Characterization of Premixed Flames with Ethanol Fuel affected Magnetic Field Induction

The purpose of this study was to determine the effect of magnetic field induction on the characteristics of premixed ethanol combustion flames. Petroleum reserves will increasingly be depleted if alternative energy is not found. Therefore, various breakthroughs are needed to prevent an energy crisis from occurring. Simultaneously the researchers are also trying to find equipment that can save fuel consumption. To get a more effective and efficient flame, you can apply a magnetic field effect to the burning fire, especially in terms of the rate of burning of the fire. Fuel oil under normal conditions tends to be irregular and grouped together. By providing a magnetic field to induce the fuel oil, the hydrocarbon bonds will break and will make the chemical composition more homogeneous. The experimental research method is to heat ethanol until it is in the form of steam, then flow it to the burner which will then be given air which is controlled by the mass flow. The research began with the manufacture of magnetic induction from carbon steel wrapped in copper wire. Then testing the fuel by providing a magnetic field before the ethanol fuel enters the burner tip. The magnetic field helps the fuel ionization process, this ionization is needed so that the fuel can easily bind oxygen during the combustion process. If the ionization process goes well then the combustion process becomes more complete. In this ionization process, it will result in the formation of positively charged fuel molecules so that during combustion the combustion process will occur more quickly. The magnetic field will generate Far Infrared waves, which will strengthen the positively charged bonds in the fuel structure due to the ionization process and position these bonds in an orderly manner. This makes it easy for oxygen to react with fuel in the combustion process. With the electric motion force will increase the combustion temperature. The increase in temperature is caused by the process of ionization of the fuel due to the magnetic field generated by the electromotive force. The dynamic electromotive force causes the flame to increase when the current is flowing and decrease when the electric current is cut off. The resulting fire is more transparent, clearer and more visible. The direction of the N-S magnetic field causes the temperature to be higher than the direction of the N-N magnetic field. The magnetic field can affect the burning speed of the ethanol flame. In a poor mixture (ϕ <1) in the presence of magnetic influence, the rate of fire is lower without the influence of a magnetic field, but in a rich mixture (ϕ > 1) in the presence of a magnetic influence, the rate of fire is higher than without the influence of a magnetic field.
