Abstract
Reforming of a gasification gas is performed by supplying both a tar-containing gasification gas and oxygen to a reforming furnace and burning a part of the gasification gas to heat an inside of the reforming furnace to a target reforming temperature required for reforming. Oxygen 9 and a first stage gasification gas 3a are supplied to a reforming furnace at an end of the furnace in amounts so as to attain the target reforming temperature required for reforming by combustion of the gasification gas with the oxygen to form a heating zone A in the reforming furnace 1. The remaining gasification gas is supplied as second stage gasification gas 3b to a vicinity downstream of the heating zone A in the reforming furnace 1 to form a reforming zone B.
