摘　　要：利用火用经济学的基本原理 ,对供热蒸汽管道内蒸汽的输送过程进行了分析 ,得到了供热蒸汽管道的年总费用方程 ,该方程可用于分析供热蒸汽管道管径和保温层厚度等因素对年总费用的影响 ;同时 ,提出了供热蒸汽管道及其保温层的同步设计法 ,从降低输送蒸汽费用的角度出发 ,得到了最佳管径和最佳保温层厚度的计算公式 ,其结果可供工程设计参考。Based on the principle of exergy economy, the equation for annual total cost of heating steam pipe is derived by analyzing the process of carrying steam, which can be used to discuss the effects of pipe diameter, insulation thickness on the annual total cost. Synchro design method for heating steam pipeline and its insulation is presented. From the point of reducing the annual total cost of carrying steam, the calculating formula of the optimum diameter of heating steam pipe and insulation thickness are obtained.
