Abstract
Some commercial broilers have a conveyor extending through the broiler from an entrance opening to an exit opening and have a plurality of burner housings, including end burner housings, arranged above the conveyor and spaced apart with respect to each other and particularly with respect to the entrance opening and the exit opening to leave gaps. To conserve heat, the passageway through the broiler above the conveyor is herein restricted by baffles including an entrance shield of heat-reflecting material formed as a channel frictionally fitting over the entrance burner housing and having a baffle sheet extending from the entrance burner housing through most of the gap toward the entrance opening. Also included is an exit shield of similar material formed as a similar channel fitting over the exit burner housing and having a baffle sheet extending from the exit burner housing through most of the gap toward the exit opening. Further, there is an intermediate shield including a horizontal sheet of similar material resting on adjacent burner housings and having a vertical sheet depending from said horizontal sheet. The entrance shield, the exit shield and the intermediate shield define the upper limits of the passageway through the burner and tend to reflect heat away from the entrance and exit openings and to limit air circulation within and through the passageway.
