六盘山热电联供热网关键技术

Key Technologies of Liupanshui Heat and Power Cogeneration Heat-supply Network

结合六盘山热电厂热电联供项目,对热网关键技术进行探讨。对直埋供热管道安装方式(有补偿安装、无补偿冷安装、无补偿预热安装)进行比选,对穿越河流、地震断裂带等特殊节点供热管道的处理方法进行分析。

Combined with the heat and power cogeneration project of Liupanshan Thermal Power Plant, the key technologies of the heat-supply network are discussed. The installation methods of directly buried heating pipeline （installation with expansion, cool installation without expansion and preheating installation without expansion） are compared and selected, and the treatment methods of the heating pipeline at the special nodes like crossing of river and earthquake fault zone are analyzed.
