SYSTEM FOR GASIFYING WASTE

摘要

PROBLEM TO BE SOLVED: To decrease the tar concentration of reformed gas as a whole system without increasing a size of a reforming furnace in a system for gasifying waste.

SOLUTION: The system for gasifying waste has: a gasification furnace 5 for pyrolyzing waste; the reforming furnace 13 for generating the reformed gas by injecting an oxidizer to pyrolysis gas and reforming the pyrolysis gas containing tar; a heat recovery boiler 17 for recovering the heat of the reformed gas; and a bag filter 23 for collecting the dust of the reformed gas discharged from the heat recovery boiler 17. The system for gasifying waste has a supply means for supplying at least either the dust collected by the heat recovery boiler 17 or the dust collected by the bag filter 23 to the gasification furnace 5. The tar concentration of the pyrolysis gas to be supplied to the reforming furnace 13 is decreased by making the tar adsorb on the dust supplied to the gasification furnace 5.
