[PROBLEMS] To appropriately remove impurities such as tar, light oil, and dioxin contained in gas when high calorie and volatile rich waste such as waste tires and waste plastics is gasified to obtain high calorie gas. And the obtained gas can be refined without problems by joining the existing coke oven gas line at the steelworks. A pyrolysis furnace 2 for pyrolyzing and gasifying combustible waste, and a reforming furnace 13 for reforming the pyrolysis gas generated in the pyrolysis furnace 2 by reacting with oxygen and steam, In a gasification gas purification apparatus for purifying a reformed gas generated in the reforming furnace 13 to obtain a fuel gas, a first gas cooler 14 for cooling the reformed gas to 90 to 70 ° C. below a saturation temperature is provided. The gas discharged from the first gas cooler 14 is refined by setting the dioxin concentration to a reference value or less and then joining the steel plant with the coke oven gas purification facility 24 by the dry main 22 attached to the existing coke oven. To do. [Selection] Figure 1 |
