Abstract
The utility model discloses a melting furnace for glass melting operation, which comprises a main crown with an inner surface made of refractory materials and two pairs of lateral walls. At least a burner opening is formed on each lateral wall is in sharp angle arrangement with the lateral walls downwards; a burner is arranged in the direction of the burner opening vertical to a plane where the burner opening is positioned, so that flame generated by the burner has a certain heat convection to glass liquid to be melted; because the high temperature zone of the flame is in contact with or is close to the glass liquid, the glass liquid can not only absorb the radiation heating of the flame during the melting process, but also absorb the convection heating caused by the flame, so as to greatly improve the heat efficiency and further improve the capacity of energy conservation; in addition, because the high temperature zone of the flame is far away form the main crown, the difficult problems that the corrosion caused by the pure oxygen flame to the main crown is serious and the refractory materials are difficult to select 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, by 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 provides heat for the fusing of admixtion.Figure 2 illustrates the arrangement form of normal burner in the melting furnaces, 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, 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 as present unit kiln is 2500 kilocalories to 3000 kilocalories, after using pure oxygen, to reduce to below 1600 kilocalories, 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, 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 is subjected to 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, has further improved thermo-efficiency, has also reduced the corrosion of pure oxygen flame to big arch simultaneously.
For achieving the above object, the technical scheme that the utility model adopted is:
Include big arch and two oppose side walls that internal surface is made of refractory materials, 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 has certain thermal convection to the glass metal that will melt like this, because the high-temperature zone of flame contacts or close together with glass metal, so the fusing of glass metal can not only absorb the flame radiation heating, also absorb the convective heating that flame brings, improved thermo-efficiency greatly, ability to save energy has 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 upper punch in addition, big arch is corroded;
Described burner port is arranged on the relative sidewall and lateral alignment and laterally 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.
