PROBLEM TO BE SOLVED: To provide a gasification system, which uses a gasification furnace for utilizing organic resources of biomass, refuse, sewer sludge, etc. and coal or the like as hydrocarbon-based solid fuels, as can make effective use of an active charcoal drawn out of a tar absorptioon tower provided in the downstream and as can achieve a comprehensive gasification efficiency by promoting the gasification of char inside the gasification furnace. SOLUTION: The gasification system, which uses a gasification reaction furnace for hydrocarbon-based solid fuels and is provided with an alkali absorption furnace for adsorbing the alkali evaporating at the time of the thermal decomposition of the hydrocarbon-based solid fuels onto char, with a gasification furnace for gasifying the char introduced from the above alkali absorption furnace, and with a combustion furnace for generating a combustive gas by burning the residual char introduced from the above gasification furnace, each of these being connected in this order through the communicating passages, is characterized in that the active charcoal drawn out of the tar absorption tower provided in the downstream is supplied into the above alkali absorption furnace.
