Abstract
An oxidation oven with a heated chamber for treating fibers, the heated chamber having two opposing sides, each side with a plurality of gaps to allow the fibers to pass to and from the heated chamber. Embodiments of the invention provide capture ducts, which are configured to be under negative pressure, the capture ducts draw-in heated chamber air that would otherwise flow through the gaps. Embodiments of the invention provide supply ducts, which are configured to be under positive pressure and provide heated air near the gaps. Embodiments of the invention provide louvers positioned near the gaps, the louvers are configured to reduce the flow of heated chamber air that would otherwise pass through the gaps.
