成都市天然气现有管网输气能力分析与提升策略

摘要

随着城市的发展及清洁能源需求的增加，要求建立一套完善的保障天然气安全稳定供应的燃气管网输配系统。结合成都市天然气管网运行现状和未来天然气发展规划，系统分析了提高管网输气能力的方法。%Due to the rapid development of urban construction and increasing requirement of clean energy, there is a contradiction between limited land resources and a large number of natural gas infrastructures. On the basis of the analysis of present running status and future development planning of natural gas in Chengdu, methods of improving pipe network transmission capacity are systemically analyzed in this paper. Such as improving the pipeline operating pressure, transferring low pressure to medium pressure, enlarging pipe diameter, adding source point, increasing parallel lines.
