The invention relates to methods and to devices for a melting furnace, or for the conveying ones of the product to be melted, having an infinite life (furnace campaign). The same is achieved by means of the continuous/periodic, e.g. cyclic, exchange, in the optimum case, of all of the components surrounding the furnace interior/melting space, or surrounding the conveying lines, in that the components can be arranged/placed next to each other in a modular manner and that said components move in a certain direction while new individual parts are added at one of the free ends of the respective assembly and while worn/used individual parts are removed at the other free end of the respective assembly. For this purpose the individual components are held and/or moved by suitable receptacles, wherein the furnace interior/melting chamber remains stationary.

Methods of processing molten material comprising the step (I) of flowing molten material through an interior of a conduit from a first station to a second station of a glass manufacturing apparatus and the step (II) of cooling the molten material within the interior of the conduit by passing a cooling fluid along an exterior of the conduit. The method further includes the step (III) of directing a travel path of the cooling fluid toward a vertical plane passing through the conduit. In further examples, a glass manufacturing apparatus comprises a first station, a second station, and a conduit configured to provide a travel path for molten material traveling from the first station to the second station. The glass manufacturing apparatus further comprises at least one baffle configured to direct a travel path of cooling fluid toward a vertical plane passing through the conduit.

Primary inorganic feedstock material is introduced into the melting region of an SCM melter. The material is heated with a burner to form a turbulent melt matrix. The burner exit is disposed below the top surface of the turbulent melt matrix. A mixture of secondary inorganic material and organic material is introduced into the melting region below the top surface of the turbulent melt mixture. The mixture is heated with the burner to incorporate the secondary inorganic material into the turbulent melt matrix and combust at least some of the organic material to produce heat.

A glass melting plant having a melting tank having end-fired heating, the melting tank having a feeding material inlet, an outlet for removing the molten glass, and a melt surface of at least 40 m.sup.2. At least one doghouse is laterally situated and is connected to the melting tank inlet for feeding material input. The doghouse has side walls that, together with the melting tank inlet, limit a feeding surface area, and has a feeding device. The doghouse has a roof with an end wall oriented toward the feeding device, which end wall encloses, with the roof, a gas compartment open toward the melting tank. To increase the specific melting performance with at least equal glass quality, the feeding surface of the doghouse is at least 8 m.sup.2 and, given a melt surface of at least 115 m.sup.2, is at least 7% of the melting tank melt surface.

A glass furnace includes a furnace chamber for containing glass melt and a conveyor for receiving glass batch material and feeding the glass batch material to the furnace chamber. A dam wall is disposed with respect to the conveyor such that batch material from the conveyor must flow upward over the dam wall before entering the furnace chamber. The top of the dam wall may be below the level of the melt pool in the furnace chamber.
