SYSTEM FOR GASIFYING BIOMASS FUEL AND SYSTEM FOR SYNTHESIZING CHEMICAL PRODUCT BY USING GASIFIED GAS

摘要

PROBLEM TO BE SOLVED: To provide a system for gasifying a biomass fuel by which the efficiency of the system can be improved by efficiently using steam, and to provide a system for synthesizing a chemical product by using the gasified gas.SOLUTION: A system for gasifying a biomass fuel includes a biomass-gasifying furnace 12 for gasifying, for example, biomass 11 of an organic fuel, a gas cooler 14 for cooling a formed gas 13A from the biomass-gasifying furnace 12, a gas-refining apparatus 15 for removing smut in a formed gas 13B after cooling, a second booster 30 for pressurizing a formed gas 13C after the removal of the smut, a chemical product-synthesizing apparatus 32 for synthesizing a chemical product by using a pressurized gas 31, a steam-feeding line Lfor feeding steam 21 (e.g. at 150-170°C) to the gas cooler 14 from the exterior, and a steam-introducing line Lfor introducing high-temperature steam (e.g. at 500°C) obtained by cooling the formed gas 13 by heat exchange at the gas cooler 14 into the biomass-gasifying furnace 12 as a gasifying agent 22A.
