Abstract
The utility model discloses a melting furnace for melting glass, which includes a crown and two pairs of side walls all provided with inner surfaces made of refractory materials, wherein at least one burner opening is arranged in the side walls, and the burner openings and the side walls are downwards arranged and form acute angles; and a burner perpendicular to the direction of the plane where the burner opening is arranged is arranged on the burner opening. Therefore, flame generated by the burner produces certain heat convection to glass metal to be melted, as the high-temperature region of flame is contacted with or near to the glass metal, the melting of glass metal can absorb radiation heating of flame and convection heating brought by flame, thereby greatly improving the heat efficiency and further improving the capability of saving energy; and besides, as the high-temperature region of flame is far from the crown, the difficult problems that the pure-oxygen flame seriously corrodes the crown, and the refractory materials are difficult to choose are solved.
Description
Technical field
The utility model relates to the glassmaking field, especially a kind of melting furnaces that are used for the glass melting operation.
Background technology
In the manufacturing processed of glasswork, through making admixtion at high temperature be fused into high-quality glass metal, for following process provides condition, this realization is expected from cooperation and the structure with certain function of glass metal is called as " melting furnaces ".Conventional melting furnaces have a firing system, and this firing system comprises a large amount of burners, and this burner is that the fusing of admixtion provides heat.The arrangement form of normal burner in the melting furnaces has been shown in Fig. 2; The big arch of melting furnaces, both sides sidewall and front and rear wall constitute by refractory materials; Run through the both sides sidewall a large amount of burner ports is arranged; Burner port meets at right angles with respect to sidewall and is drilled to, and burner port is suitable for ccontaining burner, the burner port 0.5-3m of being separated by each other.Along with the continuous use of pure oxygen technology, its advantage is more and more admitted by people.Pure oxygen burning is meant fuel and 90~100% pure oxygen by predetermined combustion than mixing, with than air-breathing accurate way incendiary technology more.Exist because of no nitrogen in the pure oxygen burning process, thereby can improve temperature of combustion and flame propagation velocity, capacity usage ratio improves, and a large amount of minimizing of waste gas causes the thermosteresis minimizing in addition, thereby pure oxygen is combustion-supporting than air-breathing fuel saving.According to Theoretical Calculation, if reach same temperature of combustion, pure oxygen is combustion-supporting than air-breathing fuel saving more than 50%.And practical application also proves, compare with the heat exchange type kiln, but fuel saving 35~60%.The hear rate of founding every kilogram of glass like present unit kiln is 2500 kilocalories to 3000 kilocalories; After using pure oxygen; To reduce to below 1600 kilocalories, and reduce discharge amount of exhaust gas 70~80%, pure oxygen burning can reduce the discharging of flue dust, NOx and SOx; Thereby the minimizing topsoil, be reduce to pollute and discharge of poisonous waste one of best approach of vitality and cost benefit arranged most.Because pure oxygen burning has improved the flame temperature of metal level, thereby can improve tank furnace melting rate about 20%, the physical imperfection of glass reduces simultaneously; The glass metal quality improves; So burner adopts oxygen-fired burners, level is inserted the side wall burning, utilizes radiation that glass is heated.Therefore, melting furnaces inside is a large amount of burner, arm, accessory and valve and common collaborative works of burner.The drawback that such melting furnaces exist is that the oxygen-fired burners horizontal direction is placed; There is certain distance the flame high-temperature zone apart from glass metal, can only offer the certain radiation heating of glass melting, has limited the melting rate of glass metal in the melting furnaces; Pure oxygen flame becomes 90 ° of burnings with side wall in addition; Flame profile receives the interior airflow influence of tank furnace that distortion is significantly arranged, and flame high-temperature zone and big arch close together are more serious to the erosion of big arch.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of melting furnaces that are used for the glass melting operation,
Further improved thermo-efficiency, also reduced of the corrosion of pure oxygen flame simultaneously big arch.
For achieving the above object, the technical scheme that the utility model adopted is:
Include internal surface by big arch and two oppose side walls that refractory materials constitutes, on sidewall, be provided with at least one burner port, described burner port and sidewall are the acute angle setting downwards; Be provided with burner on perpendicular to its place planar direction on the described burner port; The flame that burner produced like this to the glass metal that will melt certain thermal convection is arranged because the high-temperature zone of flame contacts or close together with glass metal, heat so the fusing of glass metal can not only absorb flame radiation; Also absorb the convective heating that flame brings; Improved thermo-efficiency greatly, the ability of save energy had further raising, in addition since the high-temperature zone of flame away from big arch; Solved pure oxygen flame to big arch seriously corroded, the difficult problem of the bad selection of refractory materials;
Described burner port is arranged on the relative sidewall and lateral alignment, is applicable to the melting furnaces of relative broad, because the burner positioned opposite, uniformity of temperature profile in the melting furnaces can provide more uniform heat distribution to the glass metal fusing;
Described burner port is arranged on the relative sidewall and is laterally staggered; Be applicable to the melting furnaces of relative narrower, because burner is interval-staggered, the burner spacing strengthens; Reduced the consumption of burner and matching component thereof; Thereby reduced cost, avoided flame in melting furnaces, to collide in addition and dashed, big arch is corroded;
Described burner port is arranged on the relative sidewall and lateral alignment and horizontal staggered having concurrently, can make raw material fusing relative equilibrium, guarantees the stable control that is of consistence that both sides feed intake and stockline.
