“…Meanwhile, diffusion combustion occurs due to incomplete combustion in premixed combustion, so that some of the fuel does not burn and is then oxidized by the surrounding air to form diffusion combustion. The ideal ratio between fuel and air greatly influences the stability of the flame [39,41]. From the flame photos obtained, analysis was carried out on the RGB color formed, laminar burning velocity, and flame height.…”

The problems facing the world today are limited fossil fuels and increasing global warming due to fuel emissions. Therefore, there is a need to transition from fossil energy to alternative energy that is environmentally friendly and renewable. Biodiesel is an alternative material that can be used as a substitute for diesel fuel. This research aims to improve the combustion quality of calophyllum inophyllum biodiesel using the magnetic field influence method. The combustion test method uses a Bunsen burner and variations in magnetic strength of 4000 gauss, 8000 gauss and 12000 gauss are given. The equivalent ratios used in combustion analysis are 0.6:1, 0.7:1, 0.8:1, 0.9:1, 1:1, 1:1.1, and 1:1.2. The fuel and air flowing in the Bunsen pipe are heated to a constant temperature of 250°C for the fuel evaporation process. Then the resulting flame was analyzed for its combustion characteristics with RGB color variables, laminar burning velocity, and flame height. The research results show that the stronger the magnetic field effect, the more optimal the combustion quality will be. This is indicated by the increasingly strong magnetic field effect exerted on the flame, causing the red color intensity to decrease, the laminar burning velocity to increase, and the flame height to decrease. This is because the magnetic field can influence the movement of O2 molecules and cause a change in the orientation of the hydrocarbon from para to ortho. As a result, diffusion combustion becomes minimal and the combustion reaction becomes faster.

“…So that the red color of the flame can be used as a parameter to determine the quality of combustion. The equivalent ratio plays a very important role in influencing the optimal or failure of a combustion process [19]. Figure 9 shows the results of measuring the intensity of the red color on the flame of B100 fuel.…”

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.

“…The flame comprises two reaction zones: an internal premixed flame that converts fuel to CO and H2, and an external diffuse flame that further oxidizes CO and H2 to produce combustion [32]. The flame's structure varies at equivalent ratios of 0.5, 1, and 1.5, with the equivalent ratio having a significant influence on whether the combustion process succeeds or fails [15]. An equivalent ratio of 1.5 indicates a higher flame structure and some diffusion combustion at the tip of the flame.…”

“…Additionally, high viscosity negatively impacts injector spray atomization, while also impeding the formation of a fuel-air mixture by slowing down evaporation [12]. Moreover, fuel density plays a role in its combustibility, and high-density fuel is harder to burn, leading to reduced heat generation [15]. Meanwhile, a higher flash point causes the fuel to require a longer burning time.…”

The study objective is to investigate the combustion characteristics of Callophyllum inophyllum fuel in presence of a magnetic fields. To conduct the experiment, a bunsen burner was utilized, with fuel and air being dispensed via a syringe pump and compressor, both regulated by a flowmeter. The fuel and air pipes were heated to 532.15 (K) to facilitate fuel evaporation. The equivalent ratio of 0.5, 1, and 1.5 was adjusted to control air discharge and fuel. An 11,000 gausses artificial magnet was used, with N-S, N-S, N-N, and S-S being the various magnetic pole configurations. The study found that the magnetic field can enhance combustion quality by affecting the molecules involved in the combustion process. The magnetic field's force also intensifies the movement of O2, making it more energetic. As O2 travels from the North Pole to the South Pole through the combustion reaction zone, it quickens the oxidation-reduction process and curtails diffusion combustion. The red color's intensity diminishes with the magnetic field's effect, indicating this phenomenon. When a magnetic field is applied, the polarity of C.inophyllum biodiesel fuel becomes highly favorable. The triglyceride carbon chain bonds become unstable, and the van der Walls dispersion forces are weakened, which facilitates easier O2 binding to the fuel, resulting in more efficient combustion. An increase in the laminar burning velocity value can be noticed when exposed to a magnetic field.
