上海市多气源天然气互换性问题初探

介绍上海四大气源天然气质量的主要指标，针对这些气源的组分和物理特性，结合判断互换性的指标：华白数、多重指数和燃烧势，对上海多气源条件下的天然气互换性问题进行探讨，并提出部分对策和建议。

Initial Probe into Interchangeability of Multi-Source Natural Gas in Shanghai

Main norms of quality of natural gas in Shanghai from four sources are introduced. Aimed at composition and physical properties of these gas sources,combined with identification of interchangeability of their norms,for instance,wobbe number,multi-index and combustion potential,the interchangeability of natural gas under the condition of Shanghai multi-source is probed and some countermeasures and suggestions are made.
