<p>PROBLEM TO BE SOLVED: To provide a reductive oiling system for waste plastics which ensures a sufficient oiling ability and facilitates stirring operations in a melting tank, cleaning and maintenance in a thermal decomposition tank. SOLUTION: This reductive oiling system for waste plastic has the melting tank 2 which has the first crucible 4 received on the inside of the first coil 3 and in which a high frequency electric current is allowed to flow in the first coil 3 to induce-heat the first crucible 4, thus melting a waste plastic in the first crucible 4 to obtain the melted plastic, and the thermal decomposition tank 5 which has the second crucible 7 received on the inside of the first coil 6 and in which a high frequency electric current flows in the first coil 3 to induction-heat the second crucible 7, thus thermally decomposing the melted plastic in the second crucible 4 to produce the decomposition gas G.</p> |
