ABSTRACT:
An indirect-fired, infrared drying oven for articles of manufacture which have been through a coating process. Tubular radiators are mounted within the enclosure to produce infrared radiation which impinges upon the coated articles. The tubular radiator operates at a sub-ambient interior pressure and is vented near the burner to directly inspirate fumes from the interior of the oven as they are given off by the drying articles. Temperatures in the radiator are sufficient to incinerate the fumes as they travel along the length of the tubular radiator. A heat exchanger is utilized near the exhaust end of the radiator to recover waste heat and return this heat to the oven enclosure, thus balancing air flow within the enclosure and maintaining a neutral pressure condition.
