This study used an experimental method by directly observing the object under study. The independent variables in this study include the geometry of the flame holder on the meso-scale combustor, airflow, and fuel discharge. The research data were analyzed and displayed in graphical form as well as flame visualization. This research concludes that combustion using a flame holder circle has a more stable and even flame compared to a flame holder concentric ring and backward facing step. The shape of the Flame holder circle also produces a higher flame temperature. The results of this study contribute to the development of MPG based on micro combustion with a better understanding of the interaction between flame holders, reactant velocities and equivalent ratios in achieving stable and efficient combustion in meso-scale combustors. This research can provide important input for the development of high-efficiency micro-combustion-based power generation technology in the future.
