Abstract
The specification discloses a curing oven (10) and a control system (120) therefor. The oven (10) includes a heat exchanger (70) which preheats process air from the work chamber (36) before thermal oxidation. A separate recirculating fan (78), mixing box (84), and set of motorized dampers (92, 94) are provided for each zone (40, 42) of the work chamber (36) for controlling mixture of hot and cold air and delivery thereof to the work chamber for better temperature control. The motorized dampers (92, 94) are preferably controlled by microprocessors (124) responsive to temperature sensors (126, 128) located in the work chamber (36). Discharge of the exhaust fan (76) is adjusted by a motorized damper (96) through a controller (136) responsive to a pressure sensor (138) inside the oven (10).
