Provided is a gasification system that is suitable for continuous operation and uses a gasification device that can be operated for a long period of time without having to stop to remove slag and clinker. SOLUTION: Solid fuel incorporating biomass, fossil fuel, waste or a combination thereof is oxidized in both a first oxidation zone and a second oxidation zone in which the gas flow is opposite to the first oxidation zone. Combustible gas is discharged from the reduction zone between the zones, acid, particulates or water-soluble toxins are purified from the discharged gas with a water scrubber, and tar and moisture are absorbed and removed from the gas from the water scrubber with a double polymer filter unit. The gasification system discharges the product gas for clean combustion by a gas suction fan. [Selection] Figure 2 |
