The Effect of Magnetic Field on Premixed Flame of Biodiesel Fuel Calophyllum Inophyllum B0, B50, and B100

This study analyzes the effect of magnetic fields on premixed flame behavior in a bunsen burner. The fuel used is pure Calophyllum Inophyllum (B100), a mixture of Calophyllum Inophyllum with diesel oil (B50) and pure diesel oil (B0) which is heated to a temperature of 553 (K). The test uses variations of magnetic field poles N-S, S-N, N-N, and S-S, with variations in equivalent ratios of 0.7, 0.8, 0.9, 1, 1.1, and 1.2. The experimental results reveal that the magnetic field can affect the premixed flame behavior by analyzing the RGB color intensity and laminar burning velocity. In the flame of the B100 fuel, the intensity of the red color decreases when it is influenced by a magnetic field. The highest reduction in red color intensity occurred at the variation of the N-S magnetic poles at an equivalent ratio of 0.7. From non-magnetic B100 fuel, the average laminar burning velocity in all variations of the equivalent ratio with the influence of the N-S magnetic field increased by 28.81%, on non-magnetic B50 fuel by 34.78%, and B50 N-S fuel by 46.96%. The improvement in the quality of combustion under the influence of a magnetic field is caused by the movement of O2 around the magnetic field which becomes more active towards the combustion reaction zone and the weakening of the bonds between hydrocarbon molecules which causes O2 to bind more easily to the hydrocarbons so that the combustion becomes more optimal.
