ABSTRACT:
An oven system for curing coated product is provided, where the oven line has at least one oven zone, with an entrance end, and a port through which coated product enters into the oven line. Means are provided for capturing substantially all of the indraft air, at least at the entrance end of the oven, near the port, and balance fan means are provided for circulating that indraft air at least in a first volume to a heat exchanger, and then back to the oven line. Solvent-rich air within the oven is withdrawn by an exhaust fan, and is delivered to an afterburner whose principal source of fuel is the volatile solvent which comes off the coated product within the oven as it is curing. A snout is provided, extending away from the entrance end of the oven in a direction towards the flow of coated product into the oven, and the snout has at least one hollow duct which is positioned near the flow path for the coated product, usually over the flow path. The hollow duct receives at least a portion of the heated indraft air which is being returned to the oven line, and that heated air passes through the snout duct and into the oven. The heated duct functions as a radiant heater, by which the coated product may be heated without heating the coating material on it. Some heated air may be bled from the end of the heated duct furthest from the entrance port to the oven, so as to slightly preheat the indraft air as it travels towards and into the oven.
