列表法计算架空蒸汽管道保温层经济厚度

摘要

通过计算保温层的各项费用,并对其进行列表分析,找出了最小总费用所对应的保温层厚度,从而得到了保温层的经济厚度,达到了节约能源的目的.算例分析结果表明,该方法能够科学地反映保温层厚度与年总费用的关系.该方法简单易懂,可大大提高设计效率和设计质量.%Through the calculation of all the expenses for insulation layer and the list analysis, the thickness of insulation layer corresponding to the minimum total cost was found. Therefore the economic thickness was obtained to achieve the purpose of saving energy. The calculation results showed that the new method can scientifically reflect the relationship between the annual total cost and the thickness of insulation layer. And the method is straightforward and improve the design efficiency and quality greatly.
