PROBLEM TO BE SOLVED: To provide a treatment method and a treatment device of a combustible gas in a waste melting furnace capable of satisfying restriction on chimney dioxin and preventing troubles such as attachment and blockage in a heat exchanger by removing dusts from the combustible gas created in a waste treatment furnace within an optimal range. SOLUTION: In this treatment method of the combustible gas in the waste treatment furnace 1, the combustible gas created in the waste treatment furnace is guided to a dust collecting device 5 to implement dust removing to control a concentration of dust in the combustible gas within a range of 0.02-0.07 kg/Nm<SP>3</SP>, and then the combustible gas after removing dust is burnt at a high temperature. The dust collected by the dust collecting device 5 is supplied to the waste melting furnace from a tuyere 8 of the waste melting furnace 1 to be burnt and melted at a high temperature.
