Flame Characteristics of Diffusion of Calophyllum inophyllum Methyl Ester on Mini Glass Tube

Abstract

Combustion is a chain chemical reaction that is influenced by three factors, namely fuel, oxidizer, and heat. This study analyzes the effect variations of fuel flow rates (1 ml/h, 2 ml/h, and 3 ml/h) on the laminar burning velocity, flame height and flame stability as seen from the number of explosions. This study uses Calophyllum inophyllum methyl ester fuel. In the diffusion combustion process, the fuel mixes with the oxidizer naturally. In this study, it is known that the flow rate of 1 ml/h produces the highest average laminar burning velocity value of 0.0023 m/s and the lowest laminar burning velocity value is 0.0020 m/s at the flow rate of 3 ml/h. Whereas for the height of the flame has the highest average value at the flow rate of 3 ml/h which is 27.98 mm and the lowest average high flame value at the fuel flow rate of 1 ml/h is 2.9 mm.
