The reformer system is a method for hydrogen production from hydrocarbon fuels such as natural gas underhigh temperature environment(about~1,000℃). The premixed swirl burner with mixing swirler and combustionswirler designed to deliver fuel cell electric output from 0.5 kW to 1.5 kW. Premixed swirl burner experimentsusing natural gas and mixture of natural gas and anode off gas were carried out to analyse flame patternsand stability by equivalence ratio respectively. The results show that the stable swirl flame can be establishedfor all cases of fuels type using the premixed swirl burner. The swirl flame had a wide stability region andit showed very low CO(50 ppm) and NOx(20 ppm) emission at different fuel type and various equivalenceratio conditions. The operating range of premixed swirl burner for stable swirl flame is found to exist betweenequivalence ratio of 0.70 to 0.90 for turn down ratio of 3:1.
