摘　　要：根据水力计算选择的供热管道管径通常是一个范围值,为进一步优化供热管道管径配置,可以从技术经济的角度进行深入研究和分析。研究表明:预制直埋供热管道初投资成本随着管径的增大而逐步变大;而年运行费用随着管径的增大而逐步变小,故合理的预制直埋供热管道选型是保证总费用最低。文章以某热电厂给周边城市供热设计为例,分析预制直埋供热管道优化配置,从财务分析的角度提出年均总费用的概念,介绍各个参数的计算方法。结果表明,利率取8%时,计算可得年均总费用最小对应管径为φ1120*16。The diameter of heating pipeline chosen according to the hydraulic calculation is usually a range value.The results show that the initial investment cost of prefabricated direct-buried heating pipeline increases with the increase of pipe diameter.The annual operating cost decreases gradually with the increase of pipe diameter,so the reasonable selection of prefabricated direct-buried heating pipeline ensures the lowest total cost.Taking the heat supply design of a thermal power plant to surrounding cities as an example,this paper analyzes the optimal configuration of prefabricated direct-buried heat supply pipeline,puts forward the concept of annual total cost from the perspective of financial analysis,and introduces the calculation method of each parameter.The result shows that when the interest rate is 8%,we can get the average annual total cost of the minimum corresponding diameter ofφ1120*16 by calculation.
