城市燃气调峰与安全供用气

On Peak Shaving and Stable Gas Supply and Demand for City Gas

城市燃气供应因存在小时、日、月用气不均衡的特点,因此要求长输天然气管道具有一定的调节能力,且须妥善解决调峰问题。介绍了管道末段储气、地上储气罐、地下储气库、LNG调峰厂、地下管束及其他调峰方式,分析了各自的优缺点。提出了解决城市燃气调峰与安全供用气问题的综合措施和建议。

The supply of city gas is characterized by disequilibrium in hour, day and month. Therefore, the long distance gas pipeline must be designed with a certain ability in pressure adjustment, that is, in peak shaving. The authors present six peak shaving methods , that is , final section line-packing, above-ground gas tank, underground gas storage,LNG peak shaving plant, underground bundled tubes and other peak shaving technique. The comparison on the six methods is made to expound the advantages and shortcomings between them. The measures and suggestions to make peak shaving and to ensure stable gas supply and demand for city gas are given in the paper.
