ABSTRACT:
A system for gasifying styrofoam and liquefying the resulting gas to a liquid styrofoam. This system is particularly useful for disposition of the styrofoam onto which non-meltable substances adhere. The system includes a pulverizing mechanism for pulverizing a lump of styrofoam and a melting vessel for melting the pulverized styrofoam. The resulting melt is filtered by a strainer to remove the non-meltable substances. The filtered styrofoam melt is transferred to a gasifying vessel for vaporization. The styrofoam gas (combustible gas) is then condensed by a gas cooler. A gas leaking from the melting vessel to the pulverizing mechanism through the constant volume feeder is discharged by a discharge line. The styrofoam gas is a combustible gas so that it may be used as a fuel gas for a gas burner. Part or all of the styrofoam gas is condensed by the gas cooler and recovered as a fuel oil.
