Abstract
This invention comprises a surface heating blanket assembly useful for soil remediation. The assembly principally comprises a metallic furnace belt with tubular electric heating elements inserted between the rungs thereof and making low resistance contact therewith. The furnace belt heater is capable of being rolled and dragged, and flexibly conforms to the earth's surface for maximum heat transfer to the soil. A layer of permeable insulation and an impermeable sheet may be placed on top of the heater. A vacuum may be pulled under the impermeable layer by means of a hole therethrough connected to a vacuum pump.
