater for preheating the gas including oxygen by utilizing the heat of an exhaust gas produced by burning the produced gas in the heater, comprises; a preheater for preheating the gas including oxygen used in the heater by utilizing the heat of the exhaust gas discharged from the power generater; or a means for heating the biomass in a pressure hydrothermal liquefaction reactor.
