【摘要】 采用Glass Furnace Model专用熔窑数值模拟软件,对国内某一600t/d浮法熔窑,建立燃烧空间与玻璃池窑耦合的数值模型,研究了电助熔引入及电极棒排布位置对熔窑内燃烧空间和玻璃池窑温度场、流动场的影响,并通过玻璃熔化质量因子分析了不同工艺条件下玻璃液熔化质量。模拟结果表明:在玻璃熔窑内引入电助熔,可以减少燃料使用量,降低燃烧空间和玻璃液表面温度。而玻璃液平均温度提高,玻璃液流动速度加快,提高了玻璃液平均熔化质量,电极棒布置在原料区末端与热点之间时,电助熔效果最佳。更多还原

【Abstract】 The combustion model and glass model were built and coupled to simulate the glass melting process at a 600 t/d float glass furnace.The effect of electrical boosting and electrode position on the glass melting process was investigated with the temperature and velocity fields.And the glass quality index was used to evaluate the glass melting quality at varied conditions.The results show that the fuel consumption was reduced with the electrical boosting,resulting in the lower temperature in combustion space and glass surface.However,the mean temperature and velocity of glass was increased,which improved the glass melting quality.The optimal electrical boosting was achieved when the electrode was set between the batch zone and hot spot.更多还原
