Glass manufacturing apparatus and methods of manufacturing glass

Abstract

Glass manufacturing apparatus comprise a forming body configured to draw a glass forming ribbon and positioned within an enclosure. Glass manufacturing apparatus comprise a first diffuser comprising a first inlet comprising a first inlet cross-sectional area and a first outlet comprising a first outlet cross-sectional area. The first outlet cross-sectional area is greater than the first inlet cross-sectional area. The first outlet is positioned within the enclosure. Methods of manufacturing a glass ribbon comprise flowing a glass-forming ribbon. Methods comprise flowing a first gas through the first inlet of a first diffuser at a first average inlet velocity. Methods comprise flowing the first gas from the first diffuser through a first outlet of the first diffuser at a first average outlet velocity. The first average inlet velocity is greater than the first average outer velocity.
