Abstract: A glass manufacturing apparatus includes a delivery tube terminating at a lower end in a delivery slot. A stream of molten material is delivered along a travel plane in a travel direction. A first plate is positioned adjacent the lower end of the delivery tube on a first side of the travel plane. The first plate includes a first edge extending adjacent the travel plane and a first thermal expansion slot extending from the first edge to a first interior. A second plate is positioned adjacent the lower end of the delivery tube on a second side of the travel plane. The second plate includes a second edge extending adjacent the travel plane and a second thermal expansion slot extending from the second edge to a second interior. The second edge is spaced apart from the first edge to define a delivery opening through which the delivery tube extends.

Abstract: A method of melting glass and glass-ceramics that includes the steps: conveying a batch of raw materials into a submerged combustion melting apparatus, the melting apparatus having liquid-cooled walls and a floor; directing a flame into the batch of raw materials and the melted batch with sufficient energy to form the raw materials into the melted batch; and heating a delivery orifice assembly in the floor of the submerged melting apparatus to convey the melted batch through the orifice assembly into a containment vessel. The melted batch has a glass or glass-ceramic composition that is substantially reactive to a refractory material comprising one or more of silica, zirconia, alumina, platinum and platinum alloys.

Abstract: In embodiments, a melter for melting glass may include an inlet wall, an outlet wall opposite the inlet wall, and sidewalls extending from the inlet wall to the outlet wall. The inlet wall, outlet wall, and sidewalls define a glass melting space enclosed by a floor and a top. In embodiments, the inlet wall may comprise a glass contact wall comprising a glass contact surface facing the glass melting space. A superstructure of the inlet wall comprises a jack arch positioned over the glass contact wall and at least a portion of the glass melting space. A plane of an interior face of the jack arch and a plane of the glass contact surface are off-set in a horizontal direction. A vertical distance from the floor to an underside of the jack arch is less than a vertical distance from the floor to an underside of the top.
