大直径、长距离供热蒸汽管线的经济设计(续篇)

Design for Economy of Large Diameter and Long Distance Steam Pipelines for Heating Purposes

本文从技术经济角度分析了集中供热输送距离对经济性的影响,推导出了极限输送距离的经济性和可行性判别公式,与经济直径相配合,完善了整体经济设计的理论探索。

In this article from the viewpoint of engineering economy, the effect of the heat conveying distance on economy is analyzed and formulas for judging the economy ond feasibility of the limiting conveying distance are derived. This in conjunction with the economical diameter consummates the theoretial exploitation on the design for integral economy.
