砼储油罐空气隔热层的最佳厚度分析

Optimal Thickness Analysis of the Air Heat Insulation Layer Embedded in a Concrete Oil Tank

摘要: 根据封闭空气隔热层的传热机理,通过极值分析,推导出使垂直空气层保温效果最好的最佳隔热层厚度公式,为降低混凝土储油罐的罐壁温差、预防和控制裂缝,提供了一条经济有效的途径.

Abstract: Based on the heat-transfer mechanism of a sealed-in air heat insulation layer, an optimal thickness formula of the air layer is derived by the extremum analysis method. Calculating results show that this is an economic and effective method to reduce the temperature difference of the tank wall, and prevent and control cracks in the wall of a concrete oil tank.
