卡脖宽度对玻璃熔窑能耗及运行质量影响的模拟
|
摘要
采用Glass Furnace Model软件,数值模拟分析了卡脖宽度对浮法玻璃熔窑能耗、玻璃液流动与温度分布的影响,以及熔窑熔化因子、澄清因子、均化因子等质量指标的变化规律。550t/d案例浮法熔窑模拟分析结果表明,卡脖由设计宽度4.0 m减小为2.5 m时,可提高熔化区、澄清区玻璃液温度10℃以上,实现熔窑单耗降低3%,熔化、澄清质量提高10%。因此,卡脖宽度的优化设计,是提高玻璃熔窑热效率、实现节能减排的有效手段。
The influence of waist width on the energy consumption, glass flow and temperature distribution of float glass furnace was simulated via a software named Glass Furnace Model. The melting index, fining index, mixing index were analyzed based on the simulated results. The simulated results of the sample float glass furnace with a capacity of 550 t/d show that the glass temperature in melter and finer is increased by 10 ℃, and the unit energy consumption is decreased by 3%, while the melting and fining performance of the furnace is increased by 10% with decreasing the furnace waist width from the designed value of 4.0 m to 2.5 m. The optimal design of waist width is an efficient way to improve the energy efficiency of glass furnace.
