摘要： When waste glass that is highly contaminated with organic impurities is melted, these impurities cause the appearance of so-called 'black grains ' which cannot be eliminated in a subsequent refining process and which therefore impair the quality of the glass. According to the invention, gas nozzles (19) for introducing oxygen are arranged in the area of the feed opening (4) of a melting aggregate (2) which is thermally connected to a combustion chamber (3). The organic constituents are thus oxidised specifically and removed as waste gas (21). The invention enables even very highly contaminated waste glass, such as glass fibres, to be fed back into the production process.

摘要： A heated crucible apparatus (10) allows the adjustment of a thermal profile within a combustion chamber (12) surrounding the crucible (15) by introducing a sub-stoichiometric or a super-stoichiometric mixture of fuel and oxidant into the combustion chamber (12) and varying the oxidant flow for sub-stoichiometric or fuel flow for super-stoichiometric mixture downstream of the initial combustion to control the release of heat in defined areas within the combustion chamber (12). The apparatus includes an oxidant (54) and fuel (25) supply at the primary injection point (32) followed by secondary injection of the remaining oxidant supply at specific intervals to achieve the desired thermal profile. An oxidant preheating heat exchanger (51) and a cooling heat exchanger (49) for material exiting the crucible may be provided.

摘要： A method of heating a surface provides for a central fuel rich jet (40) having a peripheral shroud (41) of substantially stoichiometric combustion products and one or more fuel lean jets (30) each having a peripheral shroud (31) of substantially stoichiometric combustion products. The fuel lean jets (30) are placed around the periphery of the central fuel rich jet (40). The fuel lean jet or jets each having shrouds of substantially stoichiometric combustion products and a careful choice of relative velocities for each results in minimizing the mixing of the fuel rich and fuel lean jets until they are at or near the surface of the material to be melted. The placement of the fuel lean jet and fuel rich jets may be reversed in applications where an oxidizing atmosphere is required at the surface to be heated.

摘要： According to the present invention there is provided a refractory lined glass melter (10) for producing refined glass from raw glass-forming material (30) using at least one oxygen-fuel burner (34) recessed within a burner block (38) mounted in the roof (22) of the furnace (10) and a process of using the burner (34). The velocities of the gaseous fuel and of the oxygen from the oxygen-fuel burner (34) are controlled such that the velocities of the gaseous fuel and the oxygen are substantially equivalent to provide a generally laminar gaseous fuel and oxygen flow to combust proximate a top surface of the raw glass-forming material (30) and produce a flame which impinges the surface of the raw glass-forming material (30) and which has a middle portion of a columnar shape.

摘要： A self-cooled oxidant-fuel burner consisting novel fuel and oxidant nozzles and three compartment refractory burner block design is proposed. The new oxidant-fuel burner can fire in high-temperature (2200°F to 3000°F) and high-particulate (or high process volatiles/condensates) furnaces without over-heating or causing chemical corrosion damage to it's metallic burner nozzle and refractory burner block interior. Using various embodiments of nozzle and block shape, the burner can offer a traditional cylindrical flame or flat flame depending on the heating load requirements. The new features of this burner include unique fuel nozzle (16) design for the streamline mixing of fuel and oxidant streams, a controlled swirl (24) input to the oxidant flow for desired flame characteristics, a controlled expansion of flame envelope in the radial and axial dimensions, and efficient sweeping of burner block (4) interior surface using oxidant to provide convective cooling and prevent any build up of process particulates. In addition, a relatively thick wall metallic nozzle construction with heat conduction fins (18) enable efficient heat dissipation from the nozzle tip and providing a maintenance free burner operation.
摘要翻译：提出了一种自冷却的氧化剂 - 燃料燃烧器，其包括新型燃料和氧化剂喷嘴以及三室耐火燃烧器块设计。新型氧化剂燃料燃烧器可在高温（2200°F至3000°F）和高颗粒（或高过程挥发物/冷凝物）炉中燃烧，不会过热或对其金属燃烧器喷嘴和耐火材料造成化学腐蚀损伤燃烧器块内部。使用喷嘴和块形状的各种实施例，取决于加热负载要求，燃烧器可以提供传统的圆柱形火焰或扁平火焰。该燃烧器的新特点包括独特的燃料喷嘴（16）设计，用于燃料和氧化剂流的流线混合，用于期望火焰特性的受控漩涡（24）输入到氧化剂流，径向火焰包络的可控膨胀和轴向尺寸以及使用氧化剂对燃烧器块（4）内表面进行有效清扫以提供对流冷却并防止任何过程微粒的积聚。此外，具有导热翅片（18）的相对较厚的金属喷嘴结构能够实现喷嘴头的有效散热并提供免维护的燃烧器操作。
