Abstract

PURPOSE: To build the disposing apparatus at low cost and secure safety with the prevention of the outbreak of a fire or the like by performing an incineration of wastes with an internal heating using a high frequency radio wave while a heating is being made at a fixed temperature by an external heat source. CONSTITUTION: When wastes 5 such as paper diaper used are housed into a treating chamber 3 to start the operation of incineration, an external heat source (e.g. gas burner 9) is controlled by a control circuit to heat the inside of the treating chamber 3 while a magnetron 7 is turned ON or OFF at a proper interval to supply a high frequency radio wave to the treating chamber 3. Then, the wastes 5 are dried efficiently by heating with the external heat source 9 and internal heating by the high frequency radio wave from the magnetron 7 are combined to dry the wastes 5 efficiently while an incineration treatment is performed by natural ignition with the proceeding of drying. This enables building of a disposing apparatus 1 at a low cost and securing of safety with the preventing of the outbreak of a fire or the like by incineration.
