An image heating apparatus includes a cylindrical film, and a heater having a substrate, and a heat generating element provided on the substrate. The heater has an elongated plate-like shape, and a first surface contacting the film, a second surface opposite to the first surface, and a heater lateral surface facing outwardly in a widthwise direction of the heat generating element. A supporting member supports the heater, and includes a recess and a supporting lateral surface that is parallel to and opposes the heater lateral surface. The supporting lateral surface is provided in the recess, and is bonded to the heater lateral surface using an adhesive material. A high heat conduction member has a thermal conductivity greater than a thermal conductivity of the substrate, and contacts the second surface of the heater and is sandwiched between the heater and the supporting member.

An asphalt processing system is formed from a heating chamber, a transfer system and an induction heating system. A plurality of paddles, conveyor flights, or conveyor belts having a U-shaped blade move the asphalt through the system while concurrently mixing the material to ensure consistent temperatures through the asphalt cement. The asphalt is heating using one or more induction heating systems to quickly heat the asphalt to between 300 F. and 350 F. The system can include a convection system designed to collect air from the heating chamber, further heat it, and recirculate the air to enhance the asphalt heating. A water condenser can be employed to remove moisture during air recirculation, reducing moisture content in the asphalt cement. The asphalt cement is optionally then modified by addition of one or more rejuvenation oils. This system is particularly useful for recycled asphalt pavement, but can be used for all asphalt products.

Systems, methods, and apparatuses for treating petroleum in a container are disclosed herein.
