摘要：将纯氧燃烧玻璃窑炉作为研究对象,使用火焰空间与池窑双向热耦合的方法建立数值模拟耦合模型。在此基础上对窑炉性能进行研究,以提高传热效率和延长使用寿命为目的,使用正交试验方法对氧化剂中氧气含量(A)、空气预热温度(B)、燃料质量流量(C),过剩氧气系数(D)、喷嘴距玻璃液面高度(E)、烟气出口面积(F)这6个因素进行优化。结果表明,所选因素的影响程度由高到低依次为:B>E>C>A>D>F,忽略次要因素D、F的影响,选取水平为优化工况进行模拟验证,与原工况相比,碹顶相对温差降低了18.8%,传热效率提高了7.7%,有较好的优化效果。
Taking the oxy-fuel combustion glass furnace as the research object,a numerical simulation coupling model is established using the method of two-way thermal coupling between the flame space and the pool space.On this basis,the performance of the furnace is studied with the aim of improving heat transfer efficiency and extending service life.The orthogonal experimental method is used to optimize six factors,including oxygen content in the oxidizer(A),air preheating temperature(B),fuel mass flow rate(C),excess oxygen coefficient(D),the height of the nozzle from the glass liquid surface(E),and flue gas outlet area(F).The results indicate that the degree of influence of the selected factors,from high to low,is as follows:B>E>C>A>D>F.Ignoring the influence of secondary factors D and A1B3C3E1F,level combinations are selected as the optimal operating conditions for simulation verification.Compared with the original operating conditions,the relative temperature difference at the crown has decreased by 18.8%,and the heat transfer efficiency has increased by 7.7%,showing a good optimization effect.
