摘　　要：随着世界各地液化天然气(LNG)市场的快速发展,美国、欧洲等国家纷纷针对各自情况对天然气互换性做了进一步研究,并给出了各自的研究结果。我国LNG需求量逐年增加,对其进网质量也在逐渐严格,但到目前为止,仍未形成一套系统完整的互换预测体系用于对进网天然气质量的控制。本文通过对17台具有代表性的燃气灶在11种气源情况下共187个工况点的响应测试,并结合AGA和Weaver指数法的预测结果,对其互换性的预测适用性进行研究。最终提出对Weaver指数法的CO生成指数JI和离焰指数JL以及AGA离焰指数IL进行适当修正,建议将其可互换范围分别调整为JI≤0.04,JL≥0.95和IL≤1.05。LNG has been steadily increasing its share of the global gas trade.The United States and European countries have studied the interchangeability of natural gas according to specific situations and provided results of the relevant studies.In China,the import of LNG is steadily increasing,but the problems regarding quality and interchangeability were not fully understood and resolved.In this paper,a study on applicability of Weaver indices has been completed.The experiments were conducted for 17 typical gas appliances and 11 natural gas sources with 187 test conditions.Comparing the experimental results with the results predicted by Weaver indices,it suggested that the limits of Lifting JL need to change to ≥0.95,Incomplete Combustion JI need to change to ≤0.04 and the limit of AGA index Lifting IL change to ≤1.05.
