Abstract

When the heating pipelines have a large height difference on the way of laying, which is lead to increase the resistance of heating network and make hydraulic regime complicated. This paper presents a feasibility study of the long-distance heating pipeline project from Yangcheng Power Plant in Shanxi Province to Jincheng city which is carried out through the comparative analysis of the hydraulic pressure diagram. According to the optimal route, the following four schemes are proposed: (1) First-stage pressurization of the first station. (2) Multi-stage pressurization of relay-pump station. (3) Setting up intervals-pressure heat exchange station. (4) Combination of relay-pump station and intervals-pressure heat exchange station. The advantages and disadvantages of them are analyzed, respectively. As a result, only Scheme 4 meets the requirements of hydraulic conditions and the optimal location of the relay-pump station is determined be 9550 m away from the first station. This paper is intended to contribute a solution to the long-distance central heating with large height difference.
