摘　　要：以管道天然气混氢气代替合成天然气,通过计算分析和实验测试研究全预混金属纤维燃烧器对合成天然气的适应性。介绍混气工艺、实验设备和方法,分析混氢比例对全预混燃烧器的热负荷、燃烧稳定性以及排放特性的影响。结果表明,华白数的变化基本反映了热负荷变化的规律;合成天然气在全预混金属纤维燃烧器上燃用,基本不会出现稳定性问题;全预混金属纤维燃烧器在燃用合成天然气时,排放性能不会下降。The synthetic natural gas is substituted by blending pipeline natural gas with hydrogen, and the adaptability of the fully premixed metal fiber burner to the synthetic natural gas is studied by means of computational analysis and experimental tests. The gas blending process, the experimental equipment and the method are introduced, and the effect of hydrogen blending ratio on the heat load, combustion stability and emission characteristics of the fully premixed metal fiber burner is analyzed. The results show that the change of Wobbe index basically reflects the law of the heat load change. There is no stability problem when the synthetic natural gas is burned in the fully premixed metal fiber burner. The emission performance of the fully premixed metal fiber burner does not decline when the burner burns the synthetic natural gas.
