摘要
根据热水直埋供热管道的传热原理,对大管径热水直埋供热管道的保温层厚度计算方法进行了探讨。提出保温层厚度的计算应采用控制热水直埋供热管道外表面温度和满足热网输送效率的综合计算方法。
According to the heat transfer principle of directly buried hot-water heat-supply pipeline, the calculation method of insulating layer thickness of directly buried hot-water heat-supply pipeline is discussed. It is put forward that a comprehensive calculation method should control the external surface temperature of directly buried hot-water heat-supply pipeline and meet the transmission efficiency of heatsupply network.
