초록

The reformer system is a method for hydrogen production from hydrocarbon fuels such as natural gas under high temperature environment($about{\sim}1,000^{\circ}C$). The premixed swirl burner with mixing swirler and combustion swirler designed to deliver fuel cell electric output from 0.5 kW to 1.5 kW. Premixed swirl burner experiments using natural gas and mixture of natural gas and anode off gas were carried out to analyse flame patterns and stability by equivalence ratio respectively. The results show that the stable swirl flame can be established for all cases of fuels type using the premixed swirl burner. The swirl flame had a wide stability region and it showed very low CO(50 ppm) and $NO_x$(20 ppm) emission at different fuel type and various equivalence ratio conditions. The operating range of premixed swirl burner for stable swirl flame is found to exist between equivalence ratio of 0.70 to 0.90 for turn down ratio of 3:1.
