This article describes a comparison investigation on the laminar burning velocities measurement methods of simulated synthetic natural gas(SNG). In this study, there were used three ways to compare the measuring method. First method was an angle method of Bunsen flame, next method was an adjustable area method using an annular diverging channel combustor, final method was a unstretched flat flame using a counter-flowing combustor. These results were also compared with numerical calculation by CHEMKIN package with USC-Ⅱ and GRI 3.0 mechanism . As an experimental conditions, hydrogen content was 3% and equivalence ratios was adjusted from 0.8 to 1.4. From results of this work, it was we found that the burning velocity of SNG fuel was the fastest in equivalence ratio of 1.1 and the various measurement methods had similar trends.
