摘要
通过建立玻璃池窑的零维传热模型和配合料的一维非稳态数学模型及其数值模拟,定量揭示了配合料的导热系数,火焰空间燃烧产物,火焰黑度对配合料传热效果的影响,表明了配合料粒化或压实后导热系数由0.2w/m·℃增大到0.4w/m·℃时,其节能14％以上,火焰黑度由0.2～0.85时,火焰空间传给配合料的热流量增加3～5倍。
By estabilishing the O-D mathematical model of heat transfer in glass furnace and 1-D mathematical model unsteady heat transfer in batch and the numerical simulation, the influence of the thermal conductivity of the batch and the combusion products and the flame emissivity has been shown in heat transfer. It shows that energy is saved to 14 percent as batch conductivity of partical and of pressure increases from 0.2(w/m·℃) to 0.4 (w/m·℃), and that heat flux for flame transfering to the batch increases 2-4 twice as the flame emissivity increases from 0.2 to 0.85.
