Abstract
A glass manufacturing apparatus can include a conduit connected to a delivery vessel and an inlet of a forming vessel. The conduit includes a closed sidewall surrounding a channel extending in a flow direction of the conduit. The closed sidewall is continuous from the delivery vessel to the inlet of the forming vessel to define a closed atmosphere from the delivery vessel, through the conduit, and through the inlet of the forming vessel. The glass manufacturing apparatus can include a heating enclosure including a heating wall and a first heating element. The heating wall surrounds a chamber within which the conduit extends. The first heating element is positioned within the chamber between the heating wall and the conduit to increase a temperature within the channel. Methods for manufacturing a glass ribbon with a glass manufacturing apparatus are provided.
