投料口/烟道口位置对全氧顶烧窑炉温度场和流场影响的数值模拟
Numerical Simulation of Charging Port/Flue Outlet Position Effects on Temperature and Flow Fields in Full-oxygen Top-fired Furnaces
摘要
Abstract
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.关键词
