摘　　要： 以实体模型和计算机数值模拟对蒸汽管道保温状况进行实验,分析保温层的材料、厚度、结构,保温结构外表面黑度,环境温度和环境风速对保温效果的影响。对蒸汽管道保温结构的优化设计和施工提供了有针对性和指导性的建议。研究证明当采用优质硅酸铝陶瓷纤维保温时,保温层厚度不低于180mm时可满足φ530mm×20mm长距离供汽管道保温优化的要求。在保温层中加铝箔层可使散热量减少5%左右。这一研究成果已应用于中国石油化工股份有限公司广州分公司热电站向乙烯供汽管道保温工程,得到了充分验证,取得良好的经济效益。 Steam pipeline insulation has been experimented with the model and computer data simulation. The material, thickness and structure of the insulating layer, surface blackness of the insulating structure together with the influence of environmental temperature and air speed on the insulation effect have been analyzed. Suggestions for optimal design and construction of steam pipeline insulation have been proposed. The research result shows that when high quality aluminum silicate ceramic fiber was used as the insulation material and its thickness reached 180 mm, optimal insulation requirement of 530 mm x 20 mm long distance steam pipeline has been met. By adding a-luminum foil into the insulation layer, heat dispersion has been reduced about 5% . The research result has been applied in the steam pipeline insulation engineering and good economic benefits have been obtained.
