摘要： The invention relates to a glass melting tank (1), comprising at least one front part (6) for introducing the charge material and at least one charging device. In order to achieve the aim of improving the charging technology via front parts (6) of glass tank furnaces to the effect that heat losses to the atmosphere and transport of dust into the upper furnace of the tank are reduced, and nevertheless the heating of the charge material is intensified, according to the invention the front part (6) a) has a length "LV" of at least 2,250 mm in the direction of the melting tank (1), and b) at a length "LG" of at least 1,200 mm is provided with an insulating roof (7), which has an end wall (8) towards the charging device, which, together with the roof (7), encloses a gas chamber (9) that is open toward the melting tank (1), c) wherein the so-called characteristic value "K" of 3.50 tonnes (t) per hour and per square metre of surface is not exceeded, said characteristic value being calculated from P/F, where P is the throughput per hour in tonnes (t) and F is the inner surface of the front part in m

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： A method of forming high strength glass fibers in a refractory lined glass melter is disclosed. The refractory lined melter is suited to the batch compositions disclosed for the formation high modulus, and high-strength glass fibers. The glass composition for use in the method of the present invention is up to about 70.5 Weight % SiO2, 24.5 weight % Al2O3, 22 weight % alkaline earth oxides and may include small amounts of alkali metal oxides and ZrO2. Oxide based refractories included alumina, chromic oxide, silica, alumina-silica, zircon, zirconia-alumina-silica and combinations thereof. By using oxide based refractory lined furnaces the cost of production of glass fibers is substantially reduced in comparison with the cost of fibers using a platinum lined melting furnace. Fibers formed by the present invention are also disclosed.

摘要： A glass melting furnace (10) that simultaneously preheats and removes volatile substances from glass making material being introduced into the furnace (10). The glass making material, consisting of cullet and scrap glass, is introduced on a shelf (68) located at a rear portion of the furnace (10). A vertically-oriented crown vent (34) is also located at the rear portion of the furnace (10). The shelf (68) is at such an elevation above the glass line (14) to allow sufficient time for the cullet and scrap glass to be heated by the exhaust gases exiting through the crown vent (34). The furnace burners (44) also oxidize the binder and other organic materials in the scrap glass. The furnace (10) also includes a crown vent support system that independently supports the refractory stack (74) such that the refractory stack (74) can be repaired or replaced while the furnace (10) is operating.
