城市应急备用气源的燃气互换性探讨

Discussion on Interchangeability of City Emergency Stand-by Gas Source

通过对不同情况下的液化石油气混空气、液化天然气、液化天然气混空气与忠县天然气混合后的混合气的华白数、燃烧势进行计算,分析其与城市主气源忠县天然气的燃气互换性,探讨了液化石油气混空气和LNG作为城市燃气应急备用气源的可行性。

Through calculating the Wobbe index and combustion potential of the mixture of LPG- air mixture, LNG and LNG-air mixture with Zhongxian natural gas under different conditions, the interchangeability between the mixture and the main gas source （Zhongxian natural gas） is analyzed, and the feasibility of LPG-air mixture and LNG as city emergency stand-by gas source is discussed.
