Abstract

Diffusion is performed combustion in diesel engines, biodiesel as a biofuel that is used to replace fossil fuels. Many studies have looked at the effects of a mixture of biodiesel fuel ethanol-methanol-diesel with different percentages in terms of engine performance and exhaust emissions, but have never done research on combustion characteristics. This paper discusses how the mix ratio diffusion combustion characteristics of biodiesel - ethanol / methanol on a mini glass tube burner and a mini copper tube burner. the results showed that the use of mini glass tube burner produces more explosions flame than mini copper tube burner. This is because the temperature of the mini copper tube is higher than the temperature of the mini glass tube, and fire explosion occurred because of thecohesionof theglasstubeto thefuel, so that theliquid fueloftenjumpoutofthe burner tipand thenthere was an explosionof fire, and alsocoolingthe fuelvaporwhen passing theminiglasstube. The lower of viscosity and boiling point properties can reduce explosion flame, and making the evaporationfuelmore better. Conclusion, the use ofmini copper tube burner, producesmore stable flamethanmini glass tube burner. and properties of biodiesel-methanol is better than biodiesel-ethanol. Keywords :Biodiesel, diffusion flame, combustion characteristics, mini glass tube burner, mini copper tube burner.

Abstract

Diffusion is a combustion which is performed on a diesel engine, biodiesel as a biofuel is used to replace fossil fuels. Many studies have looked at the effect of a mixture of biodiesel fuel-ethanolmethanol-diesel with different percentages in terms of engine performance and exhaust emissions, but have never done research on the characteristics of combustion and interface evaporation. This paper discusses how the comparison of the characteristics of the diffusion combustion mixture of biodiesel and biodiesel-ethanol-methanol in mini glass tube. The results showed that the use of biodieselethanol occurred many explosions flame and lift off than biodiesel-methanol. Biodiesel-ethanol evaporation interfaces tend to be flat because there were many explosions so that the liquid fuel out of the burner. The use of biodiesel-methanol flame produces more stable than biodiesel-ethanol.
