Abstract: The invention relates to a process for preparing a mineral melt in a cupola furnace that comprises, in the hot zone where the melt collects, a plurality of ceramic support bodies, with at least one plasma torch providing heat energy to the furnace. The combination of the plasma torch and ceramic support bodies reduces or substantially eliminates the need for coke to be used in the furnace. This reduces the formation of environmentally harmful gasses, such as CO and CO2, in the off-gas of the furnace.

Abstract: A method of producing glass includes drawing unrefined foamy molten glass (18) from a glass melt (16) held in a submerged combustion melter (10) and introducing the unrefined foamy molten glass (18) into a stilling chamber (82) of a stilling tank (70). An intermediate pool of molten glass (84) is held within the stilling chamber (82) of the stilling tank (70) and is heated therein by one or more non-submerged burners (90), Molten glass flows from the intermediate pool of molten glass (84) to a transfer pool of molten glass (114) held in a spout chamber (112) of a feeding spout (72) that is appended to the stilling tank (70), A molten glass feed (22) can be drawn from the transfer pool of molten glass (114) and delivered from the feeding spout (72) at a controlled rate.

Abstract: A cooling panel (12, 212, 312, 412) for a melter (10) and method for fabricating the cooling panel (12, 212, 312, 412) are disclosed. In particular, the cooling panel (12, 212, 312, 412) can include first (20, 120, 220, 420) and second (22, 122, 222, 422) outer walls and a plurality of side walls (34, 36, 38, 40, 134, 136, 138, 140, 334, 336, 338, 340, 434, 436, 438, 440) coupled to the outer walls that define an interior space (62, 462). A plurality of baffles (24, 424) is disposed in the interior space (62, 462), where projections (48, 52) in the baffles (24, 424) fit into respective openings (28, 44) in the outer walls (20, 22, 120, 122, 220, 222, 420, 422) and can be connected from outside the cooling panel (12, 212, 312, 412). The cooling panel (12, 212, 312, 412) can be formed by way of welding and/or additive manufacturing, as discussed herein.

Abstract: In a process for manufacturing glass, a mixture of solid glass-forming materials (18) may be melted by application of heat from one or more submerged combustion burners (34) to produce a volume of unrefined molten glass comprising, by volume, 20% to 40% gas bubbles. A refining agent may be introduced into the unrefined molten glass to promote gas bubble removal from the molten glass. The unrefined molten glass including the refining agent may be heated at a temperature in the range of 1200°C to 1500°C to produce a volume of refined molten glass. The refined molten glass may comprise, by volume, fewer gas bubbles than the unrefined molten glass. A colorant material may be introduced into the.refined molten glass to produce a volume of molten glass having a final desired color.

Abstract: The invention concerns a process for operating a fired furnace (1) which is heated using a fuel gas stream and forming a combustion product stream, wherein heat of at least part of the combustion product stream is used in forming a steam stream. It is provided that at least a part of the steam stream is subjected to a high-temperature electrolysis (2) to form a hydrogen-containing and an oxygen-containing material stream, and that at least a part of the hydrogen-containing material stream is used as the fuel gas stream. A corresponding arrangement (100, 200, 300) is also the subject of the invention.
