Abstract

This study investigates an effects of various magnetic fieldsdirection on flames characteristic of premix combustions. Research is important as a reserve a fossil fuel using environmental friendly vegetable oil.Jatrophacurcas oil is mixed with cotton seeds (50% blend) as fuel.Experimentare carried out on cylindrical type burner. Vegetable oils were loaded on boiler, then heated on LPG stoves, while air was obtained from the compressor. Grade N52 nickel neodymium magnets atintensitymagnetic fieldsof 1.1 T were used in this study. The combustion characteristics are identified from the flame image and the temperature signal at the burner tip. The flame image is recorded using a video camera at highspeed, 120 frames per second. This research found that the magnetic field of an attractive produces a brighter, wider, and more stable flame compared to a repulsive magnet and without. The magnetic field changes the orientation of the hydrocarbon from the para state to the ortho state, so that it tends to break down the fuel molecules resulting in more complete and faster combustion causing the flame temperature to increase, but the flame height decreases.

Abstract

This study aimed to determine effect of oxygen enrichment and magnetic field direction on the flame behavior kapok oil combustion. Experiment was carried out to obtain flame evolution, temperature and height. Kapok oil (600 ml) was put in the boiler, and heated to 300°C. A burner chamber is placed for the reaction between kapok oil vapor with air from compressor and oxygen. Two permanent magnets of neodymium nickel grade N52 with intensity 1.1 Tesla were placed on side of burner tip. Results showed the magnetic field produce more transparent, slimmer flames with highest temperature of 679°C, lowest flames height of 5 mm. Magnetic fields produce a Lorentz force that breaks the fuel chemical chain and creates magnetic pulses in the flames. Oxygen contained in air around the burner coupled with oxygen enrichment create excessive oxidizing gas to separate and release electrons. Excessive oxygen results in a higher flame temperature due to faster combustion reaction. The magnetic fields around flames induces flow air which magnetically cause heat transfer around the flame, resulted variable flame height. This combustion produces different flame evolution, temperature, and height. Keywords: Flames behavior, Flames colour, Kapok oil, Magnetic field, Premixed combustion.
