ABSTRACT:
A hood is assembled of modules including a central make-up air plenum module directly over the heating stations of a conveyorized double-deck oven, an exhaust plenum module atop the makeup air plenum and downwardly-opening end modules overhang the conveyor end portions extending outside the sides of the oven heating chambers. The end modules have make-up air directors aiming make-up air upward along the undersides of removable panels having slots therein to accelerate exhaust flow into a chamber below filters to effectively remove fumes from the areas above the conveyor ends. The overhanging end modules also have partitions therein cooperating with the walls of the overhang portions to provide ducts at the front of the overhang portions to capture fumes from the area above the front of the conveyor ends. Air flow guides around the extending portions of the conveyors assist. A makeup air diverter and diffuser are provided, discharging air from the front of the makeup air plenum down the front of the ovens to cool the front exterior surfaces.
