燃气互换性判定方法综述

An Overview of Gas Interchangeability Prediction Methods

随着天然气事业的快速发展,各种来源的天然气开始接入管网系统,组分差异导致的燃烧不稳定问题近来成为讨论热点。该文系统地介绍了国外各种常用的互换性判定方法,并简要说明其对应的研究背景和适用范围。指出互换性问题是一个因器具结构、检测与判定标准而不断发展的问题,我国的天然气互换性研究有必要深入开展。

With rapid development of natural gas industry,it becomes more and more common that natural gases from different sources are introduced into the same network system.Variations of natural gas which may lead to combustion instabilities are frequently focused.Prediction methods which are widely used in other countries,and their applicability scope and development backgrounds,were systematically introduced in this paper.It was pointed out that gas interchangeability problem is a technical issue in progress,depending upon appliance structure and popularity and related standards.The interchangeability of natural gases in China remains to be thoroughly explored.
