摘　　要：采用基于k-ε湍流模型、涡-耗散化学反应模型、P1辐射传热模型的数值模拟方法,研究了玻璃熔窑在全氧燃烧条件下烟气出口位置对窑内压力场和火焰空间的影响规律。研究结果表明,烟气出口位置的改变造成玻璃熔窑内压力场的变化,随着烟气出口的前移,整体的窑压平均值逐渐下降,尾气温度先升高后降低。The effect rules of flue gas outlet position in oxyfuel combustion furnace on furnace pressure field and flame space were studied with numerical simulation of k-εturbulent model,vortex-dissipation chemical reaction model and P1 radiant heat transfer model.Results show that the position change of flue gas exit will result in change of pressure field in glass furnace and the average pressure gradually reduce with the forward drift of the flue gas exit,therefore the temperature of tail gas shows increasing before decreasing.
