备注

多气源供气是城市燃气未来发展的必然趋势,为了确保用户安全、环保地利用各类燃气,需要制定燃气互换原则。以北京市多气源供气格局为例,选取典型大气式燃气具,利用高精度动态配气系统配制模拟气源,实验测定燃气具的气质适应性区域。结果 表明:部分燃气具会出现CO 排放超标的现象,需采取相应的规避措施;北京市远期规划LNG 气源全部分布在北京市燃气具互换域之外,若直接与北京市基准气进行置换,会造成大部分居民用户灶具CO 排放超标,不可互换;北京市其他规划气源全部分布在互换域之内,可以互换。研究结果可为国内外城市的燃气互换实践和燃气企业的生产经营活动提供必要的参考。(图7表4,参[25]

Multi-source gas supply is an inevitable trend for the future development of city gas, so it is necessary to formulate the principle of gas interchangeability in order to ensure the safe and environmental usage of all kinds of gas. In this paper, the typical atmospheric gas appliances were selected by taking Beijing’s multi-source gas supply pattern as an example. The simulated gas source was prepared using the high-precision dynamic gas distribution system, and the adaptability area of gas appliances from the aspect of gas quality was experimentally measured. It is shown that some gas appliances present the phenomenon of excessive CO emissions, so the corresponding measures shall be taken to avoid potential hazards. The long-term planned LNG sources in Beijing are distributed outside the gas appliance interchange areas of Beijing. If they are directly replaced with the reference gas of Beijing, the gas appliances of most residents will produce excessive CO emissions, indicating that the gas interchange is unavailable. The other planned gas sources in Beijing are all distributed in the interchange areas, indicating that the gas interchange is available. The research results are expected to provide a certain reference for the practical gas interchange in domestic and foreign cities and the production and operation of gas enterprises.
