“…Whereas at an equivalent ratio of 0.9, the mixture of fuel and air approaches the stoichiometry point and produces the most ideal reaction speed and angle of flame. The data above was in line with the research before, run by Wardana [33] and Pambudi [14] which explains that premixed combustion requires air within the process (φ<1). Then, at an equivalent of 1.2, the lowest laminar flame speed was shown, because at these conditions the combustion was dominated by fuel so that the fuel did not burn completely.…”

Nyamplung (Calophyllum Inophyllum) is an environmentally friendly alternative fuel that can be used to replace the consumption of fossil fuels. The purpose of this experiment was to analyze the effect of magnetic fields on the premixed flame of biodiesel from Calophyllum Inophyllum, the experiments were carried out on a bunsen burner. Fuel evaporation uses a temperature of 473 K and the equivalent ratio used is between ϕ 0.7; 0.8; 0.9; 1.0; 1.1 and 1.2. This experiment used a modified magnet that has magnetic force in 11.000 gausses with magnetic variations N-S, S-N, N-N, and S-S. Experiments revealed that magnetic fields have a significant effect to increase the value of laminar flame speed on magnetic variations point at S-S 3.8%; N-N 4.8%; S-N 17.09%, and the highest laminar flame speed were at point N-S 20.7%. The enhancement value of laminar flame speed indicated more optimum combustion processes. The magnetic fields can influence the O2, and H2O and change the orientation of the hydrocarbons which makes it easier for O2 and fuel to carry out the oxidation process, resulting in more optimal combustion.

“…Readers are kindly advised that syngas and producer gas are used interchangeably in some literature to refer to a mixture that mainly consists of H 2 , CO and CH 4 , and other noncombustible gases, or tar and particulate matter. 27 Readers could refer to the original references to understand the contexts written by the original authors. However, when not referring to other works, we define syngas in the current numerical study as a mixture that only consists of CO and H 2 (cf.…”

The maximum water as a diluent in the nonpremixed flame is quantified, mimicking combustion cooling by evaporation. Simulations with Cantera, using established chemical mechanisms, were conducted with various mass flux rates of fuel, equivalence ratios, fuel compositions, pressures, and inlet temperatures of the fuel. More water and lower flame temperature promote the forward reaction H + O 2 + (M) ↔ HO 2 + (M) but demote H + O 2 ↔ O + OH. Eventually, the heat generated by the first of these reactions could not compensate for the reduced contribution from H + OH + M ↔ H 2 O + M, making the flame unable to sustain itself. A linear dependency was found between the flammability limit and the strain rate of the flame. The fuel composition and inlet temperature presented an insignificant impact on the flammability limit. Higher pressure prevented the flame from extinction as more water was added to the oxidizer. Under the reference configuration, the flammability limit was found at an H 2 O mole fraction of 0.75 in the oxidizer.
