Thermal decomposition apparatus
A thermal decomposition apparatus comprises: a thermal decomposition apparatus mechanism being provided with a thermal decomposition furnace that decomposes a panel having a plastic layer; and a superheated steam generator that generates superheated steam being supplied to the thermal decomposition furnace. A furnace body of the thermal decomposition furnace is provided with an inner wall made of metal having a space for housing the panel, and with an outer wall made of metal enclosing the inner wall. A thermal insulation material layer is provided between the inner wall and the outer wall that encloses the inner wall. A heat storage material layer is provided between the inner wall and the thermal insulation material layer.
