Numerical Simulation of Charging Port/Flue Outlet Position Effects on Temperature and Flow Fields in Full-oxygen Top-fired Furnaces
推动玻璃熔窑低碳制造于实现碳达峰、碳中和国家战略目标意义重大.全氧燃烧技术热效率高,其中顶烧方式因通过垂直定向直接加热,使火焰传热效率大幅提高,原料熔化速率加快,被广泛用于玻纤窑炉生产.本研究采用数值模拟方法研究了投料口和烟道出口不同位置对玻璃纤维窑炉温度场、流场及传热效率的影响,结果表明,采用窑头进料相比于侧边进料,玻璃液平均温度升高1.8℃,配合料的熔融加快,料层面积减小1.2 m2,玻璃液最小停留时间延长;基于窑头进料,采用双侧边烟气出口,烟气出口的平均温度最低,烟气在火焰空间内平均停留时间最长,烟气出口带走的热量最低为2917.8 kW,燃烧空间平均温度提升了4~7℃,传热效率最高为51.2%.合理布局投料口和烟道出口能显著改善窑炉内环境,减少能耗,增强玻璃纤维生产的稳定性和经济性.
Promoting low-carbon glass furnace manufacturing is crucial for achieving China's carbon peak and neutrality strategic goals.Oxy-fuel combustion technology offers a high thermal efficiency,particularly the top-fired configuration which enhances heat transfer efficiency through vertical directional heating,accelerates raw material melting rates,and is widely adopted in fiberglass furnace production.Numerical simulations were employed to investigate the effects of different feeder and flue outlet positions on the temperature distribution,flow patterns,and heat transfer efficiency in fiberglass furnaces.Results demonstrate that head charging,compared to side charging,increases average glass melt temperature by 1.8℃,accelerates batch melting,reduces batch coverage area by 1.2 m2,and extends minimum residence time.Combining head charging with bilateral flue outlets yields the lowest average exhaust temperature,maximum flue gas residence time,minimal heat loss(2917.8 kW),4-7℃ higher combustion space temperature,and peak heat transfer efficiency of 51.2%.The optimal arrangement of feeders and flue outlets significantly improves furnace environment,reduces energy consumption(by 6%-8%),and enhances both production stability and economic benefits in fiberglass manufacturing.
