To reduce the area of a site required for ash melting equipment by reducing the total energy required for ash melting without performing ash melting before starting power generation.
There are provided a refuse incinerator 1 where remaining heat recovery equipment 16 and power generating equipment 19 are provided, and a plasma ash melting furnace 2 for melting ash 12, 25 discharged from the incinerator 1. A bypass 27 is provided at an outlet 16a of the remaining heat recovery equipment 16 and is opened and closed with a partition plate 26, an end of which bypass 27 is connected with an ash melting burner 28 provided on the plasma ash melting furnace 2. When the power generation equipment 19 does not generate electricity, the incinerator 1 is operated in a low air ratio, and a waste gas line 20 is defined with the partition plate 26. High calorie gas 38 obtained from the incinerator 1 is supplied as a fuel to the burner 26 through the bypass 27 from the outlet 16a of the remaining heat recovery equipment 16, while increased uncombusted carbon in main ash 12 obtained from the incinerator 1 is supplied as an ash melting heating source of the plasma ash melting furnace 2.
