【摘要】 全氧燃烧熔窑可节约燃料,减少NOX排放,降低对环境的污染,提高玻璃质量,提高火焰温度、熔窑熔化能力及熔窑产量,适当降低熔窑建设费用,提高熔窑使用寿命。优质浮法玻璃和高附加值特种玻璃也要求采用更为先进的燃烧工艺和玻璃熔制工艺。分析了全氧窑内大量碱蒸气和水蒸气的增加对胸墙、池壁、大碹等关键部位耐火材料的侵蚀及全氧熔窑耐火材料选材,对600吨/日浮法玻璃熔窑耐火材料使用进行对比分析,并对全氧玻璃熔窑耐火材料现状及前景进行展望。更多还原

【Abstract】 Oxy-fuel combustion furnaces have popular industrial applications because of their important advantages which would save lots of fuel,decrease the letting of NOX,reduce the pollution,improve the quality of glass,increase the temperature of the flame,melting ability and output of the furnace,duly reduce the cost to build a furnace and prolong the life of it.They are though to be the promising candidates for the production of high quality float glass and special glass with high added value which require advanced combustion and melting technology.In this paper,we analyzed the effects of lots of alkali vapor and the increasing of water vapor in oxy-fuel combustion glass melting furnace on the corrosion of the key parts of refractory materials such as breast wall,pool wall and crown.The selection of the refractory materials in oxy-fuel furnace was also discussed.In addition,the applications of refractory materials in 600t/d float glass melting furnace were analyzed.At last,the prospective of refractory materials in oxy-fuel combustion glass melting furnaces was performed.更多还原
