摘　　要：燃气燃烧器广泛应用于采暖锅炉和工业加热中。在东南沿海某地区多气源互换性问题的背景下,选择了市场上3台小功率燃气燃烧器,以LNG1为基准气,实验测试了其在6种不同组分天然气下的热工性能响应。测试结果表明:3台小功率燃气燃烧器在贫气下热负荷不达标,华白数可以较好地预测不同组分天然气下的热负荷变化情况;NO x排放无显著变化,CO排放基本处于国标允许的范围内;火焰形态未呈现较大变化——天然气组分的变化未对控制系统造成影响。Under the background of multi-source natural gas interchangeability in the southeast region, LNG1 as reference gas, three low power gas burners were selected to test the thermal performance of 6 kinds of natural gases with different components. Results showed that: Three low power gas burners' heat loads were below standard value under the condition of lean gas. Wobbe index could be used to predict gas burners' heat load change under different gas components. CO, NO x emissions were within the allowable national standard range and flame shapes had not a great change----the change of natural gas did not affect the control system.
