摘要
对燃气类别和特性指标进行研究,提出GB/T 13611—2006《城镇燃气分类和基本特性》的修订建议。建议将我国燃气划分为6大类,液化石油气混空气、二甲醚、沼气单列归类;采用燃气华白数、热值等国际通用参数,对燃气进行分类和特性鉴别;以CH4、H2、N2三组分配制人工煤气;以甲烷为主,采用甲烷、氮气、商品丙烷或丁烷配制天然气。实验研究认为,燃气互换性与燃具燃烧方式有关。
The classification and characteristics index of city gas are studied, and suggestions for revi- sing the Classification and Basic Characteristics of City Gas（GB/T 13611 - 2006） are proposed. It is sugges- ted that city gas in China should be divided into six categories, and LPG - air mixture, DME and biogas are alone classified as a single category. The Wobbe Index and calorific value commonly used worldwide are used to classify and indentify city gas. The manufac- tured gas can be made of three components of meth- ane, hydrogen and nitrogen. The natural gas can be synthesized by three components of methane, nitrogen and propane or butane. The experimental study shows that the gas interchangeability is related to the combus- tion mode of gas appliances.
