随着天然气越来越多地应用于城市燃气系统,许多城市都将出现多种气源并存的格局.为此,介绍了多气源天然气互换性问题的由来及其可能产生的影响、常见的互换性判定方法和技术路线;追溯了LNG热值较高的历史原因;总结了国外天然气互换性问题的具体解决办法;分析了我国多气源天然气互换性研究的现状.最后提出了借鉴国外经验合理解决我国目前多气源天然气互换性问题的对策:加快确立相关行业标准,因地制宜地设定"适应多气源燃具的天然气设计基准参数",并据此合理引进气源,合理划分区域,按用户分类供气;同时应对燃具制造商提出"适应多气源燃具的设计要求",对未来入市的燃具提出明确要求.据此对现有天然气利用设备进行改造或调整,以顺利解决天然气互换性问题.

Since being more and more widely used for combustion end uses in many cities of China, natural gas from different sources with different qualities is supplied at the same time for the same city. Therefore, this paper introduces the origin and potential bad effects of gas interchangeability in the gas supply system, the commonly-used discriminating methods and technical measures, dates back to the historical reason of high heating value of LNG, summarizes the concrete solutions of gas interchangeability abroad, and analyzes the current status of study on natural gas interchangeability in China. By learning good experiences from other countries, it finally makes the following suggestions for dealing with gas interchangeability in Chinese urban gas supply system: a. the related standard should be set up for natural gas market, and natural gas should be reasonably supplied according to differently divided regions and differently classified end users; the designed reference parameters should be determined for combustion burners more adaptable for differently sourced gases, the design requirements should be specified for combustion burner manufacturers, and the traditional end use equipments should be transformed and adjusted to meet the current need.
