基于架空蒸汽管道输送高温蒸汽时产生的热损失，建立了蒸汽管道的物理模型和数学模型，对比了目前架空管道常用的三种保温材料。研究结果表明，纳米气凝胶复合反射式保温结构应用效果最好。模拟了不同的蒸汽温度、管径、绝热层厚度下的管道及保温层的温度场分布。模拟结果表明，管径对架空蒸汽管道热损失的影响最大，当管径从126 mm 增加到132 mm 时，热损失增加10.70262 kJ/(h·m)。

Based on the heat loss occurred when a pipeline to transport high-temperature steam vapor overhead,it is established physical and mathematical models of steam pipeline,and compared to the three commonly used insulation materials of overhead pipeline.Research results showed that the application results of nano airgel composite reflective insulation was the best.The different steam temperatures of the temperature field of pipeline and insulation layer in,different diameter and different insulation thickness distribution were simulated.By analyzing the temperature field indicated that changing the diameter effected the heat loss of overhead vapor line greatly.When the diameter changed from 126 mm to 132 mm unit length, the heat loss increased 10.702 62 kJ/(h ·m).
