ABSTRACT:
In casting operations using molds made of plastic-bonded sands, the exhaust gases generated from the plastic binder are collected within an enclosure to which the mold passes from a casting location, the gases are mixed with combustion air supplied into the enclosure and an ignition source is arranged within the enclosure to ignite the combined exhaust gases and combustion air. The enclosure is insulated to retain the heat generated in the combustion operation. An outlet is provided from the enclosure so that any unburnt gases remaining from the exhaust gases can be collected and harmful substances removed to avoid any pollution of the atmosphere.
