摘　　要：玻璃窑炉应用梯度增氧助燃后,燃烧产物的温度、碱蒸气和水蒸气含量以及NO_x浓度等均发生了变化,导致熔化部和冷却部各部位的作业环境和耐火材料使用过程中损毁的原因也发生了改变,本课题在合理选取熔化部和冷却部各部位耐火材料材质的基础上,对熔化部和冷却部窑池结构以及上部空间结构进行了改进设计,以适应梯度增氧助燃上、中、下部分层燃烧结构,达到了降低整个窑炉NO_x排放浓度的目的,同时也提高了熔化部和冷却部整体结构的安全稳定性,降低了窑炉的能耗,延长了窑炉的使用寿命。After gradient increase combustion oxygen, the temperature、basic vapor and water vapor and NOX content of combustion products that are produced by glass furnace are varied, so that the work environment and damage reason of melter end and working end refractory are varied. On the basis of choice reasonable refractory, This article improve structural design of tanks and superstructure for melter end and working end, In order to adapt to up、centre and below zone of combustion for gradient increase combustion oxygen and reduce NOX emission concentration. The security and stability of melter end and working end are enhanced 'saving energy consume of glass furnace and extending life of glass furnace .
