Abstract
For high temperature steam vapor transport in the buried pipeline causes heat loss and leads to energy waste problems,several factors affecting heat loss were analyzed.Steam pipeline of physical model and mathematical model was established to simulate the different steam temperatures,different buried depth and temperature distribution under different insulation thickness.And temperature distribution pipeline and the surrounding soil were calculated and analyzed under different conditions.The results show that the heat loss of buried steam lines with the steam temperature,buried depth,changed the thickness of the insulating thickness changes,and the biggest affect of the heat loss was the insulation thickness.When the insulation thickness was from 40 mm to 80 mm,the heat loss per unit length declined 1 10.591 W/m,and the thermal effect was smaller and smaller .关键词
