Abstract: This research focuses on the enlarging the axial burner scale especially on inverse diffusion flame burner (IDF) with natural gas as the fuel by study of dimensional analysis, similarity, and numerical model. To analyses the similarity of difference burner scales by simulation study, the obtained simulation results were compared to the experimental previous study with around 8.5% of difference. In this study, there are four types of simulation results on firing rate for study of burner similarity, which consisted of the flame temperature, the temperature distribution, the flow distribution, and the average flow velocity. As the results, the burner dimension could be enlarged by the equation base on firing rate and the flame temperature predicting equation on firing rate 2.0 kW to 20.0 kW at equivalence ratio 1.0 with around 3.0% of difference. This research can be concluded that obtained dimensional analysis was appropriate method for enlarging the burner scale with similarity.
