Abstract
A radiant wall drying oven that includes a first wall and a second wall situated in spaced apart relation to define an air conducting passageway. Heated air is supplied to contact the first wall, and a selected amount of heated air is allowed to pass through inlets into the air conducting passageway. Sliding dampers positioned at a predetermined site relative to the second wall control the amount of heated air contacting a portion of the second wall, and consequently regulate the amount of radiant heat emitted by that portion of the second wall.
