Analysis of characteristic of combustion flame from biogas fuel mixed with butane

Abstract

The rapid use of fossil energy makes the supply of fossil fuels decreasing every year. One of alternative energies which can be developed in the rural area of Indonesia is biogas. In this study, the biogas will be mixed with fuel which has a higher heating value, namely butane. The method used is comparing the characteristics of pure biogas fire, biogas mixed with 10% -50% butane and pure butane using bunsen burner with premixed combustion. The characteristics of flame observed during the research is the color, cone and temperature of flame using bunsen burner with premixed combustion. Based on the result of the study about the color, cone and temperature of flame, there is an increase in every addition of butane. The increase is caused by the energy released by the higher fuel in each butane addition. Based on those things, it can be concluded that the addition of butane to biogas can improve the quality of biogas.
