摘　　要： 基于广州市现有燃气系统的特点,提出了采用过渡气源的办法,用天然气分步置换广州城市燃气的新思路。分别设计了过渡气1和过渡气2两种过渡气源,并采用国际流行的AGA法从理论上对过渡气源与现有城市煤气的互换性进行了计算。结果表明两种过渡气都能满足互换,且在相同华白数的时候,过渡气2具有更好的燃烧工况。 A new method that natural gas substitute city gas step by step with an intermediate gas was pointed out based on characteristics of existing fuel gas system in Guangzhou. Two kinds of intermediate gas that are gas 1 and 2 were designed, and then the interchangeability between these two gas and vested town gas was evaluated by popular AGA indices on theory. The result was that both of the two intermediate gases can meet the need of substitution and gas 2 would have a better combustion conditions than gas 1 when they had the same W value.
