    摘要： A method for controlling a plant for melting a raw-material composition, suitable for obtaining mineral wool, cullet, textile glass yarns and/or flat glass or container glassware, which includes a melting chamber suitable for melting the composition, wherein the composition includes at least one wet mixture of mineral wool and/or biomass, and the method includes controlling at least one physical variable that has an impact on the output of the melting chamber, the controlling being carried out as a function of the moisture content of the composition and/or of the wet mixture, as measured before introduction of the composition and/or of the wet mixture into the melting chamber.

    摘要： A method for recycling glass mat waste, wound rovings, and other products includes providing a source of glass mat, or a plurality of rovings, for example on a roll, and routing the glass mat or rovings into a submerged combustion melter. An unwind system and a pair of powered nip rolls, powered conveyors, or other arrangement may work in combination to provide a substantially consistent rate of material into the melter. The melter may operate under less than atmospheric pressure to avoid fumes escaping the melter. A slot in the melter allows ingress of the glass mat or rovings into the melter, and a glass mat former such as a folder may be used to ensure that the mat fits through the slot. Alternatively, the glass mat may be cut by a slitter prior to entering the slot.

    摘要： Fluid-cooled impingement burners have an external conduit and a first internal conduit substantially concentric therewith forming a first annulus for passing a cooling fluid. A second internal conduit forms a second annulus between the first and second internal conduits. A burner tip body defined by an inner wall, an outer wall, and a half-toroid crown, the inner wall connected to the first internal conduit, the outer wall connected to the external conduit, the inner wall defining a central flow passage for a combustible mixture. A third internal conduit generally concentric with the external conduit and positioned between the external and the first internal conduits, a first end of the third internal conduit extending into but not connecting with the half-toroid crown. A first end of the second internal conduit recessed is below the half-toroid crown, and the position of the first ends of the second and third internal conduits delay combustion of fuel with the oxidant.

    摘要： The invention relates to a material feeding system (1) for a melter comprising: (i) a substantially horizontal feeding barrel (5) designed to feed solid material through the melter wall (9) into the melt (11) contained in the said melter, and arranged below the level (13) of the melt (11) contained in the melter (30), (ii) said feeding barrel (5) comprising a material input opening (15) and material output opening (17), the material output opening (17) leading into the melt (11) contained in the melter (30), said feeding barrel (5) comprising an internal feeder (20) designed to push solid material (7) loaded through the material input opening (15), in the direction of the longitudinal barrel axis (6) toward the material output opening (17), the end of the internal feeder (20) on the material output side extending at a minimum at a distance from the internal melter surface (19) of two (2) to ten (10) times the diameter of the feeding barrel (5), preferably three (3) to eight (8) times the diameter of the feeding barrel, more preferably three (3) to six (6) times the diameter of the feeding barrel or three (3) to five (5) times the diameter of the feeding barrel (5). The invention further covers a submerged combustion melter equipped with above material feeding system and a process for feeding material into a melter.

    摘要： Submerged combustion glass manufacturing systems include a melter having a floor, a roof, a wall structure connecting the floor and roof, and an exhaust passage through the roof. One or more submerged combustion burners are mounted in the floor and/or wall structure discharging combustion products under a level of material being melted in the melter and create turbulent conditions in the material. The melter exhausts through an exhaust structure connecting the exhaust passage with an exhaust stack. The exhaust structure includes a barrier defining an exhaust chamber having an interior surface, the exhaust chamber having a cross-sectional area greater than that of the exhaust stack but less than the melter. The barrier maintains temperature and pressure in the exhaust structure at values sufficient to substantially prevent condensation of exhaust material on the interior surface.
