Abstract

The present invention relates to an operating method of a gasification-melting furnace for operating said gasification-melting furnace provided with a gasification furnace for gasifying input waste material, a melting furnace configured to burn combustible constituents contained in pyrolysis gas produced in said gasification furnace and introduced in the melting furnace and melt ash in the pyrolysis gas, and a burner for auxiliary combustion provided in said melting furnace, said operating method comprising:
operation of stopping operation of said burner when an operating state of said gasification-melting furnace satisfies a specific burner stop condition;
operation of stopping charge of the waste material into said gasification furnace at a point in time when the temperature within said melting furnace in the vicinity of said burner drops down to a preset waste charging stop temperature after said burner has stopped operating; and
operation of reigniting said burner at a point in time when a cumulative value of the amount of air supplied to an side upstream from said melting furnace from a point in time when the charge of the waste material is stopped reaches a fixed value.
